@RestControllerAdvice(basePackages = "com.example.demo.controller")//切面
public class GlobalExceptionHandler {
    @ExceptionHandler(RuntimeException.class)//拦截的错误
    @ResponseBody
public Map<String,String> error(){
    HashMap<String, String> map = new HashMap<>();
    map.put("errorCode","500");
    map.put("errorMsg","运行错误");
    return  map;
}
