Java多模块项目,分离打包后统一异常处理失效

问题描述:

项目是基于SpringBoot的多模块项目,main方法在manage模块中,使用maven-assembly-plugin完成打包,打包之后将配置文件和项目中用到的jar包分离,通过java -Xms512m -Xmx1g -cp conf:lib/* com.xxx.xxx.App命令启动服务,但统一异常处理失效

尝试的方法

  1. 修改basePackages参数,指定扫描范围吗,但没有生效
@RestControllerAdvice(basePackages = {"com.amt"})
  1. 将统一异常类放在基础模块中,但没有生效

Maven配置信息

<build>
    <plugins>
        <!--编译插件-->

                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

统一异常处理类

@Slf4j
@RestControllerAdvice()
public class GlobalExceptionHandle {
    /**
     * 服务器报错统一返回信息
     */
    private static final String INTERNAL_SERVER_ERROR = "内部服务器错误";

    /**

     * @see com.amt.itms.verify.ValidatorUtil
     */
    @ExceptionHandler(value =  {
        ConstraintNotMatchException.class}
    )
    public ResponseData constraintNotMatchExceptionHandler(
        ConstraintNotMatchException e) {
        return new ResponseData(ResponseData.ERROR, e.getMessage());
    }

    /**
     * SpringBoot参数缺失统一处理
     *
     * @param e
     * @return
     */
    @ExceptionHandler(value =  {
        MissingServletRequestParameterException.class}
    )
    public ResponseData missingServletRequestParameterExceptionHandler(
        MissingServletRequestParameterException e) {
        log.warn("method:[{}], message:[{}], time:[{}]",
            "missingServletRequestParameterExceptionHandler", e.getMessage(),
            System.currentTimeMillis());

        ResponseData responseData = new ResponseData(ResponseData.ERROR,
                e.getMessage());

        return responseData;
    }

    /**
     * 请求方式错误
     *
     * @return
     */
    @ExceptionHandler(value =  {
        HttpRequestMethodNotSupportedException.class}
    )
    public ResponseData httpRequestMethodNotSupportedExceptionHandler() {
        return new ResponseData(ResponseData.ERROR, "HTTP请求方法错误");
    }

    /**
     * Manager服务统一异常处理
     *
     * @param e
     * @return
     */
    @ExceptionHandler(value =  {
        ManagerServerException.class}
    )
    public ResponseData managerServerExceptionExceptionHandler(
        ManagerServerException e) {
        ResponseData responseData;

        if (StringUtils.hasLength(e.getMessage())) {
            responseData = new ResponseData(ResponseData.ERROR, e.getMessage());
        } else {
            responseData = new ResponseData(ResponseData.ERROR,
                    INTERNAL_SERVER_ERROR);
        }

        return responseData;
    }

    @ExceptionHandler(value =  {
        Exception.class}
    )
    public ResponseData exceptionHandle(Exception e) {
        ResponseData responseData;

        if (e instanceof NoHandlerFoundException) {
            responseData = new ResponseData(ResponseData.ERROR, "接口地址不存在");
        } else {
            responseData = new ResponseData(ResponseData.ERROR, e.getMessage());
        }

        log.error("method:{}; exception:{};time:{}", "exceptionHandle", e,
            System.currentTimeMillis());
        e.printStackTrace();

        return responseData;
    }
}

遇到这个问题有点抓狂了,在idea中都是生效的,打包为一个单独的jar包也是生效的,但分离打包之后就失效了,还请各位大佬帮帮忙!

无意间看到一篇文章,看到了解决此问题的方法。是我的项目中有两个统一异常处理类,删除其中一个即可
