在ABP框架中，可以使用动态表单来实现“租户表单”的功能。下面是一个示例解决方案的代码示例：

1. 创建租户表单实体类

public class TenantForm : FullAuditedAggregateRoot
{
    public string FormName { get; set; }
    public string FormJson { get; set; }
    // 其他属性...
}

2. 创建租户表单应用服务接口

public interface ITenantFormAppService : IApplicationService
{
    Task CreateTenantFormAsync(string formName, string formJson);
    Task GetTenantFormAsync(Guid id);
    // 其他方法...
}

3. 实现租户表单应用服务

public class TenantFormAppService : ApplicationService, ITenantFormAppService
{
    private readonly IRepository _tenantFormRepository;

    public TenantFormAppService(IRepository tenantFormRepository)
    {
        _tenantFormRepository = tenantFormRepository;
    }

    public async Task CreateTenantFormAsync(string formName, string formJson)
    {
        var tenantForm = new TenantForm
        {
            FormName = formName,
            FormJson = formJson
        };

        return await _tenantFormRepository.InsertAndGetIdAsync(tenantForm);
    }

    public async Task GetTenantFormAsync(Guid id)
    {
        var tenantForm = await _tenantFormRepository.GetAsync(id);
        return ObjectMapper.Map(tenantForm);
    }

    // 其他方法的实现...
}

4. 创建租户表单控制器

public class TenantFormController : AbpController
{
    private readonly ITenantFormAppService _tenantFormAppService;

    public TenantFormController(ITenantFormAppService tenantFormAppService)
    {
        _tenantFormAppService = tenantFormAppService;
    }

    [HttpPost]
    public async Task CreateTenantForm(string formName, string formJson)
    {
        var id = await _tenantFormAppService.CreateTenantFormAsync(formName, formJson);
        return Ok(id);
    }

    [HttpGet]
    public async Task GetTenantForm(Guid id)
    {
        var tenantForm = await _tenantFormAppService.GetTenantFormAsync(id);
        return Ok(tenantForm);
    }

    // 其他方法...
}

这样，你就可以使用ABP框架来创建和获取“租户表单”了。你可以根据实际需求来扩展和修改代码。
