I am trying to Post data from ajax to Spring Controller but not able to Bind the data to the @ModelAttribute.I am using Spring version 4.3.3. I have been trying different methods, which ended up in Errors 400,405,406,415.I have given the codes below.Please do help as i stuck up with this.
Spring Controller
@ResponseBody
@RequestMapping(value="{urls}/design", method=RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
public String getDesign(@PathVariable("urls") String urls, @ModelAttribute JsonExample jsonExample ){
System.out.println(jsonExample);
return jsonExample.getName();
}
Ajax Post
var url = $("#crumblink").attr("href");
var token = $('#csrfToken').val();
var header = $('#csrfHeader').val();
var data = {name:"Abc"};
$.ajax({
type : 'POST',
contentType : "application/json",
url : url + '/design',
data: JSON.stringify(data),
dataType : 'json',
beforeSend: function(xhr) {
xhr.setRequestHeader(header, token);
},
success : function(data) {
console.log("SUCCESS: ", data);
},
error : function(e) {
console.log("ERROR: ", e);
}
});
JsonExample模型类
public class JsonExample {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Override
public String toString() {
return "JsonExample [name=" + name + "]";
}
}

当我提交详细信息时，我得到的只是
And when I submit the details all I get is
XML Parsing Error: no element found Location: moz-nullprincipal:{2269913a-adbb-43e8-bf5a-d2d9586f35f7} Line Number 1, Column 1:
^
因为我发送的数据未与控制器中指定的@ModelAttribute绑定.
because the data I sent does not bind with the @ModelAttribute specified in the controller.
推荐答案
由于传入数据为JSON格式，因此不能使用 @ModelAttribute 绑定到Java对象.您必须先转换这些数据，然后再将其绑定到模型.Spring提供了一种使用 @RequestBody 注释的简单方法.
As your incoming data are in JSON format, you can't use @ModelAttribute for binding to a Java object. You have to convert these data before binding them to your model. Spring offers a simple way to do that, using @RequestBodyannotation.
@RequestBody 隐式使用消息转换器来转换您的数据，如果您在类路径中具有JSON数据绑定jar，Spring会自动为您配置此消息转换器.
@RequestBody uses implicitly a message converter to convert your data, Spring autoconfigures this message converter for you if you have JSON data-bind jars in your classpath.
