[英]Error creating bean with name 'spring.datasource.CONFIGURATION_PROPERTIES'
我在启动Spring Boot Project时遇到错误，下面是Exception片段
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.
at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor.postProcessPropertyValues(AutowiredAnnotationBeanPostProcessor.java:334)
at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.populateBean(AbstractAutowireCapableBeanFactory.java:1214)
at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:543)
尝试@Autowired java.sql.Datasource bean时发生错误。
但是，通过包含Hibernate Validator依赖项解决了该问题
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
</dependency>
pom.xml片段
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.3.RELEASE</version>
<relativePath/>
</parent>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<java.version>1.7</java.version>
<querydsl.version>4.0.1</querydsl.version>
</properties>
<dependencies>
<dependency>

<artifactId>spring-boot-starter</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
</dependency>
<dependency>
<groupId>org.hsqldb</groupId>

<dependency>
<groupId>com.querydsl</groupId>
<artifactId>querydsl-sql-codegen</artifactId>
<version>${querydsl.version}</version>
<scope>provided</scope>
</dependency>
</dependencies>
我担心的是为什么有必要包含hibernate-validator ，如果有必要，为什么它不作为spring-boot-starter-jdbc的传递依赖包含？

实际的罪魁祸首是querydsl-sql因为它querydsl-sql了validation-api querydsl-sql 。 validation-api存在依次打开属性验证。
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。 这是不可用的，所以你得到一个错误。 要修复你有两个选择。
hibernate-validator包含为依赖项（这可以正常工作） querydsl-sql依赖项中排除validation-api 。 两种解决方案都可行。 第一个好处是Spring Boot现在可以检测配置中的错误，而没有它不能。 缺点是你有另一个依赖。
你可以分别使用Hibernate和Spring的验证器。 如果在代码中实现@Valid注释，则告诉VM首先由Hibernate和Spring进行验证。
您可以通过实现@Valid注释来阻止Hibernate验证。
