读取properties配置的工具类

@Service
public class AppPropertiesManager implements DisposableBean{
    @Value("${shortloan_rate_1}")
    private  Double shortloanRate1Year;

    @Value("${longloan_rate_1_5}")
    private  Double longloanRate1to5Year;

    private  Double fcffT;

    private Double risk_premium;

    public Double getRisk_premium() {
        return risk_premium;
    }

    public void setRisk_premium(Double risk_premium) {
        this.risk_premium = risk_premium;
    }

    public String getGuidDomain() {
        return guidDomain;
    }

    public void setGuidDomain(String guidDomain) {
        this.guidDomain = guidDomain;
    }

    @Value("${cookie_guid_domain}")
    private  String guidDomain;

    public Double getFcffT() {
        return fcffT;
    }

    public void setFcffT(Double fcffT) {
        this.fcffT = fcffT;
    }

    public Double getShortloanRate1Year() {
        return shortloanRate1Year;
    }

    public void setShortloanRate1Year(Double shortloanRate1Year) {
        System.out.println(shortloanRate1Year);
        this.shortloanRate1Year = shortloanRate1Year;
    }

    public Double getLongloanRate1to5Year() {
        return longloanRate1to5Year;
    }

    public void setLongloanRate1to5Year(Double longloanRate1to5Year) {
        this.longloanRate1to5Year = longloanRate1to5Year;
    }

    @Override
    public void destroy() throws Exception {
        System.out.println(longloanRate1to5Year);

在web工程中，部署时，properties通常在WEB-INF\classes下，与class文件同级，该工具类可以是在jar包里面，可以正常读取到properties。
