1. 引入jar包
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-core</artifactId>
<version>9.0.36</version>
</dependency>
2. 新增一个servlet
public class MyServlet extends HttpServlet {
@Override
public void service(ServletRequest req, ServletResponse res) throws ServletException, IOException {
req.setCharacterEncoding("UTF-8");
res.setCharacterEncoding("UTF-8");
String aa = req.getParameter("aa");
System.out.println(aa);
PrintWriter out = res.getWriter();
res.setContentType("text/html; charset=utf-8");
out.write("访问成功");
out.flush();
out.close();
System.out.println("访问成功！");
}
}
3.tomcat 调用
public void start(String hostname, Integer port) throws Exception{
Tomcat tomcat = new Tomcat();
Server server = tomcat.getServer();
Service service = server.findService("Tomcat");
Connector connector = new Connector();
connector.setPort(port);
Engine engine = new StandardEngine();
engine.setDefaultHost(hostname);
Host host = new StandardHost();
host.setName(hostname);
String contextPath = "";
Context context = new StandardContext();
context.setPath(contextPath);
context.addLifecycleListener(new Tomcat.FixContextListener());
host.addChild(context);
engine.addChild(host);
service.setContainer(engine);
service.addConnector(connector);
tomcat.addServlet(contextPath, "dispatcher", new MyServlet());
context.addServletMappingDecoded("/*", "dispatcher");
tomcat.start();
tomcat.getServer().await();
}
