SpringBoot统一日志处理

1、第一步：引入logback依赖，建议直接mybatisplus，自带

请参考https://blog.csdn.net/zhouhengzhe/article/details/118060155

2、把yml中所有关于日志的信息全删了

3、在resources下添加logback-spring.xml

/Users/mac/Documents/logs/edu 这个路径自行修改

4、配合统一异常

可以参考https://blog.csdn.net/zhouhengzhe/article/details/118064739

package com.zhz.servicebase.execptionhandler;


import com.zhz.common.utils.ExceptionUtil;
import com.zhz.common.utils.R;
import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RestControllerAdvice;

/**
 * @author mac
 * 统一异常处理类
 */
@RestControllerAdvice
@Slf4j
public class GlobalExceptionHandler {
    /**
     * 指定出现什么异常执行这个方法
     * @param e 异常
     * @return
     */
    @ExceptionHandler(Exception.class)
    public R error(Exception e){
        log.error(ExceptionUtil.getMessage(e));
        e.printStackTrace();
        return R.error().message("执行了全局异常处理");
    }
    /**
     * 特定异常处理
     */
    @ExceptionHandler(ArithmeticException.class)
    public R error(ArithmeticException e){
        log.error(ExceptionUtil.getMessage(e));
        e.printStackTrace();
        return R.error().message("执行了Arithmetic异常处理");
    }
    /**
     * 自定义异常处理
     */
    @ExceptionHandler(GuliException.class)
    public R error(GuliException e){
        log.error(ExceptionUtil.getMessage(e));
        e.printStackTrace();
        return R.error().code(e.getCode()).message(e.getMsg());
    }
}

为了输出更多的信息，也就是堆栈信息的处理：ExceptionUtil.java

package com.zhz.common.utils;

import java.io.IOException;
import java.io.PrintWriter;
import java.io.StringWriter;

/**
 * @author mac
 */
public class ExceptionUtil {
    public static String getMessage(Exception e) {
        StringWriter sw=null;
        PrintWriter pw=null;
        try {
            sw=new StringWriter();
            pw=new PrintWriter(sw);
            //将出错的栈信息输出到PrintWriter中
            e.printStackTrace(pw);
            pw.flush();
            sw.flush();
        }finally {
            if (sw!=null){
                try {
                    sw.close();
                }catch (IOException e1){
                    e1.printStackTrace();
                }
            }
            if (pw!=null){
                pw.close();
            }
        }
        return sw.toString();
    }
}
