1.Below是我在index.jsp中的ajax调用
<script type="text/javascript">
$(document).ready(function(){
$('#buttonDemo1').click(function(){
$.ajax({
method: "GET",
url: '${pageContext.request.contextPath}/ajax/demo1',
success: function(result){
$('#result1').html(result);
},
error: function(response){
console.log("error");
}
});
});
});
</script>
2.Below是控制器的代码
@Controller
@RequestMapping("/ajax")
public class AjaxController {
@RequestMapping(method = RequestMethod.GET)
public String index() {
return "ajax/index";
}
@RequestMapping(value="/demo1", method = RequestMethod.GET)
@ResponseBody
public String demo1() {
return "Demo 1";
}
}
3。以下是调度员的代码

define an explicit mapping for it.

我不知道什么是错的，每当我在ajax中遇到控制器的路径时，我得到＆＃34; GET http://localhost:8080/ajax/demo1 404（Not Found）＆ ＃34;错误。请帮帮我解决我错的地方。我尝试了很少的解决方案，但他们没有解决问题。
