我是在action里面添加属性来自动传输json的
private Integer len;
private String root;
public String findAllStu() throws ParseException, IOException {
List<Student> stus = studentService.getAllStu();
len = stus.size();
root = JsonUtil.listToJson(stus, "student_list");
return "list";
}
struts.xml中：
<action name="studentAction^*" class="cn.edu.jmu.judgeOnline.action.StudentAction"
method="{1}">
<result name="list" type="json"></result>
</action>
前台接收数据：
{"len":1,"root":"[{'studentId':'180','studentName':'张三','classInfo.classId':'140','studentNo':'JM123456','sex':'0','birthday':'2014-05-01','address':'','tel':'','email':'','mobilephone':'','userInfo.userId':'1'}]"}
js中的接收store：
var store = new Ext.data.Store({
proxy: new Ext.data.HttpProxy({url:"studentAction^findAllStu"}),
reader: new Ext.data.JsonReader({
totalProperty: 'len',
root: 'root'
}, [
{name: 'studentName'}
])
});
觉得是数据的格式不对，就是store中的root应该是一个数组类型的，而我传过去的是一个字符串，这个怎么解决？求大神啊！！！
