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>
