【问题描述】：
当我开始将项目部署到 Tomcat 上时，我收到错误消息
说明：绑定属性失败 'spring.jackson.deserialization' 到 java.util.Map
: 原因：没有找到能够从类型 [java.lang.String] 转换为类型 [java.util.Map ] 的转换器操作： 更新应用程序的配置
我的 application.properties 是空的
通过 gradle 构建项目。

我的错误在哪里？
【问题讨论】：
-
Update your application's configuration表示配置有问题。能否列出所有配置文件及其包含的内容？ -
您好，“更新应用程序的配置”是什么意思？如果您的意思是 application.properties，则该文件为空。抱歉，这是我在 Spring 中的第一步，我不确定我是否正确理解了您的要求。
-
Update your application's configuration是我在您问题的异常消息中看到的内容。这可能是Spring提出的建议操作。如果此文件为空，请尝试设置至少一个属性并检查会发生什么。例如：spring.jackson.deserialization.fail-on-unknown-properties = true -
嗨，我刚刚将此参数添加到 application.properties。没有影响。我收到新的错误消息
