但是，按照下面的逻辑顺序来执行时却没有发生错误: 我想请问一下，这是为什么?如何解决?请给出具体的代码，先谢了！ |

Service层哪来的WebApplicationContext? 只有类装载器在装载MVC层时才加载WebApplicationContext。
一个最简单的解决办法是：
@Service
public class SystemManageServiceImpl implements SystemManageService,ApplicationListener<ContextRefreshedEvent>{
private static ApplicationContext applicationContext = null;
public void onApplicationEvent(ContextRefreshedEvent event){
if(this.applicationContext == null){
this.applicationContext = event.getApplicationContext();
}
}
public Boolean checkUnique(){
//this.applicationContext.getBean(...);
}
}
另外楼主用了内省和反射，效率低啊。既然所有Manage类都有checkUnique方法，为什么不用接口或抽象类？这样this.applicationContext.getBean(…)赋给接口或抽象类，就可以直接执行checkUnique方法啊。 |

按照你的方法，我的问题已经解决了！ |
 60分 |
public interface CheckUnique{
public Boolean checkUnique(String name, String value);
}
public class UserManageServiceImpl implements?UserManageService, CheckUnique{
public Boolean checkUnique(String name, String value){
//todo
}
}
public class SystemDataManageServiceImpl implements SystemDataManageService, CheckUnique{
public Boolean checkUnique(String name, String value){
//todo
}
}
//调用
CheckUnique checkUnique = (CheckUnique)this.applicationContext.getBean(u2eMapping.getBeanName);//保证u2eMapping缓存里放的bean都是CheckUnique的实现类
return checkUnique.checkUnique(...,...);
