JSON数据的中文乱码问题

在　PrintWriter out = response.getWriter();　

语句前使用

response.setContentType("text/json; charset=utf-8");

response.setCharacterEncoding("utf-8");

 

 

添加后代码如下：

XXXAction.java :

    String json = "{totalProperty:" + this.getTotalProperty() + ", start:"  
                    + this.getStart() + ", limit:" + this.getLimit() + ", root:"  
                    + listStudent.toString() + "}";  
    this.getResponse().setContentType("text/json; charset=utf-8");  
    this.getResponse().setCharacterEncoding("utf-8");   
    super.outPrint(json);       
    System.out.println(json);  // 打印出来看看效果  
    super.setContentType(BaseAction.JSON);
