Springmvc构造RESTful
web.xml

    <servlet>        <servlet-name>annomvc</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>        <init-param>            <param-name>contextConfigLocation</param-name>            <param-value>classpath*:resource/spring/springmvc.xml</param-value>        </init-param>        <load-on-startup>2</load-on-startup>    </servlet>    <servlet-mapping>        <servlet-name>annomvc</servlet-name>        <url-pattern>/</url-pattern>    </servlet-mapping>

类头：

@Controller@RequestMapping("/maintain/bms/")public class BmsPressController {

写法1：

    @RequestMapping(value="press_insert_load/{id}",method=RequestMethod.GET)    public ModelAndView load(@PathVariable("id") int id,HttpServletRequest request){        ModelAndView modelAndView = new ModelAndView();        BmsPress bmsPress = bmsPressService.selectById(id);        request.setAttribute("bmsPress", bmsPress);        modelAndView.setViewName("/maintain/bms/press_insert_load");        return modelAndView;    }

写法2：

    @RequestMapping(value="press_insert_load/{id}",method=RequestMethod.GET)    public String load(@PathVariable("id") int id,HttpServletRequest request){        BmsPress bmsPress = bmsPressService.selectById(id);        request.setAttribute("bmsPress", bmsPress);        return "/maintain/bms/press_insert_load";    }

上面两种写法访问方式都是 ：/maintain/bms/press_insert_load/21

下面这种访问方式：/maintain/bms/press_insert_load.do?id=21

    @RequestMapping(value="press_insert_load",method=RequestMethod.GET)    public String load(@RequestParam int id,HttpServletRequest request){        BmsPress bmsPress = bmsPressService.selectById(id);        request.setAttribute("bmsPress", bmsPress);        return "/maintain/bms/press_insert_load";    }

效果：
