LightWebServer是一个轻量级的嵌入式web服务器,同时提供了简单的mvc框架。
- Java version >= 1.8
- mvn -Dmaven.test.skip=true clean install
- include maven dependency

<dependency>

LightWebServer is similar to Spring MVC.
@Controller --> 类似Spring MVC中的@Controller
@WebPath --> 类似Spring MVC中的@RequestMapping
- @QueryParam 得到GET参数
- @FormParam 得到x-www-form-urlencoded类型POST方法的参数
- @MultiPartData 得到multipart/form-data类型POST方法得到的参数
- HttpServletRequest无需注解即可注入
- 目前只能返回com.light.http.responses.Response
- Create controller
import com.light.http.HttpMethod;
import com.light.http.HttpStatus;
import com.light.http.requests.MimeData;
import com.light.http.responses.FileResponse;
import com.light.http.responses.JsonResponse;
import com.light.http.responses.Response;
import com.light.mvc.annotations.*;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.HashMap;
import java.util.Map;
@Controller
public class HelloWorldController {
// GET
@WebPath("/testGet")
public Response testGet(@QueryParam(value = "name",required = true)String name,Request request){
Map<String,String> map = new HashMap<>();
map.put("hello",name);
return new JsonResponse(HttpStatus.OK_200,map);
}
// POST 请求的Content-Type为multipart/form-data
@WebPath(value = "/testPost1",method = HttpMethod.POST)
public Response testPost1(@MultiPartData("photo")MimeData photo,
@MultiPartData("name")MimeData name,
@MultiPartData("age")MimeData age){
System.out.println("hello " + new String(name.getData()) + ", your age is " + new String(age.getData()));
byte[] data = photo.getData();
try {
File file = File.createTempFile("the",".jpeg");
FileOutputStream os = new FileOutputStream(file);
os.write(data);
os.close();
return new FileResponse(HttpStatus.OK_200,file);
} catch (IOException e) {
e.printStackTrace();
}
return new Response(HttpStatus.OK_200);
}
// POST 请求的Content-Type为application/x-www-form-urlencoded
@WebPath(value = "/testPost2", method = HttpMethod.POST)
public Response testPost2(@FormParam("name")String name, @QueryParam("age")Integer age){
System.out.println("hello " + name + ", your age is " + age);
return new Response(HttpStatus.OK_200);
}
}
- Start Server
import com.light.io.Server; import java.io.IOException; public class Application { public static void main(String[] args) throws IOException { Server server = new Server(); //第二个参数指定扫描@Controller的包名,可以是多个 server.run(new String[]{"start","localhost:8080"}, new String[]{"your_controller_pkg_path1","your_controller_pkg_path2"}); } }
