[英]How to use AspectJ for Loggin in a maven project?
我有一个 maven Java EE 6 项目,我在每个方法中都有一个 Logger 信息,以在控制台中显示参数的开头和结尾。
在某些方法中,我忘记了 make,所以我想使用 aspectJ 来管理每个调用方法的开始和结束。
我使用 Jboss EAP6 作为服务器,使用 Jboss developer Studio 作为 IDE,我在网上找到了一些教程,但它总是谈论 spring 或 java aspactJ 项目。 我在我的 IDE 上安装了插件 aspectJ,我尝试添加一个方面,它告诉我我的 maven 项目不是一个 aspectJ 项目,所以如何解决这个问题?
这是我的 maven pom.xml

这是我的界面:
public interface IClient {
void addClient(ClientBean clt);
}
这是实现:
public class ClientImpl implements IClient {
private List<ClientBean> ListOfCustomers;
public ClientImpl() {
setListOfCustomers(new ArrayList<ClientBean>());
}
public void addClient(ClientBean clt) {
ListOfCustomers.add(clt);
}
public List<ClientBean> getListOfCustomers() {
return ListOfCustomers;
}
public void setListOfCustomers(List<ClientBean> listOfCustomers) {
ListOfCustomers = listOfCustomers;
}
}
这是一个我试图让我的方面J的课程:
@Aspect
public class ClientAspect {
@Pointcut("execution(* *.*(..))")
void anyCallMethod() {}
@Before(value = "anyCallMethod()")
public void befor(JoinPoint joinPoint) {
System.out.println("Before, class: "
+ joinPoint.getSignature().getDeclaringType().getSimpleName()
+ ", method: " + joinPoint.getSignature().getName());
}
@After(value = "anyCallMethod()")
public void after(JoinPoint joinPoint) {
System.out.println("After, class: "
+ joinPoint.getSignature().getDeclaringType().getSimpleName()
+ ", method: " + joinPoint.getSignature().getName());
}
}
我有一个 man 类要测试,当我运行我的项目时,它让我在控制台上没有登录
您的 POM 有几个问题:
pluginManagement
部分配置,而在实际plugins
部分没有实际使用,则不会应用AspectJ Maven Plugin 。dependencies
子部分中覆盖以使用当前版本 1.8.4,我也建议您这样做,因为 1.8.4与 1.8.2 相比,包含几个修复。更新:
这是我自己的项目之一的示例配置(Java SE,没有应用程序服务器,但它应该是等效的):
