oracle和mysql数据库的批量update在mybatis中配置不太一样：
oracle数据库：
|
1
2
3
4
5
6
7
8
9
10
11
|
<
update
id=
"batchUpdate"
parameterType=
"java.util.List"
>
<foreach collection=
"list"
item=
"item"
index
=
"index"
open
=
"begin"
close
=
"end;"
separator=
";"
>
update
test
<
set
>
test=${item.test}+1
</
set
>
where
id = ${item.id}
</foreach>
</
update
>
|
mysql数据库：
mysql数据库采用一下写法即可执行，但是数据库连接必须配置：&allowMultiQueries=true
例如：jdbc:mysql://192.168.1.236:3306/test?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=true
