目前现状，jedis版本是2.4.2，没有引入common包

报错：

The eventual following stack trace is caused by an error thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access, and has no functional impact.

查了半天，说是jar包冲突

解决办法：

将jedisjar包改成2.9.0

加入如下代码：

<dependency>
			<groupId>redis.clients</groupId>
			<artifactId>jedis</artifactId>
			<version>${jedis.version}</version>
			<exclusions>
				<exclusion>
					<artifactId>commons-pool2</artifactId>
					<groupId>org.apache.commons</groupId>
				</exclusion>
			</exclusions>
		</dependency>

                 <dependency>
			<groupId>org.apache.commons</groupId>
			<artifactId>commons-pool2</artifactId>
			<version>2.4.2</version>
		</dependency>

分析原因：

jedis包中引用了common pool2的jar包
