首先，我对这篇长文表示歉意。这是我之前问题的延续（7u21更新后弹出需要验证的窗口）关于这个问题，但我缩小了搜索范围。简而言之，自 Java 7u21 以来，我的 BASIC 身份验证似乎已被破坏。
通过 JNLP 文件启动的小程序根本无法稳定运行，并会弹出身份验证窗口。
设置
首先我设置了一个MySQL数据库具有用户表和组表。
接下来我设置了一个jdbc领域在玻璃鱼中。请注意，数据库用户和数据库密码字段为空，因为我使用 JNDI（请参阅下文）：
Glassfish 领域设置：
JNDI配置（如domain.xml文件所示）：
<jdbc-connection-pool connection-validation-method="auto-commit" datasource-classname="com.mysql.jdbc.jdbc2.optional.MysqlDataSource" wrap-jdbc-objects="false" res-type="javax.sql.DataSource" name="mysql_mit_rohhPool">
<property name="URL" value="jdbc:mysql://localhost:3306/mit?zeroDateTimeBehavior=convertToNull"></property>
<property name="driverClass" value="com.mysql.jdbc.Driver"></property>
<property name="Password" value="****"></property>
<property name="portNumber" value="3306"></property>
<property name="databaseName" value="mit"></property>
<property name="User" value="****"></property>
<property name="serverName" value="localhost"></property>
</jdbc-connection-pool>
<jdbc-resource pool-name="mysql_mit_rohhPool" jndi-name="jdbc/DB_MIT"></jdbc-resource>
完成此操作后，我将默认领域更改为新创建的jdbc领域并检查了默认主体到角色映射:
TESTING
毕竟，为了进行测试，我在 Netbeans 中创建了一个简单的 WebService，它从数据库中获取一些国家/地区并配置了web.xml对于 BASIC 身份验证：
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

</login-config>
<security-role>

<role-name>dummy</role-name>
</security-role>
为了测试 Web 服务，我在 NetBeans 中右键单击它，然后单击测试 RESTful Web 服务。将打开一个新的 Internet Explorer 窗口并显示登录屏幕，我输入dummy用户和一切正常。
接下来，我创建一个简单的 JavaFX FXML 项目来获取国家/地区。我有一个班级（使用泽西岛），看起来像下面这样。这是由 Netbeans 7.3 生成的代码：
private WebResource webResource;
private Client client;
private static final String BASE_URI = "http://localhost:8080/myWS/webresources";
public CountriesClient() {
com.sun.jersey.api.client.config.ClientConfig config = new com.sun.jersey.api.client.config.DefaultClientConfig();
client = Client.create(config);
webResource = client.resource(BASE_URI).path("entities.countries");
}
public void close() {
client.destroy();
}
public void setUsernamePassword(String username, String password) {
client.addFilter(new com.sun.jersey.api.client.filter.HTTPBasicAuthFilter(username, password));
}
public <T> T findAll_XML(Class<T> responseType) throws UniformInterfaceException {
WebResource resource = webResource;
return resource.accept(javax.ws.rs.core.MediaType.APPLICATION_XML).get(responseType);
}
在我的 FXML 控制器文件中，我将此方法链接到一个按钮：
@FXML
private void handleButtonAction(ActionEvent event) {
System.out.println("You clicked me!");
CountriesClient c = new CountriesClient();
c.setUsernamePassword("dummy", "****");
String r = c.findAll_XML(String.class);
System.out.println(r);
c.close();
}
这就是我的项目的设置。现在，当我在 Netbeans 中测试它或通过 *.jar 文件启动它时，一切都按预期工作，并给出以下输出：
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><countriess><countries><country>Belgium</country><id>1</id></countries><countries><country>Ireland</country><id>2</id></countries><countries><country>United Kingdom</country><id>3</id></countries><countries><country>Poland</country><id>4</id></countries></countriess>
然而，一旦我通过 *.jnlp 文件启动小程序，我就会收到这个恼人的弹出窗口，抱怨凭据：
java控制台记录了这一点：

有几件事我实在不明白：
您遇到的症状的原因是 Oracle 有在 Web Start 中使用 JDK7 默认启用 HTTP 响应缓存:
默认启用缓存：缓存应用程序的网络内容 现在默认启用在 Web Start 模式下运行的代码。这允许 应用程序提高了小程序执行的性能和一致性 模式。为了确保使用最新的内容副本，应用程序 可以使用
URLConnection.setUseCaches(false)或请求头Cache-Controlvaluesno-cache/no-store.
所以我所做的是，在创建 Jersey 客户端后设置此标头：
Client client = Client.create();
client.addFilter( new HTTPBasicAuthFilter( userId, password ) );
client.addFilter( new ClientFilter() {
@Override
public ClientResponse handle( ClientRequest cr )
throws ClientHandlerException {
List<Object> cacheControlRequestValues = new ArrayList<Object>();
cacheControlRequestValues.add( "no-cache" );
cacheControlRequestValues.add( "no-store" );
cr.getHeaders().put( HttpHeaders.CACHE_CONTROL, cacheControlRequestValues );
return getNext().handle( cr );
}
}
现在，如果上述规范正确，并且 Web Start 的实现将遵循HTTP/1.1 参考，其中指出
no-store 指令的目的是防止无意的 释放或保留敏感信息（例如，在备份时） 磁带）。 no-store 指令适用于整个消息，并且可以 在响应或请求中发送。如果在请求中发送，则 缓存不得存储此请求或任何响应的任何部分 到它。
我们会没事的 - 网络嗅探器证明客户端正确设置了 Cache-Control 标头。泽西岛的 ContainerResponseFilter 还向我展示了request设置正确。这response另一方面没有设置 Cache-Control 标头。根据规范，应该没有关系，但实际上 Web Start 一直在缓存响应！
因此，我编写了一个 ContainerResponseFilter，它将 Cache-Control 标头从请求复制到响应：
import com.sun.jersey.spi.container.ContainerRequest;
import com.sun.jersey.spi.container.ContainerResponse;
import com.sun.jersey.spi.container.ContainerResponseFilter;
import javax.ws.rs.core.HttpHeaders;
import java.util.ArrayList;
import java.util.List;
public class CacheControlCopyFilter
implements ContainerResponseFilter
@Override
public ContainerResponse filter( ContainerRequest containerRequest, ContainerResponse containerResponse ) {
if ( containerRequest.getRequestHeader( HttpHeaders.CACHE_CONTROL ) != null ) {
List<Object> responseCacheControlValues = new ArrayList<Object>( containerRequest.getRequestHeader( HttpHeaders.CACHE_CONTROL ).size() );
for ( String value : containerRequest.getRequestHeader( HttpHeaders.CACHE_CONTROL ) ) {
responseCacheControlValues.add( value );
}
containerResponse.getHttpHeaders().put( HttpHeaders.CACHE_CONTROL, responseCacheControlValues );
}
return containerResponse;
}
}
并在web.xml
<init-param>
<param-name>com.sun.jersey.spi.container.ContainerResponseFilters</param-name>
<param-value>my.package.CacheControlCopyFilter</param-value>
</init-param>
然后你必须删除你的 Java 客户端缓存：
"javaws -viewer" -> General
-> Settings...
-> Delete Files...
-> Select all three check boxes
-> OK
瞧，不再有烦人的身份验证弹出窗口了:)
