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中的人性化的设计
1.如果我们想要在appsettings.json里配置web应用的ip和port该怎么办?1.在appsettings.json里直接写
{
"urls":"http://localhost:7002;http://localhost:7012"
}
也可以使用summerboot增强的方式,在program.cs中,添加UseSummerBoot()
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>().UseSummerBoot();
});
然后在appsettings.json里直接写
{
"server": {
"ip":"127.0.0.1",
"port": 8048
},
}
- AutoRegister注解,作用是让框架自动将接口和接口的实现类注册到IOC容器中,标注在实现类上,注解的参数为这个类对应的自定义接口的type和服务的生命周期ServiceLifetime(周期默认为scope级别),使用方式如下:
public interface ITest
{
}
[AutoRegister(typeof(ITest),ServiceLifetime.Transient)]
public class Test:ITest
{
}
- ApiResult 接口返回值包装类,包含 code,msg和data,3个字段,让整个系统的返回值统一有序,有利于前端的统一拦截,统一操作。使用方式如下:
[HttpPost("CreateServerConfigAsync")]
public async Task<ApiResult<bool>> CreateServerConfigAsync(ServerConfigDto dto)
{
var result = await serverConfigService.CreateServerConfigAsync(dto);
return ApiResult<bool>.Ok(result);
}
- 对net core mvc的一些增强操作,包括全局错误拦截器,和接口参数校验失败后的处理,配合ApiResult,使得系统报错时,也能统一返回,使用方式如下,首先在startUp里注册该服务,注意,要放在mvc注册之后:
services.AddControllersWithViews();
services.AddSummerBootMvcExtension(it =>
{
//是否启用全局错误处理
it.UseGlobalExceptionHandle = true;
//是否启用参数校验处理
it.UseValidateParameterHandle = true;
});
4.1 全局错误拦截器使用后的效果 我们可以直接在业务代码里抛出错误,全局错误拦截器会捕捉到该错误,然后使用统一格式返回给前端,业务代码如下:
private void ValidateData(EnvConfigDto dto)
{
if (dto == null)
{
throw new ArgumentNullException("参数不能为空");
}
if(dto.ServerConfigs==null|| dto.ServerConfigs.Count==0)
{
throw new ArgumentNullException("环境下没有配置服务器");
}
}
如果业务代码里报错,则返回值如下:
{
"code": 40000,
"msg": "Value cannot be null. (Parameter '环境下没有配置服务器')",
"data": null
}
4.2 接口参数校验失败后的处理的效果 我们在接口的参数dto里添加校验注解,代码如下
public class EnvConfigDto : BaseEntity
{
/// <summary>
/// 环境名
/// </summary>
[Required(AllowEmptyStrings = false, ErrorMessage = "环境名称不能为空")]
public string Name { get; set; }
/// <summary>
/// 环境下对应的服务器
/// </summary>
[NotMapped]
public List<int> ServerConfigs { get; set; }
}
如果参数校验不通过,则返回值如下:
{
"code": 40000,
"msg": "环境名称不能为空",
"data": null
}
- QueryCondition,lambda查询条件组合,解决前端传条件过来进行过滤查询的痛点,除了基本的And和Or方法,还添加了更人性化的方法,一般前端传过来的dto里的属性,有字符串类型,如果他们有值则添加到查询条件里,所以特地提取了2个方法,包括了AndIfStringIsNotEmpty(如果字符串不为空则进行and操作,否则返回原表达式),OrIfStringIsNotEmpty(如果字符串不为空则进行or操作,否则返回原表达式), 同时dto里的属性,还有可能是nullable类型,即可空类型,比如 int? test代表用户是否填写某个过滤条件,如果hasValue则添加到查询条件里,所以特地提取了2个方法,AndIfNullableHasValue(如果可空值不为空则进行and操作,否则返回原表达式),OrIfNullableHasValue(如果可空值不为空则进行and操作,否则返回原表达式)用法如下:
//dto
public class ServerConfigPageDto : IPageable
{
public int PageNumber { get; set; }
public int PageSize { get; set; }
/// <summary>
/// ip地址
/// </summary>
public string Ip { get; set; }
/// <summary>
/// 连接名
/// </summary>
public string ConnectionName { get; set; }
public int? Test { get; set; }
}
//condition
var queryCondition = QueryCondition.True<ServerConfig>()
.And(it => it.Active == 1)
//如果字符串不为空则进行and操作,否则返回原表达式
.AndIfStringIsNotEmpty(dto.Ip, it => it.Ip.Contains(dto.Ip))
//如果可空值不为空则进行and操作,否则返回原表达式
.AndIfNullableHasValue(dto.Test,it=>it.Test==dto.Test)
.AndIfStringIsNotEmpty(dto.ConnectionName,it=>it.ConnectionName.Contains(dto.ConnectionName));
var queryResult = await serverConfigRepository.Where(queryCondition)
.Skip((dto.PageNumber - 1) * dto.PageSize).Take(dto.PageSize).ToPageAsync();
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";
//插入的时候自动添加创建时间,数据库实体类必须继承于BaseEntity,oracle继承于OracleBaseEntity
it.AutoUpdateLastUpdateOn = true;
//插入的时候自动添加创建时间,使用utc时间
it.AutoUpdateLastUpdateOnUseUtc = false;
//update的时候自动更新最后更新时间字段,数据库实体类必须继承于BaseEntity,oracle继承于OracleBaseEntity
it.AutoAddCreateOn = true;
//update的时候自动更新最后更新时间字段,使用utc时间
it.AutoAddCreateOnUseUtc = false;
//启用软删除,数据库实体类必须继承于BaseEntity,oracle继承于OracleBaseEntity
it.IsUseSoftDelete = true;
});
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,同时自定义了一部分注解,比如更新时忽略该列IgnoreWhenUpdateAttribute(主要用在创建时间这种在update的时候不需要更新的字段), 同时SummerBoot自带了一个基础实体类BaseEntity(oracle 为OracleBaseEntity),实体类里包括自增的id,创建人,创建时间,更新人,更新时间以及软删除标记,推荐实体类直接继承BaseEntity
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
通过IOC注入获得接口以后,就可以开始查了,支持正常查询与分页查询,查询有2种方式。
1.1 IQueryable链式语法查询。
//常规查询
var customers= customerRepository.Where(it => it.Age > 5).OrderBy(it => it.Id).Take(10).ToList();
//分页
var page2 = await customerRepository.Where(it => it.Age > 5).Skip(0).Take(10).ToPageAsync();
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:1.2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。
增
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);
删
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);
改
1.1 接口自带了Update方法,可以更新单个实体,或者实体列表,联合主键的话,数据库实体类对应的多字段都添加key注解即可。
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AutoRegister注解,注解的参数为这个类对应的自定义接口的类型和服务的声明周期ServiceLifetime(周期默认为scope级别),添加AutoRegister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);
}
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。
