Java Can';t使用SpringDataCouchbase将JSON对象从Couchbase映射到DTO实体_Java_Spring_Couchbase_Spring Data Couchbase - Fatal编程技术网

Java Can';t使用SpringDataCouchbase将JSON对象从Couchbase映射到DTO实体

Java Can';t使用SpringDataCouchbase将JSON对象从Couchbase映射到DTO实体,java,spring,couchbase,spring-data-couchbase,Java,Spring,Couchbase,Spring Data Couchbase,我已经创建了一些数据模型对象来插入Couchbase并从中读取。它有简单的类型,2个字段是其他DTO对象 @Data @AllArgsConstructor @Document public class Customer { @Id private int id; private String fullName; private String phoneNumber; private String address; private Dat

我已经创建了一些数据模型对象来插入Couchbase并从中读取。它有简单的类型,2个字段是其他DTO对象

@Data
@AllArgsConstructor
@Document
public class Customer {

    @Id
    private int id;

    private String fullName;

    private String phoneNumber;

    private String address;

    private Date registrationDate;

    private boolean isBusiness;

    private String status;

    private Tariff currentTariff;

    private BillingAccount billingAccount;
}
所以,我用逻辑创建了10000个随机客户对象,然后它创建repository.saveAll(customers)

我可以在Couchbase UI中看到这些数据

但是,我想从Couchbase获取所有这些客户对象。这是我的密码

    @GetMapping("/findAllCustomers")
    public Iterable<Customer> getAll() {
        return repository.findAll();
    }
@GetMapping(“/findAllCustomers”)
公共Iterable getAll(){
返回repository.findAll();
}
非常简单,没有自定义转换,没有其他复杂的东西。我期望的类型正是我生成和保存此数据时使用的类型

我得到以下错误:

未能使用实例化com.bamber.boostr.model.Customer constructor public com.bacher.boostr.model.Customer

原因:java.lang.ClassCastException:java.lang.String不能为 转换为java.lang.Integer\r\n\t com.bacher.boostr.model.Customer_实例化器_z47nsm.newInstance(未知 源)\r\n\t org.springframework.data.convert.ClassGeneratingTityInstantiator$EntityInstantiatorAdapter.createInstance(ClassGeneratingTityInstantiator.java:226)\r\n\t


请帮助

我删除了@AllArgsConstructor Lombok注释,并创建了没有Id字段的构造函数

@Data
@Document
public class Customer {

    @Id
    @GeneratedValue(strategy = GenerationStrategy.UNIQUE)
    private String id;

    private String fullName;

    private String phoneNumber;

    private String address;

    private Date registrationDate;

    private boolean isBusiness;

    private String status;

    private Tariff currentTariff;

    private BillingAccount billingAccount;

    public Customer(String fullName, String phoneNumber, String address, Date registrationDate, boolean isBusiness, String status, Tariff currentTariff, BillingAccount billingAccount) {
        this.fullName = fullName;
        this.phoneNumber = phoneNumber;
        this.address = address;
        this.registrationDate = registrationDate;
        this.isBusiness = isBusiness;
        this.status = status;
        this.currentTariff = currentTariff;
        this.billingAccount = billingAccount;
    }
}
在那之后,它工作得很好。读和写操作
