<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver"> 
    <property name="mediaTypes"> 
     <map> 
      <entry key="atom" value="application/atom+xml" /> 
      <entry key="html" value="text/html" /> 
      <entry key="json" value="application/json" /> 
     </map>

<mvc:annotation-driven /> 

<context:annotation-config /> 

<context:component-scan base-package="org.lxh"></context:component-scan> 

và đang là:

@RequestMapping(value = "/2wt/test.do",method=RequestMethod.POST) 
public @ResponseBody 
Map<String, ? extends Object> create(
     @RequestBody WtStandartype wtStandartype) { 
    System.out.println(wtStandartype.getId() + "--------"); 
    return Collections.singletonMap("id", wtStandartype.getId()); 

} 

javascript là:

jQuery.ajax({ 
       'type': 'POST', 
       'url': '/2wt/test.do',//'WtStandardTypeList.do?addto=updb', 
       'contentType': 'application/json', 
       'data': JSON.stringify(jsonuserinfo), 
       'dataType': 'json', 
       'error':function(){ 
        alert(222); 
       }, 
       'success': function(){ 
        alert(33333); 
       } 
      });

Tại sao bạn không gửi thành công?

Answer 1

Ứng dụng Spring mẫu mvc-showcase mẫu có trình biến đổi tin nhắn đọc json và xml vào màn hình với yêu cầu JQuery cho Ajax, bạn có thể thử và sử dụng ví dụ đó để lập mô hình mã của bạn.
