1、首先是包的依赖
2、添加对外暴露的接口类
package com.fh.controller; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.ResponseBody; import org.springframework.web.bind.annotation.RestController; @RestController public class IndexController { public IndexController(){ System.out.println("indexController初始化"); } @GetMapping("index") @ResponseBody public String index(){ return "index"; } }
3、添加配置类信息
package com.fh.config; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; @Configuration @ComponentScan("com.fh") public class AutoConfig { }
4、添加主类进行SpringWeb环境的初始化和Tomcat的启动
package com.fh;
import com.fh.config.AutoConfig;
import org.apache.catalina.Context;
import org.apache.catalina.Server;
import org.apache.catalina.connector.Connector;
import org.apache.catalina.startup.Tomcat;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.servlet.DispatcherServlet;
import java.io.File;
public class ExampleMvcApplication {
public static void main(String[] args) throws Exception {
AnnotationConfigWebApplicationContext context =
new AnnotationConfigWebApplicationContext();
context.register(AutoConfig.class);
context.refresh();
File base = new File(System.getProperty("java.io.tmpdir"));
Tomcat tomcat = new Tomcat();
/**
* web项目
* contextPath tomcat的访问路径
* 项目的web目录
*
* 会调用相关的初始化实现类
*/
// Context context1 = tomcat.addWebapp("/", base.getAbsolutePath());
DispatcherServlet dispatcherServlet = new DispatcherServlet(context);
Context context1 = tomcat.addContext("/", base.getAbsolutePath());
//tomcat启动的过程中会调用DispatcherServlet中的init方法
Tomcat.addServlet(context1,"my",dispatcherServlet).setLoadOnStartup(1);
//spring web环境
context1.addServletMappingDecoded("/","my");
// context1.addServletMapping("/","my");
//tomcat8
// tomcat.setPort(8080);
// tomcat.start();
// tomcat.getServer().await();
//tomcat9
Server server = tomcat.getServer();
Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
connector.setPort(8080);
connector.setThrowOnFailure(true);
tomcat.getService().addConnector(connector);
tomcat.setConnector(connector);
tomcat.start();
server.await();
}
}
