BeanFactory lacks method for getting bean by type with specified constructor arguments [SPR-11235]

[spring-projects-issues]

Pavel Petrov opened SPR-11235 and commented

In BeanFactory interface we have only one option to create a prototype bean which has a constructor with arguments: Object getBean(String name, Object... args), which requires a type cast (it returns Object) and requires providing explicit name for a bean (even if there's a single implementation).

Could you please consider adding getBean(Class requiredType, Object... args) as well?
