如何添加新工件使用带有API的WSO2可配置治理工件

Question

我想添加一个使用API的WSO2可配置治理工件的新工件，编写的代码如下：

public static Registry getRegistry() {
            Registry governanceRegistry = null;
            String url = "https://localhost:9443/registry";
            String username = "admin";
            String password = "admin";
            System.setProperty("carbon.repo.write.mode", "true");
            try {
                RemoteRegistry rootRegistry = new RemoteRegistry(new URL(url), username,
                        password);
                governanceRegistry = GovernanceUtils.getGovernanceUserRegistry(
                        rootRegistry, username);
            } catch (RegistryException e) {
                e.printStackTrace();
            } catch (MalformedURLException e) {
                e.printStackTrace();
            }
            return governanceRegistry;
        }

    public static void main(String[] args) {
            try {
                Registry registry = WSRegistryClient.getRegistry();
                GovernanceUtils.loadGovernanceArtifacts((UserRegistry) registry);
                GenericArtifactManager artifactManager = new GenericArtifactManager(
                        registry, "endpoint");
                GenericArtifact artifact = artifactManager
                        .newGovernanceArtifact(new QName("http://www.example.com/", "endpoint_1"));
                artifact.setAttribute("Name", "endpoint");
                artifact.setAttribute("Version", "1.0.0");
                artifact.setAttribute("Address", "http://www.google.com");
                artifactManager.addGenericArtifact(artifact);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }

"端点"是这样退出工件类型：

<artifactType type="application/vnd.wso2-endpoint+xml" shortName="endpoint" singularLabel="Endpoint"
              pluralLabel="Endpoints" hasNamespace="false" iconSet="2">
    <storagePath>/trunk/endpoints/@{overview_name}</storagePath>
    <nameAttribute>overview_name</nameAttribute>
    <lifecycle>EndpointLifeCycle</lifecycle>
    <ui>
        <list>
            <column name="Name">
                <data type="path" value="overview_name" href="@{storagePath}"/>
            </column>
            <column name="Version">
                <data type="path" value="overview_version" href="@{storagePath}"/>
            </column>
        </list>
    </ui>
    <content>
        <table name="Overview">
            <field type="text" required="true" readonly="true">
                <name>Name</name>
            </field>
            <field type="text" required="true">
                <name>Version</name>
            </field>
            <field type="text" required="true">
                <name>Address</name>
            </field>
            <field type="text">
                <name>Environment</name>
            </field>
        </table>
    </content>
</artifactType>

我错过什么了吗？或者使用API的可配置治理工件有什么问题？提前感谢

通过查看您的代码，我认为您犯了一个小错误。请更改以下代码，

artifact.setAttribute("overview_name", "endpoint");
artifact.setAttribute("overview_version", "1.0.0");
artifact.setAttribute("overview_address", "http://www.google.com");

除了不使用快照版本外，请尽可能使用发布版本。

还有一种更简单的方法，您可以使用Governance REST API来添加工件。
