Spring Boot 简单使用EhCache缓存框架的方法

compile("org.springframework.boot:spring-boot-starter-cache")
compile("net.sf.ehcache:ehcache")

@MapperScan("com.xxx.xxx.dao")
@SpringBootApplication(scanBasePackages= arrayOf("com.xxx.xxx"))
// 启用缓存注解
@EnableCaching
// 启动定时器
@EnableScheduling
open class MyApplication {}

fun main(args: Array<String>) {
  SpringApplication.run(MyApplication::class.java, *args)
}

class User : Serializable {

}
// 获取缓存实例
val userCache = CacheManager.getInstance().getCache("userCache")
// 写入缓存
val element = Element("1000", User(1000,"Wiki"))
userCache.put(element)
// 读取缓存
val user = userCache.get("1000").objectValue as User
