/>      项目中同时采用了Hibernate3和Hibernate2（JDK1.5），并采用Oracle最新的jdbc thin驱动（10g），针对clob操作，hbm映射都采用了text，实际操作中发现Hibernate3操作正常，而Hibernate2老报ORA-01461错误，尤其是在中英文、符号混和文本中更是如此！<br />      实际测试后发现当数据字符数量在2000～4000之间出现错误！而数据量一旦超出4000之后又恢复正常了！<br />      网上也发现有类似的案例，不知道算不算Oracle驱动的一个bug？目前的解决办法是在对字段操作时，统一填入4000个空格，在应用中使用再把空格过滤掉，解决的比较别扭，但暂时还没有找到更好的办法！<br />      另外，在测试中发现，Oracle的驱动尽量使用新版本的，稳定性和兼容性都比较好<br /><img src ="http://blog.csdn.net/LongLongRiver/aggbug/4268846.aspx" width = "1" height = "1" /><img

在使用了AppFuse之后，我有个想法，能不能利用velocity这个优秀的模板引擎，用一种更加直观的模式，把开发项目中的重复代码让它自动生成，生成之后的基础代码，按照实际的需求稍作修改便可以运行，极大的提高工作效率。这样的话，程序员就可以从大量的重复劳动中解放出来，将精力更多的投入到业务分析及学习中。<img src
