notDefaultSelectAll() 不默认查询主表全部的字段

WARNING

因为默认是查询主表所有查询字段，如果不需要查询主表全部字段就调用该方法notDefaultSelectAll()

JoinLambdaWrapper<Users> wrapper = new JoinLambdaWrapper<>(new Users().setUserName("name啊")
                                                                          .setUserId(1L));

wrapper.notDefaultSelectAll()
    .leftJoin(UsersAge.class,UsersAge::getId,Users::getAgeId)
	.eq(UserAge::getAgeName,"95")
  	.select(UserAge::getAgeName).end();

// 执行查询
usersService.joinList(wrapper,UsersVo.class);

// 执行SQL 
select 
  users_age.age_name
from users users
  left join users_age users_age on users_age.id = users.age_id
where 
 users.user_id = 1
 and users.user_name = 'name啊'
 and users_age.age_name = '95'
