CCJSqlParserUtil Caused by: net.sf.jsqlparser.parser.ParseException: Encountered

最近在实现一个功能 就是所有的sql语句都多加上一个查询条件 例如 key='XXXXXXXXX'

实现了mybatis 的拦截器

在拦截器重获取sql语句进行调整，部分代码如下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM4Mzc3MTkw_size_16_color_FFFFFF_t_70][]

其中使用了 CCJSqlParserUtil 这个工具类对进行sql解析，进行添加查询条件

在此过程中我碰到两个问题，并解决。这里分享给大家

问题一：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM4Mzc3MTkw_size_16_color_FFFFFF_t_70 1][]

框框中代码，**statementHandler 对象无法获取 delegate 值**，通过尝试

在拦截配置代码中，我将拦截器顺序提前，得以解决。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM4Mzc3MTkw_size_16_color_FFFFFF_t_70 2][]

问题二：

CCJSqlParserUtil 解析部分复杂sql时 会报错

Caused by: net.sf.jsqlparser.parser.ParseException: Encountered " <S\_CHAR\_LITERAL> "\\'licensePlateDO.licensePlate\\' "" at line 7, column 32.

报错如下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM4Mzc3MTkw_size_16_color_FFFFFF_t_70 3][]

我的sql代码如下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM4Mzc3MTkw_size_16_color_FFFFFF_t_70 4][]

后面通过查阅资料与尝试，是缺少了

com.github.jsqlparser

在当前model下导入该包即可解决。
