创建存储过程
CREATE DEFINER=`root`@`localhost` PROCEDURE `select_user_count`(out userCount INTEGER,OUT postCount INTEGER)
BEGIN
#Routine body goes here...
SELECT count(*) as userCount from tb_sys_user into userCount;
SELECT count(*) as postCount from tb_posts_post into postCount;
END
创建对象
public class CountVo implements Serializable {
private static final long serialVersionUID = 1481563278090175522L;
private Integer userCount;
private Integer postCount;
//toString,get,set........
}
注解使用(不可设置数据为只读,不然out会报错的)
@Select({"call select_user_count(#{userCount,mode=OUT,jdbcType=INTEGER},#{postCount,mode=OUT,jdbcType=INTEGER})"})
@Options(statementType = StatementType.CALLABLE)
void getCount(CountVo countVo);
xml调用
<select id="getCount" parameterType="com.base.CountVo" statementType="CALLABLE">
{call select_user_count(
#{userCount,mode=OUT,jdbcType=INTEGER},
#{postCount,mode=OUT,jdbcType=INTEGER})}
</select>
service层调用
CountVo countVo = new CountVo();
tbSysUserMapper.getCount(countVo);
System.out.println(countVo.toString());
