1.                      $.ajax({  
2.     type : 'POST',  
3.     dataType : 'json',  
4.     url : getRootPath() + '/require/publish',  
5.     data : JSON.stringify(mydata),  
6.     contentType : "application/json",  
7.     success : function(data) {  
8.         alert("釋出成功！"
   );  
9.     },  
10.     error : function(data){       
11.         alert(JSON.stringify(mydata));                    
12.     }                 
13. });  

一定是漏了Jackson相關jar包，需要3個jar包，下載之後匯入：

jackson-annotations-2.6.jar

jackson-databind-2.6.jar

jackson-core-2.6.jar

同時在springmvc-servlet.xml中增加配置：

1. <!-- json轉換器 -->
2. <bean
3.     class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
4.     <propertyname="messageConverters">
5.         <list>
6.             <refbean="mappingJackson2HttpMessageConverter"/>
7.         </list>
8.     </property>
9. </bean
   >
10. <beanid="mappingJackson2HttpMessageConverter"
11.     class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
12.     <propertyname="supportedMediaTypes">
13.         <list>
14.             <value>text/html;charset=UTF-8</value>
15.             <value>text/json;charset=UTF-8</value>
16.             <value>application/json;charset=UTF-8</value>
17.         </list>
18.     </property>
19. </bean>
