无法在CQ中部署SlingServlet

标签： java cq5 servlet-3.0 sling

我试图在CQ中创建一个servlet来访问一些后端服务。然后从我的页面进行AJAX调用以获取servlet的响应。

@Component(immediate = true, metatype = false, label = "feedServlet")
@Service(Servlet.class)
@Properties(value = {
    @org.apache.felix.scr.annotations.Property(name = "sling.servlet.methods", value = "POST"),
    @org.apache.felix.scr.annotations.Property(name = "sling.servlet.resourceTypes", value ="/bin/feedServlet/"),
    @org.apache.felix.scr.annotations.Property(name = "sling.servlet.selectors", value ="POST"),
    @org.apache.felix.scr.annotations.Property(name = "sling.servlet.extensions", value ="html")
})
/**
 * This servlet returns search results in json format.
 */
public class FeedServlet extends SlingAllMethodsServlet {

    private static final long serialVersionUID = -2139716879248038562L;

    /*
     * Inject the service in to the servlet.
     */
    // @Reference(cardinality = ReferenceCardinality.MANDATORY_UNARY, policy = ReferencePolicy.STATIC)
    // private SearchService searchService;

    // @Reference(cardinality = ReferenceCardinality.MANDATORY_UNARY, policy = ReferencePolicy.STATIC)
    // private FeedGeneratorService feedService;

    /*
     * @Reference private SlingRepository repository;
     */

    /**
     * Bind repository.
     * 
     * @param repository the repository
     */
    /*
     * public void bindRepository(SlingRepository repository) { this.repository = repository; }
     */

    /*
     * (non-Javadoc)
     * 
     * @see org.apache.sling.api.servlets.SlingAllMethodsServlet#doPost(org.apache.sling.api.SlingHttpServletRequest,
     * org.apache.sling.api.SlingHttpServletResponse)
     */
    @Override
    protected void doPost(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServerException,
            IOException {

        String feed = "test test test";

        response.getWriter().write(feed);
    }

从我的页面开始，

$(document).ready(function(){
  $("#button1").click(function(){
      alert(0);
      var formData = 'tcc=123';
      $.ajax({
            url : '/bin/feedServlet/',
            type: 'POST',
           data : formData,
         success: function(data, textStatus, jqXHR)
         {
             alert("1 : "+data);
            // alert(eval(jqXHR));
            //data - response from server
        },
        error: function (jqXHR, textStatus, errorThrown)
        {
            alert(errorThrown);
        }
      });
  });

});

但是，在提出请求时我收到了错误：

你的财产有问题。请参考sling docs以了解您设置的每个属性的作用。

应该使用属性sling.servlet.paths而不是sling.servlet.resourceTypes来提供servlet作为资源可访问的路径。

因此，根据您的要求，以下注释就足够了。

sling.servlet.methods - 对于servlet支持的请求方法。

sling.servlet.paths - 对于此servlet处理的请求路径。

@Component(immediate = true, metatype = false, label = "feedServlet")
@Service(Servlet.class)
@Properties(value = {
    @org.apache.felix.scr.annotations.Property(name = "sling.servlet.methods", value = "POST"),
    @org.apache.felix.scr.annotations.Property(name = "sling.servlet.paths", value ="/bin/feedServlet"))
})
public class FeedServlet extends SlingAllMethodsServlet {

    private static final long serialVersionUID = -2139716879248038562L;

    @Override
    protected void doPost(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServerException,
            IOException {

        String feed = "test test test";

        response.getWriter().write(feed);
    }
}
