1.pom.xml文件导入AOP依赖

<!--aop依赖--><dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-aop</artifactId> <version>2.3.0.RELEASE</version></dependency>

2.pom.xml导入Lombok依赖

<!--Lombok依赖--><dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional></dependency>package jmu.rjc.aspect;import lombok.AllArgsConstructor;import lombok.Data;import lombok.NoArgsConstructor;import lombok.ToString;import org.aspectj.lang.JoinPoint;import org.aspectj.lang.annotation.*;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.stereotype.Component;import org.springframework.web.context.request.RequestContextHolder;import org.springframework.web.context.request.ServletRequestAttributes;import javax.servlet.http.HttpServletRequest;//日志切面@Aspect@Componentpublic class LogAspect { private final Logger logger = LoggerFactory.getLogger(this.getClass()); //包名配置为自己的项目包名即可 @Pointcut("execution(* jmu.rjc.web.*.*(..))") public void log(){} @Before("log()") public void doBefore(JoinPoint joinPoint){ ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes(); HttpServletRequest request = attributes.getRequest(); String url = request.getRequestURL().toString(); String ip = request.getRemoteAddr(); String classMethod = joinPoint.getSignature().getDeclaringTypeName()+"."+joinPoint.getSignature().getName(); Object[] args = joinPoint.getArgs(); RequestLog requestLog = new RequestLog(url,ip,classMethod,args); logger.info("Request : {}",requestLog); } @After("log()") public void doAfter(){ logger.info("---------doAfter-------"); } @AfterReturning(returning = "result",pointcut = "log()") public void doAfterReturn(Object result){ logger.info("Result : {}"+result); } @Data @ToString @AllArgsConstructor @NoArgsConstructor private class RequestLog{ private String url; private String ip; private String classMethod; private Object[] args; }}

3.关于Lombok的注意点

Lombok的使用大大简化了开发过程,提高了开发效率,但是也存在一些隐患.比如强行侵入jar包,JDK版本升级冲突,破坏部分封装性等缺陷,使用前最好和团队商量好
