为bean指定InitMethod和DestroyMethod spring注解怎样为bean指定InitMethod和DestroyMethod

/**
 *  指定组建的init方法和destroy的几种方法
 *      1：在配置类中 @Bean(initMethod = "init",destroyMethod = "destory")注解指定
 *      2：实现InitializingBean接口重写其afterPropertiesSet方法，实现DisposableBean接口重写destroy方法
 *      3：利用java的JSR250规范中的@PostConstruct标注在init方法上，@PreDestroy标注在destroy注解上
