只实现最简单功能,自动生成setter,getter当bean中属性较多时可以节省时间:
usage: java javabeanmaker aaa.txt bbb
1. aaa.txt is the text file in following style,you can get a example–jeru.txt in attachment
======================
int id
string name
int age
======================
2 bbb is the file name of your javabean without .java,so if you want a test.java
just type "java javabeanmaker aaa.txt test"
================= jeru.txt ==========================
int id
string name
int age
================= javabeanmaker.java ================
