今天，我正在研究发送电子邮件，但是当我添加时

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context-support</artifactId>
    <version>4.2.5.RELEASE</version>
</dependency>

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>7.0</version>
</dependency>

<dependency>
    <groupId>javax.mail</groupId>
    <artifactId>javax.mail-api</artifactId>
    <version>1.5.5</version>
</dependency>

到 pom.xml 并在服务器上部署时，我收到“无法创建配置，因为找不到 Bean Validation 提供程序。将 Hibernate Validator (RI) 之类的提供程序添加到您的类路径。”验证异常。

我刚刚将上面的依赖项和用于电子邮件的依赖项添加到模板 MVC 项目中。

最佳答案

添加一个 Bean Validation Provider 依赖，例如 Hibernate Validator。 Bean Validation API 依赖项在类路径上可用，但缺少实现。将以下内容添加到您的 pom.xml

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>5.2.4.Final</version>
</dependency>

关于spring - 无法创建配置，因为找不到 Bean 验证提供程序。将像 Hibernate Validator (RI) 这样的提供程序添加到您的类路径中，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/36329001/
