说明：
绑定到目标[Bindable@6bff19ff类型=java.lang.String，值='provided'，注释=数组[[empty]]]]失败：
属性：spring.datasource.password
值：${password}
来源：类路径资源[应用程序.属性]：7:28
原因：无法解析值“${password}”中的占位符“password”
行动：
更新应用程序的配置

您似乎尚未声明您试图在“spring.datasource.password”属性中使用的属性“password”（或其声明有问题）。

---

但是，如果看不到整个属性文件，就很难说清楚。

您必须打开maven资源插件的筛选功能。您必须在POM中添加一个

标记，并将其设置为

true

在“流程资源”阶段，maven可能需要用真实密码替换

${password}

变量
