问题 I've never seen an autowired collection: @Service public class SomeFactory { @Autowired private List<Foo> foos; @PostConstruct public void init() { for(Foo foo: foos) { //do something } } } In init() method, I can see foos has several entries already. I guess Spring knows who's supposed to be the entry of foos. But, how? What should I do if I want to add a Foo object into foos? Need to configure in a property file, or any other idea? 回答1: Spring's BeanFactory is basically a registry of beans.

问题 I normally just @Autowire things into spring objects. But I've encountered a situation where I need to dynamically create some objects which require values that could be autowired. What should I do? What I could do is just manually pass the autowired values into the constructor of the new objects. What I would like to do is just autowire each new object as I create it. @Service public class Foo { @Autowired private Bar bar; /** This creates Blah objects and passes in the autowired value. */

I get this error: java.lang.IllegalStateException: Cannot convert value of type

问题 I have two classes: vehicle.Tire and vehicle.Car. package vehicle; @Named public class Tire { private String age; } package vehicle; @Named public class Car { private Tire tire; // Spring calls this setter because default-autowire="byName" of xml configuration public void setTire(Tire newTire) { this.tire = newTire; } public Tire getTire() { return this.tire; } } The following spring xml works fine. <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001
