啥时候开源分库分表层？

使用TDDL报下面错误是什么原因
Nested in org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mysqlTddlDataSource' defined in file [D:\work\aaa\target\classes\biz\persistence.xml]: Invocation of init method failed; nested exception is java.lang.RuntimeException: subscribe the rule data or init rule error!check the error log!:
java.lang.RuntimeException: subscribe the rule data or init rule error!check the error log!

这应该就是SQL parser、数据操作、结果排序和聚合等核心业务的层吧。后面的几项hibernate shards也差不多都实现了。就是对SQL Parser有些好奇你们是怎么做的。
我也维护着一个javacc的SQL分析器，开始性能还不错，但当支持的SQL语法越来越多以后（众多的DDL、Oracle分析函数、OracleHint……）之后。我发现性能变得非常糟糕。一个简单的SQL几乎要300us。我也剥离了Druid中的SQL Parser进行测试，性能差不多是我写的三倍，但是Druid的分析器维护起来似乎工作量大了一点（我的目的是要支持MSSQL、PG、SQLIte、DERBY、Maria、HSQLDB、神通、GBase），我的天……。所以还想看看你们是怎么做的。

不继续推进了？

我在用Intellij IDEA打开源码的时候，发现注释基本上都是乱码的，感觉不是太友好。

都两年多了，分库分表层还不开源吗？

如上，其实是Version代码在检测jar版本的时候出错了。
比如在spring-boot中检测的代码位置为：

file:/Users/xingoo/IdeaProjects/test-recommend/target/recommend.jar!/BOOT-INF/lib/guava-20.0.jar!/com/google/common/collect/MapMaker.class
version：recommend

因此需要修改检测jar版本的代码:

public static String getVerionByPath(String file) {
        if (file != null && file.length() > 0 && StringUtils.contains(file, ".jar")) {
            int index = StringUtils.indexOf(file, ".jar");
            file = file.substring(0, index);
            int i = file.lastIndexOf('/');
            if (i >= 0) {
                file = file.substring(i + 1);
            }
            i = file.indexOf("-");
            if (i >= 0) {
                file = file.substring(i + 1);
            }
            while (file.length() > 0 && !Character.isDigit(file.charAt(0))) {
                i = file.indexOf("-");
                if (i >= 0) {
                    file = file.substring(i + 1);
                } else {
                    break;
                }
            }
            return file;
        } else {
            return null;
        }
    }

修改为:

int index = StringUtils.lastIndexOf(file, ".jar");

分库分表开源出来不
