Springcache 不僅適用於 XML 配置

Question

我正在用XML配置实现Springcache，并希望摆脱所有的注释。我只想替换应用程序Context.xml文件中的注释。这是我的代码 -//DummyBean.javapackage com.spring.example;interface DummyBean {    public String getCity();}//DummyBeanImpl.javapackage com.spring.example;import org.springframework.cache.annotation.CacheConfig;import org.springframework.cache.annotation.Cacheable;import org.springframework.cache.annotation.EnableCaching;@EnableCaching@CacheConfig(cacheNames={"myCache"})public class DummyBeanImpl implements DummyBean {    private String city = "New York";    @Cacheable()    public String getCity() {        System.out.println("DummyBean.getCity() called!");        return city;    }}SpringAwareAnnotationXMLConfig.javapackage com.spring.example;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.support.AbstractApplicationContext;import org.springframework.context.support.GenericXmlApplicationContext;public class SpringAwareAnnotationXMLConfig {  public static void main(String[] args) throws Exception {    AbstractApplicationContext context = new GenericXmlApplicationContext("applicationContext.xml");    DummyBean personService = (DummyBean) context.getBean("myBean");    System.out.println(personService.getCity());    System.out.println(personService.getCity());    System.out.println(personService.getCity());    ((AbstractApplicationContext) context).close();  }}

Answer 1

使用 XML 配置的各个方面时，您还需要添加一个部分来应用该方面。aop:config

<aop:config>
    <aop:advisor advice-ref="cacheAdvice" pointcut="execution(* com.spring.example.DummyBean+.*(..))"/>
</aop:config>

假设是一个由此实现的接口，应该可以解决问题。这表示您要将（方面）应用于与表达式匹配的 Bean。DummyBeancom.spring.example.DummyBeanImplcacheAdvice
