jhipster入門疑問之路之五

由於項目需求，需要將以往寫的jpa的數據增刪改查操作換成mybatis，所以稍作了解mybatis

因時間緊迫，並沒有對深入實現原理進行學習，只是查詢相關資料，學習如何使用。在本項目中，因已經有前輩所在準備，故配置之類並未進行修改。

mybatis與spring cloud 結合使用

1 首先是定義domain。如果相關聯查詢，需要在domain中包含索要關聯查詢的domain屬性

    private static final long serialVersionUID = -1654620673909327705L;
    private String userId;
    private String loginCode;
    private String userName;
    private String certType;
    private String certNo;
    private String userCode;
    private String deadline;
    private String orgId;
    private String dptId;
    private String userPassword;
    private String userSex;
    private String userBirthday;
    private String userEmail;
    private String userMobilephone;
    private String userOfficetel;
    private String userEducation;
    private String userCertificate;
    private String entrantsDate;
    private String positionTime;
    private String financialJobTime;
    private String positionDegree;
    private String userAvatar;
    private String offenIp;
    private String userSts = "1";
    private String lastLoginTime;
    private String lastEditPassTime;
    private String lastChgUsr = SecurityUtils.getCurrentUserLogin();
    private String lastChgDt = DateFormatUtils.format(new Date(), "yyyy-MM-dd HH:mm:ss");
    //private AdminSmDpt adminSmDpt;
    private Set<AdminSmRole> authorities = new HashSet<>();
   // private AdminSmOrg adminSmOrg;
    //private AdminSmInstu adminSmInstu;

代碼中的

Set<AdminSmRole> authorities

是AdminSmUser 這個domain的一個屬性，當然也需要建立該domain

public class AdminSmRole implements Serializable{
    private static final long serialVersionUID = -3798852960056031116L;
    private String roleId;
    private String roleCode;
    private String roleName;
    private String orgId;
    private String roleLevel;
    private String roleSts;
    private String lastChgUsr = SecurityUtils.getCurrentUserLogin();
    private String lastChgDt = DateFormatUtils.format(new Date(), "yyyy-MM-dd HH:mm:ss");

2建立AdminSmUserMapper.jave

public interface AdminSmUserMapper {

	public AdminSmUser selectAdminSmUser(@Param("loginCode") String loginCode);
	//public AdminSmUser selectAdminSmUserWithDpt(@Param("loginCode") String loginCode);
	public AdminSmUser selectAdminSmUserWithRoles(@Param("loginCode") String loginCode);
	public AdminSmUser selectAdminSmUserWithAll(@Param("loginCode") String loginCode);
	 //public List<Map<String, Object>> selectAdminSmUserWithAll(@Param("loginCode") String loginCode);
	 public int updatePassword(Map<String, String> paramMap);
	
}

該接口並沒有任何不同（或者是不知道spring cloud實現原理，所以看不出不同）

3 建立AdminSmUserMapper.xml

</mapper>

其中

resultMap 是爲了實現聯合查詢，其中

association 是一對一的關係

collection是一對多的關係。

該步驟就是爲了把查到的數據映射到相應的domain屬性中。
