1. Maven 添加依赖
<dependency>
<groupId>com.squareup.okhttp3</groupId>
<artifactId>okhttp</artifactId>
<version>3.10.0</version>
</dependency>
2. application.properties 配置文件
ok.http.connect-timeout=30
ok.http.read-timeout=30
ok.http.write-timeout=30
# 连接池中整体的空闲连接的最大数量
ok.http.max-idle-connections=200
# 连接空闲时间最多为 300 秒
ok.http.keep-alive-duration=300
3. OkHttpConfiguration 配置类
import okhttp3.ConnectionPool;
import okhttp3.OkHttpClient;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import javax.net.ssl.*;
import java.security.*;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import java.util.concurrent.TimeUnit;

@Configuration

private Integer writeTimeout;
@Value("${ok.http.max-idle-connections}")
private Integer maxIdleConnections;
@Value("${ok.http.keep-alive-duration}")
private Long keepAliveDuration;
@Bean
public OkHttpClient okHttpClient() {
return new OkHttpClient.Builder()
.sslSocketFactory(sslSocketFactory(), x509TrustManager())
// 是否开启缓存

.connectionPool(pool())
.connectTimeout(connectTimeout, TimeUnit.SECONDS)

// 设置代理

4. OkHttp 类
import lombok.extern.slf4j.Slf4j;
import okhttp3.*;
import org.apache.commons.lang3.exception.ExceptionUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import java.util.Map;
/**

@Slf4j
@Component
public class OkHttpCli {
private static final MediaType JSON = MediaType.parse("application/json; charset=utf-8");
private static final MediaType XML = MediaType.parse("application/xml; charset=utf-8");
@Autowired
private OkHttpClient okHttpClient;
/**

* @param url 请求url地址
* @return string
* */
public String doGet(String url) {
return doGet(url, null, null);
}
/**
* get 请求
* @param url 请求url地址
* @param params 请求参数 map
* @return string
* */
public String doGet(String url, Map<String, String> params) {
return doGet(url, params, null);
}
/**
* get 请求
* @param url 请求url地址
* @param headers 请求头字段 {k1, v1 k2, v2, ...}
* @return string
* */
public String doGet(String url, String[] headers) {
return doGet(url, null, headers);
}
/**
* get 请求
* @param url 请求url地址
* @param params 请求参数 map
* @param headers 请求头字段 {k1, v1 k2, v2, ...}
* @return string
* */
public String doGet(String url, Map<String, String> params, String[] headers) {
StringBuilder sb = new StringBuilder(url);
if (params != null && params.keySet().size() > 0) {
boolean firstFlag = true;
for (String key : params.keySet()) {
if (firstFlag) {

}
}
}
Request.Builder builder = new Request.Builder();
if (headers != null && headers.length > 0) {
if (headers.length % 2 == 0) {
for (int i = 0; i < headers.length; i = i + 2) {
builder.addHeader(headers[i], headers[i + 1]);
}
} else {
log.warn("headers's length[{}] is error.", headers.length);
}
}
Request request = builder.url(sb.toString()).build();
log.info("do get request and url[{}]", sb.toString());
return execute(request);
}
/**
* post 请求
* @param url 请求url地址
* @param params 请求参数 map
* @return string
*/
public String doPost(String url, Map<String, String> params) {
FormBody.Builder builder = new FormBody.Builder();
if (params != null && params.keySet().size() > 0) {
for (String key : params.keySet()) {

}
}
Request request = new Request.Builder().url(url).post(builder.build()).build();
log.info("do post request and url[{}]", url);
return execute(request);
}
/**

* @return string
*/

}
} catch (Exception e) {
log.error(ExceptionUtils.getStackTrace(e));
} finally {
if (response != null) {

}
}
return "";
}
}
5. 使用验证
@RestController
public class AnswerController {
@Autowired
private OkHttpCli okHttpCli;
@RequestMapping(value = "show", method = RequestMethod.GET)
public String show() {
String url = "https://www.baidu.com/";
String message = okHttpCli.doGet(url);
return message;
}
}
6. 双向认证(待证)
@Bean
public SSLSocketFactory sslSocketFactory() {
String certPath = "";
String caPath = "";
String certPwd = "";
String caPwd = "";
try {
ClassPathResource selfcertPath = new ClassPathResource(certPath);
ClassPathResource trustcaPath = new ClassPathResource(caPath);
KeyStore selfCert = KeyStore.getInstance("pkcs12");
selfCert.load(selfcertPath.getInputStream(), certPwd.toCharArray());
KeyManagerFactory kmf = KeyManagerFactory.getInstance("sunx509");
kmf.init(selfCert, certPwd.toCharArray());
KeyStore caCert = KeyStore.getInstance("jks");
caCert.load(trustcaPath.getInputStream(), caPwd.toCharArray());
TrustManagerFactory tmf = TrustManagerFactory.getInstance("sunx509");
tmf.init(caCert);
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
return sslContext.getSocketFactory();
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
