在Spring Boot MyBatisPlus中自定義SQL語句可以通過使用@SelectProvider注解來實現。以下是一個簡單的示例:
public interface CustomSQLMapper {
@SelectProvider(type = CustomSQLProvider.class, method = "getCustomSQL")
List<MyEntity> getCustomSQL();
}
public class CustomSQLProvider {
public String getCustomSQL() {
return "SELECT * FROM my_table WHERE column = 'value'";
}
}
@Mapper
public interface MyMapper extends BaseMapper<MyEntity>, CustomSQLMapper {
// other methods here
}
@Autowired
private CustomSQLMapper customSQLMapper;
public List<MyEntity> getCustomData() {
return customSQLMapper.getCustomSQL();
}
通過以上步驟,您可以在Spring Boot MyBatisPlus中自定義SQL語句并進行使用。您也可以根據實際的需求來擴展和修改自定義SQL語句的生成邏輯。
