在使用Mybatis的时候,常常会有各类各样的参数传递,不一样类型,不一样个数的参数。.net
先上个例子:
public List<LifetouchRelease> findOfficeList(@Param("lifetouchRelease") LifetouchRelease lifetouchRelease,
@Param("advertisementId") String advertisementId, @Param("officeName") String officeName,
对象
@Param("isOnline") Integer isOnline);
<select id="findOfficeList" resultType="LifetouchRelease">
SELECT
<include refid="lifetouchReleaseColumns"/>
FROM lifetouch_release a
<include refid="lifetouchReleaseJoins"/>
<where>
<if test="lifetouchRelease.typeIdentification > 0">
AND a.type_identification = #{lifetouchRelease.typeIdentification}
</if>
<if test="lifetouchRelease.category != null andlifetouchRelease.category.id != null andlifetouchRelease.category.id != ''">
AND a.release_type_id = #{lifetouchRelease.category.id}
</if>
AND a.office_id is not null
AND a.advertisement_id like '%${advertisementId}%'
AND (select name from sys_office where id=a.office_id) like '%${officeName}%'
<if test="isOnline != null">
AND a.del_flag = #{isOnline}
</if>
</where>
<choose>
<when test="lifetouchRelease.page !=null andlifetouchRelease.page.orderBy != null andlifetouchRelease.page.orderBy != ''">
ORDER BY ${lifetouchRelease.page.orderBy}
</when>
<otherwise>
ORDER BY a.update_date DESC
</otherwise>
</choose>
</select>

上面是一个包含:实体对象,普通类型,多个参数的传递。get
多个参数:使用注解的方式实现io
实体对象:实体对象跟普通类型参数传递方法同样,只是在用的时候,以 对象名.(点)对象属性名 的方式调用就能够了。
test
其它传递,不过数据类型多复杂也是如此。date
