TrustManagerUtil是Hutool中用于处理SSL(Secure Sockets Layer 安全套接字协议)中TrustManager的工具类，提供了多种获取和创建TrustManager的方法，用于管理可信任的证书等信息。

主要功能

• 获取默认的X509TrustManager
• 从KeyStore获取X509TrustManager
• 获取默认的TrustManager数组
• 从KeyStore获取TrustManager数组
• 获取TrustManagerFactory
• 提供信任所有证书的TrustManager常量

常量说明

• TRUST_ANYS：信任所有证书的X509TrustManager数组，包含TrustAnyTrustManager实例

主要方法

getDefaultTrustManager()

获取默认的X509TrustManager，主要用于获取自签证书的X509TrustManager。

getTrustManager(KeyStore keyStore, Provider provider)

从指定的KeyStore获取X509TrustManager，可指定算法提供者。

getTrustManager(KeyStore keyStore, String algorithm, Provider provider)

从指定的KeyStore获取X509TrustManager，可指定算法名称和提供者。

getDefaultTrustManagers()

获取默认的TrustManager数组。

getTrustManagers(KeyStore keyStore)

从指定的KeyStore获取TrustManager数组。

getTrustManagers(KeyStore keyStore, String algorithm, Provider provider)

从指定的KeyStore获取TrustManager数组，可指定算法名称和提供者。

getTrustManagerFactory(KeyStore keyStore, String algorithm, Provider provider)

获取指定的TrustManagerFactory，可指定算法名称和提供者。

示例代码

获取默认的X509TrustManager

X509TrustManager trustManager = TrustManagerUtil.getDefaultTrustManager();

使用信任所有证书的TrustManager

// 获取信任所有证书的TrustManager数组
X509TrustManager[] trustManagers = TrustManagerUtil.TRUST_ANYS;

// 用于创建SSLContext
SSLContext sslContext = SSLContextUtil.createSSLContext("TLS", null, trustManagers);

从KeyStore获取TrustManager

// 加载KeyStore
KeyStore keyStore = KeyStore.getInstance("JKS");
try (InputStream is = new FileInputStream("path/to/truststore.jks")) {
    keyStore.load(is, "password".toCharArray());
}

// 获取X509TrustManager
X509TrustManager trustManager = TrustManagerUtil.getTrustManager(keyStore, null);

// 获取TrustManager数组
TrustManager[] trustManagers = TrustManagerUtil.getTrustManagers(keyStore);

指定算法获取TrustManager

// 使用PKIX算法获取TrustManager
X509TrustManager trustManager = TrustManagerUtil.getTrustManager(keyStore, "PKIX", null);

获取TrustManagerFactory

// 获取TrustManagerFactory
TrustManagerFactory trustManagerFactory = TrustManagerUtil.getTrustManagerFactory(keyStore, "SunX509", null);

// 从TrustManagerFactory获取TrustManager数组
TrustManager[] trustManagers = trustManagerFactory.getTrustManagers();
