java.lang.NoSuchMethodException：com.sun.proxy .....关于struts2的动作

时间：2013-10-29 07:29:52

标签： java spring struts2 spring-aop

我正在使用spring AOP进行日志记录。如果我取消注释这些行，该应用程序工作正常

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

我只是想知道。这应该有效，但显然没有。

如果您有兴趣，请使用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";
}

编辑：我在这个课程上也有一个validate()方法。

编辑：这是XML 

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

       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>

方面。我使用了注释。

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);
    } 

}

默认情况下，Spring使用JDK代理代理您的bean，JDK代理只实现您的类的接口，而不是它们的实际类。如果login()方法仅出现在实际类中，则代理将不会声明它。

将CGLIB个jar放在类路径上并设置

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

因此Spring使用代理的实际类类型。
