SpringMVC使用JSON傳遞數據

1.jar包支持: jackson-all-1.9.8.jar.

2.spring-mvc-servlet.xml中加入以下驅動

    <mvc:annotation-driven>
   <mvc:message-converters>
      <bean  class="org.springframework.http.converter.StringHttpMessageConverter">
        <property name="supportedMediaTypes">
           <list>
             <value>text/html;charset=UTF-8</value>
           </list>
        </property>    
      </bean>
   </mvc:message-converters>

</mvc:annotation-driven>

3. 測試

        @RequestMapping("/testJson")
@ResponseBody
public Map<String, String> testJson(){
Map<String, String> map = new HashMap<String, String>();
map.put("id", "001");
map.put("name", "tom");
return map;
}
