Springboot项目使用https

1 配置https

1.1 打开cmd，输入生成证书的命令

keytool -genkey -alias tomcat  -storetype PKCS12 -keyalg RSA -keysize 2048  -keystore keystore.p12 -validity 3650

　　参数含义:

　　1.-storetype 指定密钥仓库类型
　　2.-keyalg 生证书的算法名称，RSA是一种非对称加密算法
　　3.-keysize 证书大小
　　4.-keystore 生成的证书文件的存储路径
　　5.-validity 证书的有效期

1.2 输入密钥库口令(后面需要写入springboot文件中)

1.3 依次填写证书相关的信息(随便填写即可)

1.4 将生成证书放置在项目路径下

1.5 启动项目

2 http重定向到https

在配置类中添加如下method

@Bean
public EmbeddedServletContainerFactory tomcatEmbeddedServletContainerFactory() {
	final TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory();
	factory.addAdditionalTomcatConnectors(this.createConnection());
	return factory;
}

private Connector createConnection() {
	final String protocol = "org.apache.coyote.http11.Http11NioProtocol";
	final Connector connector = new Connector(protocol);

	connector.setScheme("http");
	connector.setPort(8080);// http端口
	connector.setRedirectPort(443);// https端口
	return connector;
}

2.1 请求结果

 重定向成功,哈哈

注意事项:

1. 使用postman 访问注意问题(关闭ssl证书校验)

2. Springboot项目启动报错, DerInputStream.getLength(): lengthTag=111, too big.

该错误产生是因为maven的resouce过滤破坏了.p12文件,通过在pom文件中添加配置即可

<resources>
            <resource>

                <filtering>true</filtering>
                <excludes>
                    <exclude>**/*.p12</exclude>
                </excludes>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <filtering>false</filtering>
                <includes>
                    <include>**/*.p12</include>
                </includes>
            </resource>
</resources>
