二、Servlet 的注解及容器初始化 [不推荐]

Solon 对应的相关处理，可见：《过滤器、路由拦截器、处理器、拦截器》

1、支持 Servlet 注解

• WebServlet

@WebServlet("/heihei/*")
public class HeheServlet extends HttpServlet {
    @Override
    public void service(ServletRequest req, ServletResponse res) throws ServletException, IOException {
        res.getWriter().write("OK");
    }
}

• WebFilter

@WebFilter("/demo/*")
public class DemoFilter implements Filter {
    @Override
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain filterChain) throws IOException, ServletException {
        res.getWriter().write("Hello，我把你过滤了");
    }
}

2、支持 ServletContainerInitializer 配置

@Configuration
public class DemoConfiguration implements ServletContainerInitializer{
    @Override
    public void onStartup(Set<Class<?>> set, ServletContext servletContext) throws ServletException {
        //...
    }
}
