IDEA+SpringMVC+Gradle 配置Servlet报错问题解决

在web.xml文件下和的标签中报错如下信息。

1.

Servlet should have a mapping less... (Ctrl+F1) 
Inspection info: Checks if all servlets have mappings

2.

Cannot resolve Servlet 'login' less... (Ctrl+F1) 
Inspection info: This inspection lets you spot the following problems that might occur in descriptors that are used to deploy your Web Module to a server:
References to the non-instantiable classes
References to the classes that do not extend required class
References to classes with inappropriate scope
Empty tag and attribute values
Tag and attribute values that do not match required pattern (e.g. Java Identifiers)
Tags that do not include required children tags or attributes
Tags that define objects with duplicate names

解决如下：

点击file->project  structure->Modules->web,在Deployment Descriptors视窗下点击右边的加号选择web.xml,找到web.xml的位置即可,再点击apply->ok。

 

错误消失。
