带有@NotEmpty批注的Spring MVC表单变量，一个具有多个表单的POJO

Question

I am working on spring mvc with annotations.

I have a POJO with three fields userName, password and mailId which are annotated as @NotEmpty . I have two forms :

1. Loginform.jsp : contains two input fields userName and password.
2. Forgotpassword.jsp : contains only one input field mailId.

The problem is if I use the same pojo for both jsp forms it's giving me binding result errors, as for login.jsp I don't need mailId, and for forgotpassword.jsp I don't need userName and password, but all these fields are annotated as @NotEmpty in my POJO,so gives validation error.

Q: How to deal with the situation? Do I need to create separate POJO for each Form?

Answer 1

According to me, login and forgot-password are two very different business usecases, and as such deserve separate POJOs. Doing so would also, in future, guard you against accidently exposing the password in forgot-password page.
