pring相關概念及SSM框架在本文當中就不多述了，直接上乾貨！

一、用myEclipse初始化Web項目

       新建一個web project:


二、創建包

controller        //控制類

service//服務接口
service.impl//服務實現類
dao  //data access object(接口）
dao.impl  //實現類

domain  //實體類

mappers  //mybatis的配置映射文件
        util             //工具類

         

三、是maven方式引入類庫

3.1啓動tomcat服務

3.2給web項目添加maven支持（引入maven私服庫）

   將web項目轉化爲maven項目：


3.3引入依賴

spring

mybatis
spring mvc
c3p0類庫
mysql

.......

3.4主要是編寫pom.xml文件

[html]  view plain  copy

  145. </project>  

四、創建dao和service的基礎類庫

UserDao.java如下：

[java]  view plain  copy
  1. package com.liuhai.eshop.dao;  
  2.   
  3. import java.util.List;  
  4. import java.util.Map;  
  5.   
  6. import com.liuhai.eshop.domain.User;  
  7. /** 
  8.  * 用戶DAO接口 
  9.  * @author Administrator 
  10.  * 
  11.  */  
  12. public interface UserDao {  
  13.     /** 
  14.      * 用戶登錄 
  15.      * @param user 
  16.      * @return 
  17.      */  
  18.     public User login(User user);  
  19.     /** 
  20.      * 查詢所有用戶 
  21.      * @return 
  22.      */  
  23.     public List<User> getAll();  
  24.     /** 
  25.      * 根據條件查詢用戶 
  26.      * @param user 
  27.      * @return 
  28.      */  
  29.     public User getUser(User user);  
  30.     /** 
  31.      * 刪除用戶 
  32.      * @param user 
  33.      * @return 
  34.      */  
  35.     public int delete(int id);  
  36.     /** 
  37.      * 更新用戶 
  38.      * @param user 
  39.      * @return 
  40.      */  
  41.     public int update(User user);  
  42.     /** 
  43.      * 添加用戶 
  44.      * @param user 
  45.      * @return 
  46.      */  
  47.     public int add(User user);  
  48.     /** 
  49.      * 用戶查詢 
  50.      * @param map 
  51.      * @return 
  52.      */  
  53.     public List<User> find(Map<String,Object> map);  
  54.     /** 
  55.      * 獲取總記錄數 
  56.      * @param map 
  57.      * @return 
  58.      */  
  59.     public Long getTotal(Map<String,Object> map);  
  60.     /** 
  61.      * 根據id查詢用戶 
  62.      * @param id 
  63.      * @return 
  64.      */  
  65.     public User getUserById(int id);  
  66. }  

UserService.java 用戶service層接口如下：

[java]  view plain  copy
  1. package com.liuhai.eshop.service;  
  2.   
  3. import java.util.List;  
  4. import java.util.Map;  
  5. import com.liuhai.eshop.domain.User;  
  6.   
  7. public interface UserService {  
  8.       public List<User> getAll();  
  9.       public User getUser(User user);  
  10.       public int delete(int id);  
  11.       public int update(User user);  
  12.       public int add(User user);  
  13.       public List<User> find(Map<String,Object> map);  
  14.       public Long getTotal(Map<String,Object> map);  
  15.       public User getUserById(int id);  
  16. }  

UserServiceImpl.java 用戶service實現層如下：

[java]  view plain  copy
  1. package com.liuhai.eshop.service.impl;  
  2.   
  3. import java.util.List;  
  4. import java.util.Map;  
  5.   
  6. import javax.annotation.Resource;  
  7.   
  8. import org.springframework.stereotype.Service;  
  9.   
  10. import com.liuhai.eshop.dao.UserDao;  
  11. import com.liuhai.eshop.domain.User;  
  12. import com.liuhai.eshop.service.UserService;  
  13. @Service(value="userService")  
  14. public class UserServiceImpl implements UserService {  
  15.     private UserDao userDao;  
  16.     @Resource  
  17.     public void setUserDao(UserDao userDao) {  
  18.         this.userDao = userDao;  
  19.     }  
  20.     @Override  
  21.     public List<User> getAll() {  
  22.         return userDao.getAll();  
  23.     }  
  24.   
  25.     @Override  
  26.     public User getUser(User user) {  
  27.            return userDao.getUser(user);  
  28.     }  
  29.   
  30.     @Override  
  31.     public int delete(int id) {  
  32.         return userDao.delete(id);  
  33.     }  
  34.   
  35.     @Override  
  36.     public int update(User user) {  
  37.          return userDao.update(user);  
  38.     }  
  39.   
  40.     @Override  
  41.     public int add(User user) {  
  42.           return userDao.add(user);  
  43.     }  
  44.   
  45.     @Override  
  46.     public List<User> find(Map<String, Object> map) {  
  47.          return userDao.find(map);  
  48.     }  
  49.   
  50.     @Override  
  51.     public Long getTotal(Map<String, Object> map) {  
  52.          return userDao.getTotal(map);  
  53.     }  
  54.     public User getUserById(int id){  
  55.         return userDao.getUserById(id);  
  56.     }  
  57. }  

user實體類如下：

[java]  view plain  copy
  1. package com.liuhai.eshop.domain;  
  2.   
  3. import java.io.Serializable;  
  4.   
  5. /** 
  6.  * 用戶實體 
  7.  * @author Administrator 
  8.  * 
  9.  */  
  10. public class User implements Serializable{  
  11.     private static final long serialVersionUID = 1L;  
  12.     private Integer id;  
  13.     private String userName;  
  14.     private String password;  
  15.     private Integer age;  
  16.     private String trueName;  
  17.     private String email;  
  18.     private String phone;  
  19.     private String roleName;  
  20.     public Integer getId() {  
  21.         return id;  
  22.     }  
  23.     public void setId(Integer id) {  
  24.         this.id = id;  
  25.     }  
  26.   
  27.     public Integer getAge() {  
  28.         return age;  
  29.     }  
  30.     public void setAge(Integer age) {  
  31.         this.age = age;  
  32.     }  
  33.     public String getPassword() {  
  34.         return password;  
  35.     }  
  36.     public void setPassword(String password) {  
  37.         this.password = password;  
  38.     }  
  39.     public String getUserName() {  
  40.         return userName;  
  41.     }  
  42.     public void setUserName(String userName) {  
  43.         this.userName = userName;  
  44.     }  
  45.     public String getTrueName() {  
  46.         return trueName;  
  47.     }  
  48.     public void setTrueName(String trueName) {  
  49.         this.trueName = trueName;  
  50.     }  
  51.     public String getEmail() {  
  52.         return email;  
  53.     }  
  54.     public void setEmail(String email) {  
  55.         this.email = email;  
  56.     }  
  57.     public String getPhone() {  
  58.         return phone;  
  59.     }  
  60.     public void setPhone(String phone) {  
  61.         this.phone = phone;  
  62.     }  
  63.     public String getRoleName() {  
  64.         return roleName;  
  65.     }  
  66. <h1><a name="t8"></a>   public void setRoleName(String roleName) {</h1>     this.roleName = roleName;  
  67.     }  
  68. }  

五、配置spring配置文件、jdbc和日誌屬性文件、myBatis的mapper.xml文件

     5.1  spring配置文件applicationContext.xml如下：

[html]  view plain  copy
  1. <?xml version="1.0" encoding="UTF-8"?>  
  2. <beans xmlns="http://www.springframework.org/schema/beans"  
  3.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
  4.     xmlns:aop="http://www.springframework.org/schema/aop"  
  5.     xmlns:context="http://www.springframework.org/schema/context"  
  6.     xmlns:tx="http://www.springframework.org/schema/tx"  
  7.     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd  
  8.         http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd  
  9.         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd  
  10.         http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">  
  11.     <!-- 屬性配置文件 -->  
  12.     <context:property-placeholder location="classpath:jdbc.properties"/>  
  13.     <!-- 組件掃描，指定spring管理哪些bean -->  
  14.     <context:component-scan base-package="com.liuhai.eshop.dao.impl,com.liuhai.eshop.service.impl"></context:component-scan>  
  15.       
  16.     <!-- 註解驅動 -->  
  17.     <tx:annotation-driven/>  
  18.     <!-- 創建數據源 -->  
  19.     <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">  
  20.         <property name="driverClass" value="${jdbc.driverclass}"></property>  
  21.         <property name="jdbcUrl" value="${jdbc.url}"></property>  
  22.         <property name="user" value="${jdbc.username}"></property>  
  23.         <property name="password" value="${jdbc.password}"></property>  
  24.         <property name="initialPoolSize" value="${c3p0.pool.size.init}"></property>  
  25.         <property name="minPoolSize" value="${c3p0.pool.size.min}"></property>  
  26.         <property name="maxPoolSize" value="${c3p0.pool.size.max}"></property>  
  27.         <property name="acquireIncrement" value="${c3p0.pool.size.increment}"></property>  
  28.     </bean>  
  29.     <!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 -->    
  30.     <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">    
  31.         <property name="dataSource" ref="dataSource" />    
  32.         <!-- 自動掃描mapping.xml文件 -->    
  33.         <property name="mapperLocations" value="classpath:com/liuhai/eshop/mappers/*.xml"></property>    
  34.     </bean>   
  35.     <!-- DAO接口所在包名，Spring會自動查找其下的類 -->    
  36.     <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">  
  37.         <property name="basePackage" value="com.liuhai.eshop.dao"></property>  
  38.         <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>  
  39.     </bean>  
  40.     <!-- 事務管理器，service層面上實現事務管理的 -->  
  41.     <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">  
  42.         <property name="dataSource" ref="dataSource"></property>  
  43.     </bean>  
  44. </beans>  

5.2 jdbc屬性文件jdbc.properties如下：

[html]  view plain  copy
  1. jdbc.driverclass=com.mysql.jdbc.Driver  
  2. jdbc.url=jdbc\:mysql\://localhost\:3306/eshop  
  3. jdbc.username=root  
  4. jdbc.password=123456  
  5. c3p0.pool.size.max=10  
  6. c3p0.pool.size.min=2  
  7. c3p0.pool.size.init=3  
  8. c3p0.pool.size.increment=2  
  9.   
  10. hibernate.dialect=org.hibernate.dialect.MySQL5Dialect  
  11. hibernate.show_sql=true  
  12. hibernate.hbm2ddl.auto=none  

5.3 日誌屬性文件log4j.properties如下：

[html]  view plain  copy
  1. log4j.rootLogger=INFO,Console,File    
  2. #定義日誌輸出目的地爲控制檯    
  3. log4j.appender.Console=org.apache.log4j.ConsoleAppender    
  4. log4j.appender.Console.Target=System.out    
  5. #可以靈活地指定日誌輸出格式，下面一行是指定具體的格式    
  6. log4j.appender.Console.layout = org.apache.log4j.PatternLayout    
  7. log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n

5.4 myBatis的mapper.xml文件（UserMapper.xml）

  61.     </update>  
  62. </mapper>  

六、創建測試類，測試數據源是否通了

    以上spring框架及spring+mybatis配置基本完成，再就是創建測試類測試數據源是否通

 首先創建一個mysql庫的，再建立users表，創建測試類TestSpring.java如下：

   

[java]  view plain  copy
  1. package com.liuhai.eshop;  
  2.   
  3. import org.junit.Test;  
  4. import org.springframework.context.ApplicationContext;  
  5. import org.springframework.context.support.ClassPathXmlApplicationContext;  
  6.   
  7. import com.liuhai.eshop.domain.User;  
  8. import com.liuhai.eshop.service.UserService;  
  9.   
  10. public class TestSpring {  
  11.     @Test  
  12.     public void TestUserService() throws Exception{  
  13.         @SuppressWarnings("resource")  
  14.         ApplicationContext ac=new ClassPathXmlApplicationContext("applicationContext.xml");  
  15.         UserService us=(UserService) ac.getBean("userService");  
  16.         User user=new User();  
  17.         user.setAge(1);  
  18.         user.setUserName("zhangsan");  
  19.         user.setPassword("123456");  
  20.         user.setTrueName("張三");  
  21.         us.add(user);  
  22.     }  
  23. }  
最後查詢users表中是否有新插入的數據。

七、整合SpringMVC

7.1、配置spring-mvc.xml

配置裏面的註釋也很詳細，在此就不說了，主要是自動掃描控制器，視圖模式，註解的啓動這三個

[html]  view plain  copy
  1. <span style="font-size:18px;"><?xml version="1.0" encoding="UTF-8"?>  
  2. <beans xmlns="http://www.springframework.org/schema/beans"  
  3.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
  4.     xmlns:context="http://www.springframework.org/schema/context"  
  5.     xmlns:mvc="http://www.springframework.org/schema/mvc"  
  6.     xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd  
  7.         http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd  
  8.         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">  
  9.       
  10.     <!-- 自動掃描該包，使SpringMVC認爲包下用了@controller註解的類是控制器 -->    
  11.     <context:component-scan base-package="com.liuhai.eshop.controller"></context:component-scan>  
  12.     <!--避免IE執行AJAX時，返回JSON出現下載文件 -->    
  13.     <bean id="mappingJacksonHttpMessageConverter"    
  14.         class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">    
  15.         <property name="supportedMediaTypes">    
  16.             <list>    
  17.                 <value>text/html;charset=UTF-8</value>    
  18.             </list>    
  19.         </property>    
  20.     </bean>    
  21.     <!-- 啓動SpringMVC的註解功能，完成請求和註解POJO的映射 -->   
  22.     <!-- 詳細介紹：http://www.ibm.com/developerworks/cn/web/wa-restful/ -->   
  23.     <bean    
  24.         class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">    
  25.         <property name="messageConverters">    
  26.             <list>    
  27.                 <ref bean="mappingJacksonHttpMessageConverter" /> <!-- 對象轉化爲JSON轉換器 -->    
  28.             </list>    
  29.         </property>    
  30.     </bean>    
  31.     <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
  32.         <property name="prefix" value="/jsps/"></property>  
  33.         <property name="suffix" value=".jsp"></property>  
  34.     </bean>  
  35.     <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">  
  36.         <!-- 默認編碼 -->   
  37.         <property name="defaultEncoding" value="utf-8"></property>  
  38.         <!-- 文件大小最大值 -->    
  39.         <property name="maxUploadSize" value="10485760000"></property>  
  40.         <!-- 內存中的最大值 -->    
  41.         <property name="maxInMemorySize" value="40960"></property>  
  42.     </bean>  
  43. </beans></span>  

7.2、配置web.xml文件

         這裏面對applicationContext.xml的引入以及配置的spring-mvc的Servlet就是爲了完成SSM整合，之前2框架整合不需要在此處進行任何配置。配置一樣有詳細註釋，不多解釋了。

[html]  view plain  copy
  1. <?xml version="1.0" encoding="UTF-8"?>  
  2. <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

7.3 新建控制類controller及jsp頁面之間交互

    在這裏使用jsp頁面引入easyui集成並實現增刪改查功能

userManage.jsp如下：

[html]  view plain  copy
  1. <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
