可以看到，在第一次报错信息中有提示 JDK9+不支持clientBuilder.sslSocketFactory(SSLSocketFactory)，我们项目环境统一使用JDK8，但是具体版本却不一样，我排查问题时没有考虑到这一点，而这恰恰是报错的原因。谨记！谨记！
解决方法修改封装工具类中静态方法getUnsafeOkHttpClient。
原代码：
public static OkHttpClient getUnsafeOkHttpClient() {
try {
final TrustManager[] trustAllCerts = new TrustManager[]{
new X509TrustManager() {
@Override
public void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType) {
}
@Override
public void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType) {
}
@Override
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return new java.security.cert.X509Certificate[]{};
}
}
};
final SSLContext sslContext = SSLContext.getInstance("SSL");
sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
final javax.net.ssl.SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();
OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.sslSocketFactory(sslSocketFactory);
builder.hostnameVerifier(new HostnameVerifier() {
@Override
public boolean verify(String hostname, SSLSession session) {
return true;
}
});
return builder.build();
} catch (Exception e) {
throw new RuntimeException(e);
}
}
修改后代码：
public static OkHttpClient getUnsafeOkHttpClient() {
try {
final TrustManager[] trustAllCerts = new TrustManager[]{
new X509TrustManager() {
@Override
public void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType) {
}
@Override
public void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType) {
}
@Override
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return new java.security.cert.X509Certificate[]{};
}
}
};
final SSLContext sslContext = SSLContext.getInstance("SSL");
X509TrustManager trustManager = (X509TrustManager)trustAllCerts[0];
sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
final javax.net.ssl.SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();
OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.sslSocketFactory(sslSocketFactory,trustManager);
builder.hostnameVerifier(new HostnameVerifier() {
@Override
public boolean verify(String hostname, SSLSession session) {
return true;
}
});
return builder.build();
} catch (Exception e) {
throw new RuntimeException(e);
}
}
