java.lang.NoSuchMethodException：com.sun.proxy ..... on struts2 actions

我使用spring AOP進行日誌記錄。該應用程序工作正常，如果我取消註釋這些行java.lang.NoSuchMethodException：com.sun.proxy ..... on struts2 actions

@Before("bean(*Action)") 
public void logActionEnter(JoinPoint jp) { 
    log.info("Entering action: " + jp.getSignature().getName()); 
}

我只是想知道。這應該起作用，但顯然沒有。

如果你是interesterd，該login()方法

public String login() throws Exception { 
    String name = getAuthService().loginUser(username, password); 

    if(name == null) { 
     setType("not_found"); 
     return "failed"; 
    } 
    if(name.equals("LOCKED")) { 
     setType("is_locked"); 
     return "failed"; 
    } 
    if(name.equals("LOCKED_LOG")) { 
     setType("login_lock"); 
     return "failed"; 
    } 

    if(name.isEmpty()) { 
     setType("auth_failed"); 
     return "failed"; 
    } 

    if(session.containsKey("user")) return "session-active"; 

    User user = getAuthService().setUserActiveNow(username); 

    session.put("user", username); 
    session.put("completeName",name); 
    session.put("access", getAuthService().getFunctionAccess(username)); 
    session.put("loginDate", user.getLastLoginDt()); 
    session.put("userId", user.getId()); 

    getAuditLogService().writeLog(username, new Date(), 
      ServletActionContext.getRequest().getRequestURL().toString(), username + ":" + name + " logged in to IVRBO"); 

    return "success-login"; 
}

編輯：我也有這個類的一個validate()方法。

編輯：這裏的XML

<?xml version="1.0" encoding="UTF-8"?> 

<beans xmlns="http://www.springframework.org/schema/beans" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <!-- beans here --> 

    <aop:aspectj-autoproxy proxy-target-class="true" /> 

    <context:component-scan base-package="com.bdo.ivr" /> 

</beans>

的方面。我使用了註釋。

import org.apache.log4j.Logger; 
import org.aspectj.lang.JoinPoint; 
import org.aspectj.lang.annotation.AfterThrowing; 
import org.aspectj.lang.annotation.Aspect; 
import org.aspectj.lang.annotation.Before; 
import org.springframework.stereotype.Component; 

@Component 
@Aspect 
public class LoggingAspect { 

    Logger log = Logger.getLogger(this.getClass()); 

    @Before("bean(*Action)") 
    public void logActionEnter(JoinPoint jp) { 
     log.info("Entering action: " + jp.getSignature().getClass() + ": " + jp.getSignature().getName()); 
    } 

    @Before("bean(*Service)") 
    public void logServiceEnter(JoinPoint jp) { 
     log.info("Entering service: " + jp.getSignature().getClass() + ": " + jp.getSignature().getName()); 
    } 

    @Before("bean(*Dao)") 
    public void logDaoEnter(JoinPoint jp) { 
     log.info("Entering DAO: " + jp.getSignature().getClass() + ": " + jp.getSignature().getName()); 
    } 

    @AfterThrowing(pointcut = 
      "bean(*Service) || bean(*Dao)", 
      throwing = "e") 
    public void logException(Exception e) { 
     log.error("Exception", e); 
    } 

}

檢查相應的罐子... – Ashish

@Ashish我有需要的罐子。我還將AOP應用於服務和DAO層，並且工作正常。當我取消註釋上面的代碼時，我的應用程序纔會崩潰。 – makalshrek

@SciasTwentyThree您可以發佈您的應用程序類路徑中的jar列表。這可能是因爲你有jar，但是你沒有包含應用程序運行時查找的方法的適當版本，或者根本沒有jar。 –

Spring缺省代理你的豆JDK代理只實現你的類的接口，而不是他們實際的類。如果login()方法只出現在實際的類上，則代理不會聲明它。

放在你的classpath CGLIB罐子和設置

<aop:aspectj-autoproxy proxy-target-class="true" />

讓Spring使用了代理實際的類類型。

我已經把'cglib-3.0.jar'。現在出現該頁面，但是，看起來我的代碼沒有正確執行。例如，'login（）'方法實際上被調用，但我無法登錄到我的應用程序。該應用程序只是讓我回到登錄頁面。 – makalshrek

@SciasTwentyThree沒有更多的細節，我們不能說。您是否嘗試過調試以查看所謂的什麼和不是什麼？ –

對不起，我現在工作。問題是我錯誤地配置了登錄處理的bean。謝謝！ – makalshrek
