简介
PoiReadObjUtil 在某些情况下无法读取 jar 包中的 excel 文件的解决方案.
问题概述
// 从 resources 的相对路径中获取xls文件信息
List<Map<String, Object>> data = PoiReadObjUtil.readExcelToMap(ReadFileUtil.read("file/test.xls", getClass()));
// 收到异常提示: 无法识别此excel文件的类型。可能是文件类型错误，或者maven编译问题。
解决方案
因为文件是放在源码目录中,打包到jar文件内的,因此可以排除文件本身的问题.
经查,发现是 maven-resources-plugin 插件造成的文件编码问题,需要修改pom.xml:
<build>
<plugins>
......
</plugins>
<resources>
<resource>
<directory>${project.basedir}/src/main/resources</directory>
<filtering>true</filtering>
<excludes>
<exclude>**/*.woff</exclude>
<exclude>**/*.ttf</exclude>
<exclude>**/*.eot</exclude>
<exclude>**/*.svg</exclude>
<exclude>**/*.zip</exclude>
<exclude>**/*.xls</exclude>
<exclude>**/*.xlsx</exclude>
<exclude>**/*.crt</exclude>
<exclude>**/*.p8</exclude>
</excludes>
</resource>
<resource>
<directory>${project.basedir}/src/main/resources</directory>
<filtering>false</filtering>
<includes>
<include>**/*.woff</include>
<include>**/*.ttf</include>
<include>**/*.eot</include>
<include>**/*.svg</include>
<include>**/*.zip</include>
<include>**/*.xls</include>
<include>**/*.xlsx</include>
<include>**/*.crt</include>
<include>**/*.p8</include>
</includes>
</resource>
</resources>
</build>
