<dependency>

    <artifactId>beetlsql</artifactId>
    <version>2.10.20</version>
</dependency>

内置增删改查

• void insert(T entity);
• int updateById(T entity);
• int updateTemplateById(T entity);
• int deleteById(Object key);
• T unique(Object key);
• T single(Object key);
• T lock(Object key);
• List<T> all();
• List<T> template(T entity);
• <T> T templateOne(T entity);
• List<T> execute(String sql,Object… args);
• …. 等等大量内置方法且可以扩展内置方法

Query 查询

List<User> list = userDao.createQuery().andEq("name","hi").orderBy("create_date").select();

如果是 Java8

List<User> list1  = userDao.createLambdaQuery().andEq(User::getName, "hi").orderBy(User::getCreateDate).select();

管理 SQL

@SqlResource("console.user")  
public interface UserConsoleDao extends BaseMapper<SysUser> {

    void batchDelUserByIds(List<Long> ids);
    void batchUpdateUserState( List<Long> ids,  GeneralStateEnum stateEnum);
    @Sql("update sys_user set password=? where id=?")
    int changePassword(String newPassword,long id);


}

对应的 sql 文件是 console/user.md, 内容如下

batchDelUserByIds
===
    update SYS_USER u set u.del_flag = 1 where u.id in( #join(ids)#)
    
batchUpdateUserState ===
    update SYS_USER u set u.state = #state# where u.id in( #join(ids)#)

关系映射

selectUserAndDepartment
===
    select * from user where user_id=#userId#
    @ orm.single({"departmentId":"id"},"Department");
    @ orm.many({"id":"userId"},"user.selectRole","Role");


user.selectRole
===

    select r.* from user_role ur left join role r on ur.role_id=r.id where ur.user_id=#userId#
