struts2 + json




Insert title here


function getAjaxObject(){
var xmlhttp=null;
if(window.XMLHttpRequest){
xmlhttp=new XMLHttpRequest();
}else{
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
return xmlhttp;
}

function tt(){
var userid=document.getElementById("userid").value;
var password=document.getElementById("password").value;
var url="./test?userid="+userid+"&password="+password;
var xmlhttp=getAjaxObject();
xmlhttp.open("GET",url,true);
xmlhttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded; charset=UTF-8");
xmlhttp.send(null);
xmlhttp.onreadystatechange=function(){
if(xmlhttp.readyState==4&&xmlhttp.status==200){
document.write(xmlhttp.responseText)
}
};
}









==
public String execute(){
String str="{\"userid\":\""+userid+"\",\"password\":\""+password+"\"}";
result=str;
return SUCCESS;
}

怎么得到的结果是："{\"userid\":\"123456\",\"password\":\"123456\"}"
会是带引号和转义字符的?

简单一点的方法就是不通过struts的返回类型,直接用response写就可以,代码如下：
HttpServletResponse response=ServletActionContext.getResponse();
response.setContentType("text/html;charset=utf-8");
//response.setCharacterEncoding("UTF-8");
PrintWriter out = response.getWriter();
String jsonString="{\"user\":{\"id\":\"123\",\"name\":\"张三\",\"say\":\"Hello , i am a action to print a json!\",\"password\":\"JSON\"},\"success\":true}";
out.println(jsonString);
out.flush();
out.close();
打字不易,如满意,望采纳.
