controller .java
@Controller
public class MyController {
@RequestMapping(value="/my")
public String getMyHomePage(Model model) {
LinkedList<String> listOfMyFriends = new LinkedList<String>();
listOfMyFriends.add("friend1");
listOfMyFriends.add("friend2");
listOfMyFriends.add("friend3");
listOfMyFriends.add("friend4");
model.addAllAttributes(listOfMyFriends);
return "my";
}
}
将return
前一行替换为
model.addAttribute("listOfMyFriends", listOfMyFriends);
当你做一个model.addAllAttributes(listOfMyFriends);
It Copies all attributes in the supplied Collection into this Map, using attribute name generation for each element.
属性名的生成使用方法:Conventions.getVariableName()
因此,如果您不确定generated attribute name
将是什么,请使用
model.addAttribute("listOfMyFriends", listOfMyFriends);
这样你就可以使用键"listOfMyFriends"
将listOfMyFriends添加到模型中,如下所示:
model.addObject("listOfMyFriends ", listOfMyFriends );
