问题
I have User entity and I try validate field password for length in my test.
My User Class:
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;
}
There are 3 variants that I try.
1.When password's length < 5
@Test
public void passwordIsShort() {
User user = new User();
user.setPassword("1");
Set<ConstraintViolation<User>> constraintViolations = validator.validateProperty(user, "password");
assertEquals(1, constraintViolations.size());
}
This test doesn't work and shows error.
2.When password's length beetwen 5 and 6
@Test
public void passwordIsShort() {
User user = new User();
user.setPassword("12345");
Set<ConstraintViolation<User>> constraintViolations = validator.validateProperty(user, "password");
assertEquals(0, constraintViolations.size());
}
This test works correct.
3.When password's length > 6
@Test
public void passwordIsShort() {
User user = new User();
user.setPassword("1234567");
Set<ConstraintViolation<User>> constraintViolations = validator.validateProperty(user, "password");
assertEquals(1, constraintViolations.size());
}
This test doesn't works and shows error too

UPD
I use
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)
回答1:
I am surprised that any of the tests would work. Your exception indicates that you have the wrong version of the Unified Expressions Language dependencies on your classpath. See also https://github.com/hibernate/hibernate-validator and http://docs.jboss.org/hibernate/stable/validator/reference/en-US/html_single/#validator-gettingstarted-uel
I guess the question becomes in which environment you are running and which EL dependencies (if any) you are using.

I realize the post is bit old and probably resolved. Just wanted to updated anyway if someone else encounter the same issue. As Mufanu added in the comment this will resolve if we add message attribute in the annotation
@not null works fine without message
@Size(min = 5, max = 6, message = "size must be between 5 and 6")
private String password;
