If you're configuring your application with XML, you can enable annotation-driven caching with the <cache:annotation-driven> element from Spring's cache namespace, as follows:

    <?xml version="1.0" encoding="UTF-8"?> 
    <beans xmlns="http://www.springframework.org/schema/beans" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xmlns:context="http://www.springframework.org/schema/context" 
     xmlns:jdbc="http://www.springframework.org/schema/jdbc" 
     xmlns:tx="http://www.springframework.org/schema/tx" 
     xmlns:aop="http://www.springframework.org/schema/aop" 
     xmlns:cache="http://www.springframework.org/schema/cache" 
     xsi:schemaLocation="http://www.springframework.org/schema/jdbc 
     http://www.springframework.org/schema/jdbc/spring-jdbc-4.3.xsd 
     http://www.springframework.org/schema/cache   
     http://www.springframework.org/schema/cache/spring-cache-4.3.xsd 
     http://www.springframework.org/schema/beans     
     http://www.springframework.org/schema/beans/spring-beans.xsd 
     http://www.springframework.org/schema/context    
     http://www.springframework.org/schema/context/spring-context.xsd 
     http://www.springframework.org/schema/aop 
     http://www.springframework.org/schema/aop/spring-aop-4.3.xsd 
     http://www.springframework.org/schema/tx 
     http://www.springframework.org/schema/tx/spring-tx-4.3.xsd"> 
     
     <!-- Enable caching --> 
     <cache:annotation-driven /> 
     
     <context:component-scan base-   
     package="com.packt.patterninspring.chapter9.bankapp"/> 
      
     <!-- Declare a cache manager --> 
     <bean id="cacheManager" 
     class="org.springframework.cache.concurrent.
     ConcurrentMapCacheManager" /> 
   </beans> 
 

As seen in the preceding configuration files, whether you use Java configuration or XML configuration, the annotation @EnableCaching and namespace <cache:annotation-driven> enables Spring's cache abstraction by creating an aspect with pointcuts that trigger off of Spring's caching annotations.

Let's see how to use Spring's caching annotations to define cache boundaries.
