Java hibernate 找不到布尔值的验证器

Chr*_*onn 2 java validation spring annotations hibernate

我有一个服务方法,它尝试使用store()休眠方法添加一个对象。get 方法适用于此 DAO 和服务类,而添加不起作用。在控制台中没有错误。

UrlWhiteListDaoImpl urlDao;

MapperFacade mapper;

@Autowired
public UrlWhiteListingServiceImpl(UrlWhiteListDao urlWhiteListDao, MapperFacade mapper, UrlWhiteListDaoImpl urlDao) {
    this.urlDao = urlDao;
    this.urlWhiteListDao = urlWhiteListDao;
    this.mapper = mapper;
}

@Override
public UrlWhiteListDto addUrlWhiteListItem(UrlWhiteListDto urlWhiteListDto) throws Exception {
    String domainUrlToBeAdded = parseUrl(urlWhiteListDto.getDomain());
    if (isDomainExistbyName(domainUrlToBeAdded)) {
        throw new Exception("Already existed domain is tried to be added");
    }
    UrlWhitelist urlModel = mapper.map(urlWhiteListDto,UrlWhitelist.class);
    urlDao.store(urlModel);
    return urlWhiteListDto;

}

我的模型类是:

@Entity
@Table(name = UrlWhitelist.TABLE_NAME)
public class UrlWhitelist implements EntityBean { 

    public static final String TABLE_NAME = "URL_WHITE_LIST";

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "ID", nullable = false)
    private Long id;

    @NotBlank
    @Column(name = "DOMAIN", nullable = false)
    private String domain;

    @NotBlank
    @Column(name = "DISABLE", nullable = false)
    private boolean disabled;

    // getters & setters omitted
}

而DAO实现类是:

public class UrlWhiteListDaoImpl extends EntityDaoImpl<UrlWhitelist, Long> implements UrlWhiteListDao {

    protected UrlWhiteListDaoImpl() {
        super(UrlWhitelist.class);
    }

    @Override
    public List<UrlWhitelist> getByDomainName(String name) {
        DetachedCriteria criteria = DetachedCriteria.forClass(UrlWhitelist.class);
        criteria.add(Restrictions.eq("domain", name));
        return getAllByCriteria(criteria);
    }
}

在控制台中没有错误,但在服务器日志中它说:

严重:servlet [服务] 的 Servlet.service() 在路径 [] 的上下文中引发异常 [请求处理失败;嵌套异常是 javax.validation.UnexpectedTypeException: HV000030: 找不到约束“org.hibernate.validator.constraints.NotBlank”验证类型“java.lang.Boolean”的验证器。检查“禁用”的配置,根本原因是 javax.validation.UnexpectedTypeException: HV000030: 找不到约束“org.hibernate.validator.constraints.NotBlank”验证类型“java.lang.Boolean”的验证器。检查“禁用”的配置

我认为 to 和模型类之间的映射有问题,但是,为什么 get 方法有效而只是store()无效?解决办法是什么 ?

您应该使用@NotNull注释。

boolean是原始类型,而不是对象类型 ( Boolean) 因此@NotNull无法应用约束,因为原始类型不能是null。注释执行以下验证(格式由我添加):

带注释的元素不能是null。接受任何类型。

使用对象类型:

@NotNull
@Column(name = "DISABLE", nullable = false)
private Boolean disabled;
