The request sent by the client was syntactically incorrect.
这个问题是因为 SpringMvc controller 里面的方法参数和请求参数不匹配。
请求参数在 Contoller 的方法参数对象中不存在则会报这个错误。
如 :
Controller 里面的方法
@RequestMapping(value = "/login/signin", method = RequestMethod.POST) public @ResponseBody Person login(HttpServletRequest request, @RequestBody Person person){ //... } public class Person { private int id; private String name; //... set get } function init() { var url = "login/signin"; var req = new Object(); req.id = 1; req.name = "aaa"; req.age = 18; // Person 没有age 属性. (function() { $.ajax({ type : 'post', url : url, contentType : 'application/json', datatype : 'json', data : JSON.stringify(req), success : processSuccess, error : processError }); })(); function processSuccess(result) { alert("success--"+result); } function processError(result) { alert("error--"+result); } }
