Struts2中iterator标签遍历map总结

Struts2中iterator标签遍历map总结收藏

针对以下几种情况的Map:

private Map map;

private Map studentMap;

private Map arrayMap;

private Map> listMap;

--------------------------------------------------------------------------------

map=new HashMap();

map.put("1", "one");

map.put("2", "two");

用法：

key:

value:

--------------------------------------------------------------------------------

studentMap=new HashMap();

studentMap.put("student1",new Student(new Long(1),"[1**********]","张三1","男",25));

studentMap.put("student2",new Student(new Long(2),"[1**********]","张三2","女",26));

studentMap.put("student3",new Student(new Long(3),"[1**********]","张三3","男",27));

用法：

--------------------------------------------------------------------------------

arrayMap=new HashMap();

arrayMap.put("arr1", new String[]{"1","2003401","leejie","male","20"});

arrayMap.put("arr2", new String[]{"2","2003402","huanglie","male","25"});

arrayMap.put("arr3", new String[]{"3","2003403","lixiaoning","male","21"});

用法

--------------------------------------------------------------------------------

listMap=new HashMap>();

List list1=new ArrayList();

list1.add(new Student(new Long(1),"[1**********]","张三1","男",25));

list1.add(new Student(new Long(2),"[1**********]","张三2","男",25));

list1.add(new Student(new Long(3),"[1**********]","张三3","男",25));

listMap.put("class1", list1);

List list2=new ArrayList();

list2.add(new Student(new Long(1),"[1**********]","李四1","男",20));

list2.add(new Student(new Long(2),"[1**********]","李四2","男",21));

list2.add(new Student(new Long(3),"[1**********]","李四3","男",22));

list2.add(new Student(new Long(4),"[1**********]","李四4","男",23));

listMap.put("class2", list2);
