Java Hibernate验证程序不计算消息中的EL表达式

我写了一个关于Hibernate验证器的简单示例，参考官方文档

Car.java的代码段如下：

@Size(min = 2, max = 14, message = "The license plate '${validatedValue}' must be between {min} and {max} characters long")
private String licensePlate;

@Min(value = 2, message = "There must be at least {value} seat${value > 1 ? 's' : ''}")
private int seatCount;

@DecimalMax(value = "350", message = "The top speed ${formatter.format('%1$.2f', validatedValue)} is higher "
        + "than {value}")
private double topSpeed;

@Test
public void licensePlateTest()
{
    Car car = new Car( null, "A", 1, 400.123456, BigDecimal.valueOf( 200000 ) );
    String message = validator.validateProperty( car, "licensePlate" )
            .iterator()
            .next()
            .getMessage();
    assertEquals(
            "The license plate must be between 2 and 14 characters long",
            message
    );
}

@Test
public void seatCountTest()
{
    Car car = new Car( null, "A", 1, 400.123456, BigDecimal.valueOf( 200000 ) );
    String message = validator.validateProperty( car, "seatCount" ).iterator().next().getMessage();
    assertEquals( "There must be at least 2 seats", message );
}

下面是CarTest.java的代码片段：

@Size(min = 2, max = 14, message = "The license plate '${validatedValue}' must be between {min} and {max} characters long")
private String licensePlate;

@Min(value = 2, message = "There must be at least {value} seat${value > 1 ? 's' : ''}")
private int seatCount;

@DecimalMax(value = "350", message = "The top speed ${formatter.format('%1$.2f', validatedValue)} is higher "
        + "than {value}")
private double topSpeed;

@Test
public void licensePlateTest()
{
    Car car = new Car( null, "A", 1, 400.123456, BigDecimal.valueOf( 200000 ) );
    String message = validator.validateProperty( car, "licensePlate" )
            .iterator()
            .next()
            .getMessage();
    assertEquals(
            "The license plate must be between 2 and 14 characters long",
            message
    );
}

@Test
public void seatCountTest()
{
    Car car = new Car( null, "A", 1, 400.123456, BigDecimal.valueOf( 200000 ) );
    String message = validator.validateProperty( car, "seatCount" ).iterator().next().getMessage();
    assertEquals( "There must be at least 2 seats", message );
}

licensePlate的验证消息是：“车牌“${validatedValue}”的长度必须介于2到14个字符之间。”

seatCount的验证消息是：“必须至少有2个座位${value>1's'：''}。”

我们可以看到，EL表达式不起作用。关于我的项目的pom.xml是：

<!-- Hibernate Validator -->
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-validator</artifactId>
        <version>4.3.1.Final</version>

我不知道为什么它不起作用，有人能帮我吗？谢谢。

您使用的是Hibernate Validator 4.x版本，它与Bean Validation 1.0保持一致。在4.x版本中，使用表达式语言（EL）的变量插值不可用。这是添加到BeanValidation1.1中的一个特性，因此在HibernateValidator5.x系列中可用。最新的稳定版本是5.1.3.Final。我建议您升级到该版本。

在hibernate 4.3中，您需要指定ValueFormatTermMessageInterpolator作为消息插入器，而不是使用默认值，以便插入${validatedValue}：

Configuration<?> configuration = Validation.byDefaultProvider().configure();
ValidatorFactory factory = configuration
    .messageInterpolator(new ValueFormatterMessageInterpolator(configuration.getDefaultMessageInterpolator()))
    .buildValidatorFactory();

Validator validator = factory.getValidator();

Configuration-Configuration=Validation.byDefaultProvider（）.Configuration（）；
验证工厂=配置
.messageInterpolator（新值FormatTermMessageInterpolator（配置.getDefaultMessageInterpolator（）））
.buildValidatorFactory（）；
Validator Validator=factory.getValidator（）；

我想你是从这里得到的吧？Dit从原始源代码树开始工作？请添加实体注释的导入。嗨，Peter，你能提供更多信息吗？
