Spring+SpringMVC+Mybatis整合(二)

 

目录结构:

1.导包

2.配置Spring(applicationContext.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" xmlns:p="http://www.springframework.org/schema/p"
 4     xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
 5     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 6     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
 7     http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
 8     http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
 9     http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd">
10 
11 
12     <context:property-placeholder location="classpath:db.properties"/>
13     
14     <!-- 数据库连接池 -->
15     <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
16         destroy-method="close">
17         <property name="driverClassName" value="${jdbc.driver}" />
18         <property name="url" value="${jdbc.url}" />
19         <property name="username" value="${jdbc.username}" />
20         <property name="password" value="${jdbc.password}" />
21         <property name="maxActive" value="10" />
22         <property name="maxIdle" value="5" />
23     </bean>
24     
25     <!-- Mybatis的工厂 -->
26     <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
27         <property name="dataSource" ref="dataSource"/>
28         <!-- 核心配置文件的位置 -->
29         <property name="configLocation" value="classpath:sqlMapConfig.xml"/>
30     </bean>
31 
32     <!-- Mapper动态代理开发   扫描 -->
33     <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
34         <!-- 基本包 -->
35         <property name="basePackage" value="com.itheima.springmvc.dao"/>
36     </bean>
37     
38     <!-- 注解事务 -->
39     <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
40         <property name="dataSource" ref="dataSource"/>
41     </bean>
42     
43     <!-- 开启注解 -->
44     <tx:annotation-driven transaction-manager="transactionManager"/>
45     
46     
47 </beans>

3.配置mybatis(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     <!-- 设置别名 -->
 7     <typeAliases>
 8         <!-- 2. 指定扫描包，会把包内所有的类都设置别名，别名的名称就是类名，大小写不敏感 -->
 9         <package name="com.itheima.springmvc.pojo" />
10     </typeAliases>
11 
12 </configuration>

 

4.配置SpringMVC

 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" xmlns:p="http://www.springframework.org/schema/p"
 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/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
 7         http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
 8         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">
 9 
10         
11         
12         <!-- 扫描@Controler  @Service   -->
13         <context:component-scan base-package="com.itheima"/>
14         
15         <!-- 处理器映射器 -->
16 <!--         <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/> -->
17         <!-- 处理器适配器 -->
18 <!--         <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"/> -->
19         <!-- 注解驱动 -->
20         <mvc:annotation-driven conversion-service="conversionServiceFactoryBean"/>
21         
22         <!-- 配置Conveter转换器  转换工厂 （日期、去掉前后空格）。。 -->
23         <bean id="conversionServiceFactoryBean" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
24             <!-- 配置 多个转换器-->
25             <property name="converters">
26                 <list>
27                     <bean class="com.itheima.springmvc.conversion.DateConveter"/>
28                 </list>
29             </property>
30         </bean>
31         
32         <!-- 视图解释器 -->
33         <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
34             <property name="prefix" value="/WEB-INF/jsp/"/>
35             <property name="suffix" value=".jsp"/>
36         </bean>
37         
38    </beans>

 5.web.xml配置spring监听器与springMVC前端控制器

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <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_2_5.xsd" id="WebApp_ID" version="2.5">
 3   <display-name>springmvc-mybatis</display-name>
 4   <welcome-file-list>
 5     <welcome-file>index.html</welcome-file>
 6     <welcome-file>index.htm</welcome-file>
 7     <welcome-file>index.jsp</welcome-file>
 8     <welcome-file>default.html</welcome-file>
 9     <welcome-file>default.htm</welcome-file>
10     <welcome-file>default.jsp</welcome-file>
11   </welcome-file-list>
12   
13   <context-param>
14       <param-name>contextConfigLocation</param-name>
15       <param-value>classpath:applicationContext.xml</param-value>
16   </context-param>
17   
18   <!-- Spring监听器 -->
19   <listener>
20       <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
21   </listener>
22   
23   <!-- 处理POST提交乱码问题 -->
24   <filter>
25       <filter-name>encoding</filter-name>
26       <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
27       <init-param>
28           <param-name>encoding</param-name>
29           <param-value>UTF-8</param-value>
30       </init-param>
31   </filter>
32   
33   <filter-mapping>
34       <filter-name>encoding</filter-name>
35       <url-pattern>*.action</url-pattern>
36   </filter-mapping>
37   
38   
39     <!-- 前端控制器 -->
40   <servlet>
41       <servlet-name>springmvc</servlet-name>
42       <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
43       <!-- 默认找 /WEB-INF/[servlet的名称]-servlet.xml -->
44       <init-param>
45           <param-name>contextConfigLocation</param-name>
46           <param-value>classpath:springmvc.xml</param-value>
47       </init-param>
48   </servlet>
49   
50   <servlet-mapping>
51       <servlet-name>springmvc</servlet-name>
52       <!-- 
53           1. /*  拦截所有   jsp  js png .css  真的全拦截   建议不使用
54           2. *.action *.do 拦截以do action 结尾的请求     肯定能使用   ERP  
55           3. /  拦截所有 （不包括jsp) (包含.js .png.css)  强烈建议使用     前台 面向消费者  www.jd.com/search   /对静态资源放行
56        -->
57       <url-pattern>*.action</url-pattern>
58   </servlet-mapping>
59   
60   
61 </web-app>

6.总结

配置思路:

单独配置spring>单独配置mybatis>单独配置springMVC>mybatis与spring整合>web.xml配置
