最佳答案
由于您是通过HTTPS访问API，因此您的客户端必须拥有自己的信任库。为此，您可以将EMM的密钥库用作您的信任库。否则，您可以创建自己的信任库。
System.setProperty("javax.net.ssl.trustStore", "$EMM_HOME/repository/resources/security/wso2carbon.jks");
System.setProperty("javax.net.ssl.trustStorePassword", "wso2carbon");
System.setProperty("javax.net.ssl.trustStoreType", "JKS");
