其他 2020-04-17 22:34:14 阅读次数: 0

基础层

1、Cloud.Core项目是核心项目，主要实现缓存的操作、dapper操作、EFRepository、PageList、日志等操作

2、Cloud.Utility属于帮助类

领域层

3、Cloud.Entity实体对象，存放数据库映射实体、FluentAPI配置、枚举字典、DbContext等

4、Cloud.UnitOfWork，操作数据库的网关，里面封装了对仓储的操作、dapper的操作、事务等

服务层

5、Cloud.Service业务逻辑的实现

6、Cloud.Dto数据传输对象，实体对象不直接和表现层接触，通过dto互转

表现层

7、Cloud.Framework，表现层框架，封装了超类controller，全局授权过滤器，全局异常过滤器，ActionFilter,HtmlHelper等操作

8、Cloud.Boss启动项目

使用的技术

基于.NETCore2.0的ASP.NETCoreMVC

基于.NETCore2.0的EF

Dapper

Mysql

前端框架：aceAdmin（http://ace.jeka.by/#）

技术要点

1、实体基类定义

2、泛型仓储的封装

2.1、仓储接口的定义，泛型约束T必须是BaseEntity类型

publicinterfaceIRepository whereT:BaseEntity

{

DatabaseFacadeDatabase{get;}

IQueryable Entities{get;}

intSaveChanges();

Task SaveChangesAsync();

voidDisposed();

boolDelete(List entitys,boolisSaveChange=true);

boolDelete(Tentity,boolisSaveChange=true);

Task DeleteAsync(List entitys,boolisSaveChange=true);

Task DeleteAsync(Tentity,boolisSaveChange=true);

Task GetAsync(Expression >predicate=null);

Task >GetListAsync(Expression >predicate=null);

TGet(objectid);

TGet(Expression >predicate=null);

Task GetAsync(objectid);

Task >LoadAsync(Expression >predicate=null);

boolInsert(List entitys,boolisSaveChange=true);

boolInsert(Tentity,boolisSaveChange=true);

Task InsertAsync(List entitys,boolisSaveChange=true);

Task InsertAsync(Tentity,boolisSaveChange=true);

boolUpdate(List entitys,boolisSaveChange=true);

boolUpdate(Tentity,boolisSaveChange=true,List updatePropertyList=null);

Task UpdateAsync(List entitys,boolisSaveChange=true);

Task UpdateAsync(Tentity,boolisSaveChange=true,List updatePropertyList=null);

}

publicinterfaceIRepository whereT:BaseEntity

{

DatabaseFacadeDatabase{get;}

IQueryable Entities{get;}

intSaveChanges();

Task SaveChangesAsync();

voidDisposed();

boolDelete(List entitys,boolisSaveChange=true);

boolDelete(Tentity,boolisSaveChange=true);

Task DeleteAsync(List entitys,boolisSaveChange=true);

Task DeleteAsync(Tentity,boolisSaveChange=true);

Task GetAsync(Expression >predicate=null);

Task >GetListAsync(Expression >predicate=null);

TGet(objectid);

TGet(Expression >predicate=null);

Task GetAsync(objectid);

Task >LoadAsync(Expression >predicate=null);

boolInsert(List entitys,boolisSaveChange=true);

boolInsert(Tentity,boolisSaveChange=true);

Task InsertAsync(List entitys,boolisSaveChange=true);

Task InsertAsync(Tentity,boolisSaveChange=true);

boolUpdate(List entitys,boolisSaveChange=true);

boolUpdate(Tentity,boolisSaveChange=true,List updatePropertyList=null);

Task UpdateAsync(List entitys,boolisSaveChange=true);

Task UpdateAsync(Tentity,boolisSaveChange=true,List updatePropertyList=null);

}

3、表部分字段更新实现

EF默认的更新方式是一个实体对应的表全部字段更新，那么我们想更新表的部分字段怎么处理？

首先定义需要更新的字段：

publicclassPropertyExpression whereT:BaseEntity

{

privatePropertyExpression(){}

privatestaticList propertyList=newList ();

publicstaticPropertyExpression Init

{

get

{

propertyList.Clear();

returnnewPropertyExpression ();

}

}

publicPropertyExpression Property(Expression >expr)

{

varrtn="";

if(expr.BodyisUnaryExpression)

{

rtn=((MemberExpression)((UnaryExpression)expr.Body).Operand).Member.Name;

}

elseif(expr.BodyisMemberExpression)

{

rtn=((MemberExpression)expr.Body).Member.Name;

}

elseif(expr.BodyisParameterExpression)

{

rtn=((ParameterExpression)expr.Body).Type.Name;

}

propertyList.Add(rtn);

returnthis;

}

publicList ToList()

{

returnpropertyList;

}

}

publicclassPropertyExpression whereT:BaseEntity

{

privatePropertyExpression(){}

privatestaticList propertyList=newList ();

publicstaticPropertyExpression Init

{

get

{

propertyList.Clear();

returnnewPropertyExpression ();

}

}

publicPropertyExpression Property(Expression >expr)

{

varrtn="";

if(expr.BodyisUnaryExpression)

{

rtn=((MemberExpression)((UnaryExpression)expr.Body).Operand).Member.Name;

}

elseif(expr.BodyisMemberExpression)

{

rtn=((MemberExpression)expr.Body).Member.Name;

}

elseif(expr.BodyisParameterExpression)

{

rtn=((ParameterExpression)expr.Body).Type.Name;

}

propertyList.Add(rtn);

returnthis;

}

publicList ToList()

{

returnpropertyList;

}

}

EF更新的处理

publicboolUpdate(Tentity,boolisSaveChange=true,List updatePropertyList=null)

{

if(entity==null)

{

returnfalse;

}

_dbContext.Set ().Attach(entity);

if(updatePropertyList==null)

{

_dbContext.Entry (entity).State=EntityState.Modified;//全字段更新

}

else

{

updatePropertyList.ForEach(c=>{

_dbContext.Entry(entity).Property(c).IsModified=true;//部分字段更新的写法

});

}

if(isSaveChange)

{

returnSaveChanges()>0;

}

returnfalse;

}

publicboolUpdate(Tentity,boolisSaveChange=true,List updatePropertyList=null)

{

if(entity==null)

{

returnfalse;

}

_dbContext.Set ().Attach(entity);

if(updatePropertyList==null)

{

_dbContext.Entry (entity).State=EntityState.Modified;//全字段更新

}

else

{

updatePropertyList.ForEach(c=>{

_dbContext.Entry(entity).Property(c).IsModified=true;//部分字段更新的写法

});

}

if(isSaveChange)

{

returnSaveChanges()>0;

}

returnfalse;

}

使用

varentity=_unitOfWork.SysRoleRep.Get(model.RoleId);

if(entity==null)

{

thrownewException("要查找的对象不存在");

}

entity.Name=model.RoleName;

varupdatedPropertyList=PropertyExpression .Init.Property(c=>c.Name).ToList();

_unitOfWork.SysRoleRep.Update(entity,true,updatedPropertyList);

varentity=_unitOfWork.SysRoleRep.Get(model.RoleId);

if(entity==null)

{

thrownewException("要查找的对象不存在");

}

entity.Name=model.RoleName;

varupdatedPropertyList=PropertyExpression .Init.Property(c=>c.Name).ToList();

_unitOfWork.SysRoleRep.Update(entity,true,updatedPropertyList);

4、动态加载实体到DbContext

publicclassEntityTypeConfiguration :IEntityTypeConfiguration whereT:class

{

publicvoidConfigure(EntityTypeBuilder builder)

{

RelyConfigure(builder);

}

publicvirtualvoidRelyConfigure(EntityTypeBuilder builder)

{

}

}

publicclassEntityTypeConfiguration :IEntityTypeConfiguration whereT:class

{

publicvoidConfigure(EntityTypeBuilder builder)

{

RelyConfigure(builder);

}

publicvirtualvoidRelyConfigure(EntityTypeBuilder builder)

{

}

}

publicclassSys_Error_LogConfiguration:EntityTypeConfiguration

{

publicoverridevoidRelyConfigure(EntityTypeBuilder builder)

{

builder.ToTable("sys_error_log");

builder.HasKey(x=>x.Id);

base.RelyConfigure(builder);

}

}

publicclassSys_Error_LogConfiguration:EntityTypeConfiguration

{

publicoverridevoidRelyConfigure(EntityTypeBuilder builder)

{

builder.ToTable("sys_error_log");

builder.HasKey(x=>x.Id);

base.RelyConfigure(builder);

}

}

publicclassEfDbContext:DbContext

{

publicEfDbContext(DbContextOptions options):base(options)

{

}

//配置数据库连接

protectedoverridevoidOnConfiguring(DbContextOptionsBuilderoptionsBuilder)

{

//optionsBuilder.UseSqlServer("xxxxconnectionstring");

base.OnConfiguring(optionsBuilder);

}

//第一次使用EF功能时执行一次，以后不再执行

protectedoverridevoidOnModelCreating(ModelBuildermodelBuilder)

{

//获取当前程序集中有基类并且基类是泛型的类

vartypesToRegister=Assembly.GetExecutingAssembly().GetTypes().Where(c=>c.BaseType!=null&&c.BaseType.IsGenericType).ToList();

foreach(vartypeintypesToRegister)

{

//泛型定义相同

if(type.BaseType.GetGenericTypeDefinition()==typeof(EntityTypeConfiguration<>))

{

dynamicconfigurationInstance=Activator.CreateInstance(type);

modelBuilder.ApplyConfiguration(configurationInstance);

}

}

base.OnModelCreating(modelBuilder);

}

}

publicclassEfDbContext:DbContext

{

publicEfDbContext(DbContextOptions options):base(options)

{

}

//配置数据库连接

protectedoverridevoidOnConfiguring(DbContextOptionsBuilderoptionsBuilder)

{

//optionsBuilder.UseSqlServer("xxxxconnectionstring");

base.OnConfiguring(optionsBuilder);

}

//第一次使用EF功能时执行一次，以后不再执行

protectedoverridevoidOnModelCreating(ModelBuildermodelBuilder)

{

//获取当前程序集中有基类并且基类是泛型的类

vartypesToRegister=Assembly.GetExecutingAssembly().GetTypes().Where(c=>c.BaseType!=null&&c.BaseType.IsGenericType).ToList();

foreach(vartypeintypesToRegister)

{

//泛型定义相同

if(type.BaseType.GetGenericTypeDefinition()==typeof(EntityTypeConfiguration<>))

{

dynamicconfigurationInstance=Activator.CreateInstance(type);

modelBuilder.ApplyConfiguration(configurationInstance);

}

}

base.OnModelCreating(modelBuilder);

}

}

5、工作单元

工作单元是对仓储和事务的封装

6、业务的实现方式

以前我是service中直接创建仓储然后用仓储操作数据库，方式如下：

这种方式比较繁琐，后来我将创建仓储统一放在工作单元中进行，在service中直接创建UnitOfWork，方式如下：

7、Service的动态注册

publicstaticclassAutoIocRegister

{

///

///动态注入IOC，注意类和接口的命名规则，接口在类名前面加"I"

///

///

/// 程序集名称

publicstaticvoidBatchAddScoped(thisIServiceCollectionservices,stringassemblyName)

{

varlibs=DependencyContext.Default.CompileLibraries;

varserviceLib=libs.Where(c=>c.Name.Contains(assemblyName)).FirstOrDefault();

varassembly=AssemblyLoadContext.Default.LoadFromAssemblyName(newAssemblyName(serviceLib.Name));

varserviceClassList=assembly.GetTypes().Where(c=>c.IsClass).ToList();

foreach(variteminserviceClassList)

{

varinterfaceName="I"+item.Name;

varinterfaceType=assembly.GetTypes().Where(c=>c.IsInterface&&c.Name==interfaceName).FirstOrDefault();

if(interfaceType==null)continue;

services.AddScoped(interfaceType,item);

}

}

}

publicstaticclassAutoIocRegister

{

///

///动态注入IOC，注意类和接口的命名规则，接口在类名前面加"I"

///

///

/// 程序集名称

publicstaticvoidBatchAddScoped(thisIServiceCollectionservices,stringassemblyName)

{

varlibs=DependencyContext.Default.CompileLibraries;

varserviceLib=libs.Where(c=>c.Name.Contains(assemblyName)).FirstOrDefault();

varassembly=AssemblyLoadContext.Default.LoadFromAssemblyName(newAssemblyName(serviceLib.Name));

varserviceClassList=assembly.GetTypes().Where(c=>c.IsClass).ToList();

foreach(variteminserviceClassList)

{

varinterfaceName="I"+item.Name;

varinterfaceType=assembly.GetTypes().Where(c=>c.IsInterface&&c.Name==interfaceName).FirstOrDefault();

if(interfaceType==null)continue;

services.AddScoped(interfaceType,item);

}

}

}

调用：

services.BatchAddScoped("Cloud.Service");

services.BatchAddScoped("Cloud.Service");

8、日志记录

日志分操作日志和错误日志，可以设置在数据库和文本中同时记录：

通过全局过滤器GlobalExceptionFilter和GlobalAuthorizeFilter处理

9、前端的封装（分页、弹出层、ajax等）

先放几张图吧，详细的以后再介绍
