使用JPA注解配置映射关系

package com.cedric.domain;
import javax.persistence.*;
/**
 * 1.实体类和表的映射关系
 *      @Entity
 *      @Table
 * 2.类中属性和表中字段的映射关系
 *      @Id
 *      @GeneratedValue
 *      @Column
 */
@Entity
@Table(name = "cst_customer")
public class Customer {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "cust_id")
    private Long custId;
    @Column(name = "cust_address")
    private String custAddress;
    @Column(name = "cust_industry")
    private String custIndustry;
    @Column(name = "cust_level")
    private String custLevel;
    @Column(name = "cust_name")
    private String custName;
    @Column(name = "cust_phone")
    private String custPhone;
    @Column(name = "cust_source")
    private String custSource;
    // set and get
    // toString
