Could not resolve placeholder 'token.header' in value "${token.header}"

Could not resolve placeholder ‘token.header’ in value "${token.header}"是Spring Boot项目启动时的错误信息，这个错误通常是因为配置文件中的占位符没有正确地解析导致的。占位符的格式应该是${key}，其中key是对应配置文件中的属性名。在这个错误信息中，'token.header'是一个占位符，指示应该从配置文件中获取名为token.header的属性值，但是在配置文件中找不到对应的属性，所以就无法解析占位符，最终导致错误的发生。要解决这个问题，可以检查配置文件中是否存在名为token.header的属性，并确保其值被正确设置。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
