mybatis中selectKey生成uuid(oracle、mysql)

1.mybatis+mysql自动生成uuid主键

​
<insert id="insert" parameterType="com.jo.model.Functions" >
  
    <selectKey keyProperty="pkGlobalId" resultType="String" order="BEFORE">
        select  replace(uuid(),'-','')   from dual
    </selectKey>
     
    insert into tbl_function (pk_global_id, name, parent_id, 
      sort, url)
    values (#{pkGlobalId,jdbcType=VARCHAR}, #{name,jdbcType=VARCHAR}, #{parentId,jdbcType=VARCHAR}, 
      #{sort,jdbcType=INTEGER}, #{url,jdbcType=VARCHAR})
  </insert>

​

在数据库中运行SQL

2.mybatis+oracle 生成uuid

 <selectKey resultType="java.lang.String" keyProperty="comId" order="BEFORE">
            select sys_guid() from dual
        </selectKey>

在不同的项目中我是使用这两种方法生成的uuid,如有不足,欢迎指正!
