生成自签名证书

# keytool是安装JDK自带的工具,keysize大小一般取2048就够了,太大影响解析速度。
# validity有效期我直接整了个100年
# 最后得到的文件就是xx.p12,别名取<alias>
# 命令执行过程中会提示要密钥密码,这个要记住,后面SpringBoot要用到
keytool -genkey -alias <alias> -storetype PKCS12 -keyalg RSA -keysize 2048 -keystore ./xx.p12 -validity 36500

项目部署

证书复制

首先复制p12文件至项目根目录

##配置类
目的是让所有的http请求转向https请求

package com.CmJava.configuration;

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;

@Configuration
public class SSLConfig {

	// 我在application.yaml里面写了http: port: 80
    @Value("${http.port}")
    Integer httpPort;

    //正常启用的https端口 如443
    @Value("${server.port}")
    Integer httpsPort;

    @Bean
    public TomcatServletWebServerFactory servletContainer() {
        TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory() {
            @Override
            protected void postProcessContext(Context context) {
                SecurityConstraint constraint = new SecurityConstraint();
                constraint.setUserConstraint("CONFIDENTIAL");
                SecurityCollection collection = new SecurityCollection();
                collection.addPattern("/*");
                constraint.addCollection(collection);
                context.addConstraint(constraint);
            }
        };
        tomcat.addAdditionalTomcatConnectors(httpConnector());
        return tomcat;
    }

    @Bean
    public Connector httpConnector() {
        Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
        connector.setScheme("http");
        //Connector监听的http的端口号
        connector.setPort(80);
        connector.setSecure(false);
        //监听到http的端口号后转向到的https的端口号
        connector.setRedirectPort(443);
        return connector;
    }
}
