SpringMVC4零配置--Web上下文配置【MvcConfig】 / 憋错料

与SpringSecurity的配置类似，spring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

Xml代码

<context:component-scan base-package="web.function"
use-default-filters="false">
<context:include-filter type="annotation"
expression="org.springframework.stereotype.Controller" />
</context:component-scan>
<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>
<bean id="messageSource"
class="org.springframework.context.support.ResourceBundleMessageSource"
p:basename="config.messages.messages">
</bean>
<bean id="servletHandlerAdapter"
class="org.springframework.web.servlet.handler.SimpleServletHandlerAdapter" />
<bean id="multipartResolver"

<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>
<bean id="initInterceptor" class="web.core.CP_InitializingInterceptor" />
<bean id="localeResolver"
class="org.springframework.web.servlet.i18n.CookieLocaleResolver" />
<bean id="localeChangeInterceptor"
class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor" />
<mvc:interceptors>
<ref bean="localeChangeInterceptor" />
<ref bean="initInterceptor" />
</mvc:interceptors>
<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

<bean

</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 />
<mvc:resources mapping="/static/**" location="/WEB-INF/static/" />
