How do you trigger a java class to execute when a web item is clicked?
To simply activate some java code directly from a web-item, you can either bind it to a webwork action or a servlet.
Here is a servlet example:
<web-item name="Button" i18n-name-key="button.name" key="button-key"
section="your.section.in.jira" weight="1000">
<description key="desckey">This button activates some java</description>
<label key="button.label"/>
<link linkId="button-item">/jira/plugins/servlet/myservlet?issueKey=$issue</link>
<context-provider class="io.aety.jira.webwork.RequestContextProvider"/>
</web-item>
<servlet name="My Java Servlet" i18n-name-key="servlet.name" key="servlet-key"
class="io.aety.servlet.MyJavaClass">
<description key="servlet.description">This servlet can do java stuff</description>
<url-pattern>/myservlet</url-pattern>
</servlet>
Then add your java class, which you should put in (this example) at io.aety.servlet.MyJavaClass, here this class simply adds a vote to the issue.
@Scanned
public class MyJavaClass extends HttpServlet{
private static final Logger log = LoggerFactory.getLogger(PublicCustomerVote.class);
@JiraImport
private IssueService issueService;
@JiraImport
private ProjectService projectService;
@JiraImport
private SearchService searchService;
@JiraImport
private JiraAuthenticationContext authenticationContext;
@JiraImport
private ConstantsManager constantsManager;
public MyJavaClass(IssueService issueService, ProjectService projectService,
SearchService searchService,
JiraAuthenticationContext authenticationContext,
ConstantsManager constantsManager) {
this.issueService = issueService;
this.projectService = projectService;
this.searchService = searchService;
this.authenticationContext = authenticationContext;
this.constantsManager = constantsManager;
}
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException
{
//Get issue
IssueManager issueManager = ComponentAccessor.getIssueManager();
String issueKey = req.getParameter("issueKey");
Issue issue = issueManager.getIssueByCurrentKey(issueKey);
ComponentAccessor.getVoteManager().addVote(authenticationContext.getLoggedInUser(),currentIssue);
resp.setContentType("text/html");
resp.getWriter().write("<html><body>You ("+authenticationContext.getLoggedInUser().getUsername()+")" +
"voted for issue "+issueKey+"!</body></html>");
}
}
In your context provider (in this example located at io.aety.jira.webwork.RequestContextProvider) for the web item, you can find out what context variables you have available, in this example, we fed the parameter $issue from the web item to the servlet, but you can find out which parameters that you have available at your web item by printing them out, and you can even add your own to the map if you need to.
public class RequestContextProvider implements ContextProvider {
@Override
public void init(Map<String, String> map) throws PluginParseException {
}
@Override
public Map<String, Object> getContextMap(Map<String, Object> map) {
if (map != null) {
for (Map.Entry<String,Object> entry : map.entrySet()) {
System.out.println(entry.getKey() + " : " + entry.getValue().toString());
}
} else {
//no context map found
}
return map; //dont add anything to the map, but you can add parameters if you want
}
}
