Spring Cloud Task helloworld

引入maven
<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-task</artifactId>
            <version>1.2.3.RELEASE</version>
        </dependency>

Application 啓動類上加上@EnableTask註解

package xyz.zinglizingli;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.task.configuration.EnableTask;
import org.springframework.scheduling.annotation.EnableScheduling;

@EnableTask
@SpringBootApplication
@EnableScheduling
@MapperScan({"xyz.zinglizingli.*.mapper"})
public class CrawlApplication {

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

建立task類方式
實現CommandLineRunner 接口
經過註解的方式注入bean
@Component
public class HelloWorldCommandLineRunner implements CommandLineRunner {

    @Override
    public void run(String... args) throws Exception {
        // TODO Auto-generated method stub
        System.out.println("this is a task1");
    }

}
經過@bean註解注入
@Bean
public CommandLineRunner commandLineRunner() {
    return new HelloWorldCommandLineRunner();
}
