Websharp应用系统的配置

1、 缓存的配置

Websharp使用了微软的Cached Application Block来缓存数据,因此,下面的缓存信息必须在应用程序中添加。关于Cached Application Block,可以参见微软的相关文档。

<configuration>

<configSections>

<section name="CacheManagerSettings" type="Microsoft.ApplicationBlocks.Cache.CacheConfigurationHandler,Microsoft.ApplicationBlocks.Cache" />

<section name="WebsharpExpirationPolicy" type="Websharp.Service.WebsharpCofigurationHandler,Websharp" />

</configSections>

<CacheManagerSettings>

<!-- DATA PROTECTION SETTINGS

Use DataProtectionInfo to set the assembly and class which implement

the dataprotection interfaces for the cache.

-->

<DataProtectionInfo AssemblyName="Microsoft.ApplicationBlocks.Cache"

ClassName="Microsoft.ApplicationBlocks.Cache.DataProtection.DefaultDataProtection"

ValidationKey="Oci44OQ9C3xAdQ3/BMHpksPfzeTezLkXen/ahQ8T7nVk/KMgAFnssQJr00KUNhRso+MpLVwAinGep6i14X9M+A=="

Validation="SHA1"/>

<!-- STORAGE SETTINGS

Use StorageInfo to set the assembly and class which implement

the storage interfaces for the cache.

Modes: InProc, OutProc

-->

<StorageInfo AssemblyName="Microsoft.ApplicationBlocks.Cache" ClassName="Microsoft.ApplicationBlocks.Cache.Storages.SingletonCacheStorage" Mode="InProc" Validated="true" Encrypted="true" RemotingUrl="tcp://localhost:8282/CacheService" />

<!--StorageInfo AssemblyName="Microsoft.ApplicationBlocks.Cache" ClassName="Microsoft.ApplicationBlocks.Cache.Storages.SqlServerCacheStorage" Mode="InProc" ConnectionString="user id=sa;password=msljkdv1;Network=DBMSSOCN;DATABASE=cacheab;SERVER=msljksrv02" Encrypted="true" Validated="true" ApplicationName="Sports" RemotingUrl="tcp://localhost:8282/CacheService" /-->

<!--<StorageInfo AssemblyName="Microsoft.ApplicationBlocks.Cache" ClassName="Microsoft.ApplicationBlocks.Cache.Storages.MmfCacheStorage" Mode="InProc" BasePath="c:\mmfcache\" Encrypted="true" Validated="true" MmfDictionarySize="1048576" RemotingUrl="tcp://localhost:8282/CacheService"/>-->

<!--

MmfDictionarySize - It is the size (in bytes) of the dictionary object (in MmfCacheStorage) used to store the references of cache items.

-->

<!-- SCAVENGING SETTINGS

Use the ScavengingAlgorithm to set a class that will be executed when

scavenging is performed.

-->

<ScavengingInfo AssemblyName="Microsoft.ApplicationBlocks.Cache" ClassName="Microsoft.ApplicationBlocks.Cache.Scavenging.LruScavenging" MemoryPollingPeriod="60" UtilizationForScavenging="80" MaximumSize="5"/>

<!-- EXPIRATION SETTINGS

Use the ExpirationCheckInterval to change the interval to check for

cache items expiration. The value attribute is represented in seconds.

-->

<ExpirationInfo Interval="1" />

</CacheManagerSettings>

<WebsharpExpirationPolicy>

<ExpirationPolicy ExpirationCheckInterval="60" AssemblyName="Microsoft.ApplicationBlocks.Cache" ClassName="Microsoft.ApplicationBlocks.Cache.ExpirationsImplementations.SlidingTime" />

</WebsharpExpirationPolicy>

</configuration>

2、 系统持久化配置信息

配置PersistenceProperty,对于Web应用系统,可以在Global.asax中配置,对于Windows应用程序,可以在程序初始化时设置。

下面是设置的一个例子:

PersistenceProperty pp=new PersistenceProperty();

pp.ConnectionString="server=127.0.0.1;uid=sa;pwd=;database=logisticsDemo;";//数据库连接字符串

pp.DatabaseType=DatabaseType.MSSQLServer; //数据库类型

pp.MapFileLocation=@"WebsharpTestLib,WebsharpTestLib.xml"; //XML定义文件的路径

pp.MapFileLocationTye=MapFileLocationType.Assembly; //XML文件路径的类型

pp.UserID="sa"; //数据库用户名,必须与数据库连接字符串中的用户名一致

pp.Password=""; //数据库用户密码,必须与数据库连接字符串中的用户密码一致

ApplicationConfiguration.DefaultPersistenceProperty=pp; //设置应用程序的默认配置属性

配置信息的说明如下:

1) 数据库连接字符串、用户名和密码的设置按照常规设置

2) MapFileLocationTye指明XML映射文件的路径类型,可以有三种类型:

a) AbsolutePath:采用绝对路径的形式,在这种情况下,MapFileLocation设置成绝对路径的形式,如:“d:\apppath\xml”。

b) VirtualPath:对于Web应用程序,可以设置为虚拟路径的形式,如“/MyWebApp/EntityDefinitions/”。

c) Assembly:XML文件作为资源文件被编译。采用这种形式,需要将XML文件的生成操作属性设置成“嵌入的资源”,这种情况下,MapFileLocation的格式为:“AssemblyName,NameSpace”。例如,XML文件位于WebsharpTestLib项目的xml文件夹下面,MapFileLocation可以设置为:“WebsharpTestLib,WebsharpTestLib.xml”
