mybatis报错 Cause: java.sql.SQLException: 序列号无效

一、问题描述

 引入mybatis之后 在进行更新语句时候出现异常！！！

二、DEBUG问题位置并解决

走下面日志发现，错误在更新语句时候出现了sql语法错误org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.type.TypeException: Could not set parameters for mapping: ParameterMapping{property=‘form_type’, mode=IN, javaType=class java.lang.String, jdbcType=null, numericScale=null, resultMapId=‘null’, jdbcTypeName=‘null’, expression=‘null’}. Cause: org.apache.ibatis.type.TypeException: Error setting null for parameter #12 with JdbcType OTHER . Try setting a different JdbcType for this parameter or a different jdbcTypeForNull configuration property. Cause: dm.jdbc.driver.DMException: 序列号无效

其中关键文字：Could not set parameters for mapping 后面跟着了form_type字段名称，查看sql语句如下：

    <update id="***" parameterType="***">
        update **
        set returnWay=#{returnWay},
            ...此处省略
--             ,form_type=#{formType},
        where id = #{id}
    </update>

这里发现我们的sql中存在一行注释
-- ,form_type=#{formType}标识的代码，查阅mybatis官方文档说是会被预编译
因为包含了#
如果把-- ,form_type=#{formType}改成-- ,form_type={formType}也就是去掉#
就不会报错！！！

总结：在mybatis中,使用注释代码,不能包含mybatis标签的语法#{}或者${}都不可以
否则会预编译
