오류나는 클래스를 살펴보니 모두 TEST 케이스에서만 에러난다.

패키지를 못 읽어 오는 것이기에 pom.xml 을 수정해야 한다.

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

에서 scope 를 삭제한다. 아래처럼  

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