页面传输Json对象至Action(Strust2)
1. struts 配置, 添加拦截器
<package name="Struts2_AJAX_SPC" extends="json-default">
<interceptors>
<interceptor-stack name="myDefaultStack">
<interceptor-ref name="json"/>
<interceptor-ref name="defaultStack"/>
</interceptor-stack>
</interceptors>
<default-interceptor-ref name="myDefaultStack"/>
<action name="xxxx" class="jsonToBeanAction" method="putManMethod">
<result type="json"/>
</action>
</package>
2 页面
<%@ page contentType="text/html; charset=utf-8"%>
<%
String path = request.getContextPath();
%>
<html>
<head>
<SCRIPT type="text/javascript" src="<%=path%>/js/jquery-1.6.2.js"></SCRIPT>
<script type="text/javascript" src="<%=path%>/js/ext-base.js"></script>

</head>
<body>
<script>
var jsonText = "{'name':'Jack1','age':'10','person':{'name':'Jack2','age':'20'} ,'names': ['name1','name2'], 'persons':[{'name':'Jack3','age':'30'},{'name':'Jack4','age':'40'} ]}";
function callByJquery() {
$.ajax({
type : 'POST',
data : jsonText,
url : "viewOCAPList.action",
success : function(msg) {
alert("success");
},
});
}
function callByExt() {
Ext.Ajax.defaultHeaders = {
'Accept' : 'application/json',
'Content-Type' : "application/json; charset=UTF-8"
};
Ext.Ajax.request({
timeout : 120000,
url : "viewOCAPList.action",
success : function(response) {
alert("success");
},
failure : function(resposne) {
},
params : jsonText
});
}
</script>
<a href="#" onclick="callByJquery()">JQuery提交</a>
<br />
<a href="#" onclick="callByExt()">Ext提交</a>
<br />
</body>
</html>
