JAVA 自制https 证书

SpringBoot2.x配置HTTPS访问,总体上可以分为两大步:一.生成SSL证书;二.配置HTTPS访问。

打开cmd命令窗口

keytool -genkey -alias tomcat -keyalg RSA -keysize 2048 -validity 365 --keystore F:/tomcat.keystore  -keypass 12345678 -storepass 12345678

-alias tomcat (别名,配置文件会用到这个名字)

 

过程如下:提示问题的回答可以任意填写

在F盘生成了tomcat.keystore文件:

查看keystore中证书条目列表

2 配置项目 ,

把证书放入项目跟目录,跟pom.xml 同一级

配置文件

server:
   port: 443
   ssl:
      key-store: tomcat.keystore
      key-store-password: w
      key-store-type: JKS
      key-alias: tomcat

 

然后新建配置类

 

package com.invoice.project.config;

import org.apache.catalina.Context;
import org.apache.catalina.connector.Connector;
import org.apache.coyote.http11.Http11NioProtocol;
import org.apache.tomcat.util.descriptor.web.SecurityCollection;
import org.apache.tomcat.util.descriptor.web.SecurityConstraint;
import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.boot.web.servlet.server.ServletWebServerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Profile;

@Configuration
@Profile("pro") 
public class HttpsConfigure {

    @Bean
    public ServletWebServerFactory servletWebServerFactory() {
        TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory() {
            @Override
            protected void postProcessContext(Context context) {
                SecurityConstraint securityConstraint = new SecurityConstraint();
                securityConstraint.setUserConstraint("CONFIDENTIAL");
                SecurityCollection securityCollection = new SecurityCollection();
                securityCollection.addPattern("/*");
                securityConstraint.addCollection(securityCollection);
                context.addConstraint(securityConstraint);
            }
        };
        factory.addAdditionalTomcatConnectors(redirectConnector());
        return factory;
    }

    private Connector redirectConnector() {
        Connector connector = new Connector(Http11NioProtocol.class.getName());
        connector.setScheme("http");
        connector.setPort(80);
        connector.setSecure(false);
        connector.setRedirectPort(443);
        return connector;
    }
}
