@Scanned
public class IssueCRUD extends HttpServlet{
    private static final Logger log = LoggerFactory.getLogger(IssueCRUD.class);

    @JiraImport
    private IssueService issueService;
    @JiraImport

the @Scanned cannot use and cannot import the jar

Without pom.xml we have no idea about how your plugin handles dependencies.

As far as I know, no Jira plugin requires @Scanned anotations, because everything is "@Scanned" automatically.

Lastly, you do not just "import" a dependency - you need to route it via a constructor.

If you stick with the atl. tutorials https://developer.atlassian.com/server/framework/atlassian-sdk/create-a-helloworld-plugin-project you will find how to structure it.

Sadly, those tutorials are largely outdated, do not match current SDK versions, so it's quite a frustration to get the ropes, but in majority the information there is correct, you're usually looking at differences between versions.

Thank you for your response, Firstly.In the develop ways,It is a little sad that those tutorials are largely outdated, do not match current SDK versions.

In some tutorials.I find the @Scanned cannot work well.

Here are my pom.xml

Alright, cool. Mostly I was looking for the spring scanner version, because most tutorials are built with 1.x even though 2.x is out for years.

Now, take the following with a grain of salt, this is just what I think:

The old '<atlassian.spring.scanner.version>' 1.x is pain and suffering, because you had to manually declare your Jira dependencies, which was both annoying, and made a disgusting clutter in the plugin's module list.

Since you have 2.x, we don't have to worry about it and we can just use any dependencies from Jira we need, and spring scanner will provide them to us.

So the following should be working:

public class TestConfigurationPage extends HttpServlet {

    @ComponentImport private final TemplateRenderer templateRenderer;
    private final AOManager aoManager;

    public TestConfigurationPage(TemplateRenderer templateRenderer, AOManager aoManager) {
        this.templateRenderer = templateRenderer;
        this.aoManager = aoManager;
    }

    //whatever other methods, doGet, doPost, etc.
}

This is where the spring scanner comes in. When we install the plugin, it will start instantiating our classes and it will be routing dependencies into constructors.

Note that the 'AOManager' is a class in this plugin, which is why it needs no annotation. Because of the dependency on it, AOManager will be initialized first, then TestConfigurationPage will be initialized after it, with the instance of AOManager being injected into it's constructor via spring.

The dependency from Jira is annotated with @ComponentImport - this is the same as @JiraImport in your example, but the difference is you can use the same annotation in Confluence as well (I think other atl. apps too, but not sure). This is what tells spring to get this from Jira and if Jira has such a thing, then spring will route it to the constructor.
