Swagger无法渲染 Finished Loading Resource Information. Rendering Swagger UI...

问题：无法渲染swagger ui页面，本来swagger页面是正常加载的，但突然不能加载了

修改前代码：

        @ApiOperation(value = "管理员登录接口", notes = "提供用户名和密码")
	@RequestMapping(value = "login.do", method = RequestMethod.POST,consumes="text/html;charset=utf-8",produces="application/json;charset=utf-8")
	@ResponseBody
	public ServiceResponse<User> login(
			@ApiParam(value = "用户名", required = true)@RequestParam("username") String username, 
			@ApiParam(value = "登录密码", required = true)@RequestParam("password") String password, 
			boolean rememberMe){
		ServiceResponse<User> response = iUserService.login(username, password, rememberMe);
		Session session = SecurityUtils.getSubject().getSession();
		if (response.isSuccess()) {
			session.setAttribute(Const.CURRENT_USER, response.getData());
		}
		return response;
	}

原因：该接口有个boolean参数没有添加@RequestParam注解，随后加上该注解，swagger又可以加载了

	@ApiOperation(value = "管理员登录接口", notes = "提供用户名和密码")
	@RequestMapping(value = "login.do", method = RequestMethod.POST,consumes="text/html;charset=utf-8",produces="application/json;charset=utf-8")
	@ResponseBody
	public ServiceResponse<User> login(
			@ApiParam(value = "用户名", required = true)@RequestParam("username") String username, 
			@ApiParam(value = "登录密码", required = true)@RequestParam("password") String password, 
			@ApiParam(value = "记住我", required = false)@RequestParam(value = "rememberMe", defaultValue = "false") boolean rememberMe){
		ServiceResponse<User> response = iUserService.login(username, password, rememberMe);
		Session session = SecurityUtils.getSubject().getSession();
		if (response.isSuccess()) {
			session.setAttribute(Const.CURRENT_USER, response.getData());
		}
		return response;
	}
