一旦我创建了一个名为 entity 的包并在 application.yml 中添加了一些配置，就会出现错误

application.yml 看起来像这样

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/mydb
    username: root
    password:
  jpa:
    show-sql: true
    hibernate:
      ddl-auto: update
      naming:
        strategy: org.hibernate.cfg.ImprovedNamingStrategy
    properties:
      hibernate:
        dialect: org.hibernate.dialect.MySQL5Dialect

我尝试使用“mvn clean install”重建项目我尝试从 maven 依赖项中删除所有 *.jar，并使用 maven funcionalities 中的“更新项目”。

我的 pom.xml 看起来像这样：

我是 spring mvc、maven 和 spring boot 的新手。任何帮助将不胜感激。

** 更新 ** 顺便说一句，我使用的是 Eclipse neon 2

【问题讨论】：

你要使用hibernate 5吗？
好吧，正如错误清楚地表明：找不到 Hibernate 类。实际上，您没有在 pom 中列出任何休眠依赖项。
尝试dependency:purge-local-repository，然后执行mvn clean package（或install）。这将清除本地 Maven 存储库并再次尝试下载。
应该是 mvn dependency:purge-local-repository 这是一个 Maven 目标（不知道为什么我忘记了 mvn 部分）。
可能是本地存储库中有错误的 jar，有时会在下载工件时发生。清理存储库并再次下载工件通常会有所帮助。

标签： spring-mvc spring-boot

【解决方案1】：

如果您确定在 pom.xml 中定义了所有正确的依赖项，则可能是本地 maven 存储库中的错误 jar 或 pom。

您可以使用以下命令清除本地存储库

mvn dependency:purge-local-repository

这将从本地存储库中删除所有项目依赖项，当再次重建 (mvn package) 时，依赖项将被解析并再次下载。

您还可以指定一些附加标志（请参阅this question 和official documentation）。

【讨论】：

执行此操作后，Intellij 无法再解析 Spring 的依赖关系。
它破坏了我的项目
您将需要刷新依赖项，因为这会将它们从您的存储库中删除（这就是清除的意思）。

【解决方案2】：

我是弹簧靴的新手。我创建了一个简单的 spring-boot 应用程序并面临同样的问题。我刚刚在 pom 中将父版本从 1.4.3 更新为 1.5.3 并且成功了！

<parent>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-parent</artifactId>
  <version>1.5.3.RELEASE</version>
</parent>

注意：我只是想让你知道我使用的是 java 版本 10。

【讨论】：

你救了我的命。这对我来说非常有用。我正在使用 Java 11。
这对我也有用，我有 1.3.1 并将其更新为 1.5.3

【解决方案3】：

将父版本从 1.4.3 更新到 1.5.3 修复了“无法启动嵌入式容器”的问题，如果需要“实时重新加载”，则需要添加“spring-boot-devtools”，如下所示，其中包括一个嵌入式 LiveReload 服务器，用于在资源更改时触发浏览器刷新，因此您需要将父版本更新为 2.1.13

【讨论】：

将版本从 1.4.3 更新到 1.5.3 对我有用。谢谢。

【解决方案4】：

我也有同样的错误，解决方案只是升级到今天最新版本的 spring-boot starter-parent。谢谢
