无法在CQ中部署SlingServlet
我正在尝试在CQ中创建一个servlet来访问一些后端服务。 然后从我的页面将进行AJAX调用以从servlet获取响应。
@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，
$(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。 请参考吊索文档 ，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 – 用于此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); } }
