我无法让LTW在带有嵌入式Tomcat的Spring Boot 1.2.2中工作。
我的应用程序是WAR文件,而不是.JAR文件。当我在DEBUG中运行时,即使点击应该与切入点匹配的调用,它也永远不会停留在我的方面,所以这就是我认为它不起作用的方式......
我的运行脚本执行此操作:
-javaagent:path/to/spring-instrument-xxx.jar -javaagent:path/to/aspectjweaver-1.2.8.jar
在Spring Boot中,我将此AOP Config作为ApplicationInitializer加载,因此它立即存在于父ApplicationContext中,之后应该存在于我的所有嵌入式tomcat Web应用程序上下文中。
@EnableLoadTimeWeaving(aspectjWeaving=AspectJWeaving.ENABLED)
@Configuration
public class AopConfig {
private Log log = LogFactory.getLog(AopConfig.class);
public AopConfig() {
log.info("Creating AopConfig");
}
@Bean
public LoadTimeWeaver loadTimeWeaver() {
log.info("Creating InstrumentationLoadTimeWeaver");
return new InstrumentationLoadTimeWeaver();
}
}
我的看点如下:
package my.aop.profiler.MethodTimerAspect;
@Aspect
public class MethodTimerAspect {
private static final String DELIMITER = "|";
private static final String PROFILER = "profiler";
private static final String DATE_FORMAT = "h:mm:ss";
private static final Log LOG = LogFactory.getLog(PROFILER);
public MethodTimerAspect() {}
@Pointcut("execution (* my.web.*Controller.*(..))")
protected void controllers() {}
@Pointcut("execution (* my.services..*Facade.*(..))")
protected void services() {}
@Pointcut("execution (* my.services..*Exchange.*(..))")
protected void data() {}
/**
* If profiling is enabled with trace, it will log the amount of time
* spent in the method
*
* @param joinPoint
* @return Object
* @throws Throwable
*/
@Around("controllers() || services() || data()")
public Object doProfiling(ProceedingJoinPoint joinPoint) throws Throwable {
// (...)
}
}
My Embedded WAR的META-INF / aop.xml是这样的:
<!DOCTYPE aspectj PUBLIC "-//AspectJ//DTD//EN" "http://www.eclipse.org/aspectj/dtd/aspectj.dtd">
<aspectj>
<weaver>
<!-- only weave classes in our application-specific packages -->
<include within="cdot.*"/>
</weaver>
<aspects>
<!-- weave in just this aspect -->
<aspect name="my.aop.profiler.MethodTimerAspect"/>
</aspects>
</aspectj>
答案 0 :(得分:0)
两个想法:
您可能希望更改其中一个切入点以查找子包(使用..
语法而不是.
):
@Pointcut("execution (* my.web..*Controller.*(..))")
这同样适用于您的 aop.xml :
<include within="cdot..*"/>
我认为my.web
被您故意更改并实际读取cdot.something
,否则切入点将无法匹配。
