首先，pom文件要有一下依赖：

<!-- SpringBootText注解依赖 -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
</dependency>

<!-- Junit依赖 -->
<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <scope>test</scope>
</dependency>

其次，测试类添加如下注解：

缺少jar依赖？

1 查看配置文件是否有误
2 查看数据库是否正常连接
3 换下其他版本jdk
4 在pom.xml文件中加入以下依赖

<dependency>
            <groupId>javax.xml.bind</groupId>
            <artifactId>jaxb-api</artifactId>
            <version>2.3.0</version>
        </dependency>
        <dependency>
            <groupId>com.sun.xml.bind</groupId>
            <artifactId>jaxb-impl</artifactId>
            <version>2.3.0</version>
        </dependency>
        <dependency>
            <groupId>com.sun.xml.bind</groupId>
            <artifactId>jaxb-core</artifactId>
            <version>2.3.0</version>
        </dependency>
        <dependency>
            <groupId>javax.activation</groupId>
            <artifactId>activation</artifactId>
            <version>1.1.1</version>
        </dependency>

需要以下依赖:

       <dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-web</artifactId>
      </dependency>

pandora容器在运行单元测试时也需要这个依赖。
如果还有任何问题，可以随时沟通交流。
请采纳，十分感谢！

根本原因是WEB-INF未包含在类路径中,引用类路径加斜杠很重要。以后发错误代码上来。
@ContextConfiguration("/applicationContext.xml")

@ContextConfiguration(locations={"classpath:WEB-INF/application-context.xml"})
