我正在创建一个测试工具来强调加载服务器.我创建了许多不同的线程,向服务器发送单独的请求.它似乎受ChannelFactory的限制.它是进行实际服务调用的瓶颈,例如:

_proxy.MyServiceCall(...);

我尝试了几种不同的方法:

• 使用由所有线程共享的单个静态ChannelFactory
• 为每个线程创建一个新的通道工厂
• 每次调用创建一个新的通道工厂

所有这些都导致了非常相似的性能.通道工厂似乎正在使用全局静态可用连接池.我试过这个但是找不到任何东西.你对此有更多了解吗？你认为我猜有一个静态的连接池是正确的吗？如果是这样,你知道如何配置？

这是测试应用程序的当前配置:

<configuration>
  <system.serviceModel>
    <client>
      <endpoint binding="wsHttpBinding" bindingConfiguration="SynchronizationServiceBinding" contract="My.Namespace.ISynchronizationService" name="ClientBinding">
      </endpoint>
    </client>
    <bindings>
      <wsHttpBinding>
        <binding name="SynchronizationServiceBinding" maxBufferPoolSize="2147483647" maxReceivedMessageSize="10485760">
          <security mode="Transport">
            <transport clientCredentialType="None"/>
          </security>
          <reliableSession enabled="false"/>
          <readerQuotas maxArrayLength="1000000"/>
        </binding>
      </wsHttpBinding>
    </bindings>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
<startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/></startup>    </configuration>

我正在尝试在安全模式下使用更新版本的 Xalan (2.7.2) 并且遇到无法理解未知属性的问题。问题是，它阻止您使用任何发出 XHTML（在安全处理模式下）的样式表，因为它不允许“th”元素的“colspan”属性之类的东西。

相关的更改文件在这里：http : //svn.apache.org/viewvc/xalan/java/branches/xalan-j_2_7_1_maint/src/org/apache/xalan/processor/XSLTElementProcessor.java?r1=1359736&r2=1581058&pathrev=15810format =h

请参阅以下示例：

import javax.xml.XMLConstants;
import javax.xml.transform.*;
import javax.xml.transform.stream.StreamSource;
import java.io.StringReader;

public class XalanSecureAttributeRepro {
    private static final String XSL =
            "<xsl:stylesheet version=\"1.0\" xmlns:xsl=\"http://www.w3.org/1999/XSL/Transform\">\n" +
            "  <xsl:output method=\"html\"/>\n" +
            "  <xsl:template match=\"/*\">\n" +
            "    <th colspan=\"2\"/>\n" +
            "  </xsl:template>\n" +
            "</xsl:stylesheet>";

    public static void main( String[] args ) throws Exception {
        System.setProperty( "javax.xml.transform.TransformerFactory", "org.apache.xalan.processor.TransformerFactoryImpl" );

        TransformerFactory tf = TransformerFactory.newInstance();
        tf.setFeature( XMLConstants.FEATURE_SECURE_PROCESSING, true);
        tf.setErrorListener( new DefaultErrorHandler( true ) );

我注意到,最新版本的Java(1.7.0_u51)序列化和散列图的反序列化不再保留hashmap中元素的顺序.见下面的例子:

@Test
public void test() throws IOException, ClassNotFoundException {
    HashMap<String, String> map1 = new HashMap<>();
    map1.put("a1234567", "aaa");
    map1.put("b1234567", "bbb");

    System.out.println("Map1: " + map1.toString());

    byte[] serializedMap1 = objectToBytes(map1);

    System.out.println("Map1 Serialized: " + Arrays.toString(serializedMap1));

    Object map2 = bytesToObject(serializedMap1);

    System.out.println("Map2: " + map2.toString());

    byte[] serializedMap2 = objectToBytes((Serializable) map2);

    System.out.println("Map2 Serialized: " + Arrays.toString(serializedMap2));

    Object map3 = bytesToObject(serializedMap2);

    System.out.println("Map3: " + map3.toString());

    byte[] serializedMap3 = objectToBytes((Serializable) map3);

    System.out.println("Map3 Serialized: " + Arrays.toString(serializedMap3));

    Object map4 = bytesToObject(serializedMap3);

    System.out.println("Map4: " + map4.toString());

    byte[] serializedMap4 = objectToBytes((Serializable) …
