所以我查看了有关使用Spring Data的JPA的各种教程,这在很多场合都有所不同,我不太确定正确的方法是什么.

假设有以下实体:

package stackoverflowTest.dao;

import javax.persistence.*;

@Entity
@Table(name = "customers")
public class Customer {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "id")
private long id;

@Column(name = "name")
private String name;

public Customer(String name) {
    this.name = name;
}

public Customer() {
}

public long getId() {
    return id;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}
}

我们还有一个DTO,它在服务层中检索,然后交给控制器/客户端.

package stackoverflowTest.dto;

public class CustomerDto {

private long id;
private String name; …
