Spring boot H2数据库的data.sql脚本在我的应用程序为SpringBoot运行后执行

我假设H2数据库的data.sql脚本是在应用程序运行后执行的，因此findById（）（CRUD方法）不会获取任何数据（NULL）。我怎样才能解决这个问题

请查找我的日志详细信息：

更新： 请找到我的data.sql

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

@组成部分 公共类示例DAO{

@Autowired
ExampleRepository exampleRepository;

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

//添加了getters setters和constructor

您需要提供data.sql和有关如何调用findById（）方法的代码。请在上面的帖子中查找更新，然后检查启动后数据是否已插入数据库？您可以使用h2-console进行检查。这就是问题所在，在程序执行之前没有插入data.sql。它只在程序执行后才执行。因此，我的h2数据库仍然是空的，并且我无法从数据库中获取任何内容，因为在对数据库进行findBy（）调用时，它是空的。我在程序运行期间进行的任何save（）调用都将被执行。意思是说它能够访问数据库。data.sql只有在程序运行后才会初始化。我还想知道为什么h2中的实体和java中的我的实体的参数顺序会发生变化，以及如何克服这个问题？我已经使用@PostConstruct调用了我的服务类方法。这就是问题所在吗？如果是这样的话，那么在应用程序启动时，在没有控制器的情况下，什么样的替换注释可以开始触发我的服务层中的方法呢？

ArrayList<Example> findByVar(String Var);

@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;
