SpringMVC-Spring-Mybatis

1.配置Spring和Mybatis

1.beans.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd">


<!-- 自动扫描 -->
<context:component-scan base-package="com.hyd" />
<context:annotation-config/>

<!-- 配置DataSource数据源 -->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/goods" />
<property name="username" value="root" />
<property name="password" value="123456" />
</bean>

<!-- 配置SqlSessionFactoryBean -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="classpath:/mybatis/mybatis.xml" />
</bean>

<!--MapperScannerConfigurer配置-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!--basePackage指定要扫描的包，在此包之下的映射器都会被
搜索到。可指定多个包，包与包之间用逗号或分号分隔-->
<property name="basePackage" value="com.hyd.mapper"/>
</bean>

</beans>

1.Spring的annotation和自动扫描包

<!-- 自动扫描 -->
<context:component-scan base-package="com.hyd" />
<context:annotation-config/>

2.配置数据源

<!-- 配置DataSource数据源 -->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/goods" />
<property name="username" value="root" />
<property name="password" value="123456" />
</bean>

3.配置SqlsessionFactoryBean

<!-- 配置SqlSessionFactoryBean --> 
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="classpath:/mybatis/mybatis.xml" />
</bean>

4.扫描Mybatis的接口映射的包

<!--MapperScannerConfigurer配置-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!--basePackage指定要扫描的包，在此包之下的映射器都会被
搜索到。可指定多个包，包与包之间用逗号或分号分隔-->
<property name="basePackage" value="com.hyd.mapper"/>
</bean>

</beans>

2.SpringMVC的配置

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-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/aop
http://www.springframework.org/schema/aop/spring-aop-3.2.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.2.xsd ">

<!-- 可以扫描controller、service、
这里让扫描controller， 制定controller的包
-->
<context:component-scan base-package="com.hyd.controller"></context:component-scan>

<!-- 静态资源解析 -->
<mvc:resources location="/js/" mapping="/js/**"/>
<mvc:resources location="/img/" mapping="/img/**"/>

<mvc:annotation-driven />

<!-- 试图解析器 ， 解析jsp， 默认使用jstl解析， classpath下的得有jstl的包
-->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>

<!-- 拦截器 -->
<mvc:interceptors>
<!-- 多个拦截器， 顺序执行 -->
<!-- 登录认证拦截七 -->
<mvc:interceptor>
<mvc:mapping path="/**"/>
<bean class="com.hyd.interceptor.LoginInterceptor"></bean>
</mvc:interceptor>
</mvc:interceptors>
</beans>

1.扫描Controller包

<!-- 可以扫描controller、service、
这里让扫描controller， 制定controller的包
-->
<context:component-scan base-package="com.hyd.controller"></context:component-scan>

2.mvc的annotation配置

<mvc:annotation-driven />

3.试图解析器

<!-- 试图解析器 ， 解析jsp， 默认使用jstl解析， classpath下的得有jstl的包
-->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>

4.拦截器

<!-- 拦截器 -->
<mvc:interceptors>
<!-- 多个拦截器， 顺序执行 -->
<!-- 登录认证拦截七 -->
<mvc:interceptor>
<mvc:mapping path="/**"/>
<bean class="com.hyd.interceptor.LoginInterceptor"></bean>
</mvc:interceptor>
</mvc:interceptors>

3.在web.xml的配置

<?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/beans.xml</param-value>
</context-param>


<!-- Spring监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</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/springMVC.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>
<!-- 此处可以可以配置成*.do，对应struts的后缀习惯 -->
<url-pattern>*.action</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>/index.jsp</welcome-file>
</welcome-file-list>
<!-- 配置SESSION超时，单位是分钟 -->
<session-config>
<session-timeout>15</session-timeout>
</session-config>

</web-app>

1.设置spring的配置文件

<!-- Spring和mybatis的配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/beans.xml</param-value>
</context-param>

2.配置spring的监听器，加载spring配置文件

<!-- Spring监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

3.配置Springmvc前端控制器

<!-- 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/springMVC.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>
<!-- 此处可以可以配置成*.do，对应struts的后缀习惯 -->
<url-pattern>*.action</url-pattern>
</servlet-mapping>
