canal的instance.properties文件里面的canal.instance.enabl

请帮忙看看连接数据库密码加密方式不生效的问题，谢谢

我的配置如下：

canal版本：

com.alibaba.otter canal.client 1.1.4

用户名和密码

canal.instance.dbUsername=canal canal.instance.dbPassword=NWF3DPxKGGs+gj/XLdi6B269CTyLemfqagQg5D0nVMgPets7Zol6toOrbGLhMByRyQzkYUHWb9moSQiWrFZppw== canal.instance.connectionCharset = UTF-8

canal.instance.enableDruid=true canal.instance.pwdPublicKey=MIIBVAIBADANBgkqhkiG9w0BAQEFAASCAT4wggE6AgEAAkEAocbCrurZGbC5GArEHKlAfDSZi7gFBnd4yxOt0rwTqKBFzGyhtQLu5PRKjEiOXVa95aeIIBJ6OhC2f8FjqFUpawIDAQABAkAPejKaBYHrwUqUEEOe8lpnB6lBAsQIUFnQI

分析了一下代码，除了上面的bean加载失败的问题，感觉这个类的加解密也有点看不懂，是不是canal.instance.enableDruid配置成true这个功能不生效； com.alibaba.druid.filter.config.ConfigTools.java AuthenticationInfo.class 为什么解密用公钥呢？ this.password = ConfigTools.decrypt(pwdPublicKey, password);
