com.objectgeneration.designer.pro_2.0.3.jar
里面包含designer-pro.jar和lib\license4j-1.3.jar
designer-pro.jar里有个pub.keys
public=xxxx
反编译designer-pro.jar
com.objectgen.designer.pro. LicenseHandler
从jar包中提取并设置 公钥
验证 签名通过后
再判断是否有expiration 字段
要注意com.objectgen.importjdbc.pro.ImportJDBCClassesPro中还有个暗桩
两处调用 i 类中方法
从features分隔提取是否有ImportDB Pro 字符串
License4J官方下载 License4J-1.5-Trial
run_demo.bat
生成公钥
只写两个值，忽略expiratio
用生成公钥替换
com.objectgeneration.designer.pro_2.0.3.jar包里designer-pro.jar中的pub.keys
注意先删掉eclipse osgi 提取com.objectgeneration.designer.pro_2.0.3.jar的生成的designer-pro.jar
