java - Spring Boot抛出java.io.EOFException异常:由于输入结束，没有内容可以映射到Object

我正在做一个测试REST的Spring Boot项目。
REST服务添加，删除，更新并从内存映射中获取患者详细信息。

虽然我可以使用http://localhost:8443/restws/patientservice/patients（GET）这样的通用URL来获取，添加和删除患者

以下路径参数URL不起作用
http://localhost:8443/restws/patientservice/patients/ {123}

以下是我已实现的pom.xml，接口和服务代码

最佳答案

这似乎是因为您试图在构造函数中调用init（）方法，但是存储库还没有机会被注入。

尝试从构造函数中删除方法调用，并向其添加@PostContruct批注。
