微服务下全局异常处理方案

1、新建jhjcn-common-base基础工程

2、自定义全局异常类BaseException

 

package com.jhjcn.common.base.exception;

/**
 * @Deacription TODO
 * @Author jianhua.hong
 * @Date 2020/2/25 9:56
 **/
public class BaseException extends RuntimeException {

    private String code;

    private String message;

    public BaseException(String message) {
        this.message = message;
    }

    public BaseException(String code, String message) {
        this.code = code;
        this.message = message;
    }

    public BaseException(Throwable cause) {
        super(cause);
    }

    public String getCode() {
        return code;
    }

    @Override
    public String getMessage() {
        return message;
    }
}

3、异常工具类

 

package com.jhjcn.common.base.exception;

/**
 * @Deacription TODO
 * @Author jianhua.hong
 * @Date 2019/11/19 19:41
 **/
public class ExceptionUtils {
    public static String getStackTraceString(Throwable ex) {
        StackTraceElement[] traceElements = ex.getStackTrace();

        StringBuilder traceBuilder = new StringBuilder();

        if (traceElements != null && traceElements.length > 0) {
            for (StackTraceElement traceElement : traceElements) {
                traceBuilder.append(traceElement.toString());
                traceBuilder.append("\n");
            }
        }

        return traceBuilder.toString();
    }
}

4、自定义异常处理抽象类BaseExceptionHandler

 

package com.jhjcn.common.base.exception;

import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;
