java Querydsl错误结果与or（）

Question

I'm new to querydsl and probably I miss the concept somehow. What I want to do is fetch all person objects, who's name starts with "He", or who's birthday has passed or who's adresses' street starts with "ge".

When I use the snippet here, I only get the person objects who match the third condition (person.adresse.strasse). The first zwo conditions are completely ignored. If I comment out the third condition, I get the results where the two first conditions (person.name machtes or person.birthday.before) matches.

What am I doing wrong? Do I have to do a join instead?

List<Person> persons = query.select( person )
            .from( person )
            .where(
                    person.name.startsWith( "He" )
                    .or( person.birthday.before( new Date( System.currentTimeMillis() ) )
                            .or( person.adresse.strasse.startsWithIgnoreCase( "ge" ) ) )
            )
            .fetch();

Answer 1

You have wrong number of parenthesis.

Unintentionally, you have nested the third or inside the second one, that's why when you comment the third or you get correct results.

Try this:

List<Person> persons = query.select( person )
            .from( person )
            .where(
                    person.name.startsWith("He")
                    .or(person.birthday.before(new Date(System.currentTimeMillis())))
                    .or(person.adresse.strasse.startsWithIgnoreCase("ge")) 
            )
            .fetch();

It should work.
