Spring version : 2.0.0.40000
Runtime : .NET 4.5
Taking the example shown here
www.springframework.net/.../objects.html and in the API
http://springframework.net/docs/1.3..../webframe.html - ContextHandler
I have the following
Code:
<configSections>
<sectionGroup name="spring">
<section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core"/>
<section name="objects" type="Spring.Context.Support.DefaultSectionHandler, Spring.Core" />
<sectionGroup name="child">
<section name="objects" type="Spring.Context.Support.DefaultSectionHandler, Spring.Core"/>
</sectionGroup>
</sectionGroup>
</configSections>
<spring>
<objects xmlns="http://www.springframework.net">
<import resource="assembly://ProjectDLL/Config/Spring.xml"/>
</objects>
<child>
<objects xmlns="http://www.springframework.net">
<object name="eventLog"
type="System.Diagnostics.EventLog, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
>
<constructor-arg type="string" name="logName" value="v1" />
<constructor-arg type="string" name="machineName" value="." />
<constructor-arg type="string" name="source" value="v1" />
</object>
</objects>
</child>
<context name="Parent">
<resource uri="config://spring/objects"/>
<context name="child">
<resource uri="config://spring/child/objects"/>
</context>
</context>
</spring>
Calling
ContextRegistry.GetContext();
of any context names results in
Message --- Error creating context 'ChildContext': Errored while postprocessing an object factory.
I've tried all the various naming for including Child, ChildContext, Children, all resulting in the same error.
In my example, I use a resource file that contains my objects ( ), if I do not import my own XML file, it works but importing it means that the child does not work. If I define the child in the same xml file, I get "Error creating context 'Parent': There are multiple root elements"
I know this is most likely a configuration issue and would appreciate any help.
Having not fully understood the error I was getting or why, the workaround was to use "depends-on" for startup. The spring xsd defines quiet a few here http://www.springframework.net/xsd/spring-objects.xsd

I want to eventually set up Paypal payment. Step one though is to have a play. And I have failed on the quick start!
https://github.com/paypal/PayPal-NET-SDK/wiki/Quick-Start shows a code example. It explains that first, I need to download the PayPal .NET SDK package via NuGet. This is great, I'm on .NET Framework (not core). I install it.
Phase 2 gives an entire example. I add some PayPal config settings to the app.config file. Done
Phase 3 is where it is going wrong. I'm referencing PayPal.API in my C# class.
The relevant part of my code is
using PayPal.Api;
using System.Collections.Generic;
namespace TestProj.Payment
{
public class PaypalGateway
{
public void Sandbox()
{
var config = ConfigManager.Instance.GetProperties();// this is the fault
var accessToken = new OAuthTokenCredential(config).GetAccessToken();
config always has 0 instances
My Project has an App.config file with the correct values
<configSections>
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
<section name="paypal" type="PayPal.SDKConfigHandler, PayPal" />
</configSections>
<paypal>
<settings>
<add name="mode" value="sandbox" />
<add name="clientId" value="***" />
<add name="clientSecret" value="***" />
</settings>
</paypal>
If I rename my App.config file to blah.nonsense then the same issue occurs. It's as if the API is looking for a file else where or that it isn't configured correctly.
This question is tagged with asp.net-mvc, so the assumption is that this is for a web project
The quick start clearly states
Add the following to your web.config or app.config
web.config should where you place the configuration details if this is in fact a web project.
Even if the referenced code is for another class library in the project, which can use app.config file, all the settings will eventually have to be in the root web.config file of the web project as that is the process that will be running.
the same problem was with me, the keyword PayPal must be in small caps like paypal.
<configSections>
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
<section name="paypal" type="PayPal.SDKConfigHandler, **PayPal**" />
</configSections>
<paypal>
<settings>
<add name="mode" value="sandbox" />
<add name="clientId" value="***" />
<add name="clientSecret" value="***" />
</settings>
</paypal>
should be
<configSections>
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
<section name="paypal" type="PayPal.SDKConfigHandler, **paypal**" />
</configSections>
<paypal>
<settings>
<add name="mode" value="sandbox" />
<add name="clientId" value="***" />
<add name="clientSecret" value="***" />
</settings>
</paypal>
Could anyone please help me take a look at this issue since I can only create a Spring object type String? When I try to create another Spring object type, I get the below error
Error

See also: How do I create a spring .Net standalone object of type Int32 defined in the IOC context file?
You can create an object with all your configuration and then just inject it:
<object id="ServerConfig" type"...">
<property name="ServerPort" value="5222"/>
...
</object>
<object id="Server" type"...">
<!-- Constructor injection -->
<constructor-arg name="configuration" ref="ServerConfig"/>
<!-- OR Property injection -->
<property name="Configuration" ref="ServerConfig"/>
</object>
Is it possible to split the configuration for an enterprise library block into multiple files?
For example: I have three assemblies and one hosting project. I want to store the entlib v6 Exception Handling Application Block (EHAB) configuration for each assembly in a separate config file located in the particular assembly.
The hosting project references the three assemblies:
assembly_X
ehabX.config
assembly_Y
ehabY.config
assembly_Z
ehabZ.config
Hosting project
using ehabX.config
using ehabY.config
using ehabZ.config
I already tried the following:
App.config in the hosting project:
<?xml version="1.0"?>
<configuration>
<configSections>
<section name="enterpriseLibrary.ConfigurationSource" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ConfigurationSourceSection, Microsoft.Practices.EnterpriseLibrary.Common" requirePermission="true" />
</configSections>
<enterpriseLibrary.ConfigurationSource>
<sources>
<add name="ehabX" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.FileConfigurationSource, Microsoft.Practices.EnterpriseLibrary.Common" filePath="ExceptionHandling\ehabX.config" />
<add name="ehabY" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.FileConfigurationSource, Microsoft.Practices.EnterpriseLibrary.Common" filePath="ExceptionHandling\ehabY.config" />
<add name="ehabZ" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.FileConfigurationSource, Microsoft.Practices.EnterpriseLibrary.Common" filePath="ExceptionHandling\ehabZ.config" />
</sources>
<redirectSections>
<add sourceName="ehabX" name="exceptionHandling" />
<add sourceName="ehabY" name="exceptionHandling" />
<add sourceName="ehabZ" name="exceptionHandling" />
</redirectSections>
</enterpriseLibrary.ConfigurationSource>
</configuration>
ehabX.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="exceptionHandling" type="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Configuration.ExceptionHandlingSettings, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling"/>
</configSections>
<exceptionHandling>
<exceptionPolicies>
<add name="Swallow NotImplementedException">
<exceptionTypes>
<add type="System.NotImplementedException, mscorlib" postHandlingAction="None" name="NotImplementedException"/>
</exceptionTypes>
</add>
</exceptionPolicies>
</exceptionHandling>
</configuration>
ehabY.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="exceptionHandling" type="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Configuration.ExceptionHandlingSettings, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling"/>
</configSections>
<exceptionHandling>
<exceptionPolicies>
<add name="Swallow ArgumentException">
<exceptionTypes>
<add type="System.ArgumentException, mscorlib" postHandlingAction="None" name="NotImplementedException"/>
</exceptionTypes>
</add>
</exceptionPolicies>
</exceptionHandling>
</configuration>
The ehabZ.config is omitted.
Using the EHAB with the policy "Swallow NotImplementedException" works fine. But if I try to use the policy "Swallow ArgumentException" defnied in ehabY.config I get this error message:
Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.ExceptionHandlingException: The policy with name 'Swallow ArgumentException' cannot be found. Exception handling aborted.
Any suggestions?
Unfortunately, there is nothing out of the box that will let you merge multiple configuration sources into one configuration set.
I think you can probably do what you want but you will have to do some coding. You'll need to read in the appropriate configuration sources and create a custom IConfigurationSource that will merge them all. Additive merge of different config sources? has an example of a MergeConfigurationSource that could help you.
I have Web.config:
<?xml version="1.0"?>
<configuration>
<configSections>
<section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate" requirePermission="false"/>
</configSections>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
<session-factory>
<property name="connection.driver_class">NHibernate.Driver.OracleClientDriver</property>
<property name="connection.connection_string">{old_connection}</property>
<property name="dialect">NHibernate.Dialect.Oracle10gDialect</property>
<property name="proxyfactory.factory_class">NHibernate.Bytecode.DefaultProxyFactoryFactory, NHibernate</property>
<property name="show_sql">false</property>
<property name="query.substitutions">true 1, false 0, yes 'Y', no 'N'</property>
</session-factory>
</hibernate-configuration>
</configuration>
I apply a transformation. Web.Release.config:
<?xml version="1.0" encoding="utf-8"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform"
xmlns:hib="urn:nhibernate-configuration-2.2">
<configSections>
<section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate" requirePermission="false"/>
</configSections>
<hib:hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
<hib:session-factory>
<hib:property xdt:Transform="Replace" xdt:Locator="Match(name)" name="connection.connection_string">{new_connection}</hib:property>
</hib:session-factory>
</hib:hibernate-configuration>
</configuration>
Run in VS2012 in Release, the transformation does not occur. The string is not replaced.
In what could be the reason?
The transformation does not happen because the element names differs from your baseline Web.config. If you remove the hib namespace, transformation will take place.
<?xml version="1.0" encoding="utf-8"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
<session-factory>
<property xdt:Transform="Replace" xdt:Locator="Match(name)" name="connection.connection_string">{new_connection}</property>
</session-factory>
</hibernate-configuration>
</configuration>
Another thing to note. If your current configuration is Release and you are running your application through Visual Studio, the server will point to the root of your project. In the root, you will have Web.config, Web.Debug.config and Web.Release.config and the server will pick-up the usual configuration file, without the transformation (ie Web.config).
I have a console application that loads other libraries (DLL's). I'm using Spring.NET. My console application is very simple, load the app.config that is configured through DI to initialize the chosen library.
Code
ContextRegistry.GetContext();
Configuration (app.config)
<?xml version="1.0"?>
<configuration>
<configSections>
<sectionGroup name="spring">
<section name="context"
type="Spring.Context.Support.ContextHandler, Spring.Core"/>
<section name="objects"
type="Spring.Context.Support.DefaultSectionHandler, Spring.Core"/>
</sectionGroup>
</configSections>
<spring>
<context>
<resource uri="config://spring/objects"/>
<resource uri="assembly://MyDLL/MyDLL.Config/Services.xml"/>
</context>
<objects xmlns="http://www.springframework.net"
xmlns:aop="http://www.springframework.net/aop">
</objects>
</spring>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup></configuration>
Each library has its own "services.xml" file. These libraries also use Spring.NET.
<objects xmlns="http://www.springframework.net"
xmlns:aop="http://www.springframework.net/aop">
<object id="componentObj"
type="MyDLL.Services.ComponentService, MyDLL"
singleton="true" />
<object
id="componentServiceHost"
type="Spring.ServiceModel.Activation.ServiceHostFactoryObject, Spring.Services">
<property name="TargetName"
value="componentObj" />
</object>
</objects>
Getting a excpetion "Process is terminated due to StackOverflowException." If I comment out the <object id="componentServiceHost", the exception does not occur.
The VS console in debug shows
A first chance exception of type 'System.InvalidOperationException' occurred in System.ServiceModel.dll
A first chance exception of type 'Spring.Objects.Factory.ObjectCreationException' occurred in Spring.Core.dll
A first chance exception of type 'Spring.Objects.Factory.ObjectCreationException' occurred in Spring.Core.dll
Managed (v4.0.30319)' has exited with code -2147023895 (0x800703e9).
You can also place spring configuration in plain xml files and include those with your library. This way, you can easily share this configuration without the need of sharing an app.config.
You do have to explicitly reference this configuration file in the configuration of your host console application, but that's no duplication. The app.config of your console application host will look like this:
...
<spring>
<context>
<resource uri="file://services.xml"/>
<resource uri="assembly://MyAssembly/MyDataAccess/data-access.xml"/>
</context>
</spring>
See the spring.net docs how to configure a configuration in xml.
