我在CQ5应用程序中创建了一个servlet:
import java.io.IOException;
import javax.servlet.ServletException;
import org.apache.felix.scr.annotations.sling.SlingServlet;
import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.SlingHttpServletResponse;
import org.apache.sling.api.servlets.SlingAllMethodsServlet;
@SlingServlet(
label = "Example Servlet",
paths = {"/bin/project/signin"},
methods = {"GET"},
extensions = {"html"},
metatype = false
)
public class SignInServlet extends SlingAllMethodsServlet {
private static final long serialVersionUID = 796802690004962223L;
@Override
protected void doGet(SlingHttpServletRequest request,
SlingHttpServletResponse response) throws ServletException,
IOException {
doPost(request, response);
}
@Override
protected void doPost(SlingHttpServletRequest request,
SlingHttpServletResponse response) throws ServletException,
IOException {
response.setContentType("text/plain");
response.getOutputStream().print("Sigin Servlet");
}
}
我尝试通过rest-client调用它,但它返回:
No resource found for url: http://localhost:4502/bin/project/signin
我还在Felix一侧打开Sling Resource Resolver来测试它是否可用。但我收到了:
NonExistingResource, path=/bin/project/signin
/bin/
已在Apache Sling Servlet /脚本解析器和Fellix的错误处理程序中配置

在@SlingServlet
注释中,您声明此servlet仅支持.html
扩展名的请求,因此您应该点击以下网址:
http://localhost:4502/bin/project/signin.html
如果您不想使用扩展名,请从servlet注释中删除相应的参数。

两种帮助调试此类情况的方法 -
E.g。在你的情况下,我认为404正在给出类似的东西:
LOG Resource Path Info: SlingRequestPathInfo: \
path='/bin/project/signin', \
selectorString='null', \
extension='null', \
suffix='null'
将此与注释中的设置进行比较,这里有一个 extension ='null',它与您的servlet不匹配 - 仅绑定'html'扩展,正如Tomek正确地说的那样。
