当前springboot  为按顺序执行3个不同的类

1.开始执行

package com.soft.startup;
    
    import org.springframework.boot.CommandLineRunner;
    import org.springframework.core.annotation.Order;
    import org.springframework.stereotype.Component;
    
    /**
     * @ClassName AfterServiceStarted
     * @Description 项目启动过程中执行一次 顺序为5
     * @Author issuser
     * @Date 2019/9/11 8:29
     * @Version 1.0.0
     */
    @Order(5)
    @Component
    public class AfterServiceStarted implements CommandLineRunner {
        @Override
        public void run(String... args) throws Exception {
        }
    }

2. 然后执行

package com.soft.startup;
    import org.springframework.boot.ApplicationArguments;
    import org.springframework.boot.ApplicationRunner;
    import org.springframework.core.annotation.Order;
    import org.springframework.stereotype.Component;
    import java.util.Properties;
    import static io.github.biezhi.ome.OhMyEmail.SMTP_QQ;
    
    /**
     * @ClassName AfterEmailService
     * @Description 项目启动过程中执行一次 启动顺序为6
     * @Author issuser
     * @Date 2019/9/11 8:30
     * @Version 1.0.0
     */
    @Order(6)
    @Component
    public class AfterEmailService implements ApplicationRunner {
        @Override
        public void run(ApplicationArguments args) throws Exception {
           
            System.out.println("AfterEmailService ...");
        }
    }

3.最后执行

package com.soft.startup;
    
    import io.github.biezhi.ome.OhMyEmail;
    import org.springframework.boot.ApplicationArguments;
    import org.springframework.boot.ApplicationRunner;
    import org.springframework.core.annotation.Order;
    import org.springframework.stereotype.Component;
    
    import static io.github.biezhi.ome.OhMyEmail.SMTP_QQ;
    
    /**
     * @ClassName AfterEmailService
     * @Description 项目启动过程中执行一次 启动顺序为7
     * @Author issuser
     * @Date 2019/9/11 8:30
     * @Version 1.0.0
     */
    @Order(7)
    @Component
    public class AfterOtherService implements ApplicationRunner {
        @Override
        public void run(ApplicationArguments args) throws Exception {
        }
    }
