Question

我有用户实体，我在测试中尝试验证字段密码的长度。

我的用户类：

public class User {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Integer id;

    @Column(name = "email", length = 100, nullable = false, unique = true)
    @NotEmpty
    @Email
    private String email;

    @Column(name = "password")
    @NotEmpty
    @Size(min = 5, max = 6)
    private String password;
}

我尝试了3种变体。

1.密码长度＆lt; 5

@Test
public void passwordIsShort() {
    User user = new User();
    user.setPassword("1");

    Set<ConstraintViolation<User>> constraintViolations = validator.validateProperty(user, "password");

    assertEquals(1, constraintViolations.size());
}

此测试不起作用并显示错误。

2.密码长度为5和6时

@Test
public void passwordIsShort() {
    User user = new User();
    user.setPassword("12345");

    Set<ConstraintViolation<User>> constraintViolations = validator.validateProperty(user, "password");

    assertEquals(0, constraintViolations.size());
}

此测试工作正确。

3.密码长度＆gt; 6

@Test
public void passwordIsShort() {
    User user = new User();
    user.setPassword("1234567");

    Set<ConstraintViolation<User>> constraintViolations = validator.validateProperty(user, "password");

    assertEquals(1, constraintViolations.size());
}

此测试不起作用，也显示错误

错误：

UPD

我用

java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) Client VM (build 24.51-b03, mixed mode, sharing)

Answer 1

我很惊讶任何测试都能奏效。您的异常表示您的类路径上具有错误版本的Unified Expressions语言依赖项。另请参阅https://github.com/hibernate/hibernate-validator和http://docs.jboss.org/hibernate/stable/validator/reference/en-US/html_single/#validator-gettingstarted-uel

我想问题就在于您正在运行的环境以及您正在使用的EL依赖项（如果有）。

Answer 2

我意识到帖子有点陈旧，可能已经解决了。如果其他人遇到同样的问题，只是想更新。正如Mufanu在评论中添加的那样，如果我们在注释中添加消息属性

，这将解决

@not null在没有消息的情况下正常工作

@Size（min = 5，max = 6， message = ＆＃34;尺寸必须介于5到6＆＃34之间;）
私有字符串密码;

Hibernate验证错误 - @Size
