2015/5/3~springMVC+mybatis+spring整合
1、準備工做html
一、概述java
springMVC+mybatis+spring+MySQL+log4j+mavenmysql
二、新建maven項目，如今web-app模版web
新建項目後，可能個別目錄會丟失，須要手動添加，總體目錄結構以下所示：spring
三、經過maven管理依賴，倉庫地址以下：sql

四、配置log4j數據庫
#定義LOG輸出級別
log4j.rootLogger=INFO,Console,File
#定義日誌輸出目的地爲控制檯
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#能夠靈活地指定日誌輸出格式，下面一行是指定具體的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n
#文件大小到達指定尺寸的時候產生一個新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定輸出目錄
log4j.appender.File.File = logs/ssm.log
#定義文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 輸出因此日誌，若是換成DEBUG表示輸出DEBUG以上級別日誌
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n
2、mybatis和spring整合，及單元測試apache
一、jdbc配置json
driver=com.mysql.jdbc.Driver url=jdbc:mysql://127.0.0.1:3306/test username=root password=123456 #\u5B9A\u4E49\u521D\u59CB\u8FDE\u63A5\u6570 initialSize=0 #\u5B9A\u4E49\u6700\u5927\u8FDE\u63A5\u6570 maxActive=20 #\u5B9A\u4E49\u6700\u5927\u7A7A\u95F2 maxIdle=20 #\u5B9A\u4E49\u6700\u5C0F\u7A7A\u95F2 minIdle=1 #\u5B9A\u4E49\u6700\u957F\u7B49\u5F85\u65F6\u95F4 maxWait=60000
二、配置spring_mybatis.xmlapi
<?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:p="http://www.springframework.org/schema/p"
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-3.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.1.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
<!-- 自動掃描 -->
<context:component-scan base-package="com.gzy.ssmTest" />
<!-- 引入配置文件 -->
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="classpath:jdbc.properties" />
</bean>
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="${driver}" />
<property name="url" value="${url}" />
<property name="username" value="${username}" />
<property name="password" value="${password}" />
<!-- 初始化鏈接大小 -->
<property name="initialSize" value="${initialSize}"></property>
<!-- 鏈接池最大數量 -->
<property name="maxActive" value="${maxActive}"></property>
<!-- 鏈接池最大空閒 -->
<property name="maxIdle" value="${maxIdle}"></property>
<!-- 鏈接池最小空閒 -->
<property name="minIdle" value="${minIdle}"></property>
<!-- 獲取鏈接最大等待時間 -->
<property name="maxWait" value="${maxWait}"></property>
</bean>
<!-- spring和MyBatis完美整合，不須要mybatis的配置映射文件 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<!-- 自動掃描mapping.xml文件 -->
<property name="mapperLocations" value="classpath:com/gzy/ssmTest/mapper/*.xml"></property>
</bean>
<!-- DAO接口所在包名，Spring會自動查找其下的類 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.gzy.ssmTest.mapper" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
</bean>
<!-- (事務管理)transaction manager, use JtaTransactionManager for global tx -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
</beans>
三、編寫測試方法
。。。
四、單元測試
package com.gzy.test.user;
import org.apache.log4j.Logger;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import com.gzy.ssmTest.model.User;
import com.gzy.ssmTest.service.IUserService;
@RunWith(SpringJUnit4ClassRunner.class) //表示繼承了SpringJUnit4ClassRunner類
@ContextConfiguration(locations = {"classpath:spring_mybatis.xml"})
public class UserTest {
private static Logger logger = Logger.getLogger(UserTest.class);
@Autowired
private IUserService userService;
@Test
public void testGetUser(){
User user = this.userService.getUserById(1);
logger.info("***************"+user.getNicke());
}
}
3、配置springMVC
一、配置spring_mvc.xml
<?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:p="http://www.springframework.org/schema/p" 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-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <!-- 自動掃描該包，使SpringMVC認爲包下用了@controller註解的類是控制器 --> <context:component-scan base-package="com.gzy.ssmTest.controller" /> <!--避免IE執行AJAX時，返回JSON出現下載文件 --> <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> </list> </property> </bean> <!-- 啓動SpringMVC的註解功能，完成請求和註解POJO的映射 --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="messageConverters"> <list> <ref bean="mappingJacksonHttpMessageConverter" /> <!-- JSON轉換器 --> </list> </property> </bean> <!-- 定義跳轉的文件的先後綴 ，視圖模式配置--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 這裏的配置個人理解是自動給後面action的方法return的字符串加上前綴和後綴，變成一個 可用的url地址 --> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> <!-- 配置文件上傳，若是沒有使用文件上傳能夠不用配置，固然若是不配，那麼配置文件中也沒必要引入上傳組件包 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 默認編碼 --> <property name="defaultEncoding" value="utf-8" /> <!-- 文件大小最大值 --> <property name="maxUploadSize" value="10485760000" /> <!-- 內存中的最大值 --> <property name="maxInMemorySize" value="40960" /> </bean> </beans>
二、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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0"> <display-name>Archetype Created Web Application</display-name> <!-- Spring和mybatis的配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring_mybatis.xml</param-value> </context-param> <!-- 編碼過濾器 --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <async-supported>true</async-supported> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- Spring監聽器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 防止Spring內存溢出監聽器 --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <!-- Spring MVC servlet --> <servlet> <servlet-name>SpringMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring_mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> <async-supported>true</async-supported> </servlet> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <!-- 此處能夠能夠配置成*.do，對應struts的後綴習慣 --> <url-pattern>/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> </web-app>
三、編寫controller
package com.gzy.ssmTest.controller;
import javax.annotation.Resource;
import org.apache.log4j.Logger;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import com.gzy.ssmTest.model.User;
import com.gzy.ssmTest.service.IUserService;
@Controller
@RequestMapping("/user")
public class UserController {
private static Logger logger = Logger.getLogger(UserController.class);
@Resource
private IUserService userService;// 用戶服務
/**
* 跳轉到登錄頁（測試）
* @param model
* @return
*/
@RequestMapping("/login")
public String loginTest(Model model){
User user = this.userService.getUserById(1);
model.addAttribute("userName", user.getNicke());
logger.info("["+user.getNicke()+" has login in seccess !!!!]");
return "index";
}
}
四、編寫頁面，index.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" isELIgnored="false"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>首頁</title>
</head>
<body>
<h1>當前登陸用戶爲：${userName }</h1>
</body>
</html>
五、在瀏覽器輸入URL，測試。http://localhost:8080/ssmTest/user/login.html
（若是以爲有用的話，‘求關注’，哈哈）
