// 文件读写：单行完成 FileUtil.writeString("Hello Hutool", "/tmp/test.txt", CharsetUtil.UTF_8); String content = FileUtil.readUtf8String("/tmp/test.txt");
Hutool is organized into several modules, all accessible via the hutool-all artifact: 1. Date and Time Processing (DateUtil)
| Problem | Without Hutool | With Hutool (Method #) | |---------|----------------|------------------------| | Null-safe string conversion | 3 lines + ternary | 1 line (#1) | | Read file to string | 10 lines (try-with-resources) | 1 line (#11) | | POST JSON to API | 30 lines (HttpURLConnection) | 2 lines (#15, #16) | | Deep copy a bean | manual get/set every field | 1 line (#30) |
该版本修复了一系列关键问题，包括 NumberUtil.isNumber() 方法对以“L”结尾的数字的判断问题、 CharSequenceUtil.toLowerCase() 方法的拼写错误、 Money 中金额分配的错误等。
