**update：** <br/>
1. 升级相关依赖
2. 依赖工具读取文件[FileInput.java](src/main/java/com/yexuejc/base/file/FileInput.java)从[FileUtil.java](src/main/java/com/yexuejc/base/util/FileUtil.java)中提取出来
3. 优化[FileUtil.java](src/main/java/com/yexuejc/base/util/FileUtil.java)
4. 优化[JwtUtil.java](src/main/java/com/yexuejc/base/util/JwtUtil.java)
