报错信息:
java.lang.Object.wait(Native Method)
java.lang.ref.ReferenceQueue.remove(ReferenceQueue.java:143)
com.mysql.jdbc.AbandonedConnectionCleanupThread.run(AbandonedConnectionCleanupThread.java:43)
每次出现这个报错都会导致tomcat应用服务器停机，加了下面的java代码后就再也没有停过了。
解决办法:
编写Java代码
package cn.listener; import java.sql.Driver; import java.sql.DriverManager; import java.sql.SQLException; import java.util.Enumeration; import javax.servlet.ServletContextEvent; import javax.servlet.ServletContextListener; import javax.servlet.annotation.WebListener; import com.mysql.jdbc.AbandonedConnectionCleanupThread; @WebListener public class ContextFinalizer implements ServletContextListener { public void contextInitialized(ServletContextEvent sce) { } public void contextDestroyed(ServletContextEvent sce) { Enumeration<Driver> drivers = DriverManager.getDrivers(); Driver d = null; while (drivers.hasMoreElements()) { try { d = drivers.nextElement(); DriverManager.deregisterDriver(d); System.out.println(String.format("ContextFinalizer:Driver %s deregistered", d)); } catch (SQLException ex) { System.out.println(String.format("ContextFinalizer:Error deregistering driver %s", d) + ":" + ex); } } try { AbandonedConnectionCleanupThread.shutdown(); } catch (InterruptedException e) { System.out.println("ContextFinalizer:SEVERE problem cleaning up: " + e.getMessage()); e.printStackTrace(); } } }
@WebListener，这个注解相当于在web.xml配置如下内容
<listener> <listener-class>cn.listener.ContextFinalizer</listener-class> </listener>
解决方案可以参考如下网址:https://stackoverflow.com/questions/25699985/the-web-application-appears-to-have-started-a-thread-named-abandoned-connect
当然还有就是我再参考这个解决方案的时候，发现mysql-connection如果版本过低会导致上述列出的Java代码报错，通过提高mysql-connection.java的版本即可解决该问题
