You can use hystrix-javanica library which offers hystrix command annotation very similar to what spring-boot offers. However, still you should add AOP to your project to interpret the annotation. The maven library is:
<dependency>
<groupId>com.netflix.hystrix</groupId>
<artifactId>hystrix-javanica</artifactId>
<version>1.5.18</version>
</dependency>
and this is a link to their GitHub project:
