解决SpringBoot下delete请求不可用There was an unexpected error (type=Method Not Allowed, status=405).

1、页面提交delete请求，出现Whitelabel Error Page错误

<button th:attr="[e-mail]{/emp/}+${emp.id}" class="btn btn-sm btn-danger deleteBtn">删除</button>

<form id="deleteEmpForm"  method="post">
	<input type="hidden" name="_method" value="delete"/>
</form>

<script>
	$(".deleteBtn").click(function(){
				//删除当前员工的
			   $("#deleteEmpForm").attr("action",$(this).attr("del_uri")).submit();
				return false;
			});
</script>

解决办法

只需要在SpringBoot配置中【application.properties】配置：

spring.mvc.hiddenmethod.filter.enabled=true
