1.@PathVariable
通过URI template 样式映射时，使用@PathVariable
<script type="text/javascript">
$(‘#setButton‘).click(function() { $("#removeId").val(spId); $("#toolBarForm").attr("action","/test/"+$("#id").val()); $("#toolBarForm").submit(); });
</script>
Controller层接收
@RequestMapping( value = "/test/{id}", method = RequestMethod.POST ) public String test(String removeId,@PathVariable String id,HttpServletRequest request,HttpServletResponse response,Model model) { return this.listLoad(request, response, model); }
有一个地方需要注意的是 id必须是不带符号的字符串，如果是中间带逗号的字符串，后台接收时会出错
通过在url用?挂参数来传参
<script type="text/javascript">$(‘#setButton‘).click(function() { $("#removeId").val(spId); $("#toolBarForm").attr("action","/test2?id="+$("#id").val()); $("#toolBarForm").submit(); });</script>
Controller接收
@RequestMapping( value = "/test2", method = RequestMethod.POST ) public String batchSet(String removeId,@RequestParam String id,HttpServletRequest request,HttpServletResponse response,Model model) { return this.listLoad(request, response, model); }
3.@SessionAttributes
通过在controller上加上注解，绑定HttpSession中attribute的值
@Controller @SessionAttributes({"session"}) public class TestController extends BaseController { }
绑定的方法，可以通过model.addAttribute("session",session);
取法可以通过
HttpSession.getAttribute("session");
也可以
HttpServletRequest.getSession.getAttribute("session");
4.@ModelAttribute
这一种还没怎么用过，应该是被@ModelAttribute注解过的方法会在controller的每个方法执行之前被调用一遍
public class HelloWorldController { @ModelAttribute public void populateModel(@RequestParam String abc, Model model) { model.addAttribute("attributeName", abc); } @RequestMapping(value = "/helloWorld") public String helloWorld() { return "helloWorld"; }
下面是一个具体解释@ModelAttribute的链接
