今天开始学习 Spring Boot, 后面的文章会结合两者区别一边学习一边理解用法上的区别

Java 环境配置就不说明了

Java:

创建一个类 命名为 HomeController

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HomeController {
@RequestMapping(
"/helloworld")

</span><span style="color: rgba(0, 0, 255, 1)">public</span><span style="color: rgba(0, 0, 0, 1)"> String Index()
{
   </span><span style="color: rgba(0, 0, 255, 1)">return</span>  "Hello World"<span style="color: rgba(0, 0, 0, 1)">;
}

}

.NetCore

using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;

namespace ExpressServices.Controllers
{
public class HomeController : Controller
{
[Route(
"~/helloworld")]
public IActionResult Index()
{
return Content("Hello World");
}
}
}

路由区别

路由:@RequestMapping("/helloworld")  vs   [Route("~/helloworld")]

包引用区别

import org.springframework.web.bind.annotation.RestController
using Microsoft.AspNetCore.Mvc;

主程序入口

@SpringBootApplication
public class DemoApplication {
</span><span style="color: rgba(0, 0, 255, 1)">public</span> <span style="color: rgba(0, 0, 255, 1)">static</span> <span style="color: rgba(0, 0, 255, 1)">void</span><span style="color: rgba(0, 0, 0, 1)"> main(String[] args) {
    SpringApplication.run(DemoApplication.</span><span style="color: rgba(0, 0, 255, 1)">class</span><span style="color: rgba(0, 0, 0, 1)">, args);
}

}

public class Program
    {
        public static void Main(string[] args)
        {CreateWebHostBuilder(args).Build().Run();
        }
    </span><span style="color: rgba(0, 0, 255, 1)">public</span> <span style="color: rgba(0, 0, 255, 1)">static</span> IWebHostBuilder CreateWebHostBuilder(<span style="color: rgba(0, 0, 255, 1)">string</span>[] args) =&gt;<span style="color: rgba(0, 0, 0, 1)">
        WebHost.CreateDefaultBuilder(args)
           .UseUrls(</span><span style="color: rgba(128, 0, 0, 1)">"</span><span style="color: rgba(128, 0, 0, 1)">http://localhost:20002</span><span style="color: rgba(128, 0, 0, 1)">"</span><span style="color: rgba(0, 0, 0, 1)">)
            .UseStartup</span>&lt;Startup&gt;<span style="color: rgba(0, 0, 0, 1)">();
}</span></pre>

都有很多相似之处,思想上没什么区别,所以 一个 Hello World 很快就搞定了 ~

运行下 Spring Boot 项目
