@Controller
@RequestMapping("/param")
public class ParamController {
        @RequestMapping(path = "testServlet")
    private String testServlet(HttpServletRequest servletRequest, HttpServletResponse servletResponse){
        System.out.println("执行....");
        String contextPath = servletRequest.getContextPath();
        System.out.println("contextPath:" +contextPath);

        String method = servletRequest.getMethod();
        System.out.println("method:" +method);

        String encoding = servletRequest.getCharacterEncoding();
        System.out.println("encoding:" +encoding);

        HttpSession session = servletRequest.getSession();
        System.out.println("session:" +session);

        ServletContext servletContext = session.getServletContext();
        System.out.println("servletContext:" +servletContext);

        System.out.println("servletResponse:" +servletResponse);
        return "success";

    }
}

 

 

就是这么简单，传入参数就行
