创建一个SpringBoot 项目
引入相关依赖
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjweaver</artifactId>
</dependency>
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjrt</artifactId>
</dependency>
被增强类
@Service
public class MyService {
private static final Logger LOGGER = LoggerFactory.getLogger(MyService.class);
final public void foo() {
LOGGER.info("foo()");
bar();
}
public void bar() {
LOGGER.info("bar()");
}
}
切面
@Aspect
public class MyAspect {
private static final Logger LOGGER = LoggerFactory.getLogger(MyAspect.class);
@Before("execution(* com.xtransformers.service.MyService.*())")
public void before() {
LOGGER.info("before()");
}
}
主类
@SpringBootApplication
public class AopAgentDemoApplication {
private static final Logger LOGGER = LoggerFactory.getLogger(AopAgentDemoApplication.class);
public static void main(String[] args) {
ConfigurableApplicationContext context = SpringApplication.run(AopAgentDemoApplication.class, args);
MyService myService = context.getBean(MyService.class);
LOGGER.info("MyService: {}", myService.getClass());
myService.foo();
context.close();
}
}
配置 aop.xml 文件（路径：resources/META-INF/aop.xml）
<aspectj>
<aspects>
<aspect name="com.xtransformers.aop.MyAspect"/>
<weaver options="-verbose -showWeaveInfo">
<include within="com.xtransformers.service.MyService"/>
<include within="com.xtransformers.aop.MyAspect"/>
</weaver>
</aspects>
</aspectj>
在 VM options 里增加 javaagent
# 需要把Maven Repo路径（/Users/daniel/java/maven/repository）修改为自己的仓库路径
-javaagent:/Users/daniel/java/maven/repository/org/aspectj/aspectjweaver/1.9.7/aspectjweaver-1.9.7.jar
