mybatis通用功能程式碼生成工具

mybatis操作資料庫的過程中，如果只考慮單表操作，mapper和dao層基本80%的都是固定的，故而可以使用工具進行生成，文末提供自己編寫的工具(基於mysql存儲過程)：
作者其實就是使用(mybatis-generator)這個工具過程中，有些想法，實踐下，編寫時很多實現留了口子，後續方便集成到開發框架中。
工具提供 mapper,dao層功能如下：
通用查詢,返回對象
通用查詢，返回集合
通用主鍵查詢，返回集合
通過條件和主鍵in查詢,返回集合
通過主鍵更新
通過條件更新
通過條件和主鍵in更新
單條插入，id自增
單條插入，id不自增
批量插入
（如需訂製化生成程式碼,請翻閱前幾篇文章，本文僅將通用性程式碼抽取出來：//www.cnblogs.com/wanglifeng717/p/15839391.html）
- 1.查詢部分示例
因為查詢根據不同條件sql不同,可以使用動態語句。使用對象拼接查詢條件。此時mapper層只需要一個方法。（工具自動生成程式碼如下）
// 通用查詢，返回對象 @Select({ "<script> ", "select t.id as id,t.create_time as create_time,t.last_update_time as last_update_time,t.login_name as login_name,t.login_password as login_password,t.status as status,t.remark as remark,t.admin_user_id as admin_user_id ", "from tbl_sapo_admin_account t ", "<where> ", "<if test='queryObj!=null'>", "<if test = 'queryObj.id!=null'> and id=#{queryObj.id,jdbcType=INTEGER} </if>" , "<if test = 'queryObj.create_time!=null'> and create_time=#{queryObj.createTime,jdbcType=TIMESTAMP} </if>" , "<if test = 'queryObj.last_update_time!=null'> and last_update_time=#{queryObj.lastUpdateTime,jdbcType=TIMESTAMP} </if>" , "<if test = 'queryObj.loginName !=null and queryObj.loginName !='''> and login_name=#{queryObj.loginName,jdbcType=VARCHAR} </if>" , "<if test = 'queryObj.loginPassword !=null and queryObj.loginPassword !='''> and login_password=#{queryObj.loginPassword,jdbcType=VARCHAR} </if>" , "<if test = 'queryObj.status!=null'> and status=#{queryObj.status,jdbcType=INTEGER} </if>" , "<if test = 'queryObj.remark !=null and queryObj.remark !='''> and remark=#{queryObj.remark,jdbcType=VARCHAR} </if>" , "<if test = 'queryObj.admin_user_id!=null'> and admin_user_id=#{queryObj.adminUserId,jdbcType=INTEGER} </if>" , "</if>", "</where> ", "</script>" }) SapoAdminAccount getSapoAdminAccount(@Param("queryObj") SapoAdminAccount sapoAdminAccountForQuery);
- 2.更新部分示例
更新的前提基本都是已經查出來該記錄，直接根據主鍵更新即可。並沒有很多花樣。（工具自動生成程式碼如下）
// 通過主鍵更新 @Update({ "update tbl_sapo_admin_account set ", "create_time=#{updateObj.createTime,jdbcType=TIMESTAMP} ,last_update_time=#{updateObj.lastUpdateTime,jdbcType=TIMESTAMP} ,login_name=#{updateObj.loginName,jdbcType=VARCHAR} ,login_password=#{updateObj.loginPassword,jdbcType=VARCHAR} ,status=#{updateObj.status,jdbcType=INTEGER} ,remark=#{updateObj.remark,jdbcType=VARCHAR} ,admin_user_id=#{updateObj.adminUserId,jdbcType=INTEGER} ", "where id = #{updateObj.id,jdbcType=INTEGER} " }) int updateSapoAdminAccountByPrimaryKey(@Param("updateObj") SapoAdminAccount sapoAdminAccountForUpdate);
如果更新的條件是不確定的，更新的內容也不確定，可以使用動態語句，基本一個更新語句包打天下（工具自動生成程式碼如下：）
// 通過條件更新 @Update({ "<script> ", "update tbl_sapo_admin_account ", "<set>", "<if test='updateObj!=null'>", "<if test = 'updateObj.create_time!=null'> create_time=#{updateObj.createTime,jdbcType=TIMESTAMP} , </if>" , "<if test = 'updateObj.last_update_time!=null'> last_update_time=#{updateObj.lastUpdateTime,jdbcType=TIMESTAMP} , </if>" , "<if test = 'updateObj.loginName !=null and updateObj.loginName !='''> login_name=#{updateObj.loginName,jdbcType=VARCHAR} , </if>" , "<if test = 'updateObj.loginPassword !=null and updateObj.loginPassword !='''> login_password=#{updateObj.loginPassword,jdbcType=VARCHAR} , </if>" , "<if test = 'updateObj.status!=null'> status=#{updateObj.status,jdbcType=INTEGER} , </if>" , "<if test = 'updateObj.remark !=null and updateObj.remark !='''> remark=#{updateObj.remark,jdbcType=VARCHAR} , </if>" , "<if test = 'updateObj.admin_user_id!=null'> admin_user_id=#{updateObj.adminUserId,jdbcType=INTEGER} , </if>" , "</if>", "</set>", "<where>", "<if test='queryObj!=null'>", "<if test = 'queryObj.id!=null'> and id=#{queryObj.id,jdbcType=INTEGER} </if>" , "<if test = 'queryObj.create_time!=null'> and create_time=#{queryObj.createTime,jdbcType=TIMESTAMP} </if>" , "<if test = 'queryObj.last_update_time!=null'> and last_update_time=#{queryObj.lastUpdateTime,jdbcType=TIMESTAMP} </if>" , "<if test = 'queryObj.loginName !=null and queryObj.loginName !='''> and login_name=#{queryObj.loginName,jdbcType=VARCHAR} </if>" , "<if test = 'queryObj.loginPassword !=null and queryObj.loginPassword !='''> and login_password=#{queryObj.loginPassword,jdbcType=VARCHAR} </if>" , "<if test = 'queryObj.status!=null'> and status=#{queryObj.status,jdbcType=INTEGER} </if>" , "<if test = 'queryObj.remark !=null and queryObj.remark !='''> and remark=#{queryObj.remark,jdbcType=VARCHAR} </if>" , "<if test = 'queryObj.admin_user_id!=null'> and admin_user_id=#{queryObj.adminUserId,jdbcType=INTEGER} </if>" , "</if>", "</where>", "</script>" }) int updateSapoAdminAccount(@Param("updateObj") SapoAdminAccount sapoAdminAccountForUpdate,@Param("queryObj") SapoAdminAccount sapoAdminAccountForQuery);
- 3.插入部分示例
// 單條插入:id自增 @Insert({ "insert into tbl_sapo_admin_account ", "(id,create_time,last_update_time,login_name,login_password,status,remark,admin_user_id)", "values ", "(#{item.id,jdbcType=INTEGER} ,#{item.createTime,jdbcType=TIMESTAMP} ,#{item.lastUpdateTime,jdbcType=TIMESTAMP} ,#{item.loginName,jdbcType=VARCHAR} ,#{item.loginPassword,jdbcType=VARCHAR} ,#{item.status,jdbcType=INTEGER} ,#{item.remark,jdbcType=VARCHAR} ,#{item.adminUserId,jdbcType=INTEGER} ) " }) @Options(useGeneratedKeys = true, keyProperty = "id", keyColumn = "id") int insertSapoAdminAccount(@Param("item") SapoAdminAccount sapoAdminAccount);
// 批量插入 @Insert({ "<script> ", "insert into tbl_sapo_admin_account ( id,create_time,last_update_time,login_name,login_password,status,remark,admin_user_id ) values", "<foreach collection='itemList' item='item' index='index' open='(' separator='),(' close=')'>", "#{item.id,jdbcType=INTEGER} ,#{item.createTime,jdbcType=TIMESTAMP} ,#{item.lastUpdateTime,jdbcType=TIMESTAMP} ,#{item.loginName,jdbcType=VARCHAR} ,#{item.loginPassword,jdbcType=VARCHAR} ,#{item.status,jdbcType=INTEGER} ,#{item.remark,jdbcType=VARCHAR} ,#{item.adminUserId,jdbcType=INTEGER} ", "</foreach>", "</script>" }) int batchInsertSapoAdminAccount(@Param("itemList") List<SapoAdminAccount> sapoAdminAccountList);
工具生成dao層程式碼示例：
// 批量插入 @SuppressWarnings("unchecked") public int batchInsertSapoAdminAccount(Object object) { // 類型轉換，支援單個對象或者集合形式作為入參 List<SapoAdminAccount> list = null; if (object instanceof SapoAdminAccount) { list = new ArrayList<>(); list.add((SapoAdminAccount) object); } else if (object instanceof List) { for (Object o : (List<?>) object) { if (!(o instanceof SapoAdminAccount)) { throw new BusinessException(ResultInfo.SYS_INNER_ERROR.getCode(),ResultInfo.SYS_INNER_ERROR.getDesc() + ",error element: " + o.toString() + ",object type is error for batch insert" + BizLogUtils.getValueOfBizId()); } } list = (List<SapoAdminAccount>) object; } else { throw new BusinessException(ResultInfo.SYS_INNER_ERROR.getCode(),ResultInfo.SYS_INNER_ERROR.getDesc() + ",object type is error for batch insert" + BizLogUtils.getValueOfBizId()); } // 如果集合為空則報異常 if (list == null || list.size() == 0) { throw new BusinessException(ResultInfo.SYS_INNER_ERROR.getCode(),ResultInfo.SYS_INNER_ERROR.getDesc() + ",batch insert empty ,bizId=" + BizLogUtils.getValueOfBizId()); } // 插入閾值， 每多少條commit一次，默認是200條做一次。 int threshold = 200; int result = 0; int sum = list.size(); int end = 0; for (int i = 0; i < sum; i = i + threshold) { end = i + threshold > sum ? sum : i + threshold; try { result += mapper.batchInsertSapoAdminAccount(list.subList(i, end)); } catch (Exception e) { // 根據業務做補償機制，例如通過end值，將之前插入的值全部刪除或者狀態翻轉為無效 batchInsertSapoAdminAccountFailOffset(list.subList(0, end));
