我的应用程序为SpringBoot运行后，正在执行H2数据库的data.sql脚本

问题描述

我假设我的应用程序运行后，我的H2数据库的data.sql脚本正在执行，因此，findById（）（CRUD方法）没有获取任何数据（NULL）。我该如何解决？

请找到我的日志详细信息：

更新：请找到我的data.sql

插入示例值（默认值，'a'，'b'，'c'，'d'，'e'，'f'，1,2，'y'）；插入示例值（默认，'g'，'h'，'i'，'j'，'k'，'l'，2,3，'n'）; 这是木刀课

@Component 公共类ExampleDao {

@Autowired
ExampleRepository exampleRepository;

public ArrayList<Example> dbFetchDetails(String var)
{
    ArrayList<Example> exampleList = new ArrayList<>();
    exampleList= exampleRepository.findByVar(var);
   return exampleList;
    }}

我使用CRUDREPOSITORY扩展我的仓库，并定义findByVar（）

@存储库公共接口ExampleRepository扩展了CrudRepository {

ArrayList<Example> findByVar(String Var);

}

@实体公共类示例{

@Id @GeneratedValue(strategy= GenerationType.IDENTITY)
private Integer id;
private String a;
private String b;
private String c;
private String d;
private int e;
private int f;
private String g;
private String h;
private Character i;

//添加了getters的setter和contructor }
