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。以上为个⼈经验，希望能给⼤家⼀个参考，也希望⼤家多多⽀持。
