SSM图书管理（二）

本篇文章主要讲述SSM框架搭建需要进行的相关配置。
（1）web.xml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"> 

  <!-- 解决SSM前台提交数据到后台乱码问题 -->
  <filter>
     <filter-name>CharacterEncoding</filter-name>
     <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
     <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
     </init-param>
  </filter>
  <filter-mapping>
     <filter-name>CharacterEncoding</filter-name>
     <url-pattern>/*</url-pattern>
  </filter-mapping>

  <!-- spring配置 -->
  <context-param><!-- 全局范围内环境参数初始化 -->
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>

  <listener>        <!--用来设定Listener接口-->  
   <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class><!--定义Listener的类名称-->  
  </listener>  

  <!-- spring mvc核心：分发servlet -->
  <servlet>
    <servlet-name>mvc-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- spring mvc的配置文件 -->
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:springMVC.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>mvc-dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
</web-app>

（2）applicationContext.xml配置

<?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:aop="http://www.springframework.org/schema/aop"

    xmlns:jdbc="http://www.springframework.org/schema/jdbc"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="

     http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd

     http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">

     <!-- 1.通过注解，将service的生命周期纳入spring框架进行管理 -->
     <context:annotation-config/>
     <context:component-scan base-package="service"></context:component-scan>
     <!-- 2.配置数据源 -->
     <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">  
      <property name="driverClassName">  
          <!-- 加载驱动程序 -->
          <value>com.mysql.jdbc.Driver</value>  
      </property>  
      <property name="url">  
          <value>jdbc:mysql://localhost:3306/15ssm?characterEncoding=UTF-8</value>  
      </property>  
      <property name="username">  
          <value>root</value>  
      </property>  
      <property name="password">  
          <value>cheng</value>  
      </property>   
    </bean>

    <!-- 3.扫描存放sql语句的Book.xml -->
    <!-- mybatis登场 -->
    <bean id="sqlSession" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="typeAliasesPackage" value="pojo" /><!-- Book.java的包名 -->
        <property name="dataSource" ref="dataSource"/><!-- 连接数据库 -->
        <property name="mapperLocations" value="classpath:mapper/*.xml"/>
    </bean>

    <!-- 4.扫描Mapper,并将其生命周期纳入spring管理 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="mapper"></property> 
    </bean>
</beans>

（3）springMVC.xml配置

<?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:aop="http://www.springframework.org/schema/aop"

        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd 
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">

    <!-- 1.扫描control,并将其纳入spring管理 -->
    <context:annotation-config/>

    <context:component-scan base-package="control"><!-- 控制层的包名 -->
          <context:include-filter type="annotation" 
          expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!-- 2.注解驱动，使得访问路径和方法的匹配可以通过注解来进行配置 -->
    <mvc:annotation-driven />
    <!-- 3.静态页面的跳转 -->
    <mvc:default-servlet-handler />

    <!-- 视图定位/WebContent/curp -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/curp/" />
