在springboot中配置https安装证书 Unable to Start embedded TomCat

首先要获得http证书，可以向证书机构申请也可以自己制作根证书。在我当初配置https时一直报Unable to Start embedded TomCat的错误，后来仔细检查发现因为证书没和jar包放在一个根目录。然后添加如下代码设置证书配置即可

代码如下：

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.boot.context.embedded.ConfigurableEmbeddedServletContainer;import org.springframework.boot.context.embedded.EmbeddedServletContainerCustomizer;import org.springframework.boot.context.embedded.EmbeddedServletContainerFactory;import org.springframework.boot.context.embedded.Ssl;import org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;@Configurationpublic class WebConfig {@Beanpublic EmbeddedServletContainerCustomizer containerCustomizer() {    return new EmbeddedServletContainerCustomizer() {        @Override        public void customize(ConfigurableEmbeddedServletContainer container) {            Ssl ssl = new Ssl();            //Server.jks中包含服务器私钥和证书            ssl.setKeyStore("证书名");            ssl.setKeyStorePassword("密码");            container.setSsl(ssl);            container.setPort(443);        }    };}//将http重定向至https@Beanpublic EmbeddedServletContainerFactory servletContainerFactory() {    TomcatEmbeddedServletContainerFactory factory =        new TomcatEmbeddedServletContainerFactory() {            @Override            protected void postProcessContext(Context context) {                //SecurityConstraint必须存在，可以通过其为不同的URL设置不同的重定向策略。                SecurityConstraint securityConstraint = new SecurityConstraint();                securityConstraint.setUserConstraint("CONFIDENTIAL");                SecurityCollection collection = new SecurityCollection();                collection.addPattern("/*");                securityConstraint.addCollection(collection);                context.addConstraint(securityConstraint);            }        };    factory.addAdditionalTomcatConnectors(createHttpConnector());    return factory;}private Connector createHttpConnector() {    Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");    connector.setScheme("http");    connector.setSecure(false);    connector.setPort(80);    connector.setRedirectPort(443);    return connector;}}
