mybatis执行update批量更新时报错的解决方案
目录执行update批量更新时报错在使用Mybatis批量更新时定义Mapper Dao接口中定义最后在service中调用同时执行多条sql的办法执行update失败问题说下原因解决办法
执行update批量更新时报错
在使用Mybatis 批量更新时
想要批量更新时通常在mapper中这么写:
定义Mapper Dao接口中定义
最后在service中调用
生成的sql直接放到mysql中运行完全没有问题,但是mybatis执行的时候却会报错:

这是因为配置mysql的时候没有开启批量插入,不开启的话只能允许操作一条sql语句,所以只需要修改一处即可:将properties配置文件中的数据库连接信息URL后面添加上&allowMultiQueries=true就可以了,问题完美解决。
如图:
注意:请不要将“&”符号写成“&”
同时执行多条sql的办法
1、最简单的办法:在MySQL的连接字符串中设置allowMultiQueries参数置为true。(只有MySQL Connector/J 3.1.1以上版本才支持) 。例如:在jdbc下设置连接字符串的时候设成如下的形式:
jdbc:mysql://172.17.42.197:3306/yihg_openapi?useUnicode=true&characterEncoding=utf8&allowMultiQueries=true就可以执行多条语句了
在odbc下也是可以设置的,方法如下:
设置 ODBC — 配置 –Detials — Flags 3 — 钩上 Allow multiple statements,这样就可以了。
结论:第一种方式最简单。
2、在程序中对SQL语句以分号拆分成多条SQL语句,然后使用Statement的addBatch方法,最后executeBatch就行。
执行update失败问题
今天在进行分布式重构项目的时候碰到一个问题,在执行sql的时候只有update不能成功,其他语句都可以正常执行,报错如下: 版本:org.mybatis:mybatis:3.4.5
接口:
@UpdateProvider(type = ManagerProvider.class, method = "updateManager")
int updateManager(Manager manager) throws Exception;
报错信息
Loading XML bean definitions from class path resource [org/springframework/jdbc/support/sql-error-codes.xml]SQLErrorCodes loaded: [DB2, Derby, H2, HSQL, Informix, MS-SQL, MySQL, Oracle, PostgreSQL, Sybase, Hana]org.springframework.jdbc.UncategorizedSQLException: Error getting generated key or setting result to parameter object. Cause: java.sql.SQLException: 不允许的操作;
uncategorized SQLException for SQL []; SQL state [99999]; error code [17090]; 不允许的操作; nested exception is java.sql.SQLException: 不允许的操作
说下原因
由于mybatis在执行insert和update的时候都默认生成key,然后注入,所以在执行update的时候会报错。
解决办法
在接口上增加注解 @Options(useGeneratedKeys = false),不让mybatis自动注入key,问题解决。
@UpdateProvider(type = ManagerProvider.class, method = "updateManager")
@Options() // @Options(useGeneratedKeys = false)
int updateManager(Manager manager) throws Exception;
最后说明一点,版本:org.mybatis:mybatis:3.4.4这个版本没有此类问题。
