Functionality

This package analyzes your project's classpath and parses and indexes any Spring Boot Properties Metadata it finds. Both Maven and Gradle projects are supported.

The data in the index is used to provide validation, code completions and information hovers while editing Spring Boot Properties in either .properties or .yml format.

Validation

Property keys as well as property values are validated. Property keys are validated for being known properties and values are checked for being of expected type as well being a valid value

Code Completions

Both YAML and Properties formats have support for Content Assist on property keys and values helping to write valid Spring Boot configuration files right from the start.

Information Hovers

Hovering over property keys provide valuable documentation about the purpose of the property and expected type for its value in a small popup window.
