空指针异常,这类错误非常的常见,没有源代码分析不了呀,给你一些提示吧
如果是我的话就这么解决：
在上面这句话处打断点,debug,看cityBao是否有值,如果有的话再看this.cityBao.getCityDao()是否为空.
不知道你是否采用spring框架,要是用了的话检查一下dao是否已经注入进来.
建议：要是做程序员的话,调试是一定要学会的,这是一个程序员基本的要求,自己找一找一定能调试出来的.-------学会debug!

空指针异常,导致后面没法调用到方法
this.cityBao 可能为空
this.cityBao.getCityDao() 也可能为空;
用断点或输出一下看看哪个为空就知道了

打断点,自己调试
