Obba 介绍
Obba 提供了将Excel的表单映射到Java类的类库，通过Obba可以简单的在Java代码中创建显示Excel的图形程序，主要特性包括：
- Loading of arbitrary jar or class files at runtime through an Excel worksheet function.
- Instantiation of Java objects, storing the object reference under a given object label.
- Invocation of methods on objects referenced by their object handle, storing the handle to the result under a given object label.
- Asynchronous method invocation and tools for synchronization, turning your spreadsheet into a multi-threaded calculation tool.
- Allows arbitrary number of arguments for constructors or methods (avoids the limitation of the number of arguments for Excel worksheet functions).
- Serialization and de-serialization (save Serializable objects to a file, restore them any time later).
- All this though spreadsheet functions, without any additional line of code (no VBA needed, no additional Java code needed).
