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。
