PersistenceManager 无法连接到数据库

Question

当尝试运行使用 Jackrabbit（本地在 Tomcat7 上）的应用程序时，无论出于何种原因，它都无法连接到数据库。与 db 的连接从具有相同凭据的常规 Java 应用程序工作。如何调查连接性问题？有一个问题无法实例化持久性管理器 org.apache.jackrabbit.core.persistence.pool.MySqlPersistenceManager 但没有解释。数据库连接配置：<PersistenceManager class="org.apache.jackrabbit.core.persistence.pool.MySqlPersistenceManager">      <param name="driver" value="com.mysql.jdbc.Driver"/>      <param name="url" value="jdbc:mysql://localhost:3306/repo"/>      <param name="databaseType" value="mysql"/>      <param name="user" value="admin" />      <param name="password" value="password11.." />      <param name="schemaObjectPrefix" value="${wsp.name}_"/>      <param name="externalBLOBs" value="true"/></PersistenceManager>错误输出：[localhost-startStop-1] INFO org.apache.jackrabbit.core.RepositoryImpl - Starting repository...[localhost-startStop-1] INFO org.apache.jackrabbit.core.fs.local.LocalFileSystem - LocalFileSystem initialized at path jackrabbit\repository[localhost-startStop-1] INFO org.apache.jackrabbit.core.fs.local.LocalFileSystem - LocalFileSystem initialized at path jackrabbit\versionTue Aug 21 10:46:47 CEST 2018 WARN: Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

我已经解决了这个问题。Maven 附加到这个应用程序旧版本的 mysql 连接器，它应该是兼容的，但没有工作。
