Jira插件开发如何获取RapidViewServiceImpl实例

Question

我正在使用 Java 开发 Jira 报告插件，我需要获取 RapidViewServiceImpl class 的实例。如果我使用构造函数，我会得到一个 nullPtrException 并且我认为还有另一种方法来获取这个实例。例如，我对 SprintManager 和 SprintManagerImpl 有完全相同的问题，我得到的实例如下：

private com.atlassian.greenhopper.service.sprint.SprintManager getSprintManager() throws InvalidSyntaxException {   
    ApplicationContext appCtx = (ApplicationContext) getGreenHopperAppCtx();
    if (appCtx != null) {
        return (com.atlassian.greenhopper.service.sprint.SprintManager) appCtx.getBean("sprintManagerImpl");
    }
    return null;
}

private Object getGreenHopperAppCtx() throws InvalidSyntaxException {
    OsgiContainerManager osgi = ComponentAccessor.getComponentOfType(OsgiContainerManager.class);
    if (osgi == null) {
        java.lang.System.out.println("OSGI Not Found");
        return null;
    }    
    Bundle[] bundles = osgi.getBundles();        
    for (int i = 0; i < bundles.length; i++) {
        Bundle bundle = bundles[i];    
        if ("com.pyxis.greenhopper.jira".equals(bundle.getSymbolicName())) {

            BundleContext bctx = bundle.getBundleContext();
            ServiceReference[] refs = bctx.getAllServiceReferences(null, null);
            if (refs != null) {
                for (int j = 0; j < refs.length; j++) {
                    Object prop = refs[j].getProperty("org.springframework.context.service.name");
                    if ("com.pyxis.greenhopper.jira".equals(prop)) {
                        return bctx.getService(refs[j]);
                    }
                }
            }
        }
    }
    return null;
}

在主函数中我调用了SprintManager spManager = getSprintManager()。我用 RapidViewServiceImpl:

尝试了同样的事情

private Object getGreenHopperAppCtx() throws InvalidSyntaxException {
    OsgiContainerManager osgi = ComponentAccessor.getComponentOfType(OsgiContainerManager.class);
    if (osgi == null) {
        java.lang.System.out.println("OSGI Not Found");
        return null;
    }    
    Bundle[] bundles = osgi.getBundles();        
    for (int i = 0; i < bundles.length; i++) {
        Bundle bundle = bundles[i];    
        if ("com.pyxis.greenhopper.jira".equals(bundle.getSymbolicName())) {

            BundleContext bctx = bundle.getBundleContext();
            ServiceReference[] refs = bctx.getAllServiceReferences(null, null);
            if (refs != null) {
                for (int j = 0; j < refs.length; j++) {
                    Object prop = refs[j].getProperty("org.springframework.context.service.name");
                    if ("com.pyxis.greenhopper.jira".equals(prop)) {
                        return bctx.getService(refs[j]);
                    }    
                }
            }
        }
    }
    return null;
}    
//------------------------------------------------------------------------------------------------------------------
private com.atlassian.greenhopper.service.rapid.view.RapidViewService getRapidViewManager() throws InvalidSyntaxException {    
    ApplicationContext appCtx = (ApplicationContext) getGreenHopperAppCtx();
    if (appCtx != null) {
        return (RapidViewService) appCtx.getBean("rapidViewService");
    }
    return null;
}

但是我收到一条错误消息，提示没有名为“rapidViewService”的包。这是错误的一部分，我无法 post 整个错误，因为它太长了：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'rapidViewService' is defined

有人可以帮我解决这个问题吗？

Answer 1

我使用 class ProjectRapidViewServiceImpl 解决了这个问题，并且我使用名为 "projectRapidViewServiceImpl"

的包获得了这个 class 的实例

private com.atlassian.greenhopper.service.rapid.ProjectRapidViewService getRapidViewManager() throws InvalidSyntaxException {    
    ApplicationContext appCtx = (ApplicationContext) getGreenHopperAppCtx();
    if (appCtx != null) {
        return (ProjectRapidViewServiceImpl) appCtx.getBean("projectRapidViewServiceImpl");
    }
    return null;
}

并且这个 class 有一个名为 findRapidViewsByProject(com.atlassian.jira.user.ApplicationUser user, com.atlassian.jira.project.Project project) 的函数，其中 returns 一个与项目相关的 RapidViews 列表。
