[SpelEvaluationException]异常报错 #10

Closed MagikLau closed 6 years ago

经常遇到这个问题，不知道是不是因为和其他框架集成之后冲突了 集成的框架有：SpringBoot、SpringSecurity、SpringMVC、SpringDataJPA 本次错误出现在发送微信消息之后，经断点调试，在return WxMessage时会进坑，怀疑是使用微信接口和Security框架冲突了，具体情况还在检查中…… Java代码如下：

    @RequestMapping(value = "/sendByParam", method = RequestMethod.POST)
    @ResponseBody
    public WxMessage sendMsgByParam(@RequestParam("content") String content,
                                    @RequestParam(value = "academy", required = false)String academy,
                                    @RequestParam(value = "major", required = false)String major,
                                    @RequestParam(value = "gradeClass", required = false)Integer gradeClass,
                                    @RequestParam(value = "direction", required = false)String direction ) {
        try{
            System.out.println("sendMsgByParam:"+content);
            System.out.println("Param: {academy: "+academy+", major: "+major+", gradeClass: "+gradeClass+", direction: "+direction+"}");
            List<Student> studentList = studentService.findByMajorAndGradeClassAndOpenIDNotNull(major, gradeClass);
            System.out.println("studentList: "+studentList);
            List<String>openIdList = new ArrayList<>();

            for( Student student : studentList ){
                String openID = student.getOpenID();
                if( openID != null ){
                    openIdList.add(openID);
                }
            }
            return WxMessage.Text.builder()
                    .content(content)
                    .toGroup(openIdList)
                    .build();
        }catch (Exception e){
            e.printStackTrace();
        }
        return null;
    }

服务器报错log：

前端发送请求的JS代码如下，可以正常alert成功信息：

<script type="text/javascript">
    function sendGroupMsg02() {
        var major = $("#major").val();
        var gradeClass = $("#gradeClass").val();
        var textarea02 = $("#textarea02").val();
        var preCheck = "";
        if( textarea02 === null || textarea02 === "" ){
            preCheck = "[无内容]";
        }
        if( preCheck.length > 0 ){//初步检查
            preCheck += "异常，请先处理";
            alert(preCheck);
        }else {//检查无误，发送请求
            $.ajax({
                url: "/messages/sendByParam",
                type: "POST",
                data: "content="+textarea02+"&major="+major+"&gradeClass="+gradeClass,
                success: function (data) {
                    alert('Sent successful: '+data);
                    window.location.href = '/messages';

                },
                error: function (data) {
                    console.log(data);
                    alert('error - '+data);
                }
            });
        }
    }
</script>

异常原因已查明，是群发消息成功的回调中的处理逻辑没有做空判断，现已修复。 但本地无法重现该异常，等待后续调试观察

HikariShine commented 6 years ago

使用LauItachi的项目WeChatPlatformApplication重现该异常，发现是因为项目中的GlobalExceptionHandler这个ControllerAdvice覆盖了默认的异常处理器

@ControllerAdvice
public class GlobalExceptionHandler {
    public static final String DEFAULT_ERROR_VIEW = "error";

    @ExceptionHandler(value = Exception.class)
    public ModelAndView defaultErrorHandler(HttpServletRequest req, Exception e) throws Exception {
        ModelAndView mav = new ModelAndView();
        mav.addObject("exception", e);
        mav.addObject("url", req.getRequestURL());
        mav.setViewName(DEFAULT_ERROR_VIEW);
        return mav;
    }
}

但是视图仍然是默认的视图名，仍然会使用ErrorMvcAutoConfiguration的defaultErrorView视图来进行渲染，在渲染是defaultErrorView中需要的placeholder中的属性值在上面的mav中没有，导致了上面的报错信息。完善上面的异常处理器即可。 顺便一提，默认的异常处理器是BasicErrorController，其中的model属性是全的，包含了默认视图中需要使用的全部信息。可以参考这个controller

已在GlobalExceptionHandler的defaultErrorHandler添加打印异常入日志，感谢大佬各种姿势调试orz
