先看代码：

@RequestMapping(value="manager")
@Controller("managerController")
public class ManagerController {

    
    /**
     * 后台用户登录
     * @param request
     * @param emp
     * @return
     */
    @RequestMapping(params="login" , method={RequestMethod.POST})
    public String login(HttpServletRequest request , Employe emp){
        
        request.getSession().setAttribute(SystemConstant.MANAGER, emp);
        return "redirect:index.jsp";
    }
    
    
    /**
     * 后台用户退出
     * @param request
     * @return
     */
    @RequestMapping(params="logout" , method={RequestMethod.POST,RequestMethod.GET})
    public String logout(HttpServletRequest request){
        
        request.getSession().removeAttribute(SystemConstant.MANAGER);
        return "redirect:login.html";
    }
}

类上面有配置RequestMapping，访问路径为 manager ，方法上面这次配置的是params，值为login和logout。
页面发起访问路径由 类的访问名称 + 方法的访问名称/参数名称

页面请看form的action ，如果是get方法或者超链接也是一样，当然要记得添加参数

<form class="form-horizontal" action="manager?login" method="post">
                    <div class="form-group">
                      <label class="control-label col-lg-3" for="inputEmail">账号</label>
                      <div class="col-lg-9">
                        <input type="text" class="form-control" id="inputEmail" placeholder="账号" name="empName">
                      </div>
                    </div>
                    <div class="form-group">
                      <label class="control-label col-lg-3" for="inputPassword">密码</label>
                      <div class="col-lg-9">
                        <input type="password" class="form-control" id="inputPassword" placeholder="密码" name="empPassword">
                      </div>
                    </div>
                        <div class="col-lg-9 col-lg-offset-2">
                            <button type="submit" class="btn btn-danger">登陆</button>
                            <button type="reset" class="btn btn-default">重置</button>
                        </div>
                    <br />
                  </form>
