springBoot发布https服务及调用

article 2024/12/31 3:40:57

一、服务端发布https服务

1、准备SSL证书

（1）自签名证书：如果你只是用于开发或测试环境，可以生成一个自签名证书。
（2）CA 签名证书：对于生产环境，应该使用由受信任的证书颁发机构 (CA) 签名的证书。

这里采用生成自签名证书，可以使用keytool工具生成自签名证书（jdk工具）：

keytool -genkeypair -alias myapp -keyalg RSA -keysize 2048 -storetype PKCS12 -keystore keystore.p12 -validity 3650

这将创建一个有效期为 10 年的自签名证书，并将其存储在 keystore.p12 文件中。你需要提供一些信息，如组织名称等。注意记住密码和别名。

如下图：

2、配置springboot启用HTTPS并指定SSL证书的位置和密码

用application.properties 或 application.yml都可以。这样配置可以读取环境变量

把证书放在resource的ssl目录下

server:
  port: 8443
  ssl:
    enabled: ${SSL_ENABLED:true}
    key-store: ${SSL_KEY_STORE:classpath:ssl/keystore.p12}
    key-store-password: ${SSL_KEY_STORE_PASSWORD:myapptest}
    keyStoreType: ${SSL_KEY_STORE_TYPE:PKCS12}
    keyAlias: ${SSL_KEY_ALIAS:myapp}

启动服务即可通过https访问了，默认可以设置成false

3、配置docker容器，启动https

把证书放在ssl目录下

version: "3"
services:
 
  test-https:
    image: openjdk:8-jdk
    container_name: test-https
    restart: always
    ports:
      - 22443:22443
    command: java -jar /opt/test-https.jar
    volumes:
      - /home/services/test/:/opt/
      - /home/services/test/config/:/config/
      - /home/services/test/ssl/:/ssl/
      - /home/services/test/template_server/:/template_server/
      - /home/services/test/patch/:/patch/
      - /home/log/test/:/logs/
    environment:
      - TZ=Asia/Shanghai
      - SERVICE_HOST=${HOST_IP}
      - server.port=22443
      - NACOS_NAMESPACE=${NACOS_NAMESPACE}
      - NACOS_ADDR=${NACOS_ADDR}
       #开启https,如果不开启则配置为false
      - SSL_ENABLED=true
      #以下配置根据实际证书配置
      - SSL_KEY_STORE=ssl/keystore.p12
      - SSL_KEY_STORE_PASSWORD=myapptest
      - SSL_KEY_STORE_TYPE=PKCS12
      - SSL_KEY_ALIAS=myapp
      - JAVA_OPTS=-Xmx512m -XX:G1ConcRefinementThreads=4 -XX:MaxDirectMemorySize=1G

二、通过httpinvoke方法https服务

跳过证书校验

public class HttpInvokerRequestExecutorWithSession extends SimpleHttpInvokerRequestExecutor {

	private int connectTimeout=0;

	private int readTimeout=0;


	private SSLContext sslContext;
	private HostnameVerifier hostnameVerifier;

	private void initSsl() {
		try {
			sslContext = SSLContext.getInstance("TLS");
			sslContext.init(null, new TrustManager[]{new X509TrustManager() {
				public java.security.cert.X509Certificate[] getAcceptedIssuers() {
					return null;
				}
				public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType) {}
				public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType) {}
			}}, new SecureRandom());
		} catch (KeyManagementException | NoSuchAlgorithmException e) {
			logger.error("ssl init error:",e);
			throw new MsrRuntimeException(e.getMessage());
		}
		hostnameVerifier = (hostname, session) -> true;
	}

	/**
	 *
	 * (non-Javadoc)
	 *
	 * @see org.springframework.remoting.httpinvoker.SimpleHttpInvokerRequestExecutor
	 *      #prepareConnection(java.net.HttpURLConnection, int)
	 */
	protected void prepareConnection(HttpURLConnection con, int contentLength) throws IOException {
		super.prepareConnection(con, contentLength);
		if (con instanceof HttpsURLConnection) {
			if (sslContext == null) {
				initSsl();
			}
			((HttpsURLConnection) con).setSSLSocketFactory(sslContext.getSocketFactory());
			((HttpsURLConnection) con).setHostnameVerifier(hostnameVerifier);
		}
		con.setConnectTimeout(connectTimeout);
		con.setReadTimeout(readTimeout);

	}

	/**
	 *
	 * (non-Javadoc)
	 *
	 * @see org.springframework.remoting.httpinvoker.SimpleHttpInvokerRequestExecutor
	 *      #validateResponse(org.springframework.remoting.httpinvoker.HttpInvokerClientConfiguration,
	 *      java.net.HttpURLConnection)
	 */
	protected void validateResponse(HttpInvokerClientConfiguration config, HttpURLConnection con)
			throws IOException {
		super.validateResponse(config, con);
	}

	public int getConnectTimeout() {
		return connectTimeout;
	}

	public void setConnectTimeout(int connectTimeout) {
		this.connectTimeout = connectTimeout;
	}

	public int getReadTimeout() {
		return readTimeout;
	}

	public void setReadTimeout(int readTimeout) {
		this.readTimeout = readTimeout;
	}

}

三、feign接口调用https服务

跳过证书校验。feign接口的地址还是正常配置http或https都支持

import feign.Client;
import feign.Contract;
import feign.RequestInterceptor;
import feign.codec.ErrorDecoder;
import feign.jaxrs.JAXRSContract;
import okhttp3.ConnectionPool;
import okhttp3.OkHttpClient;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSocketFactory;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import java.security.SecureRandom;
import java.security.cert.X509Certificate;
import java.util.concurrent.TimeUnit;

@Configuration
public class FeignConfiguration {

    @Autowired
    private BusinessConfig businessConfig;

    /**
     * yaml中的配置未生效，暂时在配置类中配置
     */
    @Bean
    public Contract getFeignContract() {
        return new JAXRSContract();
    }

    @Bean
    public ErrorDecoder getFeignErrorDecoder() {
        return new FeignExceptionDecoder();
    }

    @Bean
    public OkHttpClient okHttpClient() {
        if(businessConfig.getRootServiceUrl() != null && businessConfig.getRootServiceUrl().contains("https")){
            try {
                TrustManager[] trustManagers = getTrustManager();
                if (trustManagers == null || trustManagers.length == 0) {
                    throw new IllegalStateException("Failed to create trust managers");
                }

                SSLSocketFactory sslSocketFactory = getSSLSocketFactory();
                if (sslSocketFactory == null) {
                    throw new IllegalStateException("Failed to initialize SSL socket factory");
                }

                return new OkHttpClient.Builder()
                        .readTimeout(60, TimeUnit.SECONDS)
                        .connectTimeout(60, TimeUnit.SECONDS)
                        .writeTimeout(120, TimeUnit.SECONDS)
                        .connectionPool(new ConnectionPool())
                        .sslSocketFactory(sslSocketFactory, (X509TrustManager) trustManagers[0])
                        .hostnameVerifier((hostname, session) -> true)
                        .build();
            } catch (Exception e) {
                throw new RuntimeException("Failed to create OkHttpClient", e);
            }
        }
        return new OkHttpClient.Builder()
                .readTimeout(60, TimeUnit.SECONDS)
                .connectTimeout(60, TimeUnit.SECONDS)
                .writeTimeout(120, TimeUnit.SECONDS)
                .connectionPool(new ConnectionPool())
                .build();
    }

    @Bean
    public RequestInterceptor requestInterceptor() {
        return new CustomRequestInterceptor(businessConfig);
    }

    @Bean
    public Client feignClient(OkHttpClient okHttpClient) {
        return new CustomClient(new feign.okhttp.OkHttpClient(okHttpClient));
    }

    private TrustManager[] getTrustManager() {
        try {
            TrustManager[] trustAllCerts = new TrustManager[]{
                    new X509TrustManager() {
                        public X509Certificate[] getAcceptedIssuers() {
                            return new X509Certificate[0];
                        }
                        public void checkClientTrusted(X509Certificate[] certs, String authType) {}
                        public void checkServerTrusted(X509Certificate[] certs, String authType) {}
                    }
            };
            return trustAllCerts;
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

    private SSLSocketFactory getSSLSocketFactory() {
        try {
            SSLContext sc = SSLContext.getInstance("TLS");
            sc.init(null, getTrustManager(), new SecureRandom());
            return sc.getSocketFactory();
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

}
