tomcat配置https（单向认证）+如何使用java请求

一.  创建tomcat证书

 

这里使用JDK自带的keytool工具来生成证书：

 

1. 在jdk的安装目录\bin\keytool.exe下打开keytool.exe

 

 

2. 在命令行中输入以下命令:

keytool -genkeypair -alias "tomcat" -keyalg "RSA" -keystore "g:\tomcat.keystore"  

 

以上命令将生产一对非对称密钥和自我签名的证书g:\tomcat.keystore

注意：“名字与姓氏”应该是域名，输成了姓名，和真正运行的时候域名不符，会出问题

这里我输入的密码是123456,  域名是以tomcat为例,  省市以广东深圳为例

 

二. 配置tomcat服务器

 

 定位到tomcat服务器的安装目录, 找到conf下的server.xml文件

填写一个新增一个Connector，如下图

三. 配置javaWeb（可不加，配置成http和https共存）

在web.xml里，加上

 

 

 

SSL 

/* 

 

 

CONFIDENTIAL 

 

 

 

四. java请求跳过证书验证

在普通的http请求代码中，两行代码：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.net.URL;

import java.util.List;
import java.util.Map;

import javax.net.ssl.SSLSession;

import net.sf.json.JSONArray;
import net.sf.json.JSONObject;
