Using properties in mule
- 2. PROPERTIES • A properties file is a simple collection of key-value pairs that can be parsed by the java.util.Properties class. They are often used to store configuration or localization data. In mule properties file can be configured using property placeholders and system properties. Property Placeholders: • Property placeholders allow you to upload the parameters from a properties file. This enables you, for example, to have different property files for different environments (Dev, QA, and Prod).
- 3. • It also allows you to reuse the same value in different parts of your configuration. • A very simple example shows how to use the property placeholders. • The values for these placeholders can be made available in a variety of ways, as described in the sections below.
- 4. Global Properties: You can use the <global-property> element to set a placeholder value from within your Mule configuration, such as from within another Mule configuration file that are configured as below:

- 7. • Where the contents of the test.properties is: • To load multiple properties files, separate them with commas:
- 8. Example: • The example above tries to display the property name which is a common property from various sources the observation is as below:
- 9. Observation: • The property in the mule-app.properties is prioritized the most, Global variables is prioritized the next most and next is the run time arguments followed by Environment Variables and then follows the property files in alphabetical order.
