如何配置 IntelliJ 的 Java 代码样式以便在长时间优先于链式方法调用时包装分配的右手

Question

I've been having an issue to configure IntelliJ's Java code style to my liking. When I type some operation with streams I have something like this:

    VeryVeryVeryLongNamedClazz instance = container.getList()
                                                   .stream()
                                                   .filter(element -> element.getRole()
                                                                             .equals("CFG"))
                                                   .findFirst()
                                                   .get();

When class names and variable names are quite long, and if the code is quite nested, the whole code block gets shifted far too right to the right for my liking.

Something like this would be much more to my liking:

    VeryVeryVeryLongNamedClazz instance = 
            container.getList()
                     .stream()
                     .filter(element -> element.getRole()
                                               .equals("CFG"))
                     .findFirst()
                     .get();

Is there a way to configure the Java code style so that right hand of the assignment gets wrapped to the next line when the line is too long, or that the assignment rule takes priority over method call rule?

EDIT: To be more clear, what I'm looking for is that on wrapping, the assignment rule is done before chained method rule.

With 'Hard Wrap' at 60 and your code sample, I was able to achieve the desired result on hitting Ctrl+Alt+L using the following settings under File | Settings | Editor | Code Style | Java > Wrapping and Braces :

I would prefer that chained method calls are wrapped always only for streams, and that other methods are allowed to exist in the same line until end of line is reached

Don't think it's possible with current settings. But you can always submit a new feature request to the IntelliJ IDEA developers on YouTrack.
