Try adding the spring-expression dependency:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-expression</artifactId>
    <version>whatever ver. is comatible with your ver. of spring boot</version>
</dependency>

or alternatively

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

which may bring in the missing dependency.
