1、SpringBoot项目如何部署SSL证书 (JKS格式)



1. 获取 SSL 证书和私钥

首先,你需要获取有效的 SSL 证书和私钥。SSL 证书是一种用于加密通信的数字证书,它可以通过购买商业 SSL 证书或使用免费的 Let’s Encrypt 证书获得。请确保你拥有证书文件和与之对应的私钥文件,这通常是以 .pem 和 .key 结尾的文件或者是jks格式的,本文以jks格式的SSL证书为例。



2. 配置 Spring Boot 项目

接下来,我们将配置 Spring Boot 项目以使用 SSL。



2.0 项目环境

spring boot 2.2.2

maven

一个域名(各大域名商有售,阿里、腾讯、华为)

SSL证书(阿里云上有免费的SSL证书,有效期一年)



2.1 将 SSL 证书和私钥文件添加到项目

将之前获取的 SSL 证书和私钥文件拷贝到 Spring Boot 项目中的 src/main/resources 目录下。这样,证书文件会与项目一起打包并在运行时加载。

2.2 配置 application.properties 或 application.yml

在 Spring Boot 项目的配置文件(application.properties 或 application.yml)中添加以下 SSL 相关配置:

server:
  port: 8856
  servlet:
    context-path: /
  ssl:
    enabled: true
    # 保存SSL证书的秘钥库的路径
    key-store: classpath:ssl/xxx.com.jks
    key-store-password: xxx
    # 证书类型
    key-store-type: JKS
#    key-store-protocol: TLS



2.3 编写controller进行测试

添加一个controller,测试是否生效,测试结果如下:

通过上述访问发现,如果通过http访问会提示访问需要组合TLS,但是如果用户直接通过这种方式访问的话,存在着极差的用户体验。



2.4 编写配置类HTTP转HTPPS

当用户使用http访问的时候,将http协议重定向到https端口

(1)修改配置文件

custom:  # 自定义http启动端口
  http-port: 8857

server:
  port: 8856
  servlet:
    context-path: /
  ssl:
    enabled: true
    #key-alias: alias-key # 别名(可以不进行配置)
    # 保存SSL证书的秘钥库的路径
    key-store: classpath:ssl/xxx.com.jks
    key-store-password: xxx
    # 证书类型
    key-store-type: JKS
#    key-store-protocol: TLS

(2)添加配置类

package org.pp.ssl.config;

import org.apache.catalina.Context;
import org.apache.catalina.connector.Connector;
import org.apache.tomcat.util.descriptor.web.SecurityCollection;
import org.apache.tomcat.util.descriptor.web.SecurityConstraint;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * https配置,将http请求全部转发到https
 * @author P_P
 */
@Configuration
public class HttpsConfig {

    @Value("${custom.http-port: 8857}")
    private Integer httpPort;

    @Value("${server.port}")
    private Integer port;

    @Bean
    public TomcatServletWebServerFactory servletContainer() {
        // 将http请求转换为https请求
        TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory() {
            @Override
            protected void postProcessContext(Context context) {
                SecurityConstraint constraint = new SecurityConstraint();
                // 默认为NONE
                constraint.setUserConstraint("CONFIDENTIAL");
                SecurityCollection collection = new SecurityCollection();
                // 所有的东西都https
                collection.addPattern("/*");
                constraint.addCollection(collection);
                context.addConstraint(constraint);
            }
        };
        tomcat.addAdditionalTomcatConnectors(httpConnector());
        return tomcat;
    }

    /**
     * 强制将所有的http请求转发到https
     *
     * @return httpConnector
     */
    @Bean
    public Connector httpConnector() {
        Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
        connector.setScheme("http");
        // connector监听的http端口号
        connector.setPort(httpPort);
        connector.setSecure(false);
        // 监听到http的端口号后转向到的https的端口号
        connector.setRedirectPort(port);
        return connector;
    }
}

(3)启动项目

添加配置类之后,启动项目可以看到控制台出现了https端口和http端口

再次访问测试接口,会发现地址栏出现了https

(4)同时开启http和https

如果不想将http请求都转发到https进行处理,可以同时开启http和https

/**
 * 同时开启http和https
 * @author P_P
 */
import org.apache.catalina.connector.Connector;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class HttpsConfig {
    @Value("${custom.http-port: 8857}")
    private Integer httpPort;

    @Bean
    public TomcatServletWebServerFactory servletContainer() {
        TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory();
        tomcat.addAdditionalTomcatConnectors(httpConnector());
        return tomcat;
    }

    @Bean
    public Connector httpConnector() {
        Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
        connector.setPort(httpPort);
        return connector;
    }
}

这样访问8857(http协议)的端口就不会进行转发了

3、spring boot配置ssl证书,异常:Invalid keystore format



3.1环境介绍

springBoot中配置了一个bean,bean加载的时候,会进行jks的加载,jks文件放在src/resources下,然后就报错了,错误如下。

3.2现象及原因分析

直接用main函数解析jks文件,一点毛病都没有。但是打包后启动Tomact再解析就不行,直接启动单元测试(完整加载bean的形式)也不行。

后来发现,在target文件夹下,jks文件的大小变了。查了资料,大概明白错误的根本原因了:maven编译或者打包的时候,对文件的内容进行了修改(maven编译的时候使用了占位符,替换的时候使文件发生了变化),这就导致了jks文件发生变化。



3.3解决方案

配置MAVEN过滤JKS等格式的文件,在pom的build配置中增加如下过滤配置,将jks过滤掉。(提一句,以下配置中也过滤了xlsx,是因为打包后Excel文件也会坏掉)

<build>
