[英]Spring MVC - RequestBody not working (JSON)
I'm having a simple controller method: 我有一个简单的控制器方法:
@RequestMapping(value = "/test", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE)
@ResponseStatus(value = HttpStatus.OK)
@ResponseBody
public void postCheck(@RequestBody TestDTO testDTO, HttpServletRequest request) {
System.out.println(testDTO);
}
the DTO is: DTO是:
public class TestDTO {
private String hello;
public TestDTO() {
}
public String getHello() {
return hello;
}
public void setHello(String hello) {
this.hello = hello;
}
} }
When i try to post a request to that url i get an ERROR 400 Message response "The request sent by the client was syntactically incorrect." 当我尝试将请求发布到该URL时,出现错误400消息响应“客户端发送的请求在语法上不正确。” (the controller method is not being invoked at all) (完全不调用controller方法)
I tried posting from Chrome's poster plugin AND from jquery's ajax: 我尝试从Chrome的海报插件和jquery的ajax发布:
$.ajax({
type : "POST",
url : "http://localhost:8080/NG_Admin/test",
contentType : "application/json",
dataType : "json",
data : JSON.stringify(eval({"hello" : "world"})),
error : function(data) {
alert('Error');
},
success : function(data) {
alert('Success!');
}
});
}
Any ideas? 有任何想法吗? (btw I use both 'jackson-mapper-asl', version:'1.9.12', 'jackson-core-asl', version:'1.9.12') (顺便说一句,我同时使用了'jackson-mapper-asl'版本:'1.9.12','jackson-core-asl'版本:'1.9.12')
Thanks 谢谢
OK,I fixed the problem, 好,我解决了这个问题,
Had to add a filter for all request that handles CORS access. 必须为处理CORS访问的所有请求添加过滤器。
