## 报错原因： ##

在springboot运行中，无法开启tomcat并报错，原因是org.ehcache和net.sf.ehcache有冲突，导入了两个版本的encache包。只需要排除其中一个包就可以正常运行了。经过查询原来是easyExcel里面带着有encache包，所以排除easyExcel里面的ehcache即可。

## 解决方案： ##

<dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>easyexcel</artifactId>
        <version>2.1.7</version>
        <exclusions>
            <exclusion>
                <artifactId>ehcache</artifactId>
                <groupId>org.ehcache</groupId>
            </exclusion>
        </exclusions>
    </dependency>
