執(zhí)行update批量更新時報錯

在使用Mybatis 批量更新時

想要批量更新時通常在mapper中這么寫：

定義Mapper Dao接口中定義

最后在service中調用

生成的sql直接放到mysql中運行完全沒有問題，但是mybatis執(zhí)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(shù)據(jù)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“&”

同時執(zhí)行多條sql的辦法

1、最簡單的辦法：在MySQL的連接字符串中設置allowMultiQueries參數(shù)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(zhí)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。

執(zhí)行update失敗問題

今天在進行分布式重構項目的時候碰到一個問題，在執(zhí)行sql的時候只有update不能成功，其他語句都可以正常執(zhí)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

說下原因

由于mybatis在執(zhí)行insert和update的時候都默認生成key，然后注入，所以在執(zhí)行update的時候會報錯。

解決辦法

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。

以上為個人經(jīng)驗，希望能給大家一個參考，也希望大家多多支持腳本之家。
