spring mvc 返回json的配置

<!-- 啓動Springmvc註解驅動 -->
<mvc:annotation-driven />
<!-- 返回json 方法一 須要導入 fastjson.jar包 -->
<mvc:annotation-driven>
	<mvc:message-converters register-defaults="false">
		<!-- 避免IE執行AJAX時,返回JSON出現下載文件 -->
		<bean id="fastJsonHttpMessageConverter" class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
			<property name="supportedMediaTypes">
				<list>
					<!-- 這裏順序不能反，必定先寫text/html,否則ie下出現下載提示 -->
					<value>text/html;charset=UTF-8</value>
					<value>application/json;charset=UTF-8</value>
				</list>
			</property>
		</bean>
	</mvc:message-converters>
</mvc:annotation-driven>


<!-- 返回json 方法二 須要導入 jackson-annotations.jar,jackson-core.jar,jackson-databind.jar -->
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping" />
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
	<property name="messageConverters">
		<list>
			<bean class="org.springframework.http.converter.StringHttpMessageConverter">
				<property name="supportedMediaTypes">
					<list>
						<value>text/html; charset=UTF-8</value>
						<value>application/json;charset=UTF-8</value>
					</list>
				</property>
			</bean>
			<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
				<property name="supportedMediaTypes">
					<list>

						<value>application/json;charset=UTF-8</value>
					</list>
				</property>
			</bean>
		</list>
	</property>
</bean>


<!-- 其下與返回json 無關 -->

<!-- 自動將控制器加載到bean -->
<context:component-scan base-package="org.controller"></context:component-scan>
<!-- 配置處理靜態資源的請求 -->
<mvc:resources location="/resources/" mapping="*/res/**" />

<!-- 攔截器配置 -->
<mvc:interceptors>
	<bean class="org.aop.LoginInteceptor" />
</mvc:interceptors>

<!-- 配置視圖解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
	<property name="prefix" value="/WEB-INF/jsp/" />
	<property name="suffix" value=".jsp" /><!--可爲空,方便實現自已的依據擴展名來選擇視圖解釋類的邏輯 -->
	<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
</bean>

<!-- 上傳 須要使用到的配置 -->
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
	<property name="maxUploadSize" value="1046666000" />
</bean>

<!--配置全局的異常 -->
<bean id="exceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
	<property name="exceptionMappings">
		<props>
			<prop key="com.guanlan.util.SportException">error</prop>
		</props>
	</property>
</bean>
