SpringBoot里使用Servlet进行请求

首先，在main方法的类上添加注解：

@ServletComponentScan(basePackages = "application.servlet")

示例代码:

package application;
    
    
    import io.seata.spring.annotation.datasource.EnableAutoDataSourceProxy;
    import javafx.application.Application;
    import javafx.fxml.FXMLLoader;
    import org.mybatis.spring.annotation.MapperScan;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.boot.builder.SpringApplicationBuilder;
    import org.springframework.boot.web.servlet.ServletComponentScan;
    import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
    import org.springframework.cache.annotation.EnableCaching;
    import org.springframework.cloud.openfeign.EnableFeignClients;
    
    import javax.annotation.Resource;
    
    /**
     * @author wtl
     */
    @SpringBootApplication
    @EnableFeignClients
    @EnableCaching
    @EnableAutoDataSourceProxy
    @MapperScan(basePackages = "application.mybatis.mappers")
    @ServletComponentScan(basePackages = "application.servlet")
    public class SpringBootMain extends SpringBootServletInitializer {
    
        public static void main(String[] args) {
            SpringApplication.run(SpringBootMain.class,args);
            Application.launch(FxmlRunner.class,args);
        }
    
        @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
            return builder.sources(SpringBootMain.class);
        }
    }

使用 @WebServlet(name = "DownloadServlet",urlPatterns = "/test") 进行使能Servlet：

@WebServlet(name = "DownloadServlet",urlPatterns = "/test")

示例：

package application.servlet;
    
    import application.service.BiliBiliIndexService;
    import lombok.SneakyThrows;
    
    import javax.annotation.Resource;
    import javax.servlet.*;
    import javax.servlet.annotation.WebServlet;
    import javax.servlet.http.HttpServlet;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import java.io.IOException;
    
    /**
     * @author: wtl
     * @Date: 2020/7/5
     * @Time: 18:48
     * @Description:
     */
    @WebServlet(name = "DownloadServlet",urlPatterns = "/test")
    public class DownloadServlet extends HttpServlet {
    
        @Resource
        private BiliBiliIndexService biliBiliIndexService;
    
        @SneakyThrows
        @Override
        protected void doGet(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws ServletException, IOException {
            String aid = httpServletRequest.getParameter("aid");
            String cid = httpServletRequest.getParameter("cid");
            biliBiliIndexService.getVideoStream(aid,cid,httpServletRequest,httpServletResponse);
        }
    }
