Injecting SoyTemplateRenderer in custom Atlassian JIRA plugin - spring

Question

I'm currently trying to develop a custom Jira plugin, which also uses a servlet to render a Soy template.
This is the code of my servlet:
/*
* To change this license header, choose License Headers in Project Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
package at.fraiss.plugins.custommenuitem.servlets;
import javax.servlet.*;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import com.atlassian.soy.renderer.SoyTemplateRenderer;
import java.util.HashMap;
import java.util.Map;
/**
*
* #author Mario
*/
public class SoyTemplateServlet extends HttpServlet {
private SoyTemplateRenderer soyTemplateRenderer;
public SoyTemplateServlet(SoyTemplateRenderer soyTemplateRenderer)
{
this.soyTemplateRenderer = soyTemplateRenderer;
}
#Override
public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException
{
response.setContentType("text/html");
response.getWriter().write(getHtml());
}
public String getHtml()
{
Map<String, Object> data = new HashMap<String,Object>();
data.put("isLocal", true);
data.put("url", "http://www.example.com");
data.put("title", "example");
return this.soyTemplateRenderer.render("jira.webresources:soy-templates", "JIRA.Templates.Links.helpLink", data);
}
}
This is how I defined the soy template files inside the atlassian-plugin.xml descriptor:
<web-resource key="soy-templates">
<dependency>com.atlassian.soy.soy-template-plugin:soy-deps</dependency>
<!-- Available to the server-side only -->
<resource type="soy" name="links" location="links.soy"/>
 
<!-- Make available to the client-side in JS as well... -->
<transformation extension="soy">
<transformer key="soyTransformer"/>
</transformation>
<resource type="download" name="Links.soy.js" location="links.soy"/>
</web-resource>
I have added the following section to my pom.xml:
<dependency>
<groupId>com.atlassian.soy</groupId>
<artifactId>soy-template-renderer-api</artifactId>
<version>4.0.4</version>
<scope>provided</scope>
</dependency>
and always get this error when try to acces the servlet

Answer 1

I also had this problem (and lost hours on it).
The Spring scanner apparently only processes classes marked with #Named.
This worked for me:
#Named("MyServlet")
public class MyServlet extends HttpServlet{
#ComponentImport
private final SoyTemplateRenderer soyTemplateRenderer;
#Inject
public MyServlet(#ComponentImport final SoyTemplateRenderer soyTemplateRenderer) {
this.soyTemplateRenderer = soyTemplateRenderer;
}
}

Apparently this has nothing to do with jiira, but in your frustration you seem to be blaming it and its documentation. It's actually a problem with your use of spring, and your apparent inability to read stack traces.
The first entry in the stack trace mentions, in may different ways, No qualif
ying bean of type [com.atlassian.soy.renderer.SoyTemplateRenderer] found. So, you seem to have not provided a bean definition for the SoyTemplateRenderer for spring to find. Rectify this and this particular problem will disappear.
