GvNix的最佳功能之一是“典型安全性”。
此功能很有用,但在使用“web mvc批量设置”功能时会中断。
作为测试用例,我使用了https://github.com/DISID/gvnix-samples/blob/master/quickstart-app/quickstart.roo
中的Quickstart.roo脚本我在剧本中唯一改变的是用“典型安全设置”取代“安全设置”。 我测试了它,最后发现只要我不使用“web mvc批量设置”功能一切正常。
据我所知,发出此命令会导致2次更改: 1)POM.XML和2)WEB-INF / spring / webmvc-configxml
最后是添加了以下代码:
<bean class="org.gvnix.web.json.Jackson2RequestMappingHandlerAdapter" id="dataBinderRequestMappingHandlerAdapter" p:order="1">
<property name="objectMapper">
<bean class="org.gvnix.web.json.ConversionServiceObjectMapper"/>
</property>
</bean>
使用mvn tomcat运行webapp时会生成以下错误:运行

答案 0 :(得分:0)
它看到你是对的,这个附加组件创建了bean,它实现了Validator
,以验证创建的新表单。因此,Spring无法注入默认验证器,因为它无法识别哪个是正确的。
拜托,你能在gvNIX githut repo上创建一个任务吗?
可能的解决方法可能是删除implement
类Validator
的{{1}}和ChangePasswordValidator
。尝试一下,让我们知道它是否有效。
