Service层代码中添加了@Value注解启动异常_service 里注入value-优快云博客

在SpringBoot项目中，Service层添加@Value注解导致启动时出现异常。问题描述显示，仅此改动即触发错误。经过原因分析，可能是与Lombok的@AllArgsConstructor注解冲突。解决方案是移除@AllArgsConstructor，保留@Service、@Slf4j，并通过@Resource注解注入依赖。目前未找到根本原因，期待有经验者提供解答。

问题复现：

SpringBoot项目的service层，添加了@Value注解

	@Value("${com.****.****.****.uploadUrl}")
    private String uploadUr ;

导致项目启动时，抛出异常，异常如下：

问题描述

其他地方不动，只是添加了@Value注解（相应配置已添加），启动就会报以下错误，
