本文介绍了一个使用Spring框架进行依赖注入的实例，展示了如何通过注解方式配置服务接口和服务实现类，特别关注了当某些模块未加载时如何正确配置依赖。

在公司做项目中碰到的一些从没有遇到的异常；

公司使用的是注解方式进行sping 的依赖注入；模块间的调用通过接口实现；

这是接口：

里面定义供调用的方法，方法已经被别的模块的类实现；

public interface IFcIntrestDtlService {

public double calculateSumInterest(Date startDate, Date endDate,int interestType,String accTypeCode,String corpCode,String curCode);

List<DecisionFuncValue> calculateSumInterest(Date startDate, Date endDate,int isNetSign);

List<DecisionFuncValue> calculateLxzc(Date startDate, Date endDate, int netSign);
}

这是依赖接口的调入类，调入类负责定义接口调用接口中的方法；

@Transactional
@Service("decisionImportService")
public class DecisionImportService {
    /**
     * 币别service
     */
    @Autowired(required = false)
    private IBtCurrencyService iBtCurrencyService;


    /**
     *
     */
    @Autowired(required = false)
    IBtUserManagerServcies iBtUserManagerServcies;

如果接口中的方法实现不存在，就是别的模块没有被加载进当前项目中。那么就要设置这个属性：在程序启动时不加载这个依赖的接口和模块

@Autowired(required = false)
private IFcIntrestDtlService iFcIntrestDtlService;

@Autowired(required = false)
private IFcAccBalanceService iFcAccBalanceService;

    /**
     *
     */
    @Autowired
    IBtCorpService iBtCorpService;

    /**
     * 网点的service
     */
    @Autowired
    private IBtNetService iBtNetService;

    @Autowired(required = false)
    private IFcSubjectDayService iFcSubjectDayService;

@Autowired(required = false)
private IFcSubjectService iFcSubjectService;

    public IFcSubjectService getIFcSubjectService() {
        return iFcSubjectService;
    }

    public void setIFcSubjectService(IFcSubjectService iFcSubjectService) {
        this.iFcSubjectService = iFcSubjectService;
    }

    public IFcSubjectDayService getIFcSubjectDayService() {
        return iFcSubjectDayService;
    }

    public void setIFcSubjectDayService(IFcSubjectDayService iFcSubjectDayService) {
        this.iFcSubjectDayService = iFcSubjectDayService;
    }

    public IFcIntrestDtlService getIFcIntrestDtlService() {
        return iFcIntrestDtlService;
    }

    public void setIFcIntrestDtlService(IFcIntrestDtlService iFcIntrestDtlService) {
        this.iFcIntrestDtlService = iFcIntrestDtlService;
    }

public IBtCorpService getIBtCorpService() {
return iBtCorpService;
}

    public IFcAccBalanceService getIFcAccBalanceService() {
        return iFcAccBalanceService;
    }

    public void setIFcAccBalanceService(IFcAccBalanceService iFcAccBalanceService) {
        this.iFcAccBalanceService = iFcAccBalanceService;
    }

public void setIBtCorpService(IBtCorpService btCorpService) {
iBtCorpService = btCorpService;
}

public IBtCurrencyService getIBtCurrencyService() {
return iBtCurrencyService;
}

public void setIBtCurrencyService(IBtCurrencyService btCurrencyService) {
iBtCurrencyService = btCurrencyService;
}

public IBtUserManagerServcies getIBtUserManagerServcies() {
return iBtUserManagerServcies;
}

public void setIBtUserManagerServcies(
IBtUserManagerServcies btUserManagerServcies) {
iBtUserManagerServcies = btUserManagerServcies;
}

public IBtNetService getIBtNetService() {
return iBtNetService;
}

public void setIBtNetService(IBtNetService btNetService) {
iBtNetService = btNetService;
}

}
