maven 資源過濾：讓 Maven 能解析資源文件中的標識符，替換其中的配置（例如： ${} ）信息為實際的值
問題現(xiàn)象
maven 打包后，target下相應的pdf文件異常，手動打開提示文件損壞，查看文件詳情發(fā)現(xiàn)文件大小變了
以下摘自maven文檔
Warning: Do not filter files with binary content like images! This will most likely result in corrupt output.
If you have both text files and binary files as resources it is recommended to have two separated folders. One folder src/main/resources (default) for the resources which are not filtered and another folder src/main/resources-filtered for the resources which are filtered.
也就是說二進制文件不能過濾，要排除需要打包的二進制文件。
解決方案
方案一：
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<configuration>
<nonFilteredFileExtensions>
<nonFilteredFileExtension>pdf</nonFilteredFileExtension>
</nonFilteredFileExtensions>
</configuration>
</plugin>
方案二：
<resources>
<resource>
<!--排除pdf，不打包到classpath下，自然就不會過濾-->
<directory>src/main/resources</directory>
<filtering>true</filtering>
<excludes>
<exclude>**/*.pdf</exclude>
</excludes>
</resource>
<resource>
<!--將pdf打包到classpath下，但是不進行資源過濾-->
<directory>src/main/resources</directory>
<filtering>false</filtering>
<includes>
<include>**/*.pdf</include>
</includes>
</resource>
</resources>
