测试代码
package com;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

public class Demo {

public static void main(String[] args) {
ApplicationContext cxt =
new FileSystemXmlApplicationContext("classpath:applicationContext.xml");
ServiceImpl service = (ServiceImpl)cxt.getBean("service");
System.out.println(service);
service.doTest();
}
}

这个配置相信大家都会，但是在Myeclipse6.0下导入spring的jar包。会报这个错误
net.sf.cglib.core.CodeGenerationException: java.lang.reflect.InvocationTargetException-->null
发现竟然是jar包不兼容导致。是Myeclipse6.0自动导入的spring的jar包问题。是自动导入的cglib包有问题。
自己实现cglib也出现过同样的问题。后面自己导入cglib包，发现少asm包，需要导入 hibernate包就可以正常运行。
解决方案：
  把自动导入的jar包删除。重新导入jar包即可。
