Because of his agreement maven greater than configuration, you could meet us after we write the configuration file, the problem can not be exported or entered into force.
Solution :
<!--在build中配置resources,来防止我们资源导出失败的问题-->
<build>
<resources>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>true</filtering>
</resource>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>true</filtering>
</resource>
</resources>
</build>
3. IDEA operations
4. solve problems encountered
(1) Maven 3.6.2 version problem arises
Solution : downgraded to 3.6.1
(2) the Tomcat flash back

(3) IDEA to be duplicated in every Maven
solution : to configure the default configuration of the global IDEA
(4) maven default web.xml version of the problem web project
Solution : Replace webapp4.0 version and tomcat consistent
configuration as follows:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
version="4.0"
metadata-complete="true">
</web-app>
