canal 数据行解析错误

maven使用canal构建的项目，包数据行解析错误：如下

一开始考虑是jar包不完整错误，后来发现是因为canal引用的guava一个被废弃的方法导致的:

具体如下：

   canal版本1.20

   maven中自动依赖的guava版本19.0

解决方案：

  将maven自动依赖的guava版本降为18.0 。在pom中选择性的加入如下代码，其中 xxxx 部分为 依赖guava 的jar包。pom中寻找依赖guava的jar包，可以在 pom.xml中右击选择maven->show dependencies  找到guava即可。

<dependency>    <groupId>xxxxx</groupId>    <artifactId>xxxxx</artifactId>    <version>xxxxxT</version>    <exclusions>        <exclusion>            <artifactId>guava</artifactId>            <groupId>com.google.guava</groupId>        </exclusion>    </exclusions></dependency><dependency>    <groupId>com.google.guava</groupId>    <artifactId>guava</artifactId>    <version>18.0</version></dependency>
