SSM框架整合

1.配置Spring

　　applicationContext.xml中:

 

 1             <?xml version="1.0" encoding="UTF-8"?>
 2             <beans xmlns="http://www.springframework.org/schema/beans"

54                    </aop:config>
55 <beans>

 

2.配置SpringMVC

　　配置applicationContext-mvc.xml

 

 1             <?xml version="1.0" encoding="UTF-8"?>
 2             <beans xmlns="http://www.springframework.org/schema/beans"
 3                    xmlns:context="http://www.springframework.org/schema/context"
 4                    xmlns:mvc="http://www.springframework.org/schema/mvc"
 5                    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 6                    xsi:schemaLocation=
 7                          "http://www.springframework.org/schema/beans
 8                        http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
 9                        http://www.springframework.org/schema/context    
10                        http://www.springframework.org/schema/context/spring-context-3.2.xsd
11                        http://www.springframework.org/schema/mvc   
12                        http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">
13                   <!--开启包扫描  -->
14                   <context:component-scan base-package="cn.tedu.controller"/>
15                   <!--开启MVC注解  -->
16                   <mvc:annotation-driven/>
17                   <!--配置视图解析器  -->
18                   <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
19                           <property name="prefix" value="/WEB-INF/"></property>
20                           <property name="suffix" value=".jsp"></property>
21                   </bean>
22 </beans>

 

　　配置web.xml

 

 1             <?xml version="1.0" encoding="UTF-8"?>
 2             <web-app version="2.5" 
 3                 xmlns="http://java.sun.com/xml/ns/javaee" 
 4                 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
 5                 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
 6                 http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
 7               <display-name></display-name>    
 8               
 9               <!--配置前端控制器  -->
10               <servlet>
11                   <servlet-name>springmvc</servlet-name>
12                   <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
13                   <init-param>
14                       <param-name>contextConfigLocation</param-name>
15                       <param-value>classpath:/applicationContext*.xml</param-value>
16                   </init-param>
17               </servlet>
18               
19               <servlet-mapping>
20                   <servlet-name>springmvc</servlet-name>
21                   <url-pattern>*.action</url-pattern>
22               </servlet-mapping>
23               
24               
25               <!--中文乱码解决  -->
26               <filter>
27                   <filter-name>characterEncoding</filter-name>
28                   <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
29                   <init-param>
30                       <param-name>encoding</param-name>
31                       <param-value>utf-8</param-value>
32                   </init-param>
33               </filter>
34               
35               <filter-mapping>
36                   <filter-name>characterEncoding</filter-name>
37                   <url-pattern>/*</url-pattern>
38               </filter-mapping>
39               
40               
41               <welcome-file-list>
42                 <welcome-file>index.jsp</welcome-file>
43               </welcome-file-list>
44 </web-app>

 

3.配置Mybatis

　　配置sqlMapConfig,xml

 

1             <?xml version="1.0" encoding="UTF-8" ?>
2             <!DOCTYPE configuration
3             PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
4             "http://mybatis.org/dtd/mybatis-3-config.dtd">
5             <configuration>
6                 <!--添加缓存  引入第三方二级缓存 -->
7             
8 </configuration>

 

　　配置applicationContext.xml

 

 1             <!--整合Mybaits  -->
 2              <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
 3                        <!--引入数据源  -->
 4                        <property name="dataSource" ref="dataSource"></property>
 5                            
 6                        <!--引入核心配置文件  -->
 7                        <property name="configLocation" value="classpath:/sqlMapConfig.xml"/>
 8                            
 9                        <!--引入映射文件  -->
10                        <property name="mapperLocations" value="classpath:/cn/tedu/pojo/*.xml"/>
11    </bean>

 

　　创建bean,并同时创建bean的映射文件:

 

 1             User类：
 2                 public class User {
 3                     private Integer id;
 4                     private String name;
 5                     private Integer age;
 6                     private String sex;
 7                     …
 8                 }
 9             UserMapper.xml
10                 <?xml version="1.0" encoding="UTF-8" ?>
11                 <!DOCTYPE mapper
12                 PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
13                 "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
14                 <mapper namespace="cn.tedu.mapper.UserMapper">
15                 
16                     
17                     <select id="findAll" resultType="cn.tedu.pojo.User">
18                         select * from user
19                     </select>
20                     <select id="findOne" resultType="cn.tedu.pojo.User">
21                         select * from user where id = #{id}
22                     </select>
23                     
24                     
25 </mapper>

 

　　创建bean的mapper接口:

 

 1             package cn.tedu.mapper;
 2             
 3             import java.util.List;
 4             
 5             import cn.tedu.pojo.User;
 6             
 7             public interface UserMapper {
 8                 public List<User> findAll();
 9                 public List<User> findOne(int id);
10 }

 

　　为了能让Mybatis扫描识别bean的Mapper类,需要在Spring再注册一个扫描器bean,扫描指定包:

在applicationContext.xml中:
