Spring Rewrite Commons provides a set of components to parse a Java project to https://github.com/openrewrite[OpenRewrite,window=_blank] LST and apply recipes outside a build tool plugin.
== Get started
=== Add Dependency
=== Implement a Recipe Launcher
[source,java] .... package com.acme.example;
import org.openrewrite.Recipe; import org.openrewrite.SourceFile; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.rewrite.RewriteProjectParser; import org.springframework.rewrite.parser.RewriteProjectParsingResult; import org.springframework.rewrite.resource.ProjectResourceSet; import org.springframework.rewrite.resource.ProjectResourceSetFactory; import org.springframework.rewrite.resource.ProjectResourceSetSerializer; import org.springframework.rewrite.RewriteRecipeDiscovery; import org.springframework.stereotype.Component;
import java.nio.file.Path;
@Component public class MyMigrationApplication {
@Autowired <1>
private RewriteProjectParser parser;
@Autowired
private RewriteRecipeDiscovery discovery; <2>
@Autowired
private ProjectResourceSetFactory resourceSetFactory;
@Autowired
private ProjectResourceSetSerializer serializer;
public void migrateToBoot3_1() {
Path baseDir = Path.of("."); <2>
String recipeName = "org.openrewrite.java.spring.boot3.UpgradeSpringBoot_3_1";
Recipe boot3Upgrade = discovery.getByName(recipeName); <3>
RewriteProjectParsingResult result = parser.parse(baseDir); <4>
List<SourceFile> lst = result.sourceFiles(); <5>
ProjectResourceSet resourceSet = resourceSetFactory.create(baseDir, lst); <6>
resourceSet.apply(boot3Upgrade); <7>
serializer.writeChanges(resourceSet); <8>
}
}
....
<1> All components are Spring beans and can be injected as such.
<2> The path of the project that should be migrated.
<3> RewriteRecipeDiscovery
is used to discover an OpenRewrite recipe by name.
<4> RewriteProjectParser
parses a given project to OpenRewrite LST.
<5> The result contains the list of SourceFile
s (the LST).
<6> ProjectResourceSetFactory
can be used to create a ProjectResourceSet
.
<7> The recipe is applied to the ProjectResourceSet
which wraps the LST.
<8> ProjectResourceSetSerializer
is used to serialize the changes to disk.
