springboot实现日志记录

首先开启切面：

@SpringBootApplication
@EnableAsync
@EnableAspectJAutoProxy(proxyTargetClass = true)
public class DemoApplication {
    
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
    
}
然后pom.xml引入依赖

<!-- https://mvnrepository.com/artifact/org.aspectj/aspectjrt -->
<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjrt</artifactId>
    <version>1.9.4</version>
</dependency>
<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjweaver</artifactId>
    <version>1.9.2</version>
</dependency>

日志注解类
import java.lang.annotation.*;

@Target({ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface ELog {
    String describe() default "";
    String operateMethod() default "";
}

切面类
