我已经修复了您的代码。
控制者
我使用
initValues()方法来填充
model值。
我也
@RequestParam List<String> searchValues向
handleFileUpload()方法添加了参数。
import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.ModelAttribute;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.RequestParam;import org.springframework.web.multipart.MultipartFile;import java.util.Arrays;import java.util.List;@Controllerpublic class CustomerDataController { private static final String SEARCH_TYPES = "searchTypes"; @ModelAttribute public void initValues(Model model) { model.addAttribute(SEARCH_TYPES, Arrays.asList("Search A", "Search B")); } @RequestMapping(value = "/upload", method = RequestMethod.GET) public String displayUpload() { return "upload"; } @RequestMapping(value = "/userFile", method = RequestMethod.POST) public String handleFileUpload(@RequestParam("myFile") MultipartFile file, @RequestParam List<String> searchValues) { // here you can use searchValues and file return "result"; }}upload.html
我固定
<label th:text="#{${search}}"></label>到<labelth:text="${search}"></label>。我也固定
<form>和
<input type="checkbox">标签。
