在更新数据时候出现的错误
更新代码如下：
<update id="modify" parameterType="Standard">
update standard
<set>
<if test="zhname!=null">zhname=#{zhname},</if>
<if test="version!=null">version=#{version},</if>
<if test="keys!=null">keys=#{keys},</if>
<if test="release_date!=null">release_date=#{release_date},</if>
<if test="impl_date!=null">impl_date=#{impl_date},</if>
<if test="ackage_path!=null">ackage_path=#{ackage_path }</if>
</set>
where id=#{id}
</update>
仔细查看，起始这段代码没问题，那问题出现在哪里呢？网上各种搜都是说添加null的问题，我这个问题呢，最终发现是因为在我的查看页面点击进入修改页面以后，修改数据提交时，没有提交id，把id弄丢了，控制台打印id时候显示id=null,于是报错如下，查找半天，没找到，长点记性，细心，从逻辑层面认真思考吧。
然后在修改的jsp页面上把id的隐藏框加上后，就ok了。
