Maven users will need to add the following dependency to their pom.xml

<artifactId>camel-stringtemplate</artifactId>
<version>x.x.x</version>
<!-- use the same version as your Camel core version -->
</dependency>

{div:class=confluenceTableSmall}
|| key || value ||
| {{exchange}} | The Exchange itself. |
| {{headers}} | The headers of the In message. |
| {{camelContext}} | The Camel Context. |
| {{request}} | The In message. |
| {{in}} | The In message. |
| {{body}} | The In message body. |

Since Camel 2.14, you can define the custom context map by setting the message header "CamelStringTemplateVariableMap" just like the below code.
Code Block |
---|
|
Map<String, Object> variableMap = new HashMap<String, Object>();
Map<String, Object> headersMap = new HashMap<String, Object>();
headersMap.put("name", "Willem");
variableMap.put("headers", headersMap);
variableMap.put("body", "Monday");
variableMap.put("exchange", exchange);
exchange.getIn().setHeader("CamelStringTemplateVariableMap", variableMap);

Samples
For example you could use a string template as follows in order to formulate a response to a message:
Code Block |

...
In this sample we want to use a string template to send an order confirmation email. The email template is laid out in StringTemplate
