创建名称为 'spring.datasource.CONFIGURATION_PROPERTIES' 的 bean 时出错
Error creating bean with name 'spring.datasource.CONFIGURATION_PROPERTIES'
我在启动我的 Spring 启动项目时遇到错误，异常片段如下
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'spring.datasource.CONFIGURATION_PROPERTIES': Initialization of bean failed; nested exception is javax.validation.Validation
Exception: Unable to create a Configuration, because no Bean Validation provider could be found. Add a provider like Hibernate Validator (RI) to your classpath.

尝试 @Autowired java.sql.Datasource bean 时发生错误。
但是，通过包含 Hibernate Validator 依赖关系解决了这个问题

您可以分别使用 Hibernate 和 Spring 的验证器。
如果你在你的代码中实现 @Valid 注释，你告诉 VM 验证将首先由 Hibernate 然后 Spring.
您可以通过取消实现 @Valid 注释来阻止 Hibernate 验证。

真正的罪魁祸首是 querydsl-sql，因为它正在拉入 validation-api。 validation-api 的存在反过来会打开属性验证。
但是，顾名思义，validation-api 只是 API，您仍然需要一个实现来启用验证。那不可用，因此您会收到错误消息。要修复您有 2 个选项。
- 包括
hibernate-validator 作为依赖项（如您所见有效）
- 从
querydsl-sql 依赖项中排除 validation-api。
这两种解决方案都行得通。第一个的好处是 Spring Boot 现在可以检测您的配置中的错误，而没有它则不能。缺点是你又有了另一个依赖。
我在启动我的 Spring 启动项目时遇到错误，异常片段如下
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'spring.datasource.CONFIGURATION_PROPERTIES': Initialization of bean failed; nested exception is javax.validation.Validation

您可以分别使用 Hibernate 和 Spring 的验证器。
如果你在你的代码中实现 @Valid 注释，你告诉 VM 验证将首先由 Hibernate 然后 Spring.
您可以通过取消实现 @Valid 注释来阻止 Hibernate 验证。

真正的罪魁祸首是 querydsl-sql，因为它正在拉入 validation-api。 validation-api 的存在反过来会打开属性验证。
但是，顾名思义，validation-api 只是 API，您仍然需要一个实现来启用验证。那不可用，因此您会收到错误消息。要修复您有 2 个选项。
- 包括
hibernate-validator作为依赖项（如您所见有效） - 从
querydsl-sql依赖项中排除validation-api。
这两种解决方案都行得通。第一个的好处是 Spring Boot 现在可以检测您的配置中的错误，而没有它则不能。缺点是你又有了另一个依赖。
