Spring Boot 简单日志配置

在生产环境中,只打印error级别的错误,在测试环境中,可以调成debug
application.properties文件

## 默认使用logback logging.level.root
=error ##warn,debug logging.level.org.springframework.web=error logging.file=d://log/my.log logging.pattern.console=%d{yyyy/MM/dd-HH:mm:ss} [%thread] %-5level %logger- %msg%n logging.pattern.file=%d{yyyy/MM/dd-HH:mm} [%thread] %-5level %logger- %msg%n
package com.wzy.ctl;


import com.wzy.entity.User;
import com.wzy.ser.UserSer;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import javax.annotation.Resource;
import java.util.List;

@RestController
@RequestMapping("user")
public class UserCtl {
    @Resource
    private UserSer u;
    private final static Logger logger = LoggerFactory.getLogger(UserCtl.class);
    @RequestMapping(method=RequestMethod.GET,value = "getUser")
    public List<User> getUser(){
        try{
            float a = 1 / 0;
        } catch (Exception e){
            logger.error("出现异常"+e.getMessage());
        }
        return u.getUser();
    }
    
}

当系统出现异常后:

有一点值得注意:当日志一直打印,会出现linux系统内存不足的情况,可以做个定时任务,定期清理一下日志
