druid-spring-boot-starter整合hive与hadoop的排除类

hive-jdbc和jetty冲突，所以在hive-jdbc中对jetty进行排除就OK

<exclusions>
	<exclusion>
		<groupId>org.eclipse.jetty.aggregate</groupId>
		<artifactId>*</artifactId>
	</exclusion>
</exclusions>

servlet冲突

***************************
APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    org.apache.catalina.authenticator.AuthenticatorBase.startInternal(AuthenticatorBase.java:1178)

The following method did not exist:

    javax.servlet.ServletContext.getVirtualServerName()Ljava/lang/String;

The method's class, javax.servlet.ServletContext, is available from the following locations:

    jar:file:/D:/apache-maven-3.6.1/repository/javax/servlet/servlet-api/2.5/servlet-api-2.5.jar!/javax/servlet/ServletContext.class
    jar:file:/D:/apache-maven-3.6.1/repository/javax/servlet/javax.servlet-api/4.0.1/javax.servlet-api-4.0.1.jar!/javax/servlet/ServletContext.class
    jar:file:/D:/apache-maven-3.6.1/repository/org/apache/tomcat/embed/tomcat-embed-core/9.0.21/tomcat-embed-core-9.0.21.jar!/javax/servlet/ServletContext.class

It was loaded from the following location:

    file:/D:/apache-maven-3.6.1/repository/javax/servlet/servlet-api/2.5/servlet-api-2.5.jar


Action:

Correct the classpath of your application so that it contains a single, compatible version of javax.servlet.ServletContext
 
Task(cat-TcpSocketSender) is shutdown! 
Task(cat-TcpSocketSender-ChannelManager) is shutdown! 
Task(cat-StatusUpdateTask) is shutdown! 
[0x7FFEDAFCE0A4] ANOMALY: use of REX.w is meaningless (default operand size is 64)

Process finished with exit code 1 

解决方法：
在自己添加的pom文件后面添加排除：

<exclusion>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
</exclusion>
