如何使用通过 QueryDSL 返回布尔值的方法？

Question

I have an object message and an authenticated user . I want to only show a message to the authenticated user, if they are the author or have a specific role.

private boolean isEditor(User user){
    // some complex logic
}

QMessage message = QMessage.message;
User user = getAuthenticatedUser();
boolean isEditor = isEditor(user);
BooleanExpression canRead = message.author.id.eq(user.getId()).or(isEditor); // isEditor is not working here

I can't combine the boolean isEditor with the BooleanExpression though, is that possible somehow?

Answer 1

A boolean can be converted to a BooleanExpression like that:

Expressions.asBoolean(isEditor).isTrue();
