Mybatis 模糊查詢 動態sql 插入回填

方式一：用「%$%」

"selectuser"

parametertype
="com.gec.bean.user"
resulttype
="com.gec.bean.user"
>
select * from t_user where address like "%$%"
select
>

"selectuser"

parametertype
="com.gec.bean.user"
resulttype
="com.gec.bean.user"
>
select * from t_user where address like #
select
>

@test

public
void
testselectuser()
session.
close()
;}

1、用if標籤，新增where子句後的條件

"dynamicselect"

parametertype
="com.gec.bean.user"
resulttype
="com.gec.bean.user"
>
select * from t_user where 1=1
test
="username!=null"
>
and username=#
if>
test
="address!=null"
>
and address like #
if>
select
>

"dynamicselect2"

parametertype
="com.gec.bean.user"
resulttype
="com.gec.bean.user"
>
select * from t_user
>
test
="username!=null"
>
and username=#
if>
test
="address!=null"
>
and address like #
if>
where
>
select
>

"dynamicselect3"

parametertype
="com.gec.bean.user"
resulttype
="com.gec.bean.user"
>
select * from t_user
>
>
test
="username!=null"
>
and username=#
when
>
test
="address!=null"
>
and address like #
when
>
choose
>
where
>
select
>

主鍵在資料庫中是自增長，插入資料時，不管插入的id有沒有值都會被自增長的主鍵覆蓋。插入完成後，可以通過「插入回填」，把自增長的id回填得到pojo物件中

"insert"

parametertype
="com.gec.bean.user"
>
insert into t_user(id,address,username,birthday) values(#,#,#,#)
keyproperty
="id"
keycolumn
="id"
resulttype
="int"
order
="after"
>
select last_insert_id()
selectkey
>
insert
>

@test

public
void
testinsert()
catch
(ioexception e)
}
