mixing constructor autowiring with setters.

[cablepuff]

HI i want to achieve this, what is the best way to do it.


i have

class Library {
    private BookService bookService; 

    private Integer maxCheckout;

    @Autowired
    Library(@Qualifier("cablepuff.bookService") BookService bookService) {
         super():
         this.bookService = bookService;
    }

    public void setMaxCheckout(Integer maxCheckout) {
        this.maxCheckout = maxCheckout;
    }
}

What is the best way to acheive this. I want BookService to be autowired via constructor and maxCheckout to be set by xml definition.

By simply doing as you state... Define the bean in xml, dependency, tell the context to use annotations and presto...

Thanks it works.

*** edit **** never mind i get this error.

        <bean class="org.springframework.beans.factory.annotation.QualifierAnnotationAutowireCandidateResolver"/>
	<bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"/>
	<bean class="org.springframework.beans.factory.annotation.RequiredAnnotationBeanPostProcessor"/>

i have this defined in my xml, when i start up app i get this error.
