一。在添加城市页面添加验证信息，修改取消按钮路径。（提示文本框不能为空，文本框变为红色）
1。 添加验证信息
①在WEB-INF/jsp/manager/city/addCity.jsp中修改
<div class="box-content">
<form:form modelAttribute="cityForm" action="addCity" method="post">
<div class="alert alert-info">${message}<form:errors path="*"></form:errors></div>
<table class="table table-bordered responsive">
②在CityForm.java中添加
@NotEmpty(field="城市名称", message="{errors.required}")
private String cityName;
③在CityController.java中添加
@RequestMapping(value = "addCity", method = RequestMethod.POST)
public String executeAddCity(Model model, @Valid @ModelAttribute("cityForm") CityForm cityForm, BindingResult results) throws SQLException, IOException {
if (results.hasErrors()) {
log.info("内容验证出错");
List<Item> provinceList = itemListComponent.getProvinceList();
model.addAttribute("provinceList", provinceList);
return "manager/city/addCity";}
log.info("添加城市");
boolean result = cityService.addCity(cityForm);
if(!result) {
throw new SQLException("城市添加失败！");
}
2. 修改取消按钮路径
在WEB-INF/jsp/manager/city/addCity.jsp中修改
<a href="initMenu" class="btn btn-danger">取 消</a>

<link href="css/common.css" rel="stylesheet"> //line28
<td style="background-color: #f9f9f9;">城市名称</td>
