oracle - Apache Tomcat/6.0.32 - Web 应用程序未启动

Question

我正在尝试在我的 tomcat 管理器上启动我的 webapp，但它没有启动。我正在读取 webapp 的日志文件，但出现此错误:

8-giu-2017 9.41.12 org.apache.catalina.core.StandardContext start GRAVE: Error listenerStart 8-giu-2017 9.41.12 org.apache.catalina.core.StandardContext start GRAVE: Context [/ImageProcessor] startup failed due to previous errors 8-giu-2017 9.41.12 org.apache.catalina.loader.WebappClassLoader clearReferencesJdbc GRAVE: The web application [/ImageProcessor] registered the JDBC driver [oracle.jdbc.OracleDriver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered. 8-giu-2017 9.41.12 org.apache.catalina.loader.WebappClassLoader clearReferencesThreads GRAVE: The web application [/ImageProcessor] appears to have started a thread named [oracle.jdbc.driver.BlockSource.ThreadedCachingBlockSource.BlockReleaser] but has failed to stop it. This is very likely to create a memory leak. 8-giu-2017 9.41.12 org.apache.catalina.loader.WebappClassLoader clearReferencesThreads GRAVE: The web application [/ImageProcessor] appears to have started a thread named [CommunicatorServer] but has failed to stop it. This is very likely to create a memory leak.

Answer 1

问题是“oracle.jdbc.driver.BlockSource.ThreadedCachingBlockSource.BlockReleaser”线程正在运行并且没有停止，因此 Tomcat 会将其显示为内存泄漏。您必须手动注销驱动程序。请参阅下面的链接以获取见解。
