word文档放在 src/main/resources/template

下载接口 使用 ClassPathResource 读取 

InputStream fileStream = null;
try {
    ClassPathResource classPathResource = new ClassPathResource(filePath);
    // 资源路径 
    // file:/xxx/target/classes/template/abc.docx

    String url = classPathResource.getURL().toString();
    fileStream = classPathResource.getInputStream();
    byte[] bytes = IoUtil.readBytes(fileStream);
    return bytes;
}finally{
    IoUtil.close(fileStream);
}


src 和 target里的 文件大小不一样 

/src/main/resources/template/abc.docx
/target/classes/template/abc.docx

word文档里 有占位符 {{reportCode}}
编译时会做占位符替换 ，导致乱码

加上 docx 配置后 ok 
<nonFilteredFileExtension>docx</nonFilteredFileExtension>
