plugins - Jira SAL using PluginSettings -

i looked way store project-specific configurations plugin. in first step want store simple string "hello".

so, found sal , pluginsettings. https://developer.atlassian.com/docs/atlassian-platform-common-components/shared-access-layer/sal-services

this seems pretty easy use don´t have idea how implement code. used webwork taking place in project administration section:

@override public string dodefault() throws exception {     project project = getprojectmanager().getprojectobjbykey(_projectkey);     httpservletrequest request = executinghttprequest.get();     request.setattribute((new stringbuilder()).append("com.atlassian.jira.projectconfig.util.servletrequestprojectconfigrequestcache").append(":project").tostring(), project);     return input; }  @override protected string doexecute() throws exception {     project project = getprojectmanager().getprojectobjbykey(_projectkey);     httpservletrequest request = executinghttprequest.get();     request.setattribute((new stringbuilder()).append("com.atlassian.jira.projectconfig.util.servletrequestprojectconfigrequestcache").append(":project").tostring(), project);     string param = request.getparameter("param");     return success; }  public void setprojectkey(string projectkey) {     _projectkey = projectkey;     }  public string getprojectkey() {     return _projectkey; }  public string getbaseurl() {     return componentaccessor.getapplicationproperties().getstring(apkeys.jira_baseurl); } 

as sal said implemented settings-class:

public customprojectsettings(         final pluginsettingsfactory pluginsettingsfactory,         final string projectkey) {     this.pluginsettingsfactory = pluginsettingsfactory;     this.projectkey = projectkey; }  public void setvalue(final string key, final string value) {     final pluginsettings settings = pluginsettingsfactory             .createsettingsforkey(projectkey);     settings.put(key, value); }  public object getvalue(final string key) {     final pluginsettings settings = pluginsettingsfactory             .createsettingsforkey(projectkey);     return settings.get(key); } 

and added component in xml:

<component-import key="pluginsettingsfactory" interface="com.atlassian.sal.api.pluginsettings.pluginsettingsfactory" /> 

so how connect , implement webwork

protected string doexecute() throws exception{     [...]     pluginsettings.setvalue("key", param);     [...] } 

it easier thought. had inject settings dependency webwork:

public webworkaction(customprojectsettings settings){     this.settings = settings } 

the settings-class gets autowired by

<component-import key="pluginsettingsfactory"  interface="com.atlassian.sal.api.pluginsettings.pluginsettingsfactory" /> 

and adding

<component key="settingscomponent"       class="com.xxx.customprojectsettings"> </component>
