[Java知识库]学习记录541@Java代码启动Tomcat及手动注册servlet

创建maven项目并引入依赖

<dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-core</artifactId>
            <version>10.0.8</version>
        </dependency>

代码TomcatTest

public class TomcatTest {
    public static void main(String[] args) throws LifecycleException {
        Tomcat tomcat = new Tomcat();
        Connector connector = new Connector();
        connector.setPort(8081);
        connector.setURIEncoding("UTF-8");
        tomcat.getService().addConnector(connector);

//        http://localhost:8081/project/index.html
        MyServlet myServlet = new MyServlet();
        Context project = tomcat.addContext("project", null);
        tomcat.addServlet(project,"myServlet",myServlet);

        project.addServletMappingDecoded("/index.html","myServlet");

        tomcat.start();
        tomcat.getServer().await();//阻塞
    }
}

代码MyServlet

public class MyServlet extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        super.doGet(req, resp);
        System.out.println("------------servlet-----------");
    }
}
