# ASP.Net 6

## 1. 部署到Docker

### 1.1 安装.Net SDK 6.0环境

```shell
sudo rpm -Uvh https://packages.microsoft.com/config/centos/7/packages-microsoft-prod.rpm
sudo yum install dotnet-sdk-6.0
dotnet --info
```

### 1.2 Visual Studio添加Docker支持

### 1.3 Linux下构建Docker镜像

```shell
docker image build -f ./XiaodaERP/Dockerfile -t aspnetcore .
docker images
```

### 1.4 运行Docker镜像

```shell
docker run --name=aspnetcore -p 9001:80 -d aspnetcore
docker ps
```



```shell
cd /usr/local/jenkins_home/workspace/XiaodaERP_NetCore
echo $PWD
docker image build -f ./XiaodaERP/Dockerfile -t xiaodaerp/netcore .
docker images 
docker run --name xiaodaerp/netcore -p 7274:80 -d xiaodaerp/netcore
```

## 2. 顶级语句配置`Program.cs`

### 2.1 取消默认JSON首字母小写命名

```c#
builder.Services.AddControllers().AddJsonOptions(options => {
    options.JsonSerializerOptions.PropertyNamingPolicy = null;
});
```

### 2.2 Json序列化时忽略属性为null的值

```c#
builder.Services.AddControllers().AddJsonOptions(options => {
    options.JsonSerializerOptions.DefaultIgnoreCondition = JsonIgnoreCondition.WhenWritingNull;
});
```

### 2.3 使用Autofac自动注入Service

通过NuGet包管理器 安装NuGet包

Autofac

Autofac.Extensions.DependencyInjection

Autofac.Extras.DynamicProxy

新建`ServiceAutofac.cs`类

```c#
using System.Reflection;

namespace XiaodaERP
{
    public class ServiceAutofac
    {
        /// <summary>
        /// 获取程序集名称
        /// </summary>
        /// <returns></returns>
        public static string GetAssemblyName()
        {
            return Assembly.GetExecutingAssembly().GetName().Name;
        }
    }
}
```

`Program.cs`配置

```c#
builder.Host.UseServiceProviderFactory(new AutofacServiceProviderFactory());
builder.Host.ConfigureContainer<ContainerBuilder>(builder =>
{
    Assembly assembly = Assembly.Load(ServiceAutofac.GetAssemblyName());//注入Service程序集 可以是其他程序集
    builder.RegisterAssemblyTypes(assembly)
    .AsImplementedInterfaces()
    .InstancePerDependency();
});
```

### 2.4 注入Entity Framework Core 6 DbContext上下文

```c#
builder.Services.AddDbContext<OracleDbContext>(options =>
options.UseOracle(builder.Configuration.GetConnectionString("OracleDbContext")));

builder.Services.AddDbContext<SqlServerDbContext>(options =>     			  options.UseSqlServer(builder.Configuration.GetConnectionString("SqlServerDbContext")));
```
