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

Question

我加入的依赖于spring-boot-starter-data-jpa和spring-boot-starter-jdbc和mysql-connector-java。

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2.3.0.RELEASESpring Boot Web 和 WebFlux 启动器版本开始不再依赖验证启动器，spring-boot-starter-validation应明确添加到 pom.xml。

Spring Boot 2.3 发行说明

Answer 2

确保spring-boot-starter-web您的 pom 中有依赖项作为javax.validation它的一部分..并运行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>
