新建一个spring boot 项目

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@RestController
public class DemoApplication {

    @GetMapping
    public String test() {
        return "hello";
    }

    @GetMapping("/test2")
    public String test2() {
        return "hello 2";
    }

    @GetMapping("/test3")
    public String test3() {
        return "hello 3";
    }

    @GetMapping("/test4")
    public String test4() {
        return "hello 4";
    }

    @GetMapping("/test5")
    public String test5() {
        return "hello 5";
    }

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

jenkins 新建 -> 构建一个maven项目
源码管理 -> Git -> Repository URL （填写自己项目）

构建触发器 -> Build whenever a SNAPSHOT dependency is built
每1分钟轮询
->Poll SCM (/1 * * * )

Post Steps -> Run only if build succeeds or is unstable
