内嵌Tomcat和SpringMVC的简单整合测试

内嵌Tomcat和SpringMVC的简单整合测试

添加对外暴露的接口类

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class TestController {
    @RequestMapping("test")
    public String test(){
        System.out.println("111111");
        return "index";
    }
}

添加配置类信息

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

@Configuration
@ComponentScan("com.github.alenfive.rocketapi.app")
@EnableWebMvc
public class WebMvcConfig {
}

添加配置类信息

import com.github.alenfive.rocketapi.app.WebMvcConfig;
import org.apache.catalina.Context;
import org.apache.catalina.LifecycleException;
import org.apache.catalina.Wrapper;
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.IOException;

//添加主类进行SpringWeb环境的初始化和Tomcat的启动
public class ExampleMvcApplication{

  public static void main(String[] args) throws LifecycleException, IOException {
      Tomcat tomcat = new Tomcat();
      tomcat.setPort(80);
      Context context = tomcat.addContext("/","d:/embedTomcat/");
      Connector conn = tomcat.getConnector(); // Tomcat 9.0 必须调用 Tomcat#getConnector() 方法之后才会监听端口
      System.out.println("连接器设置完成: " + conn);
      //添加dispathServlet
      AnnotationConfigWebApplicationContext ac = new AnnotationConfigWebApplicationContext();
      ac.register(WebMvcConfig.class);
      DispatcherServlet dispatcherServlet = new DispatcherServlet(ac);
      Wrapper wrapper = tomcat.addServlet("/", "mvc", dispatcherServlet);
      context.addServletMappingDecoded("/","mvc");
      wrapper.setLoadOnStartup(1);
      wrapper.addMapping("*");
      tomcat.start();
      tomcat.getServer().await();
  }
