    配置方法一

    **1、导入第三方的jackson包,jackson-mapper-asl-1.9.7.jar和jackson-core-asl-1.9.7.jar。  2、spring配置文件添加**

    <mvc:annotation-driven/> <!-- 避免IE执行AJAX时,返回JSON出现下载文件 --> <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> </list> </property> </bean> <!-- 启动Spring MVC的注解功能,完成请求和注解POJO的映射 --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="messageConverters"> <list> <ref bean="mappingJacksonHttpMessageConverter" /><!-- json转换器 --> </list> </property> </bean> 12345678910111213141516171819 12345678910111213141516171819

    配置方案二(常用)

    **1、导入第三方的fastjson包,fastjson-1.1.34.jar  2、Spring配置文件添加:**

    <mvc:annotation-driven> <mvc:message-converters register-defaults="true"> <!-- 避免IE执行AJAX时,返回JSON出现下载文件 --> <bean id="fastJsonHttpMessageConverter" class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>application/json;charset=UTF-8</value> </list> </property> </bean> </mvc:message-converters> </mvc:annotation-driven> 123456789101112 123456789101112

    配置方案三

    * 1、需要导入 jackson-annotations-*.jar,jackson-core-.jar,jackson-databind-.jar  2、在spring中添加配置**

    <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>text/html; charset=UTF-8</value> <value>application/json;charset=UTF-8</value> </list> </property> </bean> </list> </property> </bean> 1234567891011121314151617181920212223 1234567891011121314151617181920212223 下载地址:http://download.csdn.net/detail/l3922768721/9543001
