客户端显示json的问题。

服务器返回json类型的数据给客户端，客户端接收的数据returnedData，通过returnedData.key得不到json数据相应key的值。请各位路过的帮小女子看一下这个问题出在哪里了，是在是找不出来了 。

{
 private String name;
public String getName()
{
    return name;
}
public void setName(String name)
{
    this.name = name;
}

@Override
public String execute() throws Exception
{
    People people = new People();

    people.setId(1);
    people.setName(name);
    people.setAge(30);
    people.setAddress("beijing");


    HttpServletResponse response = ServletActionContext.getResponse();

    Gson gson = new Gson();

    String result = gson.toJson(people);
    System.out.println(result);

    response.setHeader("pragma","no-cache");
    response.setHeader("cache-control", "no-cache");
    response.setContentType("application/json");

    PrintWriter out = response.getWriter();

    out.println(result);
   return null;
}
}
