| QueryWrapper
查询包装对象:
QueryWrapper<UserEntity> query = mapperManage.createQuery(
"select * from t_user where id>#{id}",
UserEntity.class);
query.addParam("id", 2);
List<UserEntity> list = query.getList();
System.out.println(list);

| UpadateWrapper
更新包装对象，例1 ：
UpadateWrapper update = mapperManage.createUpdate("update t_user set password=#{p} where id=#{id}");
update.addParam("p", System.currentTimeMillis()).addParam("id", 1);
int execute = update.execute();
log.info("受影响行数: {}", execute);
例2：
UpadateWrapper update = mapperManage.createUpdate("insert into t_user(id,username) values (2,#{un})");
update.addParam("un", "lk");
int execute = update.execute();
log.info("受影响行数: {}", execute);
