我正在尝试使用弹簧控制器将简单列表值打印到选择框。它使用
成功返回所有值${test}
但是当我尝试这个时它不起作用。解决方案将不胜感激。
控制器
@RequestMapping(value="/flight", method = RequestMethod.GET)
public ModelAndView homePage(CountryCodes country) {
//model.addAttribute("userName", user.getUserName());
/*List<CountryCodes> countryCodes = userService.getCountryCodes();
model.addAttribute("codes", countryCodes);*/
ModelAndView mv= new ModelAndView("FlightDetails");
List<String> test = new ArrayList<String>();
test.add("Human Resources");
test.add("Finance");
test.add("Admin");
test.add("Quality Assurance");
test.add("Products");
mv.addObject("test", test);
return mv;
}
在jsp中选择框
${test}
<form:select path="country" class="form-control">
<form:options items="${test}" class="form-control"/>
</form:select>
答案 0 :(得分:0)
您是否包含spring:form
taglib参考?这种方式对我有用:
控制器:
@RequestMapping(value="/flight", method = RequestMethod.GET)
public ModelAndView homePage(CountryCodes country) {
//model.addAttribute("userName", user.getUserName());
/*List<CountryCodes> countryCodes = userService.getCountryCodes();
model.addAttribute("codes", countryCodes);*/
ModelAndView mv= new ModelAndView("FlightDetails");
List<String> test = new ArrayList<String>();
test.add("Human Resources");
test.add("Finance");
test.add("Admin");
test.add("Quality Assurance");
test.add("Products");
mv.addObject("test", test);
mv.addObject("country", country);
return mv;
}
JSP:
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<html>
<head>
<title>Select options from controller</title>
</head>
<body>
<h1>Select options from controller</h1>
${test}
<form:select path="country" class="form-control">
<form:options items="${test}" class="form-control"/>
</form:select>
</body>
</html>
