$.ajax({ url:"/ErrorController/ajaxError", type:"POST", async:false, success:function (data) { if (data.status ==200 && data.msg == "OK"){ alert("succcess"); } else{ alert("error:" +data.msg); } }, error: function (response,ajaxOptions,thrownError) { alert("error"); } });
handler.java
@RestController public class AjaxExceptionHandler { @ExceptionHandler(value = Exception.class) public JSONResult defaultExceptionHandler(HttpServletRequest request,Exception e) throws Exception{ e.printStackTrace(); return JSONResult.errorException(e.getMessage()); } }
ajaxError.html:
<!DOCTYPE html> <html lang="en" xmlns:th="http://www.thymeleaf.org"> <head> <meta charset="UTF-8"> <title>异常捕获</title> <script src="https://cdn.bootcss.com/jquery/3.4.1/jquery.min.js"></script> </head> <body> <h1>测试ajax错误异常</h1> <script th:src="@{/js/ajaxerror.js}"></script> </body> </html>
controller里面的代码:
@RequestMapping("/testAjaxError") public String testAjaxError(){ return "/thymeleaf/ajaxError"; } @RequestMapping("/ajaxError") @ResponseBody public JSONResult ajaxError(){ int a=1/0; return JSONResult.ok(); }
将类注解
@ControllerAdvice
改成
@RestControllerAdvice
就好了
AjaxExceptionHandler类上没有加@controlleradvice注解,可能异常统一处理并未生效,导致进入了error function
