（2）创建实体类
```java
@Entity
public class EmotionCategory {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String name;
}
@Entity
public class Emotion {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String name;
private Long categoryId;
private String imageUrl;
}
```
（3）创建Repository接口
```java
public interface EmotionRepository extends JpaRepository {
List findByNameContaining(String name);
}
```
（4）创建Service接口和实现类
```java
public interface EmotionService {
List searchEmotions(String name);
}
@Service
public class EmotionServiceImpl implements EmotionService {
@Autowired
private EmotionRepository emotionRepository;
@Override
public List searchEmotions(String name) {
return emotionRepository.findByNameContaining(name);
}
}
```
（5）创建Controller类
```java
@RestController
@RequestMapping("/emotions")
public class EmotionController {
@Autowired
private EmotionService emotionService;
@GetMapping("/search")
public ResponseEntity
