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，文末提供自己编写的工具(基于mysql存储过程)：
作者其实就是使用(mybatis-generator)这个工具过程中，有些想法，实践下，编写时很多实现留了口子，后续方便集成到开发框架中。
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：
// 批量插入
@SuppressWarnings("unchecked")
public int batchInsertSapoAdminAccount(Object object) {
// 类型转换，支持单个对象或者集合形式作为入参
List<SapoAdminAccount> list = null;
if (object instanceof SapoAdminAccount) {
