问题
使用的是spring-boot项目，自然而然的使用spring-boot-maven-plugin插件对项目进行打包操作，由于项目中docx文档作为模板文档，之前一直运行出错，去看了下target下面的这个文档(有的时候FileNotFoundException或者出现各种文件错误，去看target还是比较真实的)，然后打开一看，全乱码了，如图：
正常的应该为: 
解决过程
实验了各种网上的方案，我搜索到的基本都是说maven或者spring-boot-maven-plugin导致excel文档出现问题的。
1. 修改编码为UTF-8
<plugin>
<!--打包成可执行jar-->
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<jvmArguments>-Dfile.encoding=UTF-8</jvmArguments>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
2. 使用另外一种打包方案
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<mainClass>自己的主类(含有main方法的类)的全类名</mainClass>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
3. 查看自己项目是否设置为UTF-8，以及对应所有的文件是否设置为UTF-8
看了，全是UTF-8
以上方法全部试验愣是没解决。
最后拿着一个项目作比对，发现了一个小区别：
正常的项目(maven项目，不是spring-boot类型的项目，打包使用的是maven-compiler-plugin这个插件)的resource配置有个区别：
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.xml</include>
<include>**/*.properties</include>
<include>**/*.json</include>
<include>**/*.yml</include>
<include>**/*.js</include>
<include>**/*.html</include>
<include>**/*.csv</include>
<include>**/*.sqlite</include>
<include>**/*.docx</include>
<include>**/*.zip</include>
</includes>
</resource>
非正常项目的resource(这个是maven的spring-boot项目，使用：spring-boot-maven-plugin这个插件)为:
<resource>
<directory>src/main/resources</directory>
<filtering>true</filtering>
<includes>
<include>**/*.xml</include>
<include>**/*.properties</include>
<include>**/*.json</include>
<include>**/*.yml</include>
<include>**/*.js</include>
<include>**/*.html</include>
<include>**/*.css</include>
<include>**/*.svg</include>
<include>**/*.jpg</include>
<include>**/*.jpeg</include>
<include>**/*.png</include>
<include>**/*.ico</include>
<include>**/*.woff2</include>
<include>**/*.txt</include>
<include>**/*.xlsx</include>
<include>**/*.xls</include>
<include>**/*.docx</include>
</includes>
<excludes>
<exclude>env/*.properties</exclude>
</excludes>
</resource>
他俩的区别就是，不正常的这个resource配置多了个：<filtering>true</filtering>这个选项
结果去除掉true之后，正常了。去除之后的resource为:
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.xml</include>
<include>**/*.properties</include>
<include>**/*.json</include>
<include>**/*.yml</include>
<include>**/*.js</include>
<include>**/*.html</include>
<include>**/*.css</include>
<include>**/*.svg</include>
<include>**/*.jpg</include>
<include>**/*.jpeg</include>
<include>**/*.png</include>
<include>**/*.ico</include>
<include>**/*.woff2</include>
<include>**/*.txt</include>
<include>**/*.xlsx</include>
<include>**/*.xls</include>
<include>**/*.docx</include>
</includes>
<excludes>
<exclude>env/*.properties</exclude>
</excludes>
</resource>
总结
我也不知道什么原因。搜索了一下大致解释如下：
resource的filtering配置：
主要用来替换项目中的资源文件（*.xml、*.properties）当中的${...}，比如${db.url}，
那么如果配置了db.url=aaa的话，在项目编译的时候，就会自动的把${db.url}替换为aaa
也就是说，可能是在打包的时候，docx里面有好多${xxxxx}形式的东西，然后导致出现替换的问题，但是我查看了下文档，
好像也不是那么一回事，具体原因不明白，上面这个原因只是一个猜测。
头疼问题
如果去除掉了true 或者设置为false ,那么随之而来的一个问题就是：你的maven打包多环境替换properteies将会失效。 想起来一句话：此事古难全，但愿人长久!
补充
今天实验了下，有个解决方案，原来是如此的简单，我竟然没有想到：解决方案就是，多写几个resource标签就行,所有的二进制形式的文件，或者乱码的文件都放置在不需要替换的resource标签下面 例如：
<resources>
//这个是java的文件操作，不需要过滤
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.xml</include>
<include>**/*.properties</include>
</includes>
</resource>
//这个是真正的资源文件，需要过滤的
<resource>
<directory>src/main/resources</directory>
<filtering>true</filtering>
<includes>
<include>**/*.xml</include>
<include>**/*.properties</include>
<include>**/*.json</include>
<include>**/*.yml</include>
<include>**/*.js</include>
<include>**/*.html</include>
<include>**/*.css</include>
<include>**/*.svg</include>
<include>**/*.jpg</include>
<include>**/*.jpeg</include>
<include>**/*.png</include>
<include>**/*.ico</include>
<include>**/*.woff2</include>
<include>**/*.txt</include>
<include>**/*.xlsx</include>
<include>**/*.xls</include>
</includes>
<excludes>
<exclude>env/*.properties</exclude>
</excludes>
</resource>
//这个也是资源文件，不需要过滤的，可以单独拉出来设置filtering为false
<resource>
<directory>src/main/resources</directory>
<filtering>false</filtering>
<includes>
<include>**/*.docx</include>
</includes>
</resource>
</resources>
