這篇文章主要講解使用eclipse對Spirng+SpringMVC+Maven+Mybatis+MySQL項目搭建過程，包括裏面步驟和裏面的配置文件如何配置等等都會詳細說明。html

接下來立刻進入項目搭建過程：java

一、建立表，並插入數據：

CREATE TABLE `t_user` ( `USER_ID` int(11) NOT NULL AUTO_INCREMENT, `USER_NAME` char(30) NOT NULL, `USER_PASSWORD` char(10) NOT NULL, PRIMARY KEY (`USER_ID`), KEY `IDX_NAME` (`USER_NAME`) ) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8

INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD) VALUES (1, 'luoguohui', '123456'); INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD) VALUES (2, 'zhangsan', '123456');

二、Maven工程建立

三、選擇快速框架

四、輸出項目名，包（Packaging，若是隻是普通的項目，選jar就行了，若是是web項目就選war，這裏是web項目，因此選擇war）

五、建立好的目錄以下：

六、添加包的依賴，編輯pom.xml文件添加以下依賴：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.luo</groupId> <artifactId>first_maven_project</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <properties> <!-- spring版本號 --> <spring.version>3.2.8.RELEASE</spring.version> <!-- log4j日誌文件管理包版本 --> <slf4j.version>1.6.6</slf4j.version> <log4j.version>1.2.12</log4j.version> <!-- junit版本號 --> <junit.version>4.10</junit.version> <!-- mybatis版本號 --> <mybatis.version>3.2.1</mybatis.version> </properties> <dependencies> <!-- 添加Spring依賴 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <!--單元測試依賴 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>${junit.version}</version> <scope>test</scope> </dependency> <!-- 日誌文件管理包 --> <!-- log start --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency> <!-- log end --> <!--spring單元測試依賴 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> <scope>test</scope> </dependency> <!--mybatis依賴 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <!-- mybatis/spring包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.0</version> </dependency> <!-- mysql驅動包 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.29</version> </dependency> </dependencies> </project>

七、配置文件：

7.一、mybatis包下添加mybatis-config.xml文件（mybatis配置文件）：mysql

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> </configuration>

7.二、properties包下添加jdbc.properties文件（數據源配置文件）：web

jdbc_driverClassName=com.mysql.jdbc.Driver jdbc_url=jdbc:mysql://localhost:3306/luo jdbc_username=root jdbc_password=root

7.三、mapper包下userMapper.xml配置文件（表映射文件）：spring

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.luo.dao.UserDao"> <!--設置domain類和數據庫中表的字段一一對應，注意數據庫字段和domain類中的字段名稱不致，此處必定要！--> <resultMap id="BaseResultMap" type="com.luo.domain.User"> <id column="USER_ID" property="userId" jdbcType="INTEGER" /> <result column="USER_NAME" property="userName" jdbcType="CHAR" /> <result column="USER_PASSWORD" property="userPassword" jdbcType="CHAR" /> </resultMap> <!-- 查詢單條記錄 --> <select id="selectUserById" parameterType="int" resultMap="BaseResultMap"> SELECT * FROM t_user WHERE USER_ID = #{userId} </select> </mapper>

7.四、spring配置文件application.xml：sql

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <!-- 引入jdbc配置文件 --> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <list> <value>classpath:properties/*.properties</value> <!--要是有多個配置文件，只需在這裏繼續添加便可 --> </list> </property> </bean> <!-- 配置數據源 --> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <!-- 不使用properties來配置 --> <!-- <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://localhost:3306/learning" /> <property name="username" value="root" /> <property name="password" value="christmas258@" /> --> <!-- 使用properties來配置 --> <property name="driverClassName"> <value>${jdbc_driverClassName}</value> </property> <property name="url"> <value>${jdbc_url}</value> </property> <property name="username"> <value>${jdbc_username}</value> </property> <property name="password"> <value>${jdbc_password}</value> </property> </bean> <!-- 自動掃描了全部的XxxxMapper.xml對應的mapper接口文件，這樣就不用一個一個手動配置Mpper的映射了，只要Mapper接口類和Mapper映射文件對應起來就能夠了。 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.luo.dao" /> </bean> <!-- 配置Mybatis的文件 ，mapperLocations配置**Mapper.xml文件位置，configLocation配置mybatis-config文件位置--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="mapperLocations" value="classpath:mapper/*.xml"/> <property name="configLocation" value="classpath:mybatis/mybatis-config.xml" /> <!-- <property name="typeAliasesPackage" value="com.tiantian.ckeditor.model" /> --> </bean> <!-- 自動掃描註解的bean --> <context:component-scan base-package="com.luo.service" /> </beans>

八、接口和類的配置：

8.一、com.luo.domain下添加User.java文件：數據庫

package com.luo.domain;

public class User { private Integer userId; private String userName; private String userPassword; public Integer getUserId() { return userId; } public void setUserId(Integer userId) { this.userId = userId; } public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public String getUserPassword() { return userPassword; } public void setUserPassword(String userPassword) { this.userPassword = userPassword; } }

8.二、com.luo.dao下添加UserDao.java文件：apache

package com.luo.dao; import com.luo.domain.User; public interface UserDao { /** * @param userId * @return User */ public User selectUserById(Integer userId); }

8.三、com.luo.service下添加UserService.java接口和UserServiceImpl實現類：api

package com.luo.service; import com.luo.domain.User; public interface UserService { User selectUserById(Integer userId); }

package com.luo.service; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import com.luo.dao.UserDao; import com.luo.domain.User; @Service public class UserServiceImpl implements UserService { @Autowired private UserDao userDao; public User selectUserById(Integer userId) { return userDao.selectUserById(userId); } }

九、單元測試

9.一、com.luo.baseTest下添加SpringTestCase.java：spring-mvc

package com.luo.baseTest; import org.junit.runner.RunWith; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; //指定bean注入的配置文件 @ContextConfiguration(locations = { "classpath:application.xml" }) //使用標準的JUnit @RunWith註釋來告訴JUnit使用Spring TestRunner @RunWith(SpringJUnit4ClassRunner.class) public class SpringTestCase extends AbstractJUnit4SpringContextTests { }

9.二、com.luo.service添加UserServiceTest.java：

package com.luo.service; import org.junit.Test; import org.springframework.beans.factory.annotation.Autowired; import com.luo.baseTest.SpringTestCase; import com.luo.domain.User; public class UserServiceTest extends SpringTestCase { @Autowired private UserService userService; @Test public void selectUserByIdTest(){ User user = userService.selectUserById(1); System.out.println(user.getUserName() + ":" + user.getUserPassword()); } }

9.三、運行單元測試，UserServiceTest右鍵Run As –>Junit Test，運行結果：

下面加入springmvc，並轉換maven工程爲web項目

十、轉換成web項目：

若是上面webapp爲空的，說明這個項目還不是web項目：

接下來打開以下頁面。將紅框裏面的勾去掉，肯定（OK）：

而後從新打開剛剛那個頁面，把Dynamic web Module勾上，就會看到紅框的內容，點擊：

而後配置以下：

那麼webapp下就會生成這些東西：

十一、配置springmvc

11.一、pom.xml文件添加依賴，修改後配置以下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.luo</groupId> <artifactId>first_maven_project</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <properties> <!-- spring版本號 --> <spring.version>3.2.8.RELEASE</spring.version> <!-- junit版本號 --> <junit.version>4.10</junit.version> <!-- mybatis版本號 --> <mybatis.version>3.2.1</mybatis.version> </properties> <dependencies> <!-- 添加Spring依賴 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <!--單元測試依賴 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>${junit.version}</version> <scope>test</scope> </dependency> <!--spring單元測試依賴 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> <scope>test</scope> </dependency> <!--mybatis依賴 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <!-- mybatis/spring包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.0</version> </dependency> <!-- mysql驅動包 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.29</version> </dependency> <!-- javaee-api包 注意和項目使用的JDK版本對應 --> <dependency> <groupId>javax</groupId> <artifactId>javaee-api</artifactId> <version>6.0</version> <scope>provided</scope> </dependency> <!-- javaee-web-api包 注意和項目使用的JDK版本對應 --> <dependency> <groupId>javax</groupId> <artifactId>javaee-web-api</artifactId> <version>6.0</version> <scope>provided</scope> </dependency> </dependencies> </project>

其實也就增長了下面兩個

<!-- javaee-api包 注意和項目使用的JDK版本對應 --> <dependency> <groupId>javax</groupId> <artifactId>javaee-api</artifactId> <version>6.0</version> <scope>provided</scope> </dependency> <!-- javaee-web-api包 注意和項目使用的JDK版本對應 --> <dependency> <groupId>javax</groupId> <artifactId>javaee-web-api</artifactId> <version>6.0</version> <scope>provided</scope> </dependency>

11.二、在src/main/resource中添加springmvc文件夾，而後添加文件spring-mvc.xml，內容以下：

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:p="http://www.springframework.org/schema/p" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd"> <mvc:annotation-driven /> <!-- 掃描controller（controller層注入） --> <context:component-scan base-package="com.luo.controller"/> <!-- 對模型視圖添加先後綴 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/view/" p:suffix=".jsp"/> </beans>

11.三、配置web.xml

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>Archetype Created Web Application</display-name> <!-- 起始歡迎界面 --> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <!-- 讀取spring配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:application.xml</param-value> </context-param> <!-- 設計路徑變量值 --> <context-param> <param-name>webAppRootKey</param-name> <param-value>springmvc.root</param-value> </context-param> <!-- Spring字符集過濾器 --> <filter> <filter-name>SpringEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>SpringEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- springMVC核心配置 --> <servlet> <servlet-name>dispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <!--spingMVC的配置路徑 --> <param-value>classpath:springmvc/spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <!-- 攔截設置 --> <servlet-mapping> <servlet-name>dispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- 錯誤跳轉頁面 --> <error-page> <!-- 路徑不正確 --> <error-code>404</error-code> <location>/WEB-INF/errorpage/404.jsp</location> </error-page> <error-page> <!-- 沒有訪問權限，訪問被禁止 --> <error-code>405</error-code> <location>/WEB-INF/errorpage/405.jsp</location> </error-page> <error-page> <!-- 內部錯誤 --> <error-code>500</error-code> <location>/WEB-INF/errorpage/500.jsp</location> </error-page> </web-app>

11.四、添加index.jsp，在src/main/webapp/WEB-INF下新建一個文件夾view,添加一個index.jsp，內容以下：

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <html> <body> <h2>Hello World!</h2> 用戶名： ${user.userName}<br> 密碼：${user.userPassword}<br> </body> </html>

11.五、寫controller

在src/main/java下新建一個包com.luo.controller.而後新建一個類UserController.java,其內容以下

package com.luo.controller; import javax.annotation.Resource; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; import com.luo.domain.User; import com.luo.service.UserService; @Controller public class UserController { @Resource private UserService userService; @RequestMapping("/") public ModelAndView getIndex(){ ModelAndView mav = new ModelAndView("index"); User user = userService.selectUserById(1); mav.addObject("user", user); return mav; } }

11.6 運行！！！！完成！

十二、源碼下載

http://download.csdn.net/detail/u013142781/9376381

1三、可能會遇到的錯

以前有個兄弟按照個人配置，可是發現pom.xml文件報以下錯誤：

Cannot detect Web Project version. Please specify version of Web Project through <version> configuration property of war plugin. E.g.: <plugin> <artifactId>maven-war-plugin</artifactId> <configuration> <version>3.0<ersion> </configuration> </plugin>

解決方案是，以下的三個地方jdk版本須要保持一致：

一、項目右鍵->屬性->Java Compiler：

二、項目右鍵->屬性->Project Facets：

三、若是pom.xml配置了以下的插件的話：


 
 
 
 
 

  
  
  
  
  1

 
 
 
 
 
<build> <plugins> <plugin> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.7</source> <target>1.7</target> </configuration> </plugin> <plugin> <artifactId>maven-war-plugin</artifactId> <version>2.4</version> <configuration> <version>3.0</version> </configuration> </plugin> </plugins> <finalName>webserver</finalName> </build>
