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 {@Overridepublic void checkData(Map<String, String> map) {}@Overridepublic String getType() {return null;}
}@Service
public class ZeroTest01ServiceImpl implements ZeroTestService {@Overridepublic void checkData(Map<String, String> map) {}@Overridepublic String getType() {return null;}
}

4.实现IOC容器

@Component
public class ZeroTestServiceFactory implements ApplicationContextAware {@Autowiredprivate ApplicationContext applicationContext;public Map<String, ZeroTestService> serviceMap = new HashMap<>();public ZeroTestService getZeroTestService(String type) {return serviceMap.get(type);}@Overridepublic 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()));}}
}
