2.35 使用

1. 创建项目

2. pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    </parent>

    <dependencies>
        <!-- aop -->

        </dependency>
    </dependencies>
</project>

3. 代码

• Application.java

@EnableCaching//默认已经开启
@SpringBootApplication()
public class Application
{
    public static void main(String[] args)
    {
        SpringApplication.run(Application.class, args);
        System.out.println("==================================服务已启动==================================");

    }
}

• TestApplication.java

@SpringBootTest(classes = Application.class)
@RunWith(SpringRunner.class)
public class TestApp
{
    @Autowired
    private TestController testController;

    @Test
    public void test()
    {
        testController.test();//第一次会进入TestService的逻辑
        testController.test();//第二次直接由代理类返回缓存
    }
}

• TestController

@Service
public class TestController
{
    @Autowired//注入的这个其实是个代理类
    private TestService testService;

    public void test()
    {
        String byId = testService.getById(1);
        System.out.println(byId);
    }
}

• TestService

@Service
public class TestService
{
    @Cacheable("test")
    public String getById(Integer id)
    {
        return "" + id;
    }
}
