想要批量更新時通常在mapper中這么寫:
生成的sql直接放到mysql中運行完全沒有問題,但是mybatis執行的時候卻會報錯:

這是因為配置mysql的時候沒有開啟批量插入,不開啟的話只能允許操作一條sql語句,所以只需要修改一處即可:將properties配置文件中的數據庫連接信息URL后面添加上&allowMultiQueries=true就可以了,問題完美解決。
如圖:
注意:請不要將“&”符號寫成“&”
1、最簡單的辦法:在MySQL的連接字符串中設置allowMultiQueries參數置為true。(只有MySQL Connector/J 3.1.1以上版本才支持) 。例如:在jdbc下設置連接字符串的時候設成如下的形式:
jdbc:mysql://172.17.42.197:3306/yihg_openapi?useUnicode=true&characterEncoding=utf8&allowMultiQueries=true就可以執行多條語句了
在odbc下也是可以設置的,方法如下:
設置 ODBC — 配置 –Detials — Flags 3 — 鉤上 Allow multiple statements,這樣就可以了。
結論:第一種方式最簡單。
2、在程序中對SQL語句以分號拆分成多條SQL語句,然后使用Statement的addBatch方法,最后executeBatch就行。
今天在進行分布式重構項目的時候碰到一個問題,在執行sql的時候只有update不能成功,其他語句都可以正常執行,報錯如下: 版本:org.mybatis:mybatis:3.4.5
接口:
@UpdateProvider(type = ManagerProvider.class, method = "updateManager") int updateManager(Manager manager) throws Exception;
報錯信息
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: 不允許的操作;uncategorized SQLException for SQL []; SQL state [99999]; error code [17090]; 不允許的操作; nested exception is java.sql.SQLException: 不允許的操作
由于mybatis在執行insert和update的時候都默認生成key,然后注入,所以在執行update的時候會報錯。
在接口上增加注解 @Options(useGeneratedKeys = false),不讓mybatis自動注入key,問題解決。
@UpdateProvider(type = ManagerProvider.class, method = "updateManager") @Options() // @Options(useGeneratedKeys = false) int updateManager(Manager manager) throws Exception;
最后說明一點,版本:org.mybatis:mybatis:3.4.4這個版本沒有此類問題。
