- 你可以参考下这篇文章：Map集合和List集合总结
- 除此之外, 这篇博客: 封装数据到List集合和Map集合中的 封装数据到Map集合 部分也许能够解决你的问题, 你可以仔细阅读以下内容或者直接跳转源博客中阅读:
- 声明map集合
public class MapAction extends ActionSupport{ private Map<String,User> map; @Override public String execute() throws Exception { System.out.println(map); return NONE; } }- 生成get和set方法
public class MapAction extends ActionSupport{ private Map<String,User> map;//这里的User类还是和上面的一样 public Map<String, User> getMap() { return map; } public void setMap(Map<String, User> map) { this.map = map; } @Override public String execute() throws Exception { System.out.println(map); System.out.println(map.get("one").getAddress()); System.out.println(map.get("two").getUsername()); return NONE; } }- 在表单输入项的name属性值里面写表达式
