要学会使用ASM的最佳方式是编写一个Java源文件就相当于你想生成，然后使用字节码纲要插件Eclipse的ASMifier模式（或ASMifier工具）看到相当于ASM代码是什么。如果你想实现一个级变压器，写两个Java源文件（改造前，后），并使用插件的比较视图ASMifier模式比较等效的ASM代码。-The best way to learn to use ASM is to write a Java source file that is equivalent to what you want to generate and then use the ASMifier mode of the Bytecode Outline plugin for Eclipse (or the ASMifier tool) to see the equivalent ASM code. If you want to implement a class transformer, write two Java source files (before and after transformation) and use the compare view of the plugin in ASMifier mode to compare the equivalent ASM code.
