立马就蒙了，刚才调试还正常呢，就增加了update就出现这个问题，下面是我update的语句

 <update id="updateOrder" parameterType="com.heibai.bookspringboot.pojo.Order ">
        update t_order
        <set>
            <if test="orderId!=null">orderId=#{orderId}</if>
            <if test="createTime!=null">createTime=#{createTime}</if>
            <if test="price!=null">price=#{price}</if>
            <if test="status!=null">status=#{status}</if>
            <if test="userId!=null">userId=#{userId}</if>
            <if test="payStatus!=null">payStatus=#{payStatus}</if>
        </set>
        where orderId=#{orderId}
    </update>

经过查看mybatis官方文档 感觉也是没有错（事实证明有时候感觉是不对的啊），所以一度怀疑是不是其他代码出了问题，可是在我将这段代码注释掉后，发现程序可以正常跑起来，那么就一定是这段代码的问题。
之后我又对自己的代码一行一行的读，发现parameterType="com.heibai.bookspringboot.pojo.Order ">这句的最后多了一个空格，但是我也不知道是不是这个原因。之后把空格去掉，程序跑起来了！但是又出现了另外的错误，唉，码农的路上注定荆棘丛生啊。

org.springframework.jdbc.BadSqlGrammarException:

后来又是经过一系列找原因，终于发现少了 几个“，”号

<set>
            <if test="orderId!=null">orderId=#{orderId}</if>
            <if test="createTime!=null">createTime=#{createTime}</if>
            <if test="price!=null">price=#{price}</if>
            <if test="status!=null">status=#{status}</if>
            <if test="userId!=null">userId=#{userId}</if>
            <if test="payStatus!=null">payStatus=#{payStatus}</if>
        </set>

加上“，”号，程序终于成功了

我激动的心，颤抖的手啊，这时候就想来碗酒啊！！！

所以一定要细心！一定要细心！一定要细心啊！重要的话说三遍！
