你可以解释一下为什么DELETE方法(Edit.js中的store.remove())会抛出400 Bad请求。其他方法效果很好。在标头请求网址似乎没问题" http://localhost:8080/Diary/rest/notes/22?_dc=1461837327580"。
我知道问题出在DELETE方法的有效负载中,store.remove()包含ID作为有效负载。如何禁用它并发送没有正文的DELETE方法,因为ID已经在URL中

//get reference to the form
var detailView = btn.up('editForm');
//get the form inputs
var data = detailView.getValues();

你身上没有 HttpMethod.DELETE 。
这在RFC中没有明确说明,但如果您在 delete 方法中有一个代理服务器将拒绝该主体。 Spring会降低标准,并会使用错误请求拒绝您的查询。
删除正文以及解决问题的答案。

如果TestStore是你正在使用的商店,我猜你的问题就在这里:
actionMethods: { create: 'POST', read: 'GET', update: 'PUT', destroy: 'GET' },
我不认识@DELETE注释,所以我不是100%肯定,但如果你的控制器期待DELETE,而你发送GET,那可以解释400错误。
