【Https】Spring RestTemplete支持Https安全请求
2024-09-01 06:19:37
实现步骤
Step1: 自定义ClientHttpRequestFactory
package com.example.demo.https;
import org.springframework.http.client.SimpleClientHttpRequestFactory;
import javax.net.ssl.*;
import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.InetAddress;
import java.net.Socket;
import java.security.cert.X509Certificate;
/**
* Desc: 使用Spring RestTemplete实现 Https需要自定义ClientHttpRequestFactory；
* <p>
* 参考链接：https://stackoverflow.com/questions/17619871/access-https-rest-service-using-spring-resttemplate
*/
public class HttpsClientRequestFactory extends SimpleClientHttpRequestFactory {
@Override
protected void prepareConnection(HttpURLConnection connection, String httpMethod) {
try {
if (!(connection instanceof HttpsURLConnection)) {
throw new RuntimeException("An instance of HttpsURLConnection is expected");
}
HttpsURLConnection httpsConnection = (HttpsURLConnection) connection;
TrustManager[] trustAllCerts = new TrustManager[]{
new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}
public void checkClientTrusted(X509Certificate[] certs, String authType) {
}
public void checkServerTrusted(X509Certificate[] certs, String authType) {
}
}
};
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
httpsConnection.setSSLSocketFactory(new MyCustomSSLSocketFactory(sslContext.getSocketFactory()));
httpsConnection.setHostnameVerifier(new HostnameVerifier() {
@Override
public boolean verify(String s, SSLSession sslSession) {
return true;
}
});
super.prepareConnection(httpsConnection, httpMethod);
} catch (Exception e) {
e.printStackTrace();
}
}
/**
* We need to invoke sslSocket.setEnabledProtocols(new String[] {"SSLv3"});
* see http://www.oracle.com/technetwork/java/javase/documentation/cve-2014-3566-2342133.html (Java 8 section)
*/
private static class MyCustomSSLSocketFactory extends SSLSocketFactory {
private final SSLSocketFactory delegate;
public MyCustomSSLSocketFactory(SSLSocketFactory delegate) {
this.delegate = delegate;
}
@Override
public String[] getDefaultCipherSuites() {
return delegate.getDefaultCipherSuites();
}
@Override
public String[] getSupportedCipherSuites() {
return delegate.getSupportedCipherSuites();
}
@Override
public Socket createSocket(final Socket socket, final String host, final int port, final boolean autoClose) throws IOException {
final Socket underlyingSocket = delegate.createSocket(socket, host, port, autoClose);
return overrideProtocol(underlyingSocket);
}
@Override
public Socket createSocket(final String host, final int port) throws IOException {
final Socket underlyingSocket = delegate.createSocket(host, port);
return overrideProtocol(underlyingSocket);
}
@Override
public Socket createSocket(final String host, final int port, final InetAddress localAddress, final int localPort) throws
IOException {
final Socket underlyingSocket = delegate.createSocket(host, port, localAddress, localPort);
return overrideProtocol(underlyingSocket);
}
@Override
public Socket createSocket(final InetAddress host, final int port) throws IOException {
final Socket underlyingSocket = delegate.createSocket(host, port);
return overrideProtocol(underlyingSocket);
}
@Override
public Socket createSocket(final InetAddress host, final int port, final InetAddress localAddress, final int localPort) throws
IOException {
final Socket underlyingSocket = delegate.createSocket(host, port, localAddress, localPort);
return overrideProtocol(underlyingSocket);
}
private Socket overrideProtocol(final Socket socket) {
if (!(socket instanceof SSLSocket)) {
throw new RuntimeException("An instance of SSLSocket is expected");
}
((SSLSocket) socket).setEnabledProtocols(new String[]{"TLSv1"});
return socket;
}
}
}
Step2: 设置RestTemplate的RequestFactory
package com.example.demo.https;
import org.springframework.web.client.RestTemplate;
/**
* Desc: 参考链接：https://stackoverflow.com/questions/17619871/access-https-rest-service-using-spring-resttemplate
*/
public class RestTempleteConfig {
private RestTemplate httpRestTemplate;
private RestTemplate httpsRestTemplate;
public void init() {
this.httpsRestTemplate = new RestTemplate(new HttpsClientRequestFactory());
this.httpRestTemplate = new RestTemplate();
}
}
