Hibernate Validation 不在 Spring Boot 应用程序中查找错误消息

Question

这是我设置的 Spring Boot 项目。

我有一个标准的 Spring Boot JPA 堆栈，我试图在其中验证实例变量的状态。我的豆子如下：

配置

@Component
public class ConfigurationHelper {

    @Bean
    public MessageSource messageSource() {
        ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
        messageSource.setBasenames("messages");
        messageSource.setUseCodeAsDefaultMessage(true);
        messageSource.setCacheSeconds(5);
        messageSource.setDefaultEncoding("UTF-8");
        return messageSource;
    }

    @Bean
    public Validator validator() {
        LocalValidatorFactoryBean factoryBean = new LocalValidatorFactoryBean();
        factoryBean.setValidationMessageSource(this.messageSource());
        return factoryBean;
    }
}

模型类

@Table(name = "user_station", indexes = {
    @Index(columnList = "station_id", name = "station_index_station_id"),
    @Index(columnList = "station_name", name="station_index_name"),
    @Index(columnList = "hd_enabled", name = "station_index_hd_enabled")
})
@Entity
@EqualsAndHashCode(exclude = {"createdTimeStamp", "updatedTimestamp"}, callSuper = true)
@ToString(exclude = {"createdTimeStamp", "updatedTimestamp"}, callSuper = true)
@JsonInclude(JsonInclude.Include.NON_NULL)
public class Station extends IError {

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

    // Represents a station id for the user.
    @Column(name="station_id", nullable = false, unique = true)
    @NotEmpty(message = "{station.id.empty}")
    @Pattern(regexp = "^K|W[A-Za-z0-9\\-].*$", message = "{station.id.name.not.valid}")
    private String stationId;

    @Column(name="station_name", nullable = false)
    @JsonProperty("name")
    @NotEmpty(message = "{station.name.empty}")
    private String stationName;

    @Column(name = "hd_enabled")
    private Boolean hdEnabled;

    @Column(name="call_sign", nullable = false)
    @NotEmpty(message = "{station.call.sign.empty}")
    private String callSign;

    @Column(name="user_created_timestamp")
    @JsonIgnore
    private LocalDateTime createdTimeStamp;

    @Column(name="user_modified_timestamp")
    @JsonIgnore
    private LocalDateTime updatedTimestamp;

    /**
     * Initialises the timestamps prior to update or insertions.
     *
     * <p>The implementation ensures that time stamps would always reflect the time when entities
     * were persisted or updated.
     */
    @PrePersist
    @PreUpdate
    public void setTimestamps() {
        LocalDateTime utcNow = LocalDateTime.now(ZoneOffset.UTC);
        if (this.createdTimeStamp == null) {
            this.createdTimeStamp = utcNow;
        }
        this.updatedTimestamp = utcNow;
        if (this.hdEnabled == null) {
            this.hdEnabled = Boolean.FALSE;
        }
    }

    // Getters, Setters, Equals and HashCode functions.
}

单元测试

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes= {App.class})
public class StationTest {

    @Autowired
    private Validator validator;

    private Station station;

    @Before
    public void setUp() throws Exception {
        this.station = new Station();
    }


    @Test
    public void testValidator_allNulls() {
        Set<ConstraintViolation<Station>> constraintViolations =
            this.validator.validate(this.station);
        MatcherAssert.assertThat(constraintViolations.isEmpty(), Is.is(false));
        for (ConstraintViolation<Station> constraintViolation : constraintViolations) {
            System.out.println(constraintViolation.getMessage());
        }
    }
}

这是我的输出

我已阅读以下内容

1. Custom error messaging on Hibernate Validation

2. Custom Message Key in Hibernate validator not working with message.property

3. Does Spring Boot automatically resolve message keys in javax and hibernate validation annotations

但我仍然无法弄清楚我做错了什么。

更新

根据@Jonathan Johx 的建议，我将 ResourceBundleMessage 的基本名称更改为messages（也更新了代码 sn-p），但仍然出现错误。

Answer 1

问题是因为 classpath: 确实引用了 ConfigurationHelper 类的文件夹的根目录，但没有找到。尝试将文件名重命名为 Validator 使用的 ValidationMessages.properties 并更新以下行：

messageSource.setBasenames("ValidationMessages"); 

更新

如果您想默认使用验证消息，那么您必须创建一个名为：

ValidationMessages.properties

并添加您认为必要的属性。
