spring-boot JSR107缓存实战

这几天在开发的项目中，考虑引入一些缓存机制。顺便又了解了一下spring-boot的缓存、以及JSR107、ehcache。并做了一些使用实例。

spring-boot缓存使用实例

spring-boot中引入依赖spring-boot-starter-cache，pom.xml:

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

/**
 * 启动类
 */
@SpringBootApplication
@EnableAutoConfiguration
@EnableCaching // 启用缓存
public class Application extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }
}

/**
 * restful类
 */
@RestController
public class SampleController {
    @Autowired
    private SampleServiceImpl sampleService;

    @RequestMapping("/sample/test")
    public BaseQueryParam test(BaseQueryParam dto) {
        return sampleService.testCache(dto);
    }

}

@Service
public class SampleServiceImpl {

    // 取第一个参数可以用这几种姿势#root.args[1]或#p0或#a0
    @Cacheable(value="SampleServiceImpl", key="#p0.resourceId")
    public BaseQueryParam testCache(BaseQueryParam param) {
        System.out.println("第1次访问时未缓存，打印此文本");
        return param;
    }

}

public class BaseQueryParam {
    /**
     * 资源标识。主要用来标识需要访问的资源类型
     */
    private String resourceId;

    public String getResourceId() {
        return resourceId;
    }

    public void setResourceId(String resourceId) {
        this.resourceId = resourceId;
    }

}
