我正在尝试将SSL与Tomcat和APR连接器一起使用。我可以对服务器进行更改,但不能对现有的Java客户端进行更改。
出于某种原因,只要Java客户端使用SSL连接到Tomcat服务器,它就无法连接 - 服务器会重置连接。但是,完全相同的Java代码可以连接到Apache使用SSL托管的不同端口上的同一服务器。此外,非Java代码(如curl)可以连接到Tomcat SSL连接。
我已经通过强制Java客户端使用TLSv1协议(-Dhttps.protocols = TLSv1)来实现这一点。但是,这不是一个实用的解决方案,因为我目前无法为Java客户端发布更新。
由于这适用于服务器上的Apache,在我看来,我应该能够在服务器上进行某种配置更改,以便与Tomcat一起使用,而无需更改Java客户端。
总结: Java连接到Tomcat SSL = FAIL
卷曲连接到Tomcat SSL =好
Java连接到Apache SSL =好
卷曲连接到Apache SSL =好
以下是一些说明问题的示例Java代码。我在Mac OS X上运行Java 6。
public class SSLConnectTest {
public static void main(String[] args) throws Exception {
System.setProperty( "javax.net.debug", "all" );
testConnection( "https://secure2.360works.com" ); //Apache running SSL. This works.
testConnection( "https://secure2.360works.com:8443/" ); //Tomcat running SSL and APR. This fails.
}
private static void testConnection( String urlString ) throws IOException {
new URL( urlString ).openStream().close();
}
}
以下是SSL握手中发生的情况:

这是server.xml中的连接器配置。我希望这里的一些改变能解决问题:
<Connector port="8443" SSLEnabled="true"
maxThreads="150" scheme="https" secure="true"
sslProtocol="SSLv2+TLSv1+SSLv3"
SSLHonorCipherOrder="true"
protocol="org.apache.coyote.http11.Http11AprProtocol"
clientAuth="false" SSLCertificateFile="/etc/apache2/ssl.crt/secure2.360works.com.crt"
SSLCertificateKeyFile="/etc/apache2/ssl.crt/secure2.360works.com.key"
SSLCertificateChainFile="/etc/apache2/ssl.crt/secure2.360works.com.chcrt" />
答案 0 :(得分:3)
main, WRITE: TLSv1 Handshake, length = 81 main, WRITE: SSLv2 client hello message, length = 110
我认为这是来自Java 6环境(除非客户端明确启用了SSLv2Hello
协议)。您是否尝试在Java 7 JRE(doesn't enable SSLv2Hello
by default)上运行时查看客户端是否能够连接。
我猜这个问题的发生是因为APR连接器可能不喜欢接收SSLv2客户端Hello(来自Java,实际上不是SSLv2客户端Hello,而是包含在v2中的v3,请参阅{{3} })。
可以解决这个问题的一些建议:
