springboot项目和spring的项目的使用有点不同，因为springboot把一些依赖自动引入了所以spring的项目多引几个依赖
1.springboot项目只需要引这一个就可以了
<!-- https://mvnrepository.com/artifact/org.projectlombok/lombok -->
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.18.4</version>
<scope>provided</scope>
</dependency>
spring项目的pom引用全部依赖
<!-- https://mvnrepository.com/artifact/org.projectlombok/lombok -->
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.18.0</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.slf4j/slf4j-api -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.25</version>
</dependency>
<!-- https://mvnrepository.com/artifact/ch.qos.logback/logback-classic -->
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.2.3</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.junit.jupiter/junit-jupiter-api -->
<dependency>
<groupId>org.junit.jupiter</groupId>
<artifactId>junit-jupiter-api</artifactId>
<version>5.2.0</version>
<scope>test</scope>
</dependency>
2.配置文件配置
logging:
level:
root: info
com.cloud: debug
file: logs/${spring.application.name}.log
3.ide 装lombok插件（很简单 自行百度）
4.代码中使用
4.结果（会在你项目同级目录创建log文件夹并以服务名创建log日志文件）
