本文详细介绍了在使用Struts2+Hibernate+Spring进行开发时，遇到的一个关于Bean属性设置的错误，并分析了错误原因及解决办法。特别强调了在整合开发时注意单词大小写的规范性，避免因小错误导致的大问题。

今天让我郁闷的一个问题,再开发一个***系统的时候,我采用的是struts2+Hibernate3+spring2.5进行开发的，但是就莫名奇妙的出现了一个错误:bug的信息如下：

 

org.springframework.beans.NotWritablePropertyException:
Invalid property 'tStruct' of bean class [com.ac.equipment.dm.Bus]:
Bean property 'tStruct' is not writable or has an invalid setter method.
Did you mean 'tstruct'?

..........................................


其实我的错误原因是在我的Bean中有一个 private String tStruct的属性,我在对应的setter和getter方法中,我是这样写:

    public void setTStruct(String tStruct){------------}
    public String getTStruct(){-------------}

其实当自动生成代码的时候并不是这样 ，而是settStruct() gettStruct();所以一定要注意第一个单词的大小写的问题 。

 

 

还有在使用hibernate+spring整合开发的时候，一定要注意注入的单词大小写的规范，这一点也在我其他的blog中有说明，希望对你有所帮助！
