<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>



  
    
    
    
	
	
	    
	
	
	
	
  
  
  
  
    
  

 

 

servlet接受AJAX传递过来的参数

package hb.com;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.List;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class GetServletJson extends HttpServlet {

	public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		this.doPost(request, response);
	}

	public void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		System.out.println(request.getParameter("HB"));
		System.out.println(request.getParameter("time"));
		System.out.println(request.getParameter("arr"));
		System.out.println(request.getParameterValues("arr"));
				
	}

}

 

将数组格式的字符串转换为字符串数组

public class Test {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		String ss = "[111, 222, 333, 444]";
		String a[] = ss.replace("[", "").replace("]", "").split(",");
		for(int i = 0 ; i < a.length; i++){
			System.out.println(a[i].replace(" ", ""));
		} 
	}

}
