OkHttp3 4.11.0 信任所有证书编译报错解决：cannot find symbol

针对你在Oracle 19c环境下编译嵌入Java代码时，调用builder1.sslSocketFactory(trustAllSslSocketFactory, (X509TrustManager) trustAllCerts[0])出现的“cannot find symbol”错误，可按以下步骤排查解决：

确认依赖完整性
确保Oracle 19c的Java环境中已加载OkHttp 4.11.0及其依赖（如Okio）的jar包。若为嵌入式Java代码（如JDBC存储过程），需用loadjava命令将相关jar包导入Oracle的类路径，避免因缺失依赖导致方法无法识别。
修正方法调用的类型匹配
OkHttp 4.x的sslSocketFactory方法要求两个参数：SSLSocketFactory实例和X509TrustManager实例。需确保：
1. 显式导入所有相关类：javax.net.ssl.SSLSocketFactory、javax.net.ssl.X509TrustManager、javax.net.ssl.SSLContext等，避免编译时类型缺失。
2. 将类型转换结果赋值给变量后再传入，帮助编译器识别类型：
```
X509TrustManager trustManager = (X509TrustManager) trustAllCerts[0];
builder1.sslSocketFactory(trustAllSslSocketFactory, trustManager);
```

检查自定义SSLSocketFactory的正确性
确认你的trustAllSslSocketFactory实例创建过程无错误，标准实现示例：

TrustManager[] trustAllCerts = new TrustManager[]{
    new X509TrustManager() {
        @Override
        public void checkClientTrusted(X509Certificate[] chain, String authType) {}
        @Override
        public void checkServerTrusted(X509Certificate[] chain, String authType) {}
        @Override
        public X509Certificate[] getAcceptedIssuers() { return new X509Certificate[0]; }
    }
};

SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(null, trustAllCerts, new SecureRandom());
SSLSocketFactory trustAllSslSocketFactory = sslContext.getSocketFactory();
