java - junit 测试中的 spring-data-jpa bean 验证

在我最近的工作中，我使用 spring-data-jpa 来利用提供的存储库。当涉及到集成测试时，我无法配置(我假设)用于测试的 spring 上下文，因此 bean 验证在我的测试中不起作用。

我知道我可以注入(inject) validator ，并对我的注释进行单元测试，但事实并非如此。我正在编写集成测试，并希望测试有数据库支持的存储库。

我准备了一个简单的项目来展示所有必要的项目文件。

当我运行测试时，有 2 个失败了，我不知道为什么，hibernate validator 出现在类路径上。

Failed tests:   insertWrongEmail(com.example.core.data.jpa.UserRepositoryTest): Expected ConstraintViolationException wasn't thrown.
insertToShortPassword(com.example.core.data.jpa.UserRepositoryTest): Expected ConstraintViolationException wasn't thrown.

[..]

INFO: HV000001: Hibernate Validator 4.3.1.Final

源代码和 mvn 测试 下面的输出。

预先感谢您的帮助。

Java 类(我去掉了注释、geters、seters、equals、hashCode、toString 等):

基础实体

package com.example.core.data.jpa;

import javax.persistence.*;

@MappedSuperclass
public abstract class BaseEntity {
    public static final String SEQUENCE = "global_seq";

    @Id
    @SequenceGenerator(name = SEQUENCE, sequenceName = SEQUENCE)
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = SEQUENCE)
    @Column(name = "id")
    private Long id;

    public Long getId() {
        return id;
    }
}

用户

package com.example.core.data.jpa;

import javax.persistence.*;
import javax.validation.constraints.Pattern;
import java.io.Serializable;
import java.util.List;

@Entity
@Table(name = "users")
@NamedQuery(name = "User.findByEmail", query = "select u from User u where upper(u.email) = :email")
public class User extends BaseEntity implements Serializable {
    private static final long serialVersionUID = 333700989750828624L;

    private static final int MAX_NAME_LENGTH = 128;
    private static final int MAX_EMAIL_LENGTH = 128;
    private static final int MAX_PASSWORD_LENGTH = 256;
    private static final int MIN_NAME_LENGTH = 6;

    private static final int EQUALS_MAGIC = 71;

    @Size(min = MIN_NAME_LENGTH)    
    @Column(name = "name", nullable = false, length = MAX_NAME_LENGTH)
    private String name;

    @Pattern(regexp = "^([0-9a-zA-Z]([-.\\w]*[0-9a-zA-Z])*@([0-9a-zA-Z][-\\w]*[0-9a-zA-Z]\\.)+[a-zA-Z]{2,9})$")
    @Column(name = "email", nullable = false, unique = true, length = MAX_EMAIL_LENGTH)
    private String email;

    @Column(name = "password", nullable = false, length = MAX_PASSWORD_LENGTH)
    private String password;

    @OneToMany(mappedBy="user", cascade={CascadeType.ALL}, fetch = FetchType.EAGER)
    private List<Role> roles;
//geters, seters, equals, hashCode
}

作用

package com.example.core.data.jpa;

import javax.persistence.*;
import java.io.Serializable;

@Entity
@Table(name = "roles")
public class Role extends BaseEntity implements Serializable {
    private static final long serialVersionUID = -2575871700366265974L;

    private static final int MAX_NAME_LENGTH = 128;

    @Column(name = "name", nullable = false, unique = true, length = MAX_NAME_LENGTH)
    private String name;

    @ManyToOne(cascade={CascadeType.ALL})
    private User user;
//geters, seters, equals, hashCode
}

已解决

在@gunnar 回答后，我更改了测试以在 repository.save 之后刷新持久性上下文，它按预期工作。

对 UserRepository 的更改

//inject entity manager
@PersistenceContext
private EntityManager entityManager;

//add flush after save in test method
@Test
public void insertWrongEmail() {
    //given
    user.setEmail("NOT_AN_EMAIL_ADDRESS");

    //when
    try {
        userRepository.save(user);
        entityManager.flush();

        fail("Expected ConstraintViolationException wasn't thrown.");

方案二

在@andyb 的推荐下，我已经切换到 eclipselink 并且测试工作无需刷新。这就是我将采用的解决方案，我认为切换实现比使用变通方法更好。

最佳答案

我设法在本地重现问题中准确描述的问题，尽管是在添加回缺少的 get/set 函数和 UserRepository 类之后:-)

经过一番挖掘，我发现了两个存在的问题 JPA ConstraintViolation vs Rollback和 Hibernate not following JPA specifications when combined with Bean Validation API?

两者似乎都得出结论，Hibernate 没有正确抛出 ConstraintValidationException。

第二题的结果是缺陷HHH-8028 - entityManager.persist not throwing ConstraintValidationException针对 Hibernate 提出。

为了确认这是同一个问题，我切换到一个简单的 @GeneratedValue 并通过了 insertWrongEmail。 insertToShortPassword 仍然失败，但我将其归因于密码字段中缺少的 @Size(min = 6)。添加之后，所有测试都通过了。

回到您配置的 @GeneratedValue 然后我将 Hibernate 换成 EclipseLink 持久性框架。两项测试都通过了，这似乎证实了前面问题的发现。我所做的更改是:

pom.xml 更改添加了 jpa 工件，如 EclipseLink 中所述网站

<dependency>
   <groupId>org.eclipse.persistence</groupId>
   <artifactId>org.eclipse.persistence.jpa</artifactId>
   <version>2.4.0</version>
   <scope>compile</scope>
</dependency>

test-context.xml 更改

切换到EclipseLinkJpaVendorAdapter

<bean id="jpaAdapter" class="org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter"
    p:generateDdl="true" p:database="HSQL" />

添加 eclipselink.weaving 属性，详见 EclipseLinkJpaVendorAdapter instead of HibernateJpaVendorAdapter issue 

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
    p:dataSource-ref="dataSource" p:jpaVendorAdapter-ref="jpaAdapter" >
    <!-- existing configuration is identical -->
    <property name="jpaPropertyMap">
      <map>
        <entry key="eclipselink.weaving" value="false"/>
      </map>
    </property>
</bean>

User.java 变化

我需要添加一个默认的无参数构造函数。您可能已经在完整的 User.java 类中拥有一个。

关于java - junit 测试中的 spring-data-jpa bean 验证，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/16172843/
