SpringBoot详解如果通过@Value注解给静态变量注入值

@Component
public class JDConfig {
    /** 转换系统地址 */
    public static String url;
    /** 转换系统应用系统id */
    public static String sysId;
    /** 是否开启鉴权 */
    public static Boolean isAuth;
    /** 转换系统应用系统秘钥（如开启鉴权需要填写） */
    public static String sysKey;
    @Autowired(required = false)
    @Value(value="${jd.serverHost:}")
    public void setUrl( String url) {
        JDConfig.url = url;
    }
    @Autowired(required = false)
    @Value(value="${contract.jd.appKey:}")
    public void setSysId( String sysId) {
        JDConfig.sysId = sysId;
    }
    @Autowired(required = false)
    @Value(value="${jd.isAuth:true}")
    public void setAuth(Boolean isAuth) {
        JDConfig.isAuth = isAuth;
    }
    @Autowired(required = false)
    @Value(value="${contract.jd.appSecurity:}")
    public void setSysKey(String sysKey) {
        JDConfig.sysKey = sysKey;
    }
    public  String getUrl() {
        return url;
    }
    public  String getSysId() {
        return sysId;
    }
    public  Boolean getIsAuth() {
        return isAuth;
    }
    public  String getSysKey() {
        return sysKey;
    }
}

    @Value("${projectCode}")
    private String projectCode;
    public static String COOPERATIVE_GOV_TEMPLATE_KEY ;
    // 消息短信配置
    public static String DEPOLY_KEY;
    // 消息短信详情配置
    public static String MSG_DEPOLY_KEY;
    // 过滤配置
    public static String MSG_FILTER_KEY;
    @PostConstruct
    public void init() {
        COOPERATIVE_GOV_TEMPLATE_KEY = projectCode + ":template";
        DEPOLY_KEY = projectCode + ":depoly";
        MSG_DEPOLY_KEY = projectCode + ":msgDepoly";
        MSG_FILTER_KEY = projectCode + ":msgFilter";
    }
