Operare su progetti Maven usando Spring Roo

Mer, 27/05/2009 - 16:09 — enrico

Appunti per operare programmaticamente su un progetto Maven, sfruttando le classi contenute in Spring Roo.

Ottenuto Spring Roo installare le librerie che servono dalla directory /dist/.

mvn install:install-file -Dfile=spring-roo-metadata-1.0.0.M1.jar \
 -DgroupId=org.springframework.roo -DartifactId=spring-roo-metadata \
 -Dversion=1.0.0.M1 -Dpackaging=jar -DgeneratePom=true
mvn install:install-file -Dfile=spring-roo-support-1.0.0.M1.jar \
 -DgroupId=org.springframework.roo -DartifactId=spring-roo-support \
 -Dversion=1.0.0.M1 -Dpackaging=jar -DgeneratePom=true
mvn install:install-file -Dfile=spring-roo-process-manager-1.0.0.M1.jar \
 -DgroupId=org.springframework.roo -DartifactId=spring-roo-process-manager \
 -Dversion=1.0.0.M1 -Dpackaging=jar -DgeneratePom=true
mvn install:install-file -Dfile=spring-roo-project-1.0.0.M1.jar \
 -DgroupId=org.springframework.roo -DartifactId=spring-roo-project \
 -Dversion=1.0.0.M1 -Dpackaging=jar -DgeneratePom=true

Aggiungere le necessarie dipendenze al progetto

        <dependency>
            <groupId>org.springframework.roo</groupId>
            <artifactId>spring-roo-process-manager</artifactId>
            <version>${roo.version}</version>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.roo</groupId>
            <artifactId>spring-roo-project</artifactId>
            <version>${roo.version}</version>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.roo</groupId>
            <artifactId>spring-roo-metadata</artifactId>
            <version>${roo.version}</version>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.roo</groupId>
            <artifactId>spring-roo-support</artifactId>
            <version>${roo.version}</version>
            <scope>provided</scope>
        </dependency>

Ora è possibile :

Verificare che una dipendenza sia installabile

public boolean isInstallSiteMeshAvailable() {
    Dependency dependency = new Dependency("opensymphony", "sitemesh", "2.4.2");
    ProjectMetadata project = (ProjectMetadata) metadataService.get(ProjectMetadata.getProjectIdentifier());
    if (project == null) {
        return false;
    }
    return project.getDependenciesExcludingVersion(dependency).size() == 0;
}

Aggiungere la dipendenza

ProjectOperations projectOperations = new ProjectOperations( /* MetadataService */ metadataService,
                                                              /* ProjectMetadataProvider */ projectMetadataProvider )
projectOperations.dependencyUpdate(/* Dependency */ dependency);

Scrivere il file web.xml

String webXml = pathResolver.getIdentifier(Path.SRC_MAIN_WEBAPP, "WEB-INF/web.xml");
 
MutableFile mutableWebXml = null;
Document webXmlDoc;
try {
    if (fileManager.exists(webXml)) {
        mutableWebXml = fileManager.updateFile(webXml);
        webXmlDoc = XmlUtils.getDocumentBuilder().parse(mutableWebXml.getInputStream());
    } else {
        throw new IllegalStateException("Could not acquire " + webXml);
    }
} catch (Exception e) {
    throw new IllegalStateException(e);
}
 
Element root = (Element) webXmlDoc.getFirstChild();
 
Element filter = webXmlDoc.createElement("filter");
Element filterName = webXmlDoc.createElement("filter-name");
filterName.setTextContent("sitemesh");
Element filterClass = webXmlDoc.createElement("filter-class");
filterClass.setTextContent("com.opensymphony.sitemesh.webapp.SiteMeshFilter");
filter.appendChild(filterName);
filter.appendChild(filterClass);
 
Element filterMapping = webXmlDoc.createElement("filter-mapping");
Element urlPattern = webXmlDoc.createElement("url-pattern");
Element filterName2 = webXmlDoc.createElement("filter-name");
filterName2.setTextContent("sitemesh");
urlPattern.setTextContent("/*");
filterMapping.appendChild(filterName2);
filterMapping.appendChild(urlPattern);
 
Element listener = XmlUtils.findRequiredElement("//listener", root);
Assert.notNull(listener, "Could not find the first listener element in web.xml");
listener.getParentNode().insertBefore(filter, listener);
listener.getParentNode().insertBefore(filterMapping, listener);
 
XmlUtils.writeXml(mutableWebXml.getOutputStream(), webXmlDoc);
