原因：这是版本的问题，参考一下下面的对照表

 修改一下对应的版本，正确的版本对应比如下面的：

<!--seata starter 采用1.4.2版本-->
        <dependency>
            <groupId>io.seata</groupId>
            <artifactId>seata-spring-boot-starter</artifactId>
            <version>${seata.version}</version>
        </dependency>
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-seata</artifactId>
            <version>2021.0.1.0</version>
            <exclusions>
                <exclusion>
                    <groupId>io.seata</groupId>
                    <artifactId>seata-spring-boot-starter</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
    </dependencies>

修改好，拉下依赖，重启就行了，我的是这么解决的(●ˇ∀ˇ●)
