Question

我有一个switchyard应用程序，我在那里定义了一个用于加载应用程序上下文的bean类。

但是，每当我尝试加载应用程序上下文时，我都会收到以下错误：

**30 May 2015 15:52:15,510 ERROR [com.ip.fsw.tt.db.DBHandlerBean] (MSC service thread 1-8) DBHandlerBean|0|Error occured while bean initialization : Unexpected exception parsing XML document from class path resource [applicationContext.xml]; nested exception is java.lang.NoClassDefFoundError: org/springframework/aop/config/AopNamespaceUtils**

这是我的applicationContext.xml文件：

这是我的DBHandler类，我正在尝试加载应用程序上下文：

package com.ip.fsw.tt.db;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.switchyard.component.bean.Service;

import com.ip.common.logging.jb.Logger;
import com.ip.fsw.tt.db.facade.DaoTicketFacade;

@Service(DBHandler.class)
public class DBHandlerBean implements DBHandler {
    private Logger logger = Logger.getLogger(DBHandlerBean.class);
    public static DaoTicketFacade ttfacade;
    public DBHandlerBean() {
        logger.info("DBHandlerBean",0,"Loading AppContext","");
        if(loadAppContext()){
            logger.info("DBHandlerBean",0,"AppContext Successfully loaded","");
        }
    }

    private boolean loadAppContext() {
        try {
            ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
            ttfacade = (DaoTicketFacade)context.getBean("ttfacade");
        } catch(BeansException e) {
            logger.error("DBHandlerBean",0,"Error occured while bean initialization : "+e.getMessage(),"");
        } catch (Exception e) {
            logger.error("DBHandlerBean",0,"Error occured while loading the application context : "+e.getMessage(),"");
        } 
        if(ttfacade!=null){
            logger.info("DBHandlerBean",0,"Spring context loaded","");  
            return true;
        } else {
            logger.error("DBHandlerBean",0,"Spring context could not be loaded ","");
        }
        return false;
    }

    @Override
    public DaoTicketFacade getFacade() {
        // TODO Auto-generated method stub
        return null;
    }
}

现在请告诉我如何解决这个问题。

修改

Answer 1

当您在编译期间拥有该类但在运行时它不存在时，通常会抛出

NoClassDefFoundError。

请针对任何jar冲突彻底检查您的maven依赖项。这可能是NoClassDefFoundError的可能原因。

同时检查你的pom.xml并导航到依赖关系层次结构选项卡，以验证你是否两次看不到同一个不同版本的jar。

如果您确实有jar冲突，则必须根据您使用特定版本的要求删除其中一个冲突。

在我的情况下，spring-aop jar在编译时出现，但是当我将项目部署到JBoss EAP服务器时，它无法找到spring-aop jar。所以我在JBoss EAP模块目录中添加了spring-aop jar，之后我的项目选择了jar文件。

Answer 2

您正在混合命名空间版本（3.1,3.0,2.0）。

请遵循使用3.2

的示例

＆＃13;

嵌套异常是java.lang.NoClassDefFoundError：org / springframework / aop / config / AopNamespaceUtils
