1-2SPRING-BOOT-JPA添加lombok-管理getter/setter

1.1  lombok 详细使用可以看官网:https://projectlombok.org/features/all

1.2  使用@Data注解，这个注解的作用是：

@Data

All together now: A shortcut for @ToString, @EqualsAndHashCode, @Getter on all fields, and @Setter on all non-final fields, and @RequiredArgsConstructor!

1.3 修改我们的domain.Company代码如下：这里已经不必谢getter/setter方法

package com.leilei.springbootcrm.domain;

import lombok.Data;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import java.io.Serializable;
import java.util.Date;

@Entity
@Data
public class Company implements Serializable {
    private static final long serialVersionUID = 7471779949543151367L;

    @GeneratedValue
    @Id
    private Integer id;

    @Column(length = 50, nullable = false)
    private String CompanyName;

    private Date createTime;

}

1.4 在上一篇 CompanyDaoTest追加一个测试用例，

    @Test
    void testFindAll() {
        List<Company> companyList = companyDao.findAll();
        System.out.println(companyList);
    }

1.5查看控制台打印，发现我们的toString()方法已经被重写
