java - 扩展 JIRA 中现有的组件类

Question

我正在为 Jira 6.3 编写插件。
我想扩展 Jira 的接口(interface)com.atlassian.jira.bc.issue.attachment.AttachmentService:

public interface MyAttachmentService extend AttachmentService {
    ...
}

然后我实现了我的接口(interface):

public class MyDefaultAttachmentService extends DefaultAttachmentService implements MyAttachmentService {
    ...
}

我将我的类定义为 atlassian-plugin.xml 中的一个组件:

<component key="myAttachmentService" name="MyAttachmentService" class="com.my.plugin.issue.attachment.MyDefaultAttachmentService">
    <interface>com.my.plugin.issue.attachment.MyAttachmentService</interface>
</component>

这是我如何使用我的插件类(依赖注入(inject)):

public class DoSomethingWithAttachmentAction extends AbstractIssueSelectAction 
{
    private final MyAttachmentService myAttachmentService ;

    public DoSomethingWithAttachmentAction(MyAttachmentService myAttachmentService) {
        this.myAttachmentService = myAttachmentService;
    }

    public String doExecute() {
        myAttachmentService.someMethod();
    }
}

但是我在运行时遇到了以下错误:

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type [com.atlassian.jira.bc.issue.attachment.AttachmentService] is defined: expected single matching bean but found 2: [attachmentService, myAttachmentService]
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.resolveDependency(DefaultListableBeanFactory.java:621)
    ...

如何修复它并使用我的新组件？

Answer 1

也尝试使用 component-import 并说明要使用哪个接口(interface) - MyAttachmentService ，这应该配置 spring ioc
