SummerBoot的核心理念

将SpringBoot的先进理念与C#的简洁优雅合二为一,声明式编程,专注于”做什么”而不是”如何去做”。在更高层面写代码,更关心的是目标,而不是底层算法实现的过程,SummerBoot,致力于让.net开发变得更简单。

Getting Started

Nuget

你可以运行以下命令在你的项目中安装 SummerBoot。

PM> Install-Package SummerBoot

支持框架

net core 3.1,net 5,net 6

说明

这是一个全声明式框架,用户只需要声明接口,框架会通过Reflection Emit技术,自动生成接口的实现类。

SummerBoot 如何操作数据库

底层基于dapper,上层通过模板模式,支持了常见的4种数据库类型(sqlserver,mysql,oracle,sqlite)的增删改查操作,如果有其他数据库需求,可以参考以上4个的源码,给本项目贡献代码,同时基于工作单元模式实现了事务。不支持多表的lambda查询,因为多表查询直接写sql更好更易理解。

准备工作

需要自己通过nuget安装相应的数据库依赖包,比如SqlServer的Microsoft.Data.SqlClient,mysql的Mysql.data, oracle的Oracle.ManagedDataAccess.Core

首先在startup.cs类中注册服务

services.AddSummerBoot();

services.AddSummerBootRepository(it =>
{
    //注册数据库类型,比如SqliteConnection,MySqlConnection,OracleConnection,SqlConnection
    it.DbConnectionType = typeof(SqliteConnection);
    //添加数据库连接字符串
    it.ConnectionString = "Data source=./mydb.db";
});

定义一个数据库实体类

其中注解大部分来自于系统自带的命名空间System.ComponentModel.DataAnnotations 和 System.ComponentModel.DataAnnotations.Schema,比如表名Table,主键Key,主键自增DatabaseGenerated(DatabaseGeneratedOption.Identity),列名Column,不映射该字段NotMapped等

public class Customer
{
    [Key,DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public int Id { set; get; }

    public string Name { set; get; }
    
    public int Age { set; get; } = 0;
    
    /// <summary>
    /// 会员号
    /// </summary>
    public string CustomerNo { set; get; }
    
    /// <summary>
    /// 总消费金额
    /// </summary>
    public decimal TotalConsumptionAmount { set; get; }
}

定义接口,并继承于IBaseRepository,同时添加AutoRepository注解表示让框架自动注册并生成实现类

[AutoRepository]
public interface ICustomerRepository : IBaseRepository<Customer>
{
}

增删改查操作,均支持异步同步

1. 查,支持正常查询与分页查询

通过IOC注入获得接口以后,就可以开始查了,支持2种方式。

1.1 IQueryable链式语法查询。
var customers= customerRepository.Where(it => it.Age > 5).OrderBy(it => it.Id).Take(10).ToList();
1.2 直接在接口里定义方法,并且在方法上加上注解Select,然后在Select里写sql语句
[AutoRepository]
public interface ICustomerRepository : IBaseRepository<Customer>
{
    //async
    [Select("select od.productName from customer c join orderHeader oh on c.id=oh.customerid" +
            " join orderDetail od on oh.id=od.OrderHeaderId where c.name=@name")]
    Task<List<CustomerBuyProduct>> QueryAllBuyProductByNameAsync(string name);

    [Select("select * from customer where age>@age order by id")]
    Task<Page<Customer>> GetCustomerByPageAsync(IPageable pageable, int age);

    //sync
    [Select("select od.productName from customer c join orderHeader oh on c.id=oh.customerid" +
            " join orderDetail od on oh.id=od.OrderHeaderId where c.name=@name")]
    List<CustomerBuyProduct> QueryAllBuyProductByName(string name);

    [Select("select * from customer where age>@age order by id")]
    Page<Customer> GetCustomerByPage(IPageable pageable, int age);

}

使用方法:

var result = await customerRepository.QueryAllBuyProductByNameAsync("testCustomer");

//page
var pageable = new Pageable(1, 10);
var page = customerRepository.GetCustomerByPage(pageable, 5);
1.3 注意:方式2查询里的分页支持,方法的返回值由Page这个类包裹,同时方法参数里必须包含 IPageable这个分页参数,sql语句里也要有order by,例如:
[Select("select * from customer where age>@age order by id")]
Page<Customer> GetCustomerByPage(IPageable pageable, int age);
1.4 接口同时自带了Get方法,通过id获取结果,和GetAll(),获取表里的所有结果集。

接口自带了Insert方法,可以插入单个实体,或者实体列表,如果实体类的主键名称为Id,且有Key注解,并且是自增的,那么插入后,框架会自动为实体的ID这个字段赋值,值为自增的ID值。
var customer = new Customer() { Name = "testCustomer" };
customerRepository.Insert(customer);

var customer2 = new Customer() { Name = "testCustomer2" };
var customer3 = new Customer() { Name = "testCustomer3" };
var customerList = new List<Customer>() { customer2, customer3 };
customerRepository.Insert(customerList);

1.1 接口自带了Delete方法,可以删除单个实体,或者实体列表
customerRepository.Delete(customer);

customerRepository.Delete(customerList);
1.2 同时还支持基于lambda表达式的删除,返回受影响的行数,例如
 var deleteCount = customerRepository.Delete(it => it.Age > 5);

1.1 接口自带了Update方法,可以更新单个实体,或者实体列表
customerRepository.Update(customer);

customerRepository.Update(customerList);
1.2 同时还支持基于IQueryable链式语法的更新方式,返回受影响的行数,例如
var updateCount= customerRepository.Where(it=>it.Name == "testCustomer")
.SetValue(it=>it.Age,5)
.SetValue(it=>it.TotalConsumptionAmount,100)
.ExecuteUpdate();

事务支持

事务支持,需要在使用的时候注入自定义仓储接口的同时,也注入框架自带的IUnitOfWork接口,用法如下
//uow is IUnitOfWork interface
try
{
    uow.BeginTransaction();
    customerRepository.Insert(new Customer() { Name = "testCustomer2" });
    var orderDetail3 = new OrderDetail
    {
        OrderHeaderId = orderHeader.Id,
        ProductName = "ball",
        Quantity = 3
    };
    orderDetailRepository.Insert(orderDetail3);
    uow.Commit();
}
catch (Exception e)
{
    uow.RollBack();
}

如果有些特殊情况要求自己手写实现类怎么办?

1.1 定义一个接口继承于IBaseRepository,并且在接口中定义自己的方法,注意,此时该接口无需添加AutoRepository注解
public interface ICustomCustomerRepository : IBaseRepository<Customer>
{
    Task<List<Customer>> GetCustomersAsync(string name);

    Task<Customer> GetCustomerAsync(string name);

    Task<int> UpdateCustomerNameAsync(string oldName, string newName);

    Task<int> CustomQueryAsync();
}
1.2 添加一个实现类,继承于BaseRepository类和自定义的ICustomCustomerRepository接口,实现类添加ManualRepository注解,注解的参数为这个类对应的自定义接口的类型,添加ManualRepository注解的目的是让模块自动将自定义接口和自定义类注册到IOC容器中,后续直接注入使用即可,BaseRepository自带了Execute,QueryFirstOrDefault和QueryList方法,如果要接触更底层的dbConnection进行查询,参考下面的CustomQueryAsync方法,首先OpenDb(),然后查询,查询中一定要带上transaction:dbTransaction这个参数,查询结束以后CloseDb();
[ManualRepository(typeof(ICustomCustomerRepository))]
public class CustomCustomerRepository : BaseRepository<Customer>, ICustomCustomerRepository
{
    public CustomCustomerRepository(IUnitOfWork uow, IDbFactory dbFactory, RepositoryOption repositoryOption) : base(uow, dbFactory, repositoryOption)
    {
    }

    public async Task<Customer> GetCustomerAsync(string name)
    {
        var result =
            await this.QueryFirstOrDefaultAsync<Customer>("select * from customer where name=@name", new { name });
        return result;
    }

    public async Task<List<Customer>> GetCustomersAsync(string name)
    {
        var result = await this.QueryListAsync<Customer>("select * from customer where name=@name", new { name });

        return result;
    }

    public async Task<int> UpdateCustomerNameAsync(string oldName, string newName)
    {
        var result = await this.ExecuteAsync("update customer set name=@newName where name=@oldName", new { newName, oldName });
        return result;
    }

    public async Task<int> CustomQueryAsync()
    {
        this.OpenDb();
        var grid = await this.dbConnection.QueryMultipleAsync("select id from customer",transaction:dbTransaction);
        var id = grid.Read().FirstOrDefault()?.id;
        this.CloseDb();
        return id;
    }
}

SummerBoot如何操作http调用,我们使用Feign

在startup.cs类中注册服务

services.AddSummerBoot();

//添加feign请求拦截器
services.AddScoped<IRequestInterceptor,MyRequestInterceptor>();
services.AddSummerBootFeign();

编写接口,包括get,post(json方式),post(form表单形式),异常处理包括超时重试回退降级等

/// <summary>
    /// 会员接口
    /// </summary>
    [FeignClient(name: "CustomerService", url: "http://localhost:5001/", fallBack: typeof(CustomerFallBack))]
    [Polly(retry:3,timeout:2000,retryInterval:1000)]
    public interface ICustomerRepository
    {
        /// <summary>
        /// 更新会员总消费金额
        /// </summary>
        /// <param name="customerNo"></param>
        /// <param name="amount"></param>
        /// <returns></returns>
        [PostMapping("/Customer/UpdateCustomerAmount")]
        [Headers("Content-Type:application/json", "Accept:application/json", "Charset:utf-8")]
        Task<bool> UpdateCustomerAmount(string customerNo, decimal amount);
    }
	
 [FeignClient(name: "testFeign", url: "http://localhost:5001/")]
     [Polly(retry:3,timeout:2000,retryInterval:1000)]
     public interface IFeignExampleRepository
     {
         /// <summary>
         /// post(json方式)
         /// </summary>
         /// <param name="name"></param>
         /// <param name="dto"></param>
         /// <returns></returns>
         [PostMapping("/demo/TestJson")]
         [Headers("Content-Type:application/json", "Accept:application/json", "Charset:utf-8")]
         Task<int> TestJson(string name,[Body]AddOrderDto dto);
 
         /// <summary>
         /// post(form方式)
         /// </summary>
         /// <param name="dto"></param>
         /// <returns></returns>
         [PostMapping("/demo/TestForm")]
         Task<bool> TestForm([Form]FeignFormDto dto);
 
         /// <summary>
         /// get
         /// </summary>
         /// <param name="name"></param>
         /// <param name="age"></param>
         /// <returns></returns>
         [GetMapping("/demo/GetTest")]
         Task<DateTime> TestGet(string name,int age);
     }

注入即可直接调用

框架中的一些接口

  • IUnitOfWork。工作单元接口,熟悉工作单元的,可重写该接口,并注入到框架中。

  • IRepository。自定义仓储接口,框架默认底层实现基于dapper,可重写替换。

  • IDbFactory。生成IDbConnection的工厂接口,可重写替换。

更新记录

  • 2020-08-05 feign调用接口返回的状态码如果不是200,则抛出错误。feign里默认的client用的httpClient的超时时长改成3天。修复unitofwork里callback方法里的bug。
