详解springboot容器加载完后执⾏特定操作
有时候我们需要在spring boot容器启动并加载完后，开⼀些线程或者⼀些程序来⼲某些事情。这时候我们需要配置ContextRefreshedEvent事件来实现我们要做的事情
1、ApplicationStartup类
public class ApplicationStartup implements ApplicationListener<ContextRefreshedEvent>{
一封辞职信
public void onApplicationEvent(ContextRefreshedEvent event)
{
//在容器加载完毕后获取dao层来操作数据库高中教科书
OSSVideoRepository ossVideoRepository = (ApplicationContext().getBean(OSSVideoRepository.class); //在容器加载完毕后获取配置⽂件中的配置
ServerConfig rverConfig = (ApplicationContext().getBean(ServerConfig.class);
ServerFileScanner fileScanner = new ServerFileScanner(
ossVideoRepository, Scanpath());
//在容器加载完毕后启动线程
Thread thread = new Thread(fileScanner);
thread.start();
}
}
2、ServerConfig 类
@Component
@ConfigurationProperties(prefix = "rver")
public class ServerConfig {
鸡翅根怎么做private String aliyunossEndpoint;
private String aliyunossAccessKeyId;
private String aliyunossAccessKeySecret;
private String aliyunossBucketName;
private String scanpath;
public String getAliyunossEndpoint() {
return aliyunossEndpoint;
}
public void tAliyunossEndpoint(String aliyunossEndpoint) {
this.aliyunossEndpoint = aliyunossEndpoint;
}
public String getAliyunossAccessKeyId() {
return aliyunossAccessKeyId;
}
public void tAliyunossAccessKeyId(String aliyunossAccessKeyId) {
this.aliyunossAccessKeyId = aliyunossAccessKeyId;
有关清明的诗句}
public String getAliyunossAccessKeySecret() {
return aliyunossAccessKeySecret;
}
public void tAliyunossAccessKeySecret(String aliyunossAccessKeySecret) {
this.aliyunossAccessKeySecret = aliyunossAccessKeySecret;
}
public String getAliyunossBucketName() {
有必要的英语return aliyunossBucketName;
}
参加比赛
public void tAliyunossBucketName(String aliyunossBucketName) {
this.aliyunossBucketName = aliyunossBucketName;
软终端}
public String getScanpath() {
return scanpath;
}
public void tScanpath(String scanpath) {
this.scanpath = scanpath;
}
28car}
PS：还有⼀些spring内置的事件
1、 ContextRefreshedEvent：ApplicationContext容器初始化或者刷新时触发该事件。
2、 ContextStartedEvent：当使⽤ConfigurableApplicationContext接⼝的start()⽅法启动ApplicationContext容器时触发该事件。
3、 ContextClodEvent：当使⽤ConfigurableApplicationContext接⼝的clo()⽅法关闭ApplicationContext容器时触发该事件。
4、 ContextStopedEvent: 当使⽤ConfigurableApplicationContext接⼝的stop()⽅法停⽌ApplicationContext容器时触发该事件。
