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;

@Configuration
public class WebConfig {
@Bean
public 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
@Bean
public 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;
}
}
