- Spring Boot 自带日志框架，需要先剔除自带的
集成日志

- 在resources目录下新建log4j.properties配置文件如下：
log4j.rootLogger=DEBUG,stdout,file
log4j.additivity.org.apache=true
# 控制台
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.threshold=INFO
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%-5p %c{1}:%L - %m%n
# 每日文件保存
log4j.appender.file=org.apache.log4j.DailyRollingFileAppender
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.DatePattern='.'yyyy-MM-dd
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
log4j.appender.file.Threshold=INFO
log4j.appender.file.append=true
log4j.appender.file.File=/Users/usr/Desktop/log/log.log
- 使用方法
定义
final static Logger logger = LoggerFactory.getLogger(UsersController.class);
使用
@ApiOperation( "登录")
@PostMapping("login")
public Result doLogin(@RequestBody UsersBo usersBo){
Users users = usersService.doLogin(usersBo);
if (users == null){
return Result.error(CodeMsg.USERNAME_PWD_ERROR);
}
logger.info("用户" + usersBo.getUsername() +"登录系统");
return Result.success(users);
}

- 只需要在需要设置cookie的地方 直接set就行，但是cookie的value是String类型 不能直接把对象塞进去。要先把对象转Sting，前端再做处理
