mybatis通用功能代码生成工具
mybatis操作数据库的过程中，如果只考虑单表操作，mapper和dao层基本80%的都是固定的，故而可以使用工具进行生成代码，文末提供自己编写的工具(基于mysql存储过程)还有升级版的通用的 dao和mapper层java代码：
工具提供 mapper,dao层功能如下：
- 通用查询,返回对象
- 通用查询，返回集合
- 通用分页查询
- 通用主键查询，返回集合
- 通过条件和主键in查询,返回集合
- 通过主键更新
- 通过条件更新
- 通过更新带强制字段校验（乐观锁）
- 通过条件和主键in更新
- 单条插入，id自增
- 单条插入，id不自增
- 批量插入
- ........
（如需定制化生成代码,请翻阅前几篇文章，本文仅将通用性代码抽取出来：https://www.cnblogs.com/wanglifeng717/p/15839391.html）
- 1.查询部分示例
因为查询根据不同条件sql不同,可以使用动态语句。使用对象拼接查询条件。此时mapper层只需要一个方法。（工具自动生成代码如下）
// 通用查询，返回对象 @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经查出来该记录，直接根据主键更新即可。并没有很多花样。（工具自动生成代码如下）
// 通过主键更新 @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);
如果更新的条件是不确定的，更新的内容也不确定，可以使用动态语句，基本一个更新语句包打天下（工具自动生成代码如下：）
// 通过条件更新 @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
// 单条插入: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层代码示例

升级方案：
以上做法问题是，每个表都要生成一份通用代码。
可以写一个通用模式。所有表的操作都使用相同的dao、mapper层代码。
表和表之间的区别通过反射实体类字段来区分。
思路如下：
- mapper层使用mybatis动态语句标签。
- 查询的字段名列表通过反射拼接进去。
- 查询的表名通过实体类名反射出表名拼接出来。
- 查询条件通过实体类反射字段值的有无拼接出查询条件。
- mapper层返回Map<String,Object>,在dao层反射生成实例类。
- 更新和插入同理。
通用方法如下：
| 限定符和类型 | 方法和说明 |
|---|---|
<T> void |
deleteObj(T objForDelete)
通用删除。

<T> T |
getObj(T objForQuery)

|
<T,E> java.util.List<T> |
getObjListUseIn(T objForQuery, java.lang.String inCol, java.util.List<E> itemList)
通用条件查询，使用in条件，返回集合不为空，否则报错(set,where都不包含null字段)。
