我正在Jquery
使用Spring MVC
。
我有index.jsp
:
<html>
<head>

<script>
$(document).ready(function() {
$("input").keyup(function() {
$.ajax({
url : "myController",
type: "POST",
data: $("#name").val(),
success : function(result) {
alert(result);
}
});
});
});
</script>
</head>
<body>
<form>
<div class="row">
<div class="col-sm-12">
<label for="name">Name:</label>
</div>
<div class="col-sm-1">
<input type="text" class="form-name" id="name" placeholder="Paolo">
</div>
</div>
</form>
</body>
</html>
正如您在输入框中插入字母时所看到的,我使用jQuery运行$ajax
。
我的HTTP POST请求是已发送的,但我有400错误。
这是我简单的Controller类:
@Controller
public class MyController {
@RequestMapping(value="/myController", method = RequestMethod.POST)
@ResponseBody
public String getData(@RequestParam(value="name") String name) {
return name;
}
}
我的Spring MVC的DispatcherServlet是相关的。 我怎么解决?
答案 0 :(得分:1)
A 400表示请求格式错误。换句话说,客户端发送到服务器的数据流不遵守规则。
你的ajax电话会是
$.ajax({
url : "myController",
type: "POST",
data:{"name": $("#name").val()},
success : function(result) {
alert(result);
}
});
