Bean验证不起作用？

Question

我有一个services 模块，ClientRequest 类为

public class ClientRequest {
    @NotNull(message = "email can not be empty")
    private String email;
    @NotNull(message = "userExternalId can not be empty")
    private String userExternalId;
    @NotNull(message = "password can not be empty")
    private String password;


    @SuppressWarnings("UnusedDeclaration")
    public ClientRequest() {
        // used by jax-rs
    }

services/pom.xml有

<properties>
    <validation-api.version>1.1.0.Final</validation-api.version>
</properties>

<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>${validation-api.version}</version>
</dependency>

我有 integration 用于编写集成测试的模块。
integration/pom.xml 看起来像

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>4.0.2.GA</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>${slf4j-api.version}</version>
    <scope>test</scope>
</dependency>  

我的测试看起来像

    @Test
    public void testRegisterClientInValid() throws IOException {
        final Client client = ClientBuilder.newClient();
        final Invocation.Builder request = client.target("http://localhost:9090/application/oauth/register").request(MediaType.APPLICATION_JSON);
        final Map<String, String> parameters = new HashMap<>();
        parameters.put("email", "integrationTest@gmail.com");
        final Response response = request.post(Entity.entity(parameters, MediaType.APPLICATION_JSON));
        assertEquals(HttpStatus.SC_OK, response.getStatus());

        final JsonNode jsonReply = getObjectMapper().readTree(response.readEntity(String.class));
        System.out.println(jsonReply);
    }  

由于我预计它会因bean validation 而失败，所以我看到了日志要说的内容。

我明白了

这意味着 bean validation 已通过，错误在数据库层，因为数据库需要 not null 值

问题
为什么bean验证不起作用，我在这里做错了什么？

Answer 1

根据您的示例，您正在使用 Hibernate Validator 4.0.2.GA 和 Bean Validation 1.1.0.Final。那是行不通的。要使用 Bean Validation 1.1，您需要 Hibernate Validator 5.x（5.1.2.Final 是最新的）。我希望您的示例甚至没有正确引导或至少吃日志中有一些警告。
