我正在学习 REST Web 服务，对此了解不多。所以我尝试在这里创建一个简单的应用程序
当我从邮递员发送请求时尝试将对象保存到 mongodb 集合时出现 NoSuchMethodError
请求能够到达API。我什至可以访问正在传递的对象，所以我猜 api 没问题。但存储库无法保存对象
错误-

我正在发送的邮递员请求-

请求正文-

"id":"a",
"firstName":"ab",
"lastName":"cd",
"deptName":1
}
对于其他正在寻找答案的人，我设法通过从 build.gradle 中删除依赖项来使其工作
我有一个 mongodb-driver(3.0.1) 依赖项和一个 spring-boot-starter-data-mongodb(2.4.1) 依赖项。我删除了第一个，这就成功了。

NoClassDefFoundError: javax/xml/bind/DatatypeConverter 已删除，请注意 DatatypeConverter 已删除 javax.xml.bind 已删除。 Это происходит, потому что начиная с Java 11, модуль JAXB (Java Architecture for XML Binding), который включает javax.xml.bind, был удален из стандартной библиоте ки 爪哇。 Чтобы решить эту проблему, вам нужно добавить зависимость JAXB в ваш проект. В вашем pom.xml добавьте следующие зависимости:
