Text Java Properties Format

MIME type: text/x-java-properties

ID: properties

The Text Java Properties format parses any Java properties file. This format represents simple key-value pairs. DataWeave represents these pairs as an object with string values.

Example: Represent a properties File in the DataWeave Format (dw)

This example shows how DataWeave represents a properties file.

Input

The following text/x-java-properties data is from a properties file. The file contains key-value pairs that provide host and port values. This content serves as the input payload to the DataWeave script.

host=localhost
port=1234

Source

The DataWeave script transforms the text/x-java-properties input payload to the DataWeave (dw) format and MIME type. It returns a string.

%dw 2.0
output application/dw
---
payload

Output

The output is an object in the DataWeave (dw) format. The object contains a collection of key-value pairs that match the text/x-java-properties input. Notice that the output wraps the values in quotation marks.

{
    host: "localhost",
    port: "1234"
}
