spring配置文件注入到静态变量

spring配置注入到静态文件代码如下：

package com.test.oss;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

/**
 * oss账号配置
 *
 * @author shiwen
 */

@Component
@ConfigurationProperties("test.oss")
class OSSConfig {

    /**
     * oss endpoint
     */
    private static String ENDPOINT_;
    private static String BUCKET_NAME;
    private static String BASE_DOWNLOAD_URL;

    /**
     * accessKey
     */
    private static String ACCESS_KEY_ID;

    /**
     * accessKeySecret
     */
    private static String ACCESS_KEY_SECRET;

//    @Value("${alpha-admin.oss.endpoint}")
    public void setEndpoint(String endpoint) {
        ENDPOINT_ = endpoint;
    }

//    @Value("${alpha-admin.oss.bucketName}")
    public void setBucketName(String bucketName) {
        BUCKET_NAME = bucketName;
    }

//    @Value("${alpha-admin.oss.baseDownloadUrl}")
    public void setBaseDownloadUrl(String baseDownloadUrl) {
        BASE_DOWNLOAD_URL = baseDownloadUrl;
    }

//    @Value("${alpha-admin.oss.accessKeyId}")
    public void setAccessKeyId(String accessKeyId) {
        ACCESS_KEY_ID = accessKeyId;
    }

//    @Value("${alpha-admin.oss.accessKeySecret}")
    public void setAccessKeySecret(String accessKeySecret) {
        ACCESS_KEY_SECRET = accessKeySecret;
    }

    /**
     * 获取accessKeyId
     *
     * @return accessKeyId
     */
    static String getAccessKeyId() {
        return ACCESS_KEY_ID;
    }

    /**
     * 获取accessKeySecret
     *
     * @return accessKeySecret
     */
    static String getAccessKeySecret() {
        return ACCESS_KEY_SECRET;
    }

    /**
     * 获取endpoint
     *
     * @return endpoint
     */
    static String getEndpoint() {
        return ENDPOINT_;
    }

    /**
     * 获取  bucketName
     *
     * @return bucketName;
     */
    static String getBucketName() {
        return BUCKET_NAME;
    }

    /**
     * 获取基础下载路径
     *
     * @return 下载路径
     */
    static String getBaseDownloadUrl() {
        return BASE_DOWNLOAD_URL;
    }
}
