[英]How to use AspectJ for Loggin in a maven project?
我有一個 maven Java EE 6 項目,我在每個方法中都有一個 Logger 信息,以在控制台中顯示參數的開頭和結尾。
在某些方法中,我忘記了 make,所以我想使用 aspectJ 來管理每個調用方法的開始和結束。
我使用 Jboss EAP6 作為服務器,使用 Jboss developer Studio 作為 IDE,我在網上找到了一些教程,但它總是談論 spring 或 java aspactJ 項目。 我在我的 IDE 上安裝了插件 aspectJ,我嘗試添加一個方面,它告訴我我的 maven 項目不是一個 aspectJ 項目,所以如何解決這個問題?
這是我的 maven pom.xml

這是我的界面:
public interface IClient {
void addClient(ClientBean clt);
}
這是實現:
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;
}
}
這是一個我試圖讓我的方面J的課程:
@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());
}
}
我有一個 man 類要測試,當我運行我的項目時,它讓我在控制台上沒有登錄
您的 POM 有幾個問題:
pluginManagement
部分配置,而在實際plugins
部分沒有實際使用,則不會應用AspectJ Maven Plugin 。dependencies
子部分中覆蓋以使用當前版本 1.8.4,我也建議您這樣做,因為 1.8.4與 1.8.2 相比,包含幾個修復。更新:
這是我自己的項目之一的示例配置(Java SE,沒有應用程序服務器,但它應該是等效的):
