SqlSource.builder().build()

`SqlSource.builder().build()` 是 CSDN 上 C 知道开发的一个方法调用。它是用于构建 SQL 查询的 SqlSource 对象。在这个方法调用中，使用了建造者模式来构建 SqlSource 对象，然后调用 `build()` 方法来返回构建好的对象。具体的实现细节可以参考 CSDN 文档或者源代码。

这个错误出现在使用 MyBatis 框架时，可能是因为配置文件中的数据源属性 maxPoolPreparedStatementPerConnectionSize 被认为是未知的。可以检查配置文件中的数据源属性是否正确，或者尝试将其删除并测试是否能够解决问题。如果问题仍然存在，可能需要检查 MyBatis 和数据库驱动程序的版本是否兼容。

这个错误是由于在解析 SQL Mapper 配置时出现问题导致的。根据错误信息，可能是由于未知的数据源属性 'serverTimezone' 导致的。

解决这个问题的方法是确保你的数据源配置正确，并且没有使用未知的属性。根据错误信息，你可以尝试以下解决方法：

1. 检查你的数据源配置文件（比如 `mybatis-config.xml`）中是否使用了正确的数据源类型和属性。

2. 如果你使用的是 MySQL 数据库，可以尝试添加 `serverTimezone` 属性到数据源配置中。例如：

   <dataSource type="com.mysql.cj.jdbc.MysqlDataSource">
     <property name="url" value="jdbc:mysql://localhost:3306/database_name?serverTimezone=Asia/Shanghai"/>
     <property name="username" value="your_username"/>
     <property name="password" value="your_password"/>
   </dataSource>

将 "database_name" 替换为你的数据库名，"your_username" 和 "your_password" 分别替换为数据库的用户名和密码。

3. 检查你的 MyBatis 版本是否与你使用的数据库驱动程序和数据库服务器兼容。确保使用的 MyBatis 版本与你的数据库版本匹配，并且数据库驱动程序与 MyBatis 版本兼容。

如果问题仍然存在，请提供更多关于你的配置文件和代码中的相关代码，以便我能够更好地帮助你解决问题。
