springboot配置嵌入式servlet容器的方法

server.tomcat
server.tomcat.connection-timeout=  连接超时时间
server.tomcat.uri-encoding=UTF-8 修改编码

@Bean
 public ConfigurableServletWebServerFactory configurableServletWebServerFactory(){
 TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();//这里是一个工厂
 factory.setPort(8088);//修改端口号
 //factory.setContextPath("/lanqiao518");
 return factory;
 }

public class MyServlet extends HttpServlet {//写好servlet下一步给他添加进容器中
 @Override
 protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
  doPost(req,resp);
 }

 @Override
 protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
  resp.setContentType("text/html;charset=utf-8");
  resp.setCharacterEncoding("utf-8");
  resp.getWriter().write("hello 你好");
 }
}

public class Mylistener implements ServletContextListener {
 @Override
 public void contextInitialized(ServletContextEvent sce) {

  System.out.println("项目启动了————————————————————————");
 }

 @Override
 public void contextDestroyed(ServletContextEvent sce) {
  System.out.println("项目关闭了————————————————————————");
 }
}

public class MyFilter implements Filter {
 @Override
 public void init(FilterConfig filterConfig) throws ServletException {

 }

 @Override
 public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
  System.out.println("MyFilter拦截了----------------------");
  filterChain.doFilter(servletRequest,servletResponse);//然后放行
 }

 @Override
 public void destroy() {

 }
}

@Configuration
public class MyServletConfig {
 //将自己写的servlet添加进容器
@Bean
 public ServletRegistrationBean myServlet(){
  ServletRegistrationBean registrationBean=new ServletRegistrationBean(new MyServlet(),"/my");//将自己写的servlet添加进来，并给一个访问路径
  return registrationBean;
 }
}

@Bean
public ServletListenerRegistrationBean myListener() {
 ServletListenerRegistrationBean listenerRegistrationBean = new ServletListenerRegistrationBean(new Mylistener());//传一个自己写的监听器即可
 return listenerRegistrationBean;
}

@Bean
public FilterRegistrationBean myFilter(){
 FilterRegistrationBean filterRegistrationBean=new FilterRegistrationBean(new MyFilter(),myServlet());//传一个自己写的Filter 和你要拦截的servlet 可以是多个
 return filterRegistrationBean;
}
