SpringBoot整合Servlet和Filter和Listener组件详解

@WebServlet("/my")
public class MyServlet extends HttpServlet {
    @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 {
        System.out.println("name>>>" + req.getParameter("name"));
    }
}

@WebFilter("/*")
public class MyFilter implements Filter {
    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        System.out.println("MyFilter>>>init");
    }

    @Override
    public void destroy() {
        System.out.println("MyFilter>>>doFilter");
    }

    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
        System.out.println("MyFilter>> >destroy");
    }
}

@WebListener
public class MyListener implements ServletRequestListener {
    @Override
    public void requestDestroyed(ServletRequestEvent sre) {
        System.out.println("MyListener>>> requestDestroyed");
    }

    @Override
    public void requestInitialized(ServletRequestEvent sre) {
        System.out.println("MyListener>> > requestInitialized");
    }
}

@SpringBootApplication
@ServletComponentScan
public class TestspringbootApplication {

    public static void main(String[] args) {
        SpringApplication.run(TestspringbootApplication.class, args);
    }

}
