java - 如何使用 XML 配置文件配置 Spring 4 中提供的条件 bean

Question

我想使用 XMl Spring 配置而不是通过注释来配置下面示例中所示的条件 bean。是否可以通过XML配置来实现条件bean？

public class TestCondition1 implements Condition
{
  @Override
  public boolean matches(ConditionContext conditionContext, AnnotatedTypeMetadata annotatedTypeMetadata)
  {
    return context.getEnvironment().getProperty("os.name").contains("Windows");
  }
}

@Configuration
public class BeanTestConfiguration
{
  @Bean(name="TesService")
  @Conditional(TestCondition1.class)
  public BeanTestConditionService getTestService()
  {
    return new BeanTestConditionService();
  }
}

public class BeanTestConditionService
{
  public BeanTestConditionService()
  {
    System.out.println("I am in test setvice");
  }
}

Not supported yet ，并且可能暂时不会

Eventually closing this as Won't Fix since the whole condition model has really been designed with annotations in mind, and is generally a better fit there. If any common needs remain for XML configuration, we'd rather fine-tune the declarative profile model which is already available in XML.
