系统起来,页面访问报空指针错.折腾了好几个小时.

原因是因为修改了model中的校验器,然后dorado控件存在bug导致参数丢失. type="range"丢掉了

导致启动ok 访问页面就报空指针错误.

解决思路:

先判断是eclipse的问题,还是代码的问题.

将程序部署到测试环境也报相同的错误,确定为程序的问题.

猜测是某个文件的修改导致,看了下svn的提交日志.各个文件逐一排查.

将soliTool.model.xml 退回到老版本,并且将删掉的java类加回来,页面能正常访问.

定位到这个文件的原因.

<Property name="dataType">Integer</Property>

<Property name="maxValueValidateMode">allowEquals</Property>

<Property name="minValueValidateMode">allowEquals</Property>

<Property name="resultMessage">小时区间为9~23</Property>

</Validator>

</PropertyDef>
