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
