Spring boot 知識點

1 資料預載入

實現CommandLineRunner介面

@Component
@Order(value = 2)
public class DataLoadRunner2 implements CommandLineRunner{
	@Override
	public void run(String... strings) throws Exception {
	    System.out.println("------資料載入 order 2 ------");
	}
}

@Component
@Order(value = 1)
 

public class DataLoadRunner1 implements CommandLineRunner {
	@Override
	public void run(String... strings) throws Exception {
    	System.out.println("------資料載入 order 1 ------");
    }
}

2 設定前端session 超時時間（預設30min）

@SpringBootApplication(scanBasePackages = {"com"})
@EnableDubboConfiguration
@MapperScan
 
({"bdass", "admin", "com.coinquant"})
@EnableCaching
public class QuantAdminApp {
    @Value("${server.sessionTimeout:36000}")
    private int sessionTimeout;
    public static Logger logger = LoggerFactory.getLogger(QuantAdminApp.class);
    public static void main(String args[]) {
       
        SpringApplication.
 
run(QuantAdminApp.class, args);
        new TimerTaskThrd().getAccountRegular();
    }

    @Bean
    public EmbeddedServletContainerCustomizer containerCustomizer() {
        return new EmbeddedServletContainerCustomizer() {
            @Override
            public void customize(ConfigurableEmbeddedServletContainer container) {
                container.setSessionTimeout(sessionTimeout);//單位為S
            }
        };
    }
}
