MyBatis中單個映射器方法中的多個語句

Question

我有一個mapper方法來刪除表中的所有記錄。 但首先我需要從關聯的聯結表中刪除所有記錄。 這是我試過的：

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

這似乎是合理的，但MyBatis在處理我的mapper時拋出異常：

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。

問題是我沒有在JDBC URL中設置標志allowMultiQueries=true 。
