Okhttp3系列之(2) - SpringBoot Okhttp3配置工具类

本文主要是介绍Okhttp3系列之(2) - SpringBoot Okhttp3配置工具类，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1.添加pom.xml依赖

<dependency><groupId>com.squareup.okhttp3</groupId><artifactId>okhttp</artifactId><version>3.6.0</version>
</dependency>

2.配置类

import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.security.SecureRandom;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import java.util.concurrent.TimeUnit;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSocketFactory;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import okhttp3.ConnectionPool;
import okhttp3.OkHttpClient;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;/*** Created by qhong on 2018/7/3 16:52**/
@Configuration
public class OkHttpConfig {@Beanpublic X509TrustManager x509TrustManager() {return new X509TrustManager() {@Overridepublic void checkClientTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {}@Overridepublic void checkServerTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {}@Overridepublic X509Certificate[] getAcceptedIssuers() {return new X509Certificate[0];}};}@Beanpublic SSLSocketFactory sslSocketFactory() {try {//信任任何链接SSLContext sslContext = SSLContext.getInstance("TLS");sslContext.init(null, new TrustManager[]{x509TrustManager()}, new SecureRandom());return sslContext.getSocketFactory();} catch (NoSuchAlgorithmException e) {e.printStackTrace();} catch (KeyManagementException e) {e.printStackTrace();}return null;}/*** Create a new connection pool with tuning parameters appropriate for a single-user application.* The tuning parameters in this pool are subject to change in future OkHttp releases. Currently*/@Beanpublic ConnectionPool pool() {return new ConnectionPool(200, 5, TimeUnit.MINUTES);}@Beanpublic OkHttpClient okHttpClient() {return new OkHttpClient.Builder().sslSocketFactory(sslSocketFactory(), x509TrustManager()).retryOnConnectionFailure(false)//是否开启缓存.connectionPool(pool())//连接池.connectTimeout(10L, TimeUnit.SECONDS).readTimeout(10L, TimeUnit.SECONDS).build();}
}

3.工具类：
