当进行了action后转至get，这个sevlet进行接受参数处理

get.java

import java.io.IOException;import java.io.PrintWriter;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;public class get extends HttpServlet {public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {response.setContentType("text/html;charset=gb2312");PrintWriter out = response.getWriter();String username=request.getParameter("username");String password=request.getParameter("password");String usersex=request.getParameter("usersex");String year=request.getParameter("year");String month=request.getParameter("month");String day=request.getParameter("day");String[] aihao=request.getParameterValues("aihao");String[]xingge=request.getParameterValues("xingge");String beizhu=request.getParameter("beizhu");//输出就只对多选的部分写出代码，其他直接out.print(username);等即可out.println("爱好");for(int i=0;i<aihao.length;i++){out.println(aihao[i]);}out.println("性格");for(int i=0;i<xingge.length;i++){out.println(xingge[i]);}}}
