我所有的 Spring Boot 项目都突然不工作了。我创建了一个新的 Spring Boot 项目，没有添加任何类。启动项目时仍然出现错误。

我检查了现有的类似错误，但它始终与代码有关。就我而言，没有添加代码。

PS : 我想我在 brew update 后遇到了错误，但我看不到关系

我已经编辑了项目。实际上，这个项目运行良好。现在我认为spring依赖项有混淆

【问题讨论】：

这个stackoverflow.com/a/21656166/4601373 可能会解决您的问题。
你能加你application.properties文件吗？
hibernate-validator-6.1.7.Final.jar 可能已损坏，导致 org.hibernate.validator.internal.engine.valueextraction.ValueExtractorManager 无法初始化。尝试从 Maven 的缓存中删除 jar 并重新构建您的应用程序。
重新加载项目依赖。另外，尝试为 H2 数据库添加属性 spring.datasource.url=jdbc:h2:mem:testdb #spring.datasource.driverClassName=org.h2.Driver spring.datasource.username=sa spring.datasource.password=password spring。 jpa.database-platform=org.hibernate.dialect.H2Dialect
@AndyWilkinson 我已经删除了 .m2 目录，但错误仍然存在

标签： java spring spring-boot hibernate spring-mvc

【解决方案1】：

您一次添加多个依赖项，而不是在application.properties 中添加所需的配置类和所需的配置。这就是它导致错误的原因。

创建项目最小依赖项（如 spring-web 和 dev-tools）。
使用简单的 Hello word REST-API 测试。
如果它正常工作，则添加下一个依赖项，依此类推。

逐步创建，最后添加安全性（安全性需要大量配置）。

【解决方案2】：

您已添加 pring-boot-starter-data-jpa 依赖项，但未进行数据库配置。
如果您只想运行它，请删除 pring-boot-starter-data-jpa 依赖项，当您配置数据库访问权限时，您可以导入 pring-boot-starter-data-jpa 依赖项。
