我正在开发一个新的库管理软件,其中包括spring boot,angular js和MongoDB作为后端。我想在MongoDB上使用该应用程序执行crud操作,为此,我引用了一些开源项目,我可以成功执行创建和读取操作,但不能执行删除和更新操作,所以如何执行我还对删除进行了一些更改更新,但无法执行,所以告诉我必须执行更改才能执行删除。我在mybooks.html中添加了这个我自己的但是元素没有删除。因为在mybooks.html和hello中做了一些更改.js用于删除操作但该元素未删除

将DELETE方法更改为GET,在pathvariable中传递id param,通过它从DB查找实体。然后删除实体。
