從數據庫中獲取枚舉值時出錯：沒有枚舉常量，嵌套異常是 java.lang.IllegalArgumentException
[英]Error while fetching enum value from database: No enum constant, nested exception is java.lang.IllegalArgumentException
問題描述
我試圖構建一個示例應用程序，用戶可以在其中添加帖子，其他人可以對其投贊成票或反對票。 我將 Vote 作為一個實體 class 來保存用戶是否贊成或反對的數據。 贊成票和反對票表示為枚舉。 當我試圖通過帖子 ID 和用戶 ID 獲取所有投票時，我收到一個錯誤，因為No enum constant com.sachinmukherjee.model.VoteType.up; nested exception is java.lang.IllegalArgumentException: at java.lang.Enum.valueOf() No enum constant com.sachinmukherjee.model.VoteType.up; nested exception is java.lang.IllegalArgumentException: at java.lang.Enum.valueOf()
我的投票 Class (Vote.java)看起來像這樣
package com.sachinmukherjee.model;
@Data
@NoArgsConstructor
@AllArgsConstructor
@Entity
public class Vote {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private long id;
@Enumerated(EnumType.STRING)
@Column(length = 4)
private VoteType voteType;
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "post_id", referencedColumnName = "id")
private Post post;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "user_id", referencedColumnName = "id")
private User user;
}
我的 VoteType (VoteType.java)枚舉 class 看起來像這樣
package com.sachinmukherjee.model;
public enum VoteType {
UPVOTE("up"), DOWNVOTE("down"),;
private String direction;
VoteType(String direction) {
this.direction = direction;
}
public String getDirection() {
return direction;
}
public static VoteType getVoteType(String direction) {
switch (direction) {
case "up":
return VoteType.valueOf(direction);
case "down":
return VoteType.valueOf(direction);
default:
throw new IllegalArgumentException("Illegal Vote");
}
}
}
我的 VoteRepository (VoteRepository.java) class 看起來像這樣
@Repository
public interface VoteRepository extends JpaRepository<Vote, Long> {
List<Vote> findByPostAndUser(Post post,User user);
}
我的投票服務(VoteService.java) class 看起來像這樣
@Service
@Transactional
public class VoteService {
@Autowired
private VoteRepository voteRepository;
@Autowired
private PostRepository postRepository;
@Autowired
private AuthService authService;
public void vote(VoteDto voteDto) {
User user = authService.getCurrentUser();
Post post = postRepository.findById(Long.valueOf(voteDto.getPostId()));
try {
List<Vote> vote = voteRepository.findByPostAndUser(post, user);
}catch (Exception e) {
e.printStackTrace();
}
}
}
我的投票表的數據庫表結構如下所示
+-----------+------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-----------+------------+------+-----+---------+----------------+
| id | bigint(20) | NO | PRI | NULL | auto_increment |
| vote_type | varchar(4) | YES | | NULL | |
| post_id | bigint(20) | YES | MUL | NULL | |
| user_id | bigint(20) | YES | MUL | NULL | |

當您創建枚舉時，枚舉名稱（ UPVOTE ("up"), DOWNVOTE ("down")) 進入數據庫，確保它在表中的大寫字母中。 該值僅在服務級別，我建議，除非需要，否則避免添加值字符串。
試試這個版本的 getVoteType
public static VoteType getVoteType(final String value) {
for (final VoteType voteType : values()) {
if (voteType.value.equalsIgnoreCase(value)) {
return voteType;
}
}
final String message = "Unknown VoteType " + value + ", allowed values are " + Arrays.toString(values());
throw new Excetion(message);
}
解決方案2
1 已采納 2020-06-28 08:30:29
您應該將UPVOTE或DOWNVOTE作為數據庫中的值。 因為 JPA 會尋找同名的枚舉。
如果您已經將該值存儲在 db 中，請刪除它並通過您的應用程序重新創建它。
