这是我的jquery脚本。
<!-- language: lang-js -->
script type="text/javascript" src="/**/resources/scripts/jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
var url="/**/showContract";
$("button").click(function(){
alert(url);
$.get(url,null, function (data,success) {
alert("hi...");
//alert(data);
//alert(success);
});
});
});
</script>
和我的控制器方法..
<!-- language: lang-html -->
@RequestMapping(value = "/showContract",method =RequestMethod.GET,produces="text/plain; charset=utf-8")
@ResponseBody
public String getContract() {
System.out.println("j.ja.jajj");
String message="oye ther";
String message0[]={"hello","world"};
return message;
}
和我的servlet-context
<!-- language: lang-html -->

我浏览了论坛以获得各种答案。他们都谈到我们应该如何向控制器方法添加@Responsebody注释，以便返回字符串。但是尽管如此，我收到了这个错误。当SOP输出我给出的字符串时，呼叫到达控制器。据我所知，这个错误表明响应头有问题，但我不知道为什么？我已经注释了它，并且还提到了“produce ='text / plain'”。
任何人都可以提供任何线索吗？
有些人建议添加
<mvc:annotation-driven/>
