带注释的Spring MVC 3验证 - 不显示形式:错误

Question

我已经坚持了大约一个小时,这不是我第一次这样做,但我无法弄明白.

它应该显示表单错误,而不是它抛出此异常.

LE:我在此期间设法解决了异常,但我仍然无法看到错误.他们没有呈现

Answer 1

似乎必须依赖于映射控制器方法中必须列出参数的顺序.
例如:

public String addCategory(@Valid CategoryAdd category,BindingResult result, 
Map map)

会工作,而:

public String addCategory(@Valid CategoryAdd category, Map map, 
BindingResult result)

将不会.我不完全理解为什么会这样,特别是因为它编译没有任何问题.
