一、背景介绍
某个供应商服务需要部署到海外，如果海外多个地区需要部署多个服务，最好能实现统一登录，这样可以减轻用户的使用负担（不用记录一堆密码）。由于安全问题（可能会泄露用户数据），海外服务不能直连公司sso服务端，因此需要其他的方案解决安全问题。最终的安全方案中需要用到SSL双向认证进行数据的传输和交互，并且只指定某些个别接口实现SSL双向认证。在此背景下，这篇文章介绍基于tomcat的SSL双向认证的简单实现。
二、SSL简单介绍
SSL(Secure Sockets Layer 安全套接层)就是一种协议（规范），用于保障客户端和服务器端通信的安全，以免通信时传输的信息被窃取或者修改。
1.怎样保障数据传输安全？
客户端和服务器端在进行握手（客户端和服务器建立连接和交换参数的过程称之为握手）时会产生一个"对话密钥"（session key），用来加密接下来的数据传输，解密时也是用的这个"对话密钥"，而这个"对话密钥"只有客户端和服务器端知道。也就是说只要这个"对话密钥"不被破解，就能保证安全。
2. 客户端证书和服务器端证书
客户端证书和服务器端证书用于证明自己的身份，就好比每个人都有一张身份证，这种身份证是唯一的。一般来说，只要有服务器端的证书就可以了，但是有时需要客户端提供自己的证书，已证明其身份。
三、生成自签名的服务器端证书和导入服务器端信任证书库
一般证书可以使用权威机构颁发的证书，如：veri sign，百度使用的就是veri sign颁发的证书，这样的权威证书机构是受信任的，但是这些机构颁发的证书往往是需要收费的，这样的证书也难得到。对于小型企业来说为了节约成本，常常使用自签名的证书。
接下来使用JDK keytool工具来签发证书，如果未安装JDK，请先安装JDK（本文使用的是JDK8）。本文所有的证书文件都放到/cert/test1(操作系统centos)，您可以选择一个目录来存放。
1.制作服务端密钥库
keytool -genkey -v -alias server -keyalg RSA
-keystore /cert/test1/server.keystore -validity 36500
-ext SAN=dns:test-ssl,ip:10.1.x.x
-dname "CN=test,OU=test,O=test,L=hz,ST=hz,C=cn"
注意：SAN填写的是域名，IP填写是服务端IP。SAN和IP是解决谷歌浏览器证书无效的关键。
2.制作客户端密钥库
keytool -genkey -v -alias client -keyalg RSA -storetype PKCS12
-keystore /cert/test1/client.p12 -dname "CN=test,OU=test,O=test,L=hz,ST=hz,C=cn"
3.客户端证书导入服务端密钥库
由于不能直接将p12导入，需要先从客户端密钥库导出证书，再将导出的证书导入服务端密钥库。
keytool -export -alias client -keystore /cert/test1/client.p12
-storetype PKCS12 -storepass 123456 -rfc -file /cert/test1/client.cer
keytool -import -v -file /cert/test1/client.cer -keystore /cert/test1/server.keystore
4.导出服务端密钥库证书
keytool -keystore /cert/test1/server.keystore -export -alias server -file /cert/test1/server.cer
5.配置tomcat
5.1配置server.xml
找到conf目录下的server.xml文件，增加如下配置。
<Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol"
SSLEnabled="true"maxThreads="150" scheme="https" secure="true"
clientAuth="true" sslProtocol="TLS"
keystoreFile="/cert/test1/server.keystore" keystorePass="123456"
truststoreFile ="/cert/test1/server.keystore" truststorePass="123456"
/>
说明：
- clientAuth为true表示开启SSL双向认证
- keystoreFile指定服务器端的证书位置
- truststoreFile指定服务器端信任证书库
5.2配置web.xml
找到conf目录下的server.xml文件，增加如下配置。
<security-constraint>
<web-resource-collection>
<web-resource-name>SSL</web-resource-name>
<url-pattern>/ssl_test/*</url-pattern>
</web-resource-collection>
<user-data-constraint>
<description>SSL required</description>
<transport-guarantee>CONFIDENTIAL</transport-guarantee>
</user-data-constraint>
</security-constraint>
说明：
- 如果不加入这个配置，那么所有访问的地址都必须要使用SSL才能访问，有时我们可能只需要通过某个或者某些SSL地址获取客户端证书来认证用户身份，认证成功后不需要使用SSL来进行访问（可以配置多个security-constraint）
- url-pattern：指定需要SSL才能进行访问的地址(/ssl_test/*)
- transport-guarantee：合法值为NONE、 INTEGRAL或CONFIDENTIAL，transport-guarantee为NONE值将对所用的通讯协议不加限制。INTEGRAL值表示数据必须以一种防止截取它的人阅读它的方式传送。虽然原理上（并且在未来的HTTP版本中），在 INTEGRAL和CONFIDENTIAL之间可能会有差别，但在当前实践中，他们都只是简单地要求用SSL
- 创建SSLServlet获取客户端证书
6.编写用来获取客户端证书的filter及测试接口类
客户端证书验证拦截器(拦截路径：/ssl_test/*)
java
package com.example.demo;
import java.io.IOException;
import java.security.cert.X509Certificate;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.annotation.WebFilter;
/**

* @create: 2024-02-02 10:55
*/
@WebFilter(urlPatterns = "/ssl_test/*")
public class MyFilter implements Filter {
private static final String REQUEST_ATTR_CERT = "javax.servlet.request.X509Certificate";
private static final String SCHEME_HTTPS = "https";
/**
* web应用启动时，web服务器将创建Filter的实例对象，并调用init方法，读取web.xml的配置，完成对象的初始化功能，
* 从而为后续的用户请求做好拦截的准备工作（filter对象只会创建一次，init方法也只会执行一次，开发人员通过init的参数，
* 可或得代表当前filter配置信息的FilterConfig对象）
* @param filterConfig
* @throws ServletException
*/
@Override
public void init(FilterConfig filterConfig) throws ServletException {
}
/**
* 这个方法完成实际的过滤操作，当客户请求访问与过滤器相关联的URL的时候，Servlet过滤器将先执行doFilter方法，FilterChain参数用于访问后续过滤器
* @param request
* @param response
* @param filterChain
* @throws IOException
* @throws ServletException
*/
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain)
throws IOException, ServletException {
X509Certificate[] certs = (X509Certificate[]) request.getAttribute(REQUEST_ATTR_CERT);
if (certs != null) {
int count = certs.length;
System.out.println("共检测到[" + count + "]个客户端证书");
for (int i = 0; i < count; i++) {
X509Certificate cert = certs[i];
System.out.println("客户端证书 [" + cert.getSubjectDN() + "]： ");
System.out.println("证书是否有效：" + (verifyCertificate(cert) ? "是" : "否"));
System.out.println("证书详细信息：\r" + cert.toString());
}
filterChain.doFilter(request, response);
} else {
if (SCHEME_HTTPS.equalsIgnoreCase(request.getScheme())) {
System.out.println("这是一个HTTPS请求，但是没有可用的客户端证书");
} else {
System.out.println("这不是一个HTTPS请求，因此无法获得客户端证书列表 ");
}
}
System.out.println("我是过滤器，我进来了");
}
/**
* filter创建后会保存在内存中，当web应用移除或者服务器停止时才销毁，该方法在Filter的生命周期中仅执行一次，在这个方法中，可以释放过滤器使用的资源
*/
@Override
public void destroy() {
}
/**
*
* 校验证书是否过期
*
*
* @param certificate
* @return
*/
private boolean verifyCertificate(X509Certificate certificate) {
boolean valid = true;
try {
certificate.checkValidity();
} catch (Exception e) {
e.printStackTrace();
valid = false;
}
return valid;
}
}启动类（服务部署到tomcat）

客户端ssl证书认证接口

import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/ssl_test")
public class SSLTestController {
@GetMapping("/hello")
public String auth() {
return "Hello, I am the server! Your client's SSL certificate has been authenticated!";
}
}不需要认证客户端证书的接口
java
package com.example.demo;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**

@GetMapping("/hello")
public String auth() {
return "Hello, I am the server!";
}
}7.测试
7.1 浏览器访问测试
7.1.1ssl双向认证测试
用浏览器访问http://10.1.x.x:8080/test/no_ssl_test/hello
细心的读者可能发现链接已经跳转到了 https://10.1.x.x:8443/test/ssl_test/hello，这是由于这个地址被设置为需要SSL才能访问，所以跳转到了这个地址。访问时页面提示如下：
为了不出现这样的警告信息，我们可以导入服务器端证书到客户端，双击服务端证书
选择当前用户
将证书放入可信任的根证书列表 ，随后安装成功
再次访问： http://10.1.x.x:8080/test/ssl_test/hello,出现如下错误
由于我们访问的接口是双向认证，所以也需要客户端的证书，我们接下来导入客户端证书
自动选择证书存储
输入证书密钥，随即安装成功
第三次访问： http://10.1.x.x:8080/test/ssl_test/hello，结果如下所示
需要选择客户端证书
输出结果如下
tomcat 日志如下，（证书是否有效：是）表示客户端证书已经通过服务端验证
7.1.2 不验证客户端证书
访问地址http://10.1.x.x:8080/test/no_ssl_test/hello， 发现没有跳转到8443端口，正常返回内容如下
7.2 测试java通过httpclient调用双向认证接口
1.增加apache httpclient依赖
<!-- https://mvnrepository.com/artifact/org.apache.httpcomponents/httpcore -->
