Question

使用Spring Boot Parent 2.1.0的单元测试。将更新应用于Game对象内的List对象后，我需要测试值的更新。我读了另一个线程以添加以下语句，但在我的情况下无法使用

     @Modifying(clearAutomatically = true)

Game.java

@Data
@Entity
public class Game {

         @Id

         private Integer id;
         @ElementCollection
         @Column(name = "pits")
         private List<Integer> boardList;
         private Status status;
         private String message;

         public Game() {
         }

         public Game(String message) {
                  this.boardList = Arrays.asList(new Integer[]{6, 6, 6, 6, 6, 6, 0, 6, 6, 6, 6, 6, 6, 0});
                  this.status = Status.PLAYER1TURN;
                  this.message = message;

}

GameRepository.java

import com.game.kalah.domain.Game;
import org.springframework.data.repository.CrudRepository;

/**
 *
 * @author Nesrin
 */
public interface GameRepository extends CrudRepository<Game, Integer> {
}

错误如下，它是在测试类中第二次调用save的行上

 Game afterFirstMove = repository.save(savedGame);

test_save_game（com.game.kalah.repository.GameRepositoryTest）时间经过：0.106 s <<<错误！ java.lang.UnsupportedOperationException 在 com.game.kalah.repository.GameRepositoryTest.test_save_game（GameRepositoryTest.java:85）

pom.xml父部分

您尝试使用可变列表吗？ Arrays.asList(array)创建一个不可变的列表。

尝试使用new ArrayList<>(Arrays.asList(array))。检查此link

此外，如果您发布整个错误日志，也会很有帮助。

使用DataJpaTest Spring Boot 2.1.0更新失败
