使用AngularJS+Struts2进行前后台的数据交互与显示。
struts.xml
配置文件需要将设置extends="json-default" type="json"
<package name="default" namespace="/" extends="json-default">
<action name="ajax" class="com.Yiran583.action.ajacAction">
<result type="json"/>
</action>
</package>
后台代码：
将需要作为JSON数据传递给前台的属性设置相应的getter/setter方法
private List<Person> list = new ArrayList<Person>();
private Person person; @Override
public String execute() throws Exception {
// TODO Auto-generated method stub Person person = new Person("Yiran", 20);
Person person1 = new Person("Jiao", 22);
Person person2 = new Person("Zhangsan", 18); list.add(person1);
list.add(person2); list = JSONArray.fromObject(list); return SUCCESS;
} public List<Person> getList() {
return list;
} public void setList(List<Person> list) {
this.list = list;
}
前台：
ng-repeat 循环显示
x.name,x.age 分别是JSON对象中的属性
$scope.name = a.list; 将list对象返回的结果绑定到name上
<body ng-app>
<span id="btn" style="cursor: pointer; font-size: 20px">action</span>
<div id="rdiv" ng-controller="myCC">
要显示数据的区域
<li ng-repeat="x in names">
{{x.name+" "+x.age}}
</li>
</div> <script type="text/javascript">
function myCC($scope, $http) {
var url = "ajax.action";
$http.get(url).success(function(a) {
$scope.names = a.list;
});
}
</script>
</body>
