java - org.springframework.core.convert.ConverterNotFoundException : No converter found capable of converting from type Account to type AllAccount

Question

我正在使用SpringBoot和JPA来调用db，我遇到异常

org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [com.xxx.central.model.Account] to type [com.xxx.central.model.AllAccount]

下面是我的代码

Account.java

@Entity
@Table(name = "account")
public class Account implements Serializable {

AllAccount.java

@Entity(name="allAccounts")
@Table(name = "account")
public class AllAccount implements Serializable {

AccountRepository.java

@RepositoryDefinition(domainClass = Account.class, idClass = Integer.class)
public interface AccountRepository extends CrudRepository<Account, Integer> 
{

public List<AllAccount> 
findByIsActiveAndClientNameIgnoreCaseContainingOrderByAccountCreatedDesc(
        Boolean active, String clientNameSearchString);
}

当我从我的服务类调用上面的存储库时，我收到异常。我哪里出错了？谢谢。

Answer 1

public interface AccountRepository extends CrudRepository<Account, Integer> 

此行使您的 Repository 类仅返回对象 Account 类型。

这就是为什么当你打电话时

public List<AllAccount> 
findByIsActiveAndClientNameIgnoreCaseContainingOrderByAccountCreatedDesc

它尝试从类型 Account 转换为 AllAccount 但它不能，因此出现异常。

您可以为 AllAccount 创建一个不同的存储库类，或者通过更改为

来更改此存储库类以返回 AllAccount

public interface AccountRepository extends CrudRepository<AllAccount, Integer>
