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);
}

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");

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
