Spring配置文件初始化加载（一）

1.枚举

public enum TestEnum {
    type_01("01", "zeroTest01ServiceImpl"),
    type_02("02", "zeroTest02ServiceImpl"),
    type_03("03", "zeroTest03ServiceImpl");
    private String type;
    private String pathClass;
}

2.接口

public interface ZeroTestService {

    /**
     * 校验
     *
     * @param map
     */
    void checkData(Map<String, String> map);

    /**
     * 当前实现对应类型
     *
     * @return
     */
    String getType();
}

3.实现类

@Service
public class ZeroTest02ServiceImpl implements ZeroTestService {
    @Override
    public void checkData(Map<String, String> map) {

    }

    @Override
    public String getType() {
        return null;
    }
}


@Service
public class ZeroTest01ServiceImpl implements ZeroTestService {
    @Override
    public void checkData(Map<String, String> map) {

    }

    @Override
    public String getType() {
        return null;
    }
}

4.实现IOC容器

@Component
public class ZeroTestServiceFactory implements ApplicationContextAware {

    @Autowired
    private ApplicationContext applicationContext;

    public Map<String, ZeroTestService> serviceMap = new HashMap<>();

    public ZeroTestService getZeroTestService(String type) {
        return serviceMap.get(type);
    }

    @Override
    public void setApplicationContext(ApplicationContext context) throws BeansException {
        if (null == context) {
            context = applicationContext;
        }
        for (TestEnum testEnum : TestEnum.values()) {
            serviceMap.put(testEnum.getType(), (ZeroTestService) context.getBean(testEnum.getPathClass()));
        }
    }
}
