From Camel 2.8 you can configure the result type of the Simple expression. The examples listed below are hosted at Apache.
${properties:com/mycompany/bar.properties:bar.quote}. Boolean. Configuring result type From Camel 2.8 onwards you can configure the result type of the Simple expression. First we have the Blueprint XML file:The Spring Framework does not allow third-party frameworks such as Apache Camel to seamless hook into the Spring property placeholder mechanism. You can define a spring bean as a Setting the properties location through the location tag works just fine but sometime you have a number of resources to take into account and starting from For example in OSGi you may want to expose a service which returns the properties as a When using property placeholders in the endpoint URIs you can either use the You can also use placeholders as a part of the endpoint URI:In the example above the to endpoint will be resolved to You can also have properties with refer to each other such as:You can also your property placeholders when using The property placeholders is also supported in many of the Camel Spring XML tags such as Example using property placeholders in the attributes of If you use OSGi Blueprint then this only works from In our properties file we have the value defined as:Likewise we have added support for defining placeholders in the Java DSL using the new By default Camel detects and uses OSGi blueprint property placeholder service. This works much like you would do if using Spring's tag. Export to Word The following examples show how to use org.apache.camel.component.properties.PropertiesComponent.These examples are extracted from open source projects. First we have the Blueprint XML file:The Spring Framework does not allow third-party frameworks such as Apache Camel to seamless hook into the Spring property placeholder mechanism. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. Export to EPUB Sets the class name of the result type (type from output) trim. Here is a complete example. Using PropertyPlaceholder Available as of Camel 2.3. You can define a spring bean as a When using property placeholders in the endpoint URIs you can either use the You can also use placeholders as a part of the endpoint uri:In the example above the to endpoint will be resolved to You can also have properties with refer to each other such as:You can also use property placeholders directly in the endpoint uris without having to use And you can use them in multiple wherever you want them:You can also your property placeholders when using The property placeholders is also supported in many of the Camel Spring XML tags such as The example below has property placeholder in the tag:You can also define property placeholders in the various attributes on the tag such as In our properties file we have the value defined asLikewise we have added support for defining placeholders in the Java DSL using the new By default Camel detects and uses OSGi blueprint property placeholder service. For that you need to use the Camel's When using Blueprint property placeholder in the Blueprint XML file, you can declare the properties directly in the XML file as shown below:Now if you want to override these Blueprint properties from an unit test, you can do this as shown below:When using Blueprint property placeholder in the Blueprint XML file, you can declare the properties in a .properties or You can do both as well. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example.

This can be used in situations to avoid clashes when using for example Spring property placeholder together with Camel. From Camel 2.3 onwards there is a Properties component build in Camel core which allows you to use properties in the same way as Spring property placeholders, and even more. Setting the properties location through the location tag works just fine but sometime you have a number of resources to take into account and starting from  you can set the properties location with a dedicated By default Camel detects and uses OSGi blueprint property placeholder service. This can be used in situations to avoid clashes when using for example Spring property placeholder together with Camel. As they are provided out of the box, they can easily be used as shown below:You can use default values as well, so if the property does not exists, you can define a default value as shown below, where the default value is a The service function is for looking up a service which is defined using OS environment variables using the service naming idiom, to refer to a service location using And we can use default values if the service has not been defined, for example to call a service on localhost, maybe for unit testing etc:Here we have a Camel XML route where we have defined the The implementation of the function is only two methods as shown below:To register a custom function from Java code is as shown below:
