Question

我为spring-boot-starter-data-jpa和spring-boot-starter-jdbc和mysql-connector-java添加了依赖性。

我遇到了问题："missing artifact javax .validation:validation-api:jar:2.0.1 final.“

我该如何解决？

Answer 1

从版本2.3.0.RELEASE开始，Spring Boot Web和WebFlux启动器不再依赖于验证启动器，应将spring-boot-starter-validation明确地添加到pom.xml中。

Answer 2

确保pom中具有spring-boot-starter-web依赖项，因为javax.validation是其中的一部分。然后运行mvn clean install一次以重新加载所有依赖项。

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

在此处查看网络依赖关系树。.javax.validation:validation-api:jar:2.0.1.Final

Answer 3

这就是我解决问题的方法：

<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>2.0.1.Final</version>
</dependency>

Here the dependency

缺少工件javax .validation：validation-api：jar：2.0.1 final
