我正在尝试对我的Jetty服务器上的页面之一进行身份验证。我正在以编程方式完成所有操作,因此不涉及xml。

我发现我可以使用ConstraintSecurityHandler保护特定的上下文。尽管这对于我正在运行的Servlet来说很好用,但我尝试将其扩展为也可以用于ResourceHandler,但遇到了问题。我正在尝试的代码位于下面。

如果我首先放置ResourceHandler块,那么身份验证将无法弹出。
如果将ResourceHandler块放置在SecurityHandler块之后,则会弹出身份验证,但是在身份验证之后,ResourceHandler页面(/ resources)不会出现,并且Jetty给我一个404。

有什么方法可以通过密码保护ResourceHandler托管的页面吗?

final static String REALM = "REALM";

public static void main(String[] args){

    ResourceHandler resourceHandler = new ResourceHandler(); //set up resourceHandler to host directory of files at /resources
    resourceHandler.setDirectoriesListed(true);
    resourceHandler.setResourceBase("." + File.separator + "files");
    ContextHandler resourceContextHandler = new ContextHandler();
    resourceContextHandler.setContextPath("/resources");
    resourceContextHandler.setHandler(resourceHandler);
    handlers.addHandler(resourceContextHandler);
.
.
.
    ConstraintSecurityHandler csh = getConstraintSecurityHandler();
    ServletContextHandler servletContextHandler = new ServletContextHandler(ServletContextHandler.SESSIONS);
    servletContextHandler.setSecurityHandler(csh);
    handlers.addHandler(servletContextHandler);
.
.
.

    server.setHandler(handlers);
    server.start();
    server.join();
}

private ConstraintSecurityHandler getConstraintSecurityHandler(){
    Constraint constraint = new Constraint(Constraint.__BASIC_AUTH, "user");
    constraint.setRoles(new String[]{"user","admin"});
    constraint.setAuthenticate(true);

    ConstraintMapping statsConstraintMapping = new ConstraintMapping();
    statsConstraintMapping.setConstraint(constraint);
    statsConstraintMapping.setPathSpec("/resources"); //directory I want to protect

    ConstraintSecurityHandler csh = new ConstraintSecurityHandler();
    csh.setAuthenticator(new BasicAuthenticator());
    csh.setRealmName(REALM);
    csh.setConstraintMappings(new ConstraintMapping[] {statsConstraintMapping});

    csh.setLoginService(getHashLoginService());

    return csh;
}

private HashLoginService getHashLoginService() {
    HashLoginService loginServ = new HashLoginService();
    loginServ.setName(REALM);
    loginServ.setConfig("realm.properties"); //location of authentication file
    loginServ.setRefreshInterval(1);
    return loginServ;
}

最佳答案

安全处理程序位于资源处理程序的前面,因此在处理链中首先要查询安全处理程序。
