<button onclick="window.location.href='/status'">Load</button>
如果你的jsp有表格你可以提交表格到action ='/ status'url

If you need to display the same JSP page, then regardless actual URL, you can use something like: 如果您需要显示相同的JSP页面，那么无论实际的URL如何，您都可以使用以下内容：
<button onclick="window.location.href=window.location.href;">Load</button>
Also it can be slightly shorter, but please note, that it won't work for old IE versions. 它也可以稍短，但请注意，它不适用于旧的IE版本。
<button onclick="window.location.reload();">Load</button>

So you need to make another GET request to the same URI. 所以你需要对同一个URI发出另一个GET请求。 A clean way that doesn't depend on JavaScript is using a form: 一种不依赖于JavaScript的干净方式是使用表单：
<form>
<button type="submit">Load</button>
</form>
If you dont't specify an action-attribute on the form element, the GET request is made to the same URI as the current page (in HTML5). 如果您没有在表单元素上指定action-attribute，则GET请求将与当前页面（在HTML5中）的URI相同。 In HTML4 the action attribute is required, so you can use the following: 在HTML4中，action属性是必需的，因此您可以使用以下内容：
<form action="<c:url value="/status" />">
<button type="submit">Load</button>
</form>
