spring中bean的高级属性之list, set, map以及props元素(含举例)

 list, set, map和props元素分别用来设置类型为List，Set，Map和Propertis的属性值。分别用来为bean传入集合值。
 对应的spring的配置文件举例如下：

    对应的java类为:
java 代码

public   class  Chinese  implements  People   ...{
     private  List friends  =   new  ArrayList();
     private  Map score  =   new  HashMap();
     private  Properties basicInfo  =   new  Properties();
     private  Set interest  =   new  HashSet();
     // 省略对应set方法
     .
}
