springboot应用支持https实现

一 jdk自带证书生成

        切换到jdk目录下bin目录，执行

        keytool –genkey –alias (别名) –dname “CN=(姓名),OU=(组织单位名称),O=(组织名称),L=(城市名称),ST=(省),C=(国家)” –storetype (密钥仓库类型) –keyalg (生证书的算法名称) –keysize (密钥长度,证书大小) –keystore (指定生成证书的位置和证书名称) –validity (证书有效期，天单位)

列：keytool -genkey –alias lyc –dname “CN=l,OU=SC,O=yd,L=lc,ST=sc,C=CN” –storetype PKCS12 –keyalg RSA –keysize 2048 –keystore keystore.p12 –validity 365

二 配置https协议

springboot+tomcat,增加代码configuration配置项如下：

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.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class TomcatHttpsConfig {

    @Bean
    public Connector connector() {
        Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
        connector.setScheme("http");
        connector.setSecure(false);
        connector.setPort(80);
        connector.setRedirectPort(443);
        return connector;
    }

    @Bean
    public TomcatServletWebServerFactory tomcatServletWebServerFactory(Connector connector) {
        TomcatServletWebServerFactory webServerFactory = 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);
            }
        };
        webServerFactory.addAdditionalTomcatConnectors(connector);
        return webServerFactory;
    }

}

springboot+undertow，增加代码configuration配置项如下：

import io.undertow.Undertow;
import io.undertow.UndertowOptions;
import io.undertow.servlet.api.SecurityConstraint;
import io.undertow.servlet.api.SecurityInfo;
import io.undertow.servlet.api.TransportGuaranteeType;
import io.undertow.servlet.api.WebResourceCollection;
import org.springframework.boot.web.embedded.undertow.UndertowServletWebServerFactory;
import org.springframework.boot.web.servlet.server.ServletWebServerFactory;
import org.springframework.context.annotation.Bean;

public class UndertowHttpsConfig {
    private int httpPort = 80;
    private int httpsPort = 443;

    @Bean
    public ServletWebServerFactory undertowFactory() {
        UndertowServletWebServerFactory undertowFactory = new UndertowServletWebServerFactory();
        undertowFactory.addBuilderCustomizers((Undertow.Builder builder) -> {
            builder.addHttpListener(httpPort, "0.0.0.0");
            // 开启HTTP2
            builder.setServerOption(UndertowOptions.ENABLE_HTTP2, true);
        });
        undertowFactory.addDeploymentInfoCustomizers(deploymentInfo -> {
            // 开启HTTP自动跳转至HTTPS
            deploymentInfo.addSecurityConstraint(new SecurityConstraint()
                    .addWebResourceCollection(new WebResourceCollection().addUrlPattern("/*"))
                    .setTransportGuaranteeType(TransportGuaranteeType.CONFIDENTIAL)
                    .setEmptyRoleSemantic(SecurityInfo.EmptyRoleSemantic.PERMIT))
                    .setConfidentialPortManager(exchange -> httpsPort);
        });
        return undertowFactory;
    }
}

完成以上配置之后，启动项目，访问：https://localhost:443/test/test实现springboot的https协议访问
