这样就完成了工程的配置了！！！
二、简单业务逻辑测试框架
简单的bean：（为了偷懒就用JPA自动建表了，不过后面会给出sql，而且JPA自动建表有坑！！）
//积分变化记录
@Entity
@Table(name = "i_dou_change")
public class IDouChange {
private Long id;
//积分变化的类型，拉黑或者在线或者充值
private String changeType;
private Date createTime;
//积分变化数
private Integer iDouCount;
//积分变化者
private User user;
public IDouChange() {
}
@Id
@GeneratedValue
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
@Column(name = "change_type")
public String getChangeType() {
return changeType;
}
public void setChangeType(String changeType) {
this.changeType = changeType;
}
@Temporal(TemporalType.TIMESTAMP)
@Column(name = "create_time",nullable=true,columnDefinition="timestamp default current_timestamp")
public Date getCreateTime() {
return createTime;
}
public void setCreateTime(Date createTime) {
this.createTime = createTime;
}
@Column(name = "i_dou_count")
public Integer getiDouCount() {
return iDouCount;
}
public void setiDouCount(Integer iDouCount) {
this.iDouCount = iDouCount;
}
//简单的多对一
@JoinColumn(name="user_id")
@ManyToOne(fetch= FetchType.LAZY)
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}
对应的repository接口dao
@Repository
public interface AiDouChangeRepository extends JpaRepository {
}
对应的service
@Service
public class AiDouService {
@Autowired
private AiDouChangeRepository aiDouChangeRepository;
public void save(IDouChange iDouChange){
aiDouChangeRepository.save(iDouChange);
}
}
