(String)(jdbc拦截器——jdbc-pool的高级扩展属 性)用分号分隔的、继承org.apache.tomcat.jdbc.pool.JdbcInterceptor的类名列表。这些拦截器将被插入到对 java.sql.Connection操作之前的拦截器链上。 预制的拦截器有:
org.apache.tomcat.jdbc.pool.interceptor.ConnectionState - 追踪自动提交、只读状态、catalog和事务隔离等级等状态。(keeps track of auto commit, read only, catalog and transaction isolation level.)org.apache.tomcat.jdbc.pool.interceptor.StatementFinalizer - 追踪打开的statement,当连接被归还时关闭它们。(keeps track of opened statements, and closes them when the connection is returned to the pool.)更多预制拦截器详细描述请参见JDBC拦截器部分
