My DTO class:
```java
package dk.xakeps.truestarter.server.dto.request;
import com.fasterxml.jackson.annotation.JsonCreator;
import com.fasterxml.jackson.annotation.JsonProperty;
import dk.xakeps.truestarter.server.validator.CrossField;
import javax.annotation.Nonnull;
import javax.validation.constraints.Email;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;
@CrossField(fields = {"password", "passwordRetry"})
public class RegisterRequest {
@NotNull
@Email
@Size(max = 150)
private final String email;
@NotNull
@Size(min = 3, max = 16)
private final String username;
@NotNull
@Size(min = 6, max = 32)
private final String password;
@NotNull
@Size(min = 6, max = 32)
private final String passwordRetry;
@JsonCreator
public RegisterRequest(@Nonnull @JsonProperty("email") String email,
@Nonnull @JsonProperty("username") String username,
@Nonnull @JsonProperty("password") String password,
@Nonnull @JsonProperty("passwordRetry") String passwordRetry) {
this.email = email;
this.username = username;
this.password = password;
this.passwordRetry = passwordRetry;
}
public String getEmail() {
return email;
}
public String getUsername() {
return username;
}
public String getPassword() {
return password;
}
public String getPasswordRetry() {
return passwordRetry;
}
}
```
CrossField annotation:
```java
package dk.xakeps.truestarter.server.validator;
import javax.validation.Constraint;
import javax.validation.Payload;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
@Target({ElementType.TYPE, ElementType.ANNOTATION_TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Constraint(validatedBy = CrossFieldValidator.class)
public @interface CrossField {
String message() default "{CrossField.message}";
Class<?>[] groups() default {};
Class<? extends Payload>[] payload() default {};
String[] fields();
}
```
CrossField validator:
```java
*package dk.xakeps.truestarter.server.validator;
import org.apache.commons.beanutils.PropertyUtils;
import javax.validation.ConstraintValidator;
import javax.validation.ConstraintValidatorContext;
import javax.validation.ValidationException;
import java.lang.reflect.InvocationTargetException;
public class CrossFieldValidator implements ConstraintValidator<CrossField, Object> {
private String[] fields;
@Override
public void initialize(CrossField constraintAnnotation) {
this.fields = constraintAnnotation.fields();
}
@Override
public boolean isValid(Object value, ConstraintValidatorContext context) {
Object prevFieldValue = null;
int i = 0;
for (String field : fields) {
try {
Object property = PropertyUtils.getProperty(value, field);
if (i == 0) {
prevFieldValue = property;
i++;
continue;
}
if (!prevFieldValue.equals(property)) {
return false;
}
prevFieldValue = property;
i++;
} catch (IllegalAccessException | InvocationTargetException | NoSuchMethodException e) {
throw new ValidationException("Failed validating bean", e);
}
}
return true;
}
}
```
