1 web.xml

1.1前端控制器

<!-- 配置Spring MVC前端核心控制器 -->
<servlet>
  <servlet-name>springmvc</servlet-name>
  <servlet-class>
      org.springframework.web.servlet.DispatcherServlet
  </servlet-class>
      <!-- 需要配置springmvc-config.xml文件 -->
  <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springmvc-config.xml</param-value>
  </init-param>
  <!-- 配置服务器启动后立即加载Spring MVC配置文件 -->
  <load-on-startup>1</load-on-startup>
</servlet>
<!--对上述配置文件进行映射配置-->
<servlet-mapping>
  <servlet-name>springmvc</servlet-name>
  <url-pattern>*.action</url-pattern>
</servlet-mapping>

ps: classpath是WEB-INF下的classes文件路径，在工程项目下新建config,内部的文件会自动加载到classes文件下，需要在navigator视图下才能看得到。（这是在.clsspath配置里设置的）

1.2配置编码过滤器

    <!-- 配置编码过滤器 -->
    <filter>
        <filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

1.3事物传播行为以及切面配置

<!-- 通知 -->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <!-- 传播行为 -->
            <tx:method name="save*" propagation="REQUIRED" />
            <tx:method name="insert*" propagation="REQUIRED" />
            <tx:method name="add*" propagation="REQUIRED" />
            <tx:method name="create*" propagation="REQUIRED" />
            <tx:method name="delete*" propagation="REQUIRED" />
            <tx:method name="update*" propagation="REQUIRED" />
            <tx:method name="find*" propagation="SUPPORTS" 
                                           read-only="true" />
            <tx:method name="select*" propagation="SUPPORTS" 
                                           read-only="true" />
            <tx:method name="get*" propagation="SUPPORTS" 
                                           read-only="true" />
        </tx:attributes>
    </tx:advice>
    
    <!-- 切面 -->
    <aop:config>
        <aop:advisor advice-ref="txAdvice"
             pointcut="execution(* com.simple.core.service.*.*(..))" />
    </aop:config>

2.springmvc-config.xml

2.1 配置控制器扫描

    <!-- 我的扫描包是com.simple.core.web.controller -->
    <context:component-scan base-package="com.simple.core.web.controller" />

2.2配置视图控制器

    <!-- 配置视图解释器ViewResolver 主要是对前后缀的配置 -->
    <bean id="jspViewResolver" class=
    "org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>

2.3配置自定义类型转换器

    <!-- 显示的装配自定义类型转换器 --> 
    <mvc:annotation-driven conversion-service="conversionService" />
    <!-- 自定义类型转换器配置 -->
    <bean id="conversionService" class=
     "org.springframework.context.support.ConversionServiceFactoryBean">
        <property name="converters">
            <set>
                <bean class="com.simple.convert.DateConverter" />
            </set>
        </property>
    </bean>

2.4配置注解驱动

<!-- 配置注解驱动 -->
<mvc:annotation-driven />

配置了扫描就不需要配置主注解驱动了原因如下

1><mvc:annotation-driven/>会自动注册DefaultAnnotationHandlerMapping与AnnotationMethodHandlerAdapter 两个bean
        DefaultAnnotationHandlerMapping ：负责扫描带有@Controller注解的类，给此类设置对应的@RequestMapping
        AnnotationMethodHandlerAdapter ：负责扫描Controller类中的方法，给方法设置对应的@RequestMapping
2><context:component-scan base-package=""></context:component-scan>
        扫描器会扫描带有@Component@Service@Controller@Component等注解，并实现相应的操作，
        因为这四个注解包含了@Controller，
        所以会将Controller类和方法进行映射，不需要用<mvc:annotation-driven/>了

2.5配置静态资源访问映射

<!--配置静态资源的访问映射，此配置中的文件，将不被前端控制器拦截 -->
       <!--方法1-->
     <mvc:resources location="/js/" mapping="/js/**" />
       <!--方法2-->
      <servlet-mapping>
      <servlet-name>default</servlet-name>
      <url-pattern>*.jpg</url-pattern>
      </servlet-mapping>
         <!--方法3-->
      <mvc:default-servlet-handler/>
    <!--方法1和2可以自定义拦截类型，但方法2效率更高，方法1常用，方法三不可自定义拦截-->

2.6配置拦截器

拦截器配置

<!-- 配置拦截器 -->
    <mvc:interceptors>
       <!--使用bean直接定义在<mvc:interceptors>下面的拦截器将拦截所有请求-->
      <!--  <bean class="com.simple.interceptor.CustomInterceptor"/> -->    
       <!-- 拦截器1 -->
        <mvc:interceptor>
            <!-- 配置拦截器作用的路径 -->
            <mvc:mapping path="/**" />
            <!-- 定义在<mvc:interceptor>下面的表示匹配指定路径的请求才进行拦截的 -->
            <bean class="com.simple.interceptor.Interceptor1" />
        </mvc:interceptor>
        <!-- 拦截器2 -->
        <mvc:interceptor>
            <mvc:mapping path="/hello" />
            <bean class="com.simple.interceptor.Interceptor2" />
        </mvc:interceptor>

拦截器代码:ps:需要继承HandlerInterceptor接口，并实现三个方法

public class Interceptor1 implements HandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest request, 
        HttpServletResponse response, Object handler) throws Exception {
        System.out.println("Intercepter1...preHandle");
        return true;
    }
    @Override
    public void postHandle(HttpServletRequest request, 
        HttpServletResponse response, Object handler,
        ModelAndView modelAndView) throws Exception {
        System.out.println("Intercepter1...postHandle");
    }
    @Override
    public void afterCompletion(HttpServletRequest request, 
        HttpServletResponse response, Object handler, 
        Exception ex) throws Exception {
        System.out.println("Intercepter1...afterCompletion");
    }
}
<!--
输出
Intercepter1...preHandle
Interceptor2...preHandle
Intercepter2...afterCompletion
Intercepter1...afterCompletion
-->

2.7配置文件上传解析器

    <!-- 配置文件上传解析器 MultipartResolver -->
    <bean id="multipartResolver" class=
   "org.springframework.web.multipart.commons.CommonsMultipartResolver">
          <!-- 设置请求编码格式-->
          <property name="defaultEncoding" value="UTF-8" />
    </bean>
