在Spring Boot MyBatisPlus中自定义SQL语句可以通过使用@SelectProvider注解来实现。以下是一个简单的示例:
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();
}
通过以上步骤,您可以在Spring Boot MyBatisPlus中自定义SQL语句并进行使用。您也可以根据实际的需求来扩展和修改自定义SQL语句的生成逻辑。
