我采用了Springmvc Validator进行表单验证,部分代码如下:

Contriller类:

VaildAccount类:

Account类

 

错误信息:

我提交的是一个空表单,即表单没有填写任务内容,出现如下错误信息:

望大神指出哪里出错了

严重: Servlet.service() for servlet [myjpetstore] in context with path [/myjpetstores] threw exception [Request processing failed; nested exception is java.lang.IllegalStateException: Invalid target for Validator [org.springframework.samples.myjpetstores.io.VaildAccount@6e5ab186]: org.springframework.validation.BeanPropertyBindingResult: 1 errors
