大致分為三大步：1：生成證書  2：properties檔案配置  3：設定http自動跳轉https

第二步：把證書放在rescurces檔案下，並在properties檔案中配置ssl

#你生成的證書在專案中的位置
server.ssl.key-store=classpath:server.keystore
#建立證書時的密碼
server.ssl.key-store-password=123456
#證書型別
server.ssl.key-store-type=JKS
#你建立證書時取的別名
server.ssl.keyAlias=server_cert

第三步：http自動跳轉https,在啟動類中注入這個兩個bean

package com.example.demo;

import com.example.demo.core.jpa.repository.BaseRepositoryImpl;
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.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.embedded.EmbeddedServletContainerFactory;
import org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;

@SpringBootApplication
@EnableAutoConfiguration
@EnableJpaRepositories(repositoryBaseClass = BaseRepositoryImpl.class)
public class ShiroApplication {

    static Logger logger = LoggerFactory.getLogger(ShiroApplication.class);

    public static void main(String[] args) {
        SpringApplication.run(ShiroApplication.class, args);
    }

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

    @Bean
    public Connector httpConnector() {
        Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
        connector.setScheme("http");
        connector.setPort(8081);
        connector.setSecure(false);
        connector.setRedirectPort(8443);
        return connector;
    }
}
 

最後在瀏覽器中輸入localhost:8081會自動跳轉到https://localhost:8443
