剛學習了ssm架構,ajax校正成功,分享下

1.匯入jar包

2.配置spring-servlet.xml

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

3.控制器中用@ResponseBody實現返回json資料格式

1 @ResponseBody2      @RequestMapping(value="queryByUser", method=RequestMethod.POST,produces="application/json;charset=UTF-8")  3     public User queryByName(User user,HttpServletRequest request){4         User u = userBiz.queryByName(user);5         return u;6     }

4.頁面中接收查詢到的結果

function checkUser(){          var username=$("#username").val();                    $.ajax({             url:"queryByUser",             type:"post",             data:{"username":username},             dataType:"json",            success:function(data){                 if (data!=null ) {                  $("#userSpan").text("使用者名稱已存在");                  $("#username").val(‘‘);              }else if(data==null && username !=‘‘){                  $("#userSpan").text("使用者名稱可用");              }            }          });      }

實現結果就是以下這樣的:
