servlet层中的代码如下：
package com.swift.jztk.servlet;import java.io.IOException;import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;import com.swift.jztk.biz.IQuestionBiz;
import com.swift.jztk.biz.QuestionBizImpl;@WebServlet("/getQuestions")
public class GetQuestions extends HttpServlet {private static final long serialVersionUID = 1L;IQuestionBiz biz = new QuestionBizImpl();public GetQuestions() {super();}protected void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {response.getWriter().append("Served at: ").append(request.getContextPath());String testType = request.getParameter("testType");String json = biz.getQuestions(testType);response.getWriter().println(json);}protected void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {doGet(request, response);}}在get方法中增加设置服务器端和浏览器端的代码解析方式为utf-8
response.setCharacterEncoding("utf-8");response.setContentType("text/html;charset=utf-8");
成功解决
