在Spring Data JPA中查询枚举列表字段的Crud方法

时间：2016-01-18 14:07:02

标签： spring jpa enums spring-data-jpa crud

我有一个用户个人资料类，其中包含一个字段，该字段是枚举角色的列表：

enum UserRole {
    USER,
    ADMIN;

    public static final int MAX_LENGTH = 5;
}

@Entity
@Table(name = "UserProfiles")
class UserProfile {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int id;
    ...
    @ElementCollection(fetch = FetchType.EAGER)
    @CollectionTable(name = "UserRoles", joinColumns = @JoinColumn(name = "id"))
    @Column(name = "Role", length = UserRole.MAX_LENGTH, nullable = false)
    @Enumerated(EnumType.STRING)
    private List<UserRole> roles;
    ...
}

如您所见，为了便于阅读，用户角色存储为字符串＆＃34; USER＆＃34;和＆＃34; ADMIN＆＃34;在数据库中。请注意，用户可能有多个角色，即USER和ADMIN，因此roles字段是枚举列表。

在用户个人资料Crud中，我尝试构建一个返回常规用户或管理员列表的查询方法：

@Repository
public interface UserProfileCrud extends CrudRepository<UserProfile, Integer> {
    ...
    Iterable<UserProfile> findByRolesContains(UserRole userRole);
}

但是，findByRolesContains(UserRole.ADMIN)失败并出现以下异常：

Parameter value [%ADMIN%] did not match expected type [domain.UserRole (n/a)]; nested exception is java.lang.IllegalArgumentException: Parameter value [%ADMIN%] did not match expected type [domain.UserRole (n/a)]

日志中的查询：

Hibernate: select userprofil0_.id as id1_10_,
 userprofil0_.create_timestamp as create_t8_10_,
 userprofil0_.first_name as first_na9_10_,
 userprofil0_.last_login as last_lo11_10_,
 userprofil0_.last_name as last_na12_10_,
 userprofil0_.password as passwor13_10_,
 userprofil0_.role_names as role_na14_10_,
 userprofil0_.state as state15_10_,
 userprofil0_.update_timestamp as update_16_10_,
 userprofil0_.username as usernam17_10_
from user_profiles userprofil0_ where userprofil0_.username=?

Hibernate: select roles0_.id as id1_10_0_,
 roles0_.role as role2_11_0_
from user_roles roles0_ where roles0_.id=?

堆栈追踪：

是否可以重新定义Crud方法以正常工作，而无需在@Query中构建显式SQL查询？

2 个答案:

答案 0 :(得分：0)

您的方法应定义如下。我没有测试它，所以让我知道结果是否正确。

@Repository
public interface UserProfileCrud extends CrudRepository<UserProfile, Integer> {
    ...
    Iterable<UserProfile> findByRolesIn(List<UserRole> userRoles);
}

答案 1 :(得分：0)

这对我有用（Spring Boot 5.0）

回购：

public interface UserRepository extends CrudRepository<User, Integer> {

    User findByUsername(String username);

    List<User> findAllByRolesIn(Set<Role> role);
}

我的pojo：

@Entity
@Table(name = "usr") // PostgreSQL not work with table "user"
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int id;
    @NotNull
    private String username;
    @NotNull
    private String password;
    @NotNull
    private boolean active;
    @NotNull
    @ElementCollection(targetClass = Role.class, fetch = FetchType.EAGER)
    @Column(name = "role", nullable = false)
    @CollectionTable(name = "user_roles", joinColumns = @JoinColumn(name = "user_id"))
    @Enumerated(EnumType.STRING)
    private Set<Role> roles;

和Role.class：

public enum Role {
    ADMIN, MODERATOR, USER;
}
