与SpringSecurity的配置类似,同样为我们提供了一个实现类WebMvcConfigurationSupport和一个注解@EnableWebMvc以帮助我们减少bean的声明。
applicationContext-MvcConfig.xml
- <!-- 启用注解,并定义组件查找规则 ,mvc层只负责扫描@Controller -->
- <context:component-scan base-package="web.function"
- use-default-filters="false">
- <context:include-filter type="annotation"
- expression="org.springframework.stereotype.Controller" />
- </context:component-scan>
- <!-- 视图处理器 -->
- <bean id="viewResolver"
- class="org.springframework.web.servlet.view.InternalResourceViewResolver">
- <property name="prefix" value="/WEB-INF/views/jsp/function/" />
- <property name="suffix" value=".jsp" />
- </bean>
- <!-- 定义国际化资源文件查找规则 ,各种messages.properties -->
- <bean id="messageSource"
- class="org.springframework.context.support.ResourceBundleMessageSource"
- p:basename="config.messages.messages">
- </bean>
- <!-- servlet适配器,这里必须明确声明,因为spring默认没有初始化该适配器 -->
- <bean id="servletHandlerAdapter"
- class="org.springframework.web.servlet.handler.SimpleServletHandlerAdapter" />
- <!-- 定义文件上传处理器 -->
- <bean id="multipartResolver"
- class="org.springframework.web.multipart.commons.CommonsMultipartResolver"
- p:defaultEncoding="UTF-8" />
- <!-- 异常处理器 -->
- <bean id="exceptionResolver" class="web.core.CP_SimpleMappingExceptionResolver">
- <property name="defaultErrorView" value="common_error" />
- <property name="exceptionAttribute" value="exception" />
- <property name="exceptionMappings">
- <props>
- <prop key="java.lang.RuntimeException">common_error</prop>
- </props>
- </property>
- </bean>
- <!-- 定义公共参数初始化拦截器 -->
- <bean id="initInterceptor" class="web.core.CP_InitializingInterceptor" />
- <!-- 本地化资源处理器 -->
- <bean id="localeResolver"
- class="org.springframework.web.servlet.i18n.CookieLocaleResolver" />
- <!-- 定义本地化变更拦截器 -->
- <bean id="localeChangeInterceptor"
- class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor" />
- <!-- 请求拦截器,每一个用户请求都会被拦截 -->
- <mvc:interceptors>
- <ref bean="localeChangeInterceptor" />
- <ref bean="initInterceptor" />
- </mvc:interceptors>
- <!-- 定义注解驱动Controller方法处理适配器 ,注:该适配器必须声明在<mvc:annotation-driven />之前,否则不能正常处理参数类型的转换 -->
- <bean
- class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
- <property name="webBindingInitializer">
- <bean class="web.core.CP_PropertyEditorRegistrar">
- <property name="format" value="yyyy-MM-dd"></property>
- </bean>
- </property>
- <property name="messageConverters">
- <list>
- <bean
- class="org.springframework.http.converter.xml.Jaxb2RootElementHttpMessageConverter" />
- <bean
- class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter" />
- </list>
- </property>
- </bean>
- <!-- 会自动注册RequestMappingHandlerMapping与RequestMappingHandlerAdapter
- 两个bean,是spring MVC为@Controllers分发请求所必须的。 并提供了:数据绑定支持,@NumberFormatannotation支持,@DateTimeFormat支持,@Valid支持,读写XML的支持(JAXB),读写JSON的支持(Jackson) -->
- <mvc:annotation-driven />
- <!-- 资源访问处理器 -->
- <mvc:resources mapping="/static/**" location="/WEB-INF/static/" />
