如何将javax.validation导入Java SE项目？

Question

我正在尝试添加约束检查,如下所述如何在EclipseLink/JPA中指定@OneToMany的基数

Answer 1

以下是我正在使用的依赖项(使用Maven):

<dependencies>
  <!-- Bean Validation API and RI -->
  <dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>1.0.0.GA</version>
  </dependency>
  <dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>4.0.2.GA</version>
  </dependency>
</dependencies>

您可以从此存储库获取:

<repositories>
  <repository>
    <id>jboss</id>
    <name>JBoss repository</name>
    <url>http://repository.jboss.org/maven2</url>
  </repository>
</repositories>

Answer 2

最新的依赖:

<dependency>
    <groupId>org.hibernate.validator</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>6.0.16.Final</version>
</dependency>

这种传递性依赖于Bean Validation API,因此您不再需要这样做:

<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>1.1.0.Final</version>
</dependency>

有关表达式语言和CDI支持的其他功能,您可能需要添加

<dependency>
    <groupId>org.glassfish</groupId>
    <artifactId>javax.el</artifactId>
    <version>3.0.1-b09</version>
</dependency>

<dependency>
    <groupId>org.hibernate.validator</groupId>
    <artifactId>hibernate-validator-cdi</artifactId>
    <version>6.0.16.Final</version>
</dependency>

这些都都在Maven Central Repo中,所以你不需要添加JBoss repo.

BTW这是我的示例便捷方法:

public static <T extends Object> void  validate( T object ) throws MigrationException
{
    ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
    Validator validator = factory.getValidator();
    Set<ConstraintViolation<T>> valRes = validator.validate( object );
    if( ! valRes.isEmpty() )
    {
        StringBuilder sb = new StringBuilder("Validation failed for: ");
        if( object instanceof Origin.Wise )
            sb.append( ((Origin.Wise)object).getOrigin() );
        else
            sb.append(object);

        for( ConstraintViolation<T> fail : valRes)
        {
            sb.append("\n  ").append( fail.getMessage() );
        }
        throw new IllegalArgumentException( sb.toString() );
    }
}

该Origin.Wise有点像JAXB的@XmlLocation Locator.
