ManifestArtifactResourceResolver

Type: Class | Module: microsphere-java-core | Package: io.microsphere.classloading | Since: 1.0.0

Source: microsphere-java-core/src/main/java/io/microsphere/classloading/ManifestArtifactResourceResolver.java

Overview

ArtifactResourceResolver implementation that reads artifact metadata from JAR manifest files.

This resolver looks for artifact information in the META-INF/MANIFEST.MF file of a JAR or directory. It extracts the artifact ID and version using configurable manifest attributes.

Configuration Options

You can customize which manifest attributes are used to extract the artifact ID and version by setting system properties:

• #ARTIFACT_ID_ATTRIBUTE_NAMES_PROPERTY_NAME: A comma-separated list of attribute names to use for extracting the artifact ID. Default: #DEFAULT_ARTIFACT_ID_ATTRIBUTE_NAMES_PROPERTY_VALUE
• #VERSION_ATTRIBUTE_NAMES_PROPERTY_NAME: A comma-separated list of attribute names to use for extracting the artifact version. Default: #DEFAULT_VERSION_ATTRIBUTE_NAMES_PROPERTY_VALUE

Example Usage

`// Using default priority
ArtifactResourceResolver resolver = new ManifestArtifactResourceResolver();

// With custom priority
ArtifactResourceResolver resolver = new ManifestArtifactResourceResolver(10);

// With custom class loader and priority
ArtifactResourceResolver resolver = new ManifestArtifactResourceResolver(getClass().getClassLoader(), 10);
 `

Manifest Attribute Examples

The resolver will look at standard and custom manifest attributes. Here's an example MANIFEST.MF:

`Manifest-Version: 1.0
Bundle-Name: my-artifact
Bundle-Version: 1.2.3
Implementation-Title: my-artifact
Implementation-Version: 1.2.3
Automatic-Module-Name: com.example.myartifact
 `

In this case, the resolver would extract:

• Artifact ID: "my-artifact" (from Bundle-Name)
• Version: "1.2.3" (from Bundle-Version)

Declaration

public class ManifestArtifactResourceResolver extends StreamArtifactResourceResolver
