ServiceLocatorFactoryBean获取Bean方法

对于不同输入需要调用不同实现类,可以考虑使用ServiceLocatorFactoryBean

定义一个interface代理接口（根据类型来判断选择哪一个实现）

public interface BeanFactory {
    //type 是具体Bean类型
    TestBeanFactory get(String type);
}

定义ServiceLocatorFactoryBean定位配置类

@Configuration
public class TestFactoryConfig {
    @Bean("Test")
    public ServiceLocatorFactoryBean dataWarehouseFactory() {
        ServiceLocatorFactoryBean dataWarehouseFactory = new ServiceLocatorFactoryBean();
        dataWarehouseFactory.setServiceLocatorInterface(BeanFactory.class);
        return dataWarehouseFactory;
    }

定义定义一个interface接口

public interface TestBeanFactory {
    String geName();
}

编写TestFactoryService的实现类，根据方法getBean获取具体的Bean方法

@Service("A")
public class TestBeanFactoryImplA implements TestBeanFactory {
    @Override
    public String getName() {
        return "调用A成功";
    }
}

@Service("B")
public class TestBeanFactoryImplB implements TestBeanFactory {
    @Override
    public String getName() {
        return "调用B成功";
    }
}

测试1：

@Resource
private BeanFactory beanFactory;	

@Test
    public void DemoTest() {
        TestBeanFactory testBeanFactory = beanFactory.get("B");
        System.out.println("输出结果："+testBeanFactory.getName());
    }

输出：输出结果：调用B成功

测试2：

@Resource
private BeanFactory beanFactory;	

@Test
    public void DemoTest() {
        TestBeanFactory testBeanFactory = beanFactory.get("A");
        System.out.println("输出结果："+testBeanFactory.getName());
    }

输出：输出结果：调用A成功
