我曾经让它工作正常,不知何故经过一些开发我意识到HTML元素_method不是自动在页面上创建的,因此REST不起作用。
下面是我的web.xml,其中包含HiddenHttpMethodFilter
。

我尝试了什么
已更新
我的jsp部分
<html:form modelAttribute="user" id="user-form" formUrl="/user">
form.tag将其转换为Spring表单
<form:form modelAttribute="${modelAttribute}" id="${id}"
action="${processedFormUrl}" class="form-horizontal"
target="${target}" method="post">
<fieldset>
<jsp:doBody />
</fieldset>
</form:form>
答案 0 :(得分:0)
只有当你的表单方法不是post,即它的PUT / DELETE时,才需要HiddenHttpMethodFilter,在这种情况下,spring会自动使用正确的表单方法添加_method隐藏字段。
如果你想让一个看跌请求改变method="put"
并且spring-form将会处理休息
<强> EDITTED 强> 我看了一下Spring FormTag的源代码,我发现了下面的
if (!isMethodBrowserSupported(getMethod())) {
assertHttpMethod(getMethod());
String inputName = getMethodParameter();
String inputType = "hidden";
tagWriter.startTag(INPUT_TAG);
writeOptionalAttribute(tagWriter, TYPE_ATTRIBUTE, inputType);
writeOptionalAttribute(tagWriter, NAME_ATTRIBUTE, inputName);
writeOptionalAttribute(tagWriter, VALUE_ATTRIBUTE, processFieldValue(inputName, getMethod(), inputType));
tagWriter.endTag();
}
protected boolean isMethodBrowserSupported(String method) {
return ("get".equalsIgnoreCase(method) || "post".equalsIgnoreCase(method));
}
因此,只有当您的表单方法没有获取/发布时,才会添加_method隐藏字段。
对于您的情况,当单击删除按钮时,您可以在子命令之前使用jquery为_method字段添加输入隐藏标记,
var input = $("<input>").attr("type", "hidden").attr("name", "_method").val("DELETE");
$('form#yoorFormID').append(input).submit();
