像sqlmap存在转换问题。类似selectOne 未知,是否未对应上。把查询的sqlmap贴出来下。

mybatis和springmvc 中sql语句遇到的奇怪问题
框架是springmvc+mybatis.mybatis版本是3.2.8 数据库是sqlserver2008r2 某个模块 xml中添加和修改没有问题, 查询语句遇到问题了。所有的select 返回对象或者list的时候报错。 ``` <select id="findClazz" resultType="clazz" parameterType="clazz"> select * from tc_department </select> ``` ### Error querying database. Cause: java.lang.NumberFormatException: For input string: "" ### The error may involve dingzhen.dao.ClazzDao.findClazz-Inline ### The error occurred while setting parameters ### Cause: java.lang.NumberFormatException: For input string: "" 这个是错误代码,把查询参数去掉。也抱着个错。 # **但是** ``` <select id="findClazz" resultType="int" parameterType="clazz"> select count(*) from tc_department </select> ``` 却正常运行。 列与clazz类对应正确。其他模块相同写法正常使用。

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它
程序员必须掌握的核心算法有哪些?

程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发
