Javaweb Servlet获取请求类型

@Override
public void service(ServletRequest req, ServletResponse res) throws ServletException, IOException {
	System.out.println("this is hello servlet");
	//HttpServletRequest是 ServletRequest的子类
	HttpServletRequest httpServletRequest = (HttpServletRequest) req;
	// getMethod()方法可以获取当前的请求类型
	String method = httpServletRequest.getMethod();
	System.out.println("请求类型:  "+ method);
}

• HttpServletRequest是ServletRequest 的子类,子类有getMethod()方法可以获取当前的请求类型
