要将证书文件后缀添加到resource文件夹内范围，添加打包文件后缀（include）
添加maven配置:
<resources>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.xml</include>
<include>**/*.p12</include>
<include>**/*.properties</include>
</includes>
<filtering>true</filtering>
</resource>
<resource>
<directory>src/main/webapp/WEB-INF</directory>
<includes>
<include>**/*.xml</include>
<include>**/*.properties</include>
</includes>
<filtering>true</filtering>
</resource>
</resources>
maven打包证书文件后，会对证书文件修改，禁止修改：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>2.6</version>
<configuration>
<encoding>UTF-8</encoding>
<!-- 过滤后缀为pem、pfx的证书文件 -->
<nonFilteredFileExtensions>
<nonFilteredFileExtension>pem</nonFilteredFileExtension>
<nonFilteredFileExtension>pfx</nonFilteredFileExtension>
<nonFilteredFileExtension>p12</nonFilteredFileExtension>
</nonFilteredFileExtensions>
</configuration>
</plugin>
