MyBatis 中单个映射器方法中的多个语句

我有一个映射器方法来删除表中的所有记录。但首先我需要删除关联连接表中的所有记录。这是我尝试过的：

@Delete("delete from COC_BLOCK_FIELD; delete from COC_BLOCK;")
void deleteBlocks();

这看起来很合理，但 MyBatis 在处理我的映射器时抛出异常：

Caused by: org.apache.ibatis.exceptions.PersistenceException: 
### Error updating database.  Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'delete from COC_BLOCK' at line 1
### The error may involve defaultParameterMap
### The error occurred while setting parameters
### SQL: delete from COC_BLOCK_FIELD; delete from COC_BLOCK;
### Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'delete from COC_BLOCK' at line 1

我正在使用 MyBatis 3.2.6、MySQL 5.5.35-1ubuntu1 和 MySQL Connector 5.1.26。

问题是我没有设置标志allowMultiQueries=true在 JDBC URL 中。
