异常信息意思还是很容易懂的，就是提供的Id的类错误
报错的代码如下：
CDCCommonFriends dto =cdcCommonFriendsRepository.findOne(phone);//此处的phone 是Long类型的
这个findOne方法是JPA底层提供的。
而我的CDCCommonFriendsRepository类是这么定义的
public interface CDCCommonFriendsRepository extends CrudRepository<CDCCommonFriends,Long> {
}
CrudRepository这个接口泛型的第一个参数是对应的类，第二个参数是该类的ID
但我的CDCCommonFriends类定义了联合主键：
@Data
@Entity
@Table(name="××××")
@IdClass(value=CDCCommonFriendsID.class)
public class CDCCommonFriends {
@Id
private Long phone;
private String cfs_cnt;
@Id
private String source;
private Date created_date; }
所以CDCCommonFriendsRepository类定义时传入的Id错了。
修改代码如下：
public interface CDCCommonFriendsRepository extends CrudRepository<CDCCommonFriends,CDCCommonFriendsID> {
}
修改调用时出入的参数：
CDCCommonFriendsID id = new CDCCommonFriendsID();
id.setPhone(commonFriends.getPhone());
id.setSource(commonFriends.getSource());
dto =cdcCommonFriendsRepository.findOne(id);
问题解决！！！
