运行 Spring 应用程序问题答案

【问题标题】：Running Spring application issue运行 Spring 应用程序问题
【发布时间】：2019-01-29 15:20:11
【问题描述】：

我有一个我正在从事的项目的微服务架构，最近我使用的是 Eclipse STS，每当我运行我的一个应用程序微服务时 我使用上下文菜单中的作为 spring boot 应用程序运行

昨天我想试验 Visual Studio Code，所以为了运行我的应用程序，我尝试使用 .\mvnw 或 mvn spring-boot:run 使用 powershell 终端，但不幸的是，在我的一项服务上，它运行不正确，我有以下异常

Exception in thread "main" java.lang.Error: Unresolved compilation problem: 

    at demo.ClientApplication.main(ClientApplication.java:70)

所需项目有以下pom.xml

我应该怎么做才能从 vs-code 作为 maven 命令运行来解决这个问题？（以另一种方式重现 STS 用来成功启动我的应用程序的生成的 maven 命令）

在 ugur 评论之后，我尝试了 mvn clean compile 我遇到以下编译错误

编译器似乎无法识别我添加的 data-shema 依赖项所以我关闭这个线程并打开另一个如果我不解决这个问题

【问题讨论】：

你确定你的代码在编译之前没有错误吗？.. 当你通过 VS 代码运行这个版本时，它可以工作吗？
也许你可以尝试 mvn clean compile 然后再次运行
@Mark 当我使用 Eclipse STS 时，我确实运行了我的应用程序，我可以打印并执行我去年为此开发的每一项任务，我确信没有代码错误，从 eclipse 运行但从 vsc 无法使用 shell
@ugur 感谢异常已更改
你是不是通过com.mds.shema之类的VS代码手动添加依赖，而没有添加到pom.xml中？

标签： java spring maven spring-boot

【解决方案1】：

我使用 SharedCode 项目在我的微服务之间共享我的 feign 客户端和 dto兼容spring boot 2.x.x

因为我是上一个feign版本，所以设置feign请求方法的时候param值不是必须的

但由于我的 SharedCode 使用 maven pom 依赖项链接到我的其他微服务，所以我犯了一个错误，即在 spring boot 1.5.6 上创建我的微服务并添加了所有需要的扫描和类配置

在这里我得到了错误，因为当 spring 扫描 feign 客户端时，它将使用当前项目版本，其中 feign 参数值对于任何引发编译问题的请求签名都是强制性的，而这从未在 SharedCode 项目单独编译中抛出
