How to prevent Spring validation on update

问题

I made a custom validation annotation for unique email (When user registers itself, program checks if email is already in database).

Everything works just fine, but when I need to modify user's info and not to create a new one I run into a problem that says "Email is already in use"

Can I somehow turn off only @UniqueEmail validation(I need the others like email pattern and password validation)?

All validation annotations are in the same User bean.

Thank You.

I'm going to assume that you are using javax.validation.

First you need an interface OnUpdate:

javax.validation.groups.Default

public interface OnUpdate extends Default {}

Now you need to set all the annotations that need to only run on UPDATE:

@NotNull(groups = OnUpdate.class)

Now, you have divided your validations into two groups, those in OnUpdate and those in Default. Running Default will include those in OnUpdate as OnUpdate extends Default.

Now, this is where it gets a little tricky - you need to tell the framework which validations to run on each task.

If using JPA you just need to set the following property:

javax.persistence.validation.group.pre-update = com.my.package.OnUpdate

Further to Boris The Spider's answer, if you want to do this in code rather than with persistence.xml you can create the following bean:

  @Bean
  public HibernatePropertiesCustomizer hibernatePropertiesCustomizer(final Validator validator) {
    return new HibernatePropertiesCustomizer() {

      @Override
      public void customize(Map<String, Object> hibernateProperties) {
        @SuppressWarnings("rawtypes")
        Class[] classes = {OnUpdate.class};
        hibernateProperties.put("javax.persistence.validation.group.pre-update", classes);
      }
    };
  }
