与JSF一起使用 - HIbernate验证失败(javax.validation.ConstraintViolationException)

我正在使用JSF,Spring和Hibernate。 Post模型具有Hibernate注释属性:

@Entity
@Table(name = "posts")
public class Post implements Serializable {

    @Id
    @GeneratedValue(strategy = IDENTITY)
    @Column(name = "id")
    private Long id;

    private int version;

    @Column(name = "title")
    @NotEmpty(message = "Title should not be empty")
    private String title;

    ... getters/setters

}

当我尝试在相应的bean中创建一个新帖子时(忽略语法正确的à漂亮面孔):

@Component
@ManagedBean
@RequestScoped
@URLMappings(mappings = {
        @URLMapping(id = "posts", pattern = "/posts/", viewId = "/faces/posts/list.xhtml"),
        @URLMapping(id = "new", pattern = "/posts/new", viewId = "/faces/posts/new.xhtml")
})
public class PostBean {

    @Autowired
    private PostService postService;

    private List<Post> posts;

    private Post post = new Post();

    public List<Post> getPosts() {
        return postService.findAll();
    }

    public Post getPost() {
        return post;
    }

    public void setPost(Post post) {
        this.post = post;
    }

    public String create(Post post) {
        this.post = postService.save(post);
        return "pretty:posts";
    }
}

PostRepository:

public interface PostRepository extends CrudRepository<Post, Long> {
    public Post findByTitleIgnoreCase(String title);
}

PostServiceImpl:

@Service("postService")
@Repository
@Transactional
public class PostServiceImpl implements PostService {

    @Autowired
    private PostRepository postRepository;

    @Override
    @Transactional(readOnly = true)
    public List<Post> findAll() {
        return Lists.newArrayList(postRepository.findAll());
    }

    @Override
    @Transactional(readOnly = true)
    public Post findById(Long id) {
        return postRepository.findOne(id);
    }

    @Override
    @Transactional(readOnly = true)
    public Post findByTitleIgnoreCase(String title) {
        return postRepository.findByTitleIgnoreCase(title);
    }


    @Override
    @Transactional
    public Post save(Post post) {
        return postRepository.save(post);
    }

    @Override
    public void destroy(Post post) {
        postRepository.delete(post);
    }
}

我得到javax.validation.ConstraintViolationException。奇怪的是,如果删除Hibernate注释并将required="true"直接放到标题文本字段旁边的JSF页面中,它就可以工作。

<h:inputText id="title" value="#{postBean.post.title}" required="true"/>

有什么想法吗?您可以在my github repo找到项目代码来源 谢谢。

@NotNull是一个JSR303验证,@ NotEmpty - 是Hibernate的一个,这是唯一的区别。即使在更改了@NotNull后,我仍然会遇到同样的错误。

[update]顺便说一句,我删除了@ManagedBean注释,不再需要它了。 [update-2] @AVolpe:它不会改变任何内容,只需将消息移动到标题文本字段旁边即可。调用时发生错误:

public String create(Post post) {
        this.post = postService.save(post);
        return "pretty:posts";
    }

由于2.2.6 JSF的版本BeanValidation不能与2.2.7配合使用,因此请更新至版本2.2.4或降级至{{ 1}}。

通过按照AVolpe的建议升级jsf版本2.2.7进行修复。
