## 异常原因 ##

test的包是idea自动导入的，版本不一致。

--------------------

## 解决方案 ##

更改test的版本和项目的spring的一致

<dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-test</artifactId>
                <version>${spring.version}</version>
                <scope>compile</scope>
            </dependency>
