java - spring mvc上传文件超过设定大小异常处理客户端无响应

Question

spring mvc上传文件超过设定大小异常处理客户端无响应;

controller类

    @RequestMapping(path = "/file", method = RequestMethod.POST)
    public UploadMsg uploadFile(@RequestParam("uploadFile") MultipartFile file, String userCode) throws Exception {
        String fileId = genFileId();
        saveFileToSystem(file, fileId);
        UploadMsg uploadMsg = getUploadMsg(userCode, fileId, file.getSize());
        return uploadMsg;
    }
    
    @ExceptionHandler(MaxUploadSizeExceededException.class)
    public ResponseEntity<String> handleException(MaxUploadSizeExceededException ex) {
        System.out.println("=====================" + ex.getClass().getName());
        return ResponseEntity.ok("ok");
    }

spring配置文件配置文件大小不能超过1M

    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <property name="defaultEncoding" value="UTF-8"/>
        <property name="maxUploadSize" value="#{1*1024*1024}"/>
        <property name="resolveLazily" value="true"/>
    </bean>

下面是我用小于1M的文件访问时的情况

这是上传失败的情况

下面是我的日志打印情况

=====================org.springframework.web.multipart.MaxUploadSizeExceededException

这句是我在@ExceptionHandler(MaxUploadSizeExceededException.class)注解的方法中打印的，我也在这个方法中作了响应处理，但是客户端访问的时候就会显示无响应，不知道是什么鬼，求大神解答！！！！

Answer 1

Saya menemui jawapan di sini mengenai penyelesaian gelung tak terhingga mvc spring mvc
Ia dikatakan sebagai pepijat dalam tomcat Saya cuba menjalankannya dengan jeti dan ternyata tidak ada masalah tomcat, saya belum mengujinya lagi.

Answer 2

@ExceptionHandler(MaxUploadSizeExceededException.class)
@ResponseBody
public ResponseEntity<String> handleException(MaxUploadSizeExceededException ex) {
    System.out.println("=====================" + ex.getClass().getName());
    return ResponseEntity.ok("ok");
}

Lihat jika ada yang hilang @ResponseBody.

Answer 3

Weblogic juga mengalami masalah ini, masa muat naik imej, status pelanggan masih belum selesai, dan tiada respons @ExceptionHandler dan @ResponseBody telah ditulis untuk mengembalikan objek peta, tetapi pelanggan tidak bertindak balas mengesyaki bahawa weblogic belum memproses respons
