Spring MVC整理系列(02)————Spring MVC配置解析及整合Spring IOC

1、在Web.xml中配置SpringMVC

<!-- Spring主容器配置，加载ApplicationContext容器，如果整合mybatis，此文件包含mybaits配置 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-context.xml</param-value> </context-param> <!-- Spring监听器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!--Spring MVC Servlet配置，加载WebApplicationContext容器 --> <servlet> <servlet-name>springServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springServlet</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> <!-- 编码过滤器 --> <filter> <filter-name>encodingFilter</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> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>

2、spring-mvc.xml配置

<!-- 加载配置属性文件--> <context:property-placeholder ignore-unresolvable="true" location="classpath:config.properties" /> <!-- 使用Annotation自动注册Bean,只扫描@Controller --> <context:component-scan base-package="com.test.springmvc" use-default-filters="false"><!-- base-package 如果多个，用“,”分隔 --> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!-- HandlerMapping无需配置，Spring MVC默认自动注册DefaultAnnotationHandlerMapping的annotation-driven的HandlerMapping和AnnotationMethodHandlerAdapter --> <!-- 配置扩充注解驱动，将请求参数绑定到控制器参数上 --> <mvc:annotation-driven /> <!-- REST中根据URL后缀自动判定Content-Type及相应的View --> <bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean"> <property name="mediaTypes" > <map> <entry key="xml" value="application/xml"/> <entry key="json" value="application/json"/> </map> </property> <property name="ignoreAcceptHeader" value="false"/> <property name="favorPathExtension" value="false"/> </bean> <!-- 对静态资源文件的访问，避免使用DefaultAnnoationHandlerMapping 和 AnnotationMethodHandlerAdapter处理mapping到Controller的path --> <mvc:default-servlet-handler /> <!-- 静态资源映射 --> <mvc:resources mapping="/static/**" location="/static/" cache-period="31536000"/> <!-- 定义视图文件解析 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/"/> <property name="suffix" value=".jsp"/> </bean> <!-- 配置文件上传，如果没有使用文件上传可以不用配置，当然如果不配，那么配置文件中也不必引入上传组件包 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 默认编码 --> <property name="defaultEncoding" value="utf-8" /> <!-- 文件大小最大值 --> <property name="maxUploadSize" value="10485760000" /> <!-- 内存中的最大值 --> <property name="maxInMemorySize" value="40960" /> </bean> <!-- 异常处理 --> <bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver"> <!-- 定义默认的异常处理页面，当该异常类型的注册时使用 --> <property name="defaultErrorView" value="error"></property> <!-- 定义异常处理页面用来获取异常信息的变量名，默认名为exception --> <property name="exceptionAttribute" value="ex"></property> <!-- 定义需要特殊处理的异常，比如自定义异常，用类名或完全路径名作为key，异常页名作为值 --> <property name="exceptionMappings"> <props> <prop key="com.test.springmvc.Interceptor.MyException">/error/403</prop> </props> </property> </bean> <!-- 自定义拦截器interceptor setting --> <mvc:interceptors> <mvc:interceptor> <mvc:mapping path="/mvc/**"/> <mvc:exclude-mapping path="/static/**"/> <bean class="com.test.springmvc.Interceptor.MyInterceptor"></bean> </mvc:interceptor> </mvc:interceptors>

自定义的异常处理类：

public class MyException extends RuntimeException { private static final long serialVersionUID = 1L; /** 错误Key，用于唯一标识错误类型 */ private String errorCode = null; /** * 构造函数 */ public MyException() { } /** * 构造函数 * @param errorCode 异常编码 */ public MyException(String errorCode) { this.errorCode = errorCode; } /** * 重载构造函数 */ public MyException(String errorCode, String errorMessage) { super(errorMessage); this.errorCode = errorCode; } /** * 异常编码 * @return String */ public String getErrorCode() { return this.errorCode; } }

自定义的拦截器：

public class MyInterceptor implements HandlerInterceptor { @Override public void afterCompletion(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, Exception arg3) throws Exception { System.out.println("afterCompletion"); } @Override public void postHandle(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2, ModelAndView arg3) throws Exception { System.out.println("postHandle"); } @Override public boolean preHandle(HttpServletRequest arg0, HttpServletResponse arg1, Object arg2) throws Exception { System.out.println("preHandle"); return true; } }

3、整合SpringIOC和SpringMVC，配置spring主容器spring-context.xml

<?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:context="http://www.springframework.org/schema/context" xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:util="http://www.springframework.org/schema/util" xmlns:task="http://www.springframework.org/schema/task" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-4.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.0.xsd" default-lazy-init="false"> <!-- 加载配置属性文件 --> <context:property-placeholder ignore-unresolvable="true" location="classpath:config.properties" /> <!-- 使用Annotation自动注册Bean，解决事物失效问题：在主容器中不扫描@Controller注解，在SpringMvc中只扫描@Controller注解。 --> <context:component-scan base-package="com.mdf.sc,com.mdf.sentry"><!-- base-package 如果多个，用“,”分隔 --> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!-- MyBatis begin --> <!-- MyBatis end --> </beans>
