解决办法：根据这个现象在网上查了很多，大部分都是说oracle驱动不支持，更换驱动之类的，限于我拥有的驱动资源，不能这么解决，

还查到有人说是：

1、主键没有自增

2、表中字段数据类型与bean中的数据类型不一致，请将数据类型与表中类型一致就可，

这是我突然想到oracle的主键自增与mysql 的主键自增机制不同，故而就是我的mybatis的xml映射语句有问题，于是更改如下：

<!-- 添加 -->
<insert id="add" parameterType="Standard" useGeneratedKeys="true">
<selectKey keyProperty="id" resultType="int" order="BEFORE">
select SEQUENCE_STANDARD.nextval as id from dual
</selectKey>
insert into standard(id,zhname,version,keys,release_date,impl_date,ackage_path)
values(#{id},#{zhname},#{version},#{keys},#{release_date},#{impl_date},#{ackage_path})
</insert>

此时运行，又发现如下报错：

org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.type.TypeException: Could not set parameters for mapping: ParameterMapping{property='keys', mode=IN, javaType=class java.lang.String, jdbcType=null, numericScale=null, resultMapId='null', jdbcTypeName='null', expression='null'}.
