SpringBoot 使用okhttp3
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 { @Bean public X509TrustManager x509TrustManager() { return new X509TrustManager() { @Override public void checkClientTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException { } @Override public void checkServerTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException { } @Override public X509Certificate[] getAcceptedIssuers() { return new X509Certificate[0]; } }; } @Bean public 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 */ @Bean public ConnectionPool pool() { return new ConnectionPool(200, 5, TimeUnit.MINUTES); } @Bean public 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：
import java.util.Iterator; import java.util.Map; import okhttp3.FormBody; import okhttp3.MediaType; import okhttp3.OkHttpClient; import okhttp3.Request; import okhttp3.RequestBody; import okhttp3.Response; import org.apache.commons.lang3.exception.ExceptionUtils; import org.slf4j.Logger; import org.slf4j.LoggerFactory; /** * Created by qhong on 2018/7/3 16:55 **/ public class OkHttpUtil{ private static final Logger logger = LoggerFactory.getLogger(OkHttpUtil.class); /** * 根据map获取get请求参数 * @param queries * @return */ public static StringBuffer getQueryString(String url,Map<String,String> queries){ StringBuffer sb = new StringBuffer(url); if (queries != null && queries.keySet().size() > 0) { boolean firstFlag = true; Iterator iterator = queries.entrySet().iterator(); while (iterator.hasNext()) { Map.Entry entry = (Map.Entry<String, String>) iterator.next(); if (firstFlag) { sb.append("?" + entry.getKey() + "=" + entry.getValue()); firstFlag = false; } else { sb.append("&" + entry.getKey() + "=" + entry.getValue()); } } } return sb; } /** * 调用okhttp的newCall方法 * @param request * @return */ private static String execNewCall(Request request){ Response response = null; try { OkHttpClient okHttpClient = SpringUtils.getBean(OkHttpClient.class); response = okHttpClient.newCall(request).execute(); int status = response.code(); if (response.isSuccessful()) { return response.body().string(); } } catch (Exception e) { logger.error("okhttp3 put error >> ex = {}", ExceptionUtils.getStackTrace(e)); } finally { if (response != null) { response.close(); } } return ""; } /** * get * @param url 请求的url * @param queries 请求的参数，在浏览器？后面的数据，没有可以传null * @return */ public static String get(String url, Map<String, String> queries) { StringBuffer sb = getQueryString(url,queries); Request request = new Request.Builder() .url(sb.toString()) .build(); return execNewCall(request); } /** * post * * @param url 请求的url * @param params post form 提交的参数 * @return */ public static String postFormParams(String url, Map<String, String> params) { FormBody.Builder builder = new FormBody.Builder(); //添加参数 if (params != null && params.keySet().size() > 0) { for (String key : params.keySet()) { builder.add(key, params.get(key)); } } Request request = new Request.Builder() .url(url) .post(builder.build()) .build(); return execNewCall(request); } /** * Post请求发送JSON数据....{"name":"zhangsan","pwd":"123456"} * 参数一：请求Url * 参数二：请求的JSON * 参数三：请求回调 */ public static String postJsonParams(String url, String jsonParams) { RequestBody requestBody = RequestBody.create(MediaType.parse("application/json; charset=utf-8"), jsonParams); Request request = new Request.Builder() .url(url) .post(requestBody) .build(); return execNewCall(request); } /** * Post请求发送xml数据.... * 参数一：请求Url * 参数二：请求的xmlString * 参数三：请求回调 */ public static String postXmlParams(String url, String xml) { RequestBody requestBody = RequestBody.create(MediaType.parse("application/xml; charset=utf-8"), xml); Request request = new Request.Builder() .url(url) .post(requestBody) .build(); return execNewCall(request); } }
