spring - 在自定义 Atlassian JIRA 插件中注入(inject) SoyTemplateRenderer

Question

我目前正在尝试开发自定义 Jira 插件，它也使用 servlet 来呈现 Soy 模板。

这是我的 servlet 的代码:

    /*
 * 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);
    }
}

这就是我在 atlassian-plugin.xml 描述符中定义 soy 模板文件的方式:

<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>

我已将以下部分添加到我的 pom.xml 中:

<dependency>
        <groupId>com.atlassian.soy</groupId>
        <artifactId>soy-template-renderer-api</artifactId>
        <version>4.0.4</version>
        <scope>provided</scope>
    </dependency>

并且在尝试访问 servlet 时总是出现此错误

我也遇到了这个问题(并且为此浪费了时间)。

Spring 扫描器显然只处理标有@Named 的类。

这对我有用:

@Named("MyServlet")
public class MyServlet extends HttpServlet{
    @ComponentImport
    private final SoyTemplateRenderer soyTemplateRenderer;

    @Inject
    public MyServlet(@ComponentImport final SoyTemplateRenderer soyTemplateRenderer) {
        this.soyTemplateRenderer = soyTemplateRenderer;
    }
}
