包org.springframework.data.repository不存在spring boot jpa答案

【问题标题】：package org.springframework.data.repository does not exist spring boot jpa包org.springframework.data.repository不存在spring boot jpa
【发布时间】：2017-09-11 13:57:32
【问题描述】：

我对 spring boot + jpa 有一个小问题。我已将依赖项添加到 POM.xml，我可以从 spring 工具套件正常运行它（作为 spring boot 应用程序运行）。但是当我从命令行“mvn spring-boot:run”运行时，它会抛出错误。

当我从命令行运行应用程序时，我应该传递任何特殊参数吗？这只是一个简单的应用程序，当我从 STS 运行时，该功能可以正常工作，但我只是想更好地了解 STS 和命令行在运行应用程序时是否有不同的参数。

【问题讨论】：

标签： java spring maven spring-boot spring-data-jpa

【解决方案1】：

您必须删除 .m2 文件夹并更改依赖项的版本并重试更新 maven 项目。

【讨论】：

没有找到'org.springframework.data.repository.CrudRepository'的库
基于操作系统的.m2目录位置 --> Windows: C:/Users//.m2 Linux: /home//.m2 Mac: /Users/ /.m2

【解决方案2】：

在我的情况下，我有两次依赖：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

和

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
    <scope>test</scope>
</dependency>

删除第二个后，由于我在测试之外需要它，错误消失了。

【讨论】：

【解决方案3】：

这一行是您问题的根本原因：

[警告] org.springframework:spring-jdbc:jar:4.3.7.RELEASE 的 POM 无效，传递依赖（如果有）将不可用，请启用调试日志以获取更多详细信息

我认为它来自您的 Maven 设置或命令行中的 java 版本。

【讨论】：

你能具体点吗？我的java版本“1.8.0_77”我也将java_home指向了那个jdk。已尝试使用该依赖错误进行谷歌搜索，但没有运气。
您可以在完全调试模式下重新运行 > 使用 -X 开关重新运行 Maven 以启用完全调试日志记录。
我已经使用 -X 运行，但我无法在此处更新该日志，因为它很长。好的，我发现了问题。
对不起，我点击进入，它会发表我的评论。使用 -X 参数重新运行后，我可以看到更清晰的错误消息。它是由损坏的 pom 文件引起的。一旦我还发布了与没有类发现错误有关的问题，结果证明是由损坏的 jar 引起的。我的问题是如何验证我的本地 Maven 存储库是否处于完美状态？谢谢

【解决方案4】：

我使用带有 -X 参数的 maven 命令重新运行，因此它将打开调试日志记录。

然后错误得到更清晰的错误信息

我删除了整个文件夹，使用命令行运行应用程序，它会重新下载所有需要的 pom 和 jar。应用程序现在可以从命令行正常运行了。

【讨论】：

【解决方案5】：

您似乎下载了以下 pom 错误：

[WARNING] The POM for org.springframework:spring-jdbc:jar:4.3.7.RELEASE is invalid, transitive dependencies (if any) will not be available, enable debug logging for more details
[WARNING] The POM for org.jboss:jandex:jar:2.0.0.Final is invalid, transitive dependencies (if any) will not be available, enable debug logging for more details
[WARNING] The POM for org.springframework.data:spring-data-jpa:jar:1.11.1.RELEASE is invalid, transitive dependencies (if any) will not be available, enable debug logging for more details

我已经看到当 Maven 最终下载 HTML 错误页面而不是工件时会发生这种情况。您可以尝试在 ~/.m2/repository 删除本地 Maven 存储库，然后从命令行构建。
