35.7.3. 使用 Request-Reply 通信基于 SSL/TCP 的 Netty 消费者端点

使用 JSSE 配置实用程序

Netty 组件通过 Camel JSSE 配置实用程序 支持 SSL/TLS 配置。这个实用程序可大大减少您需要编写的组件特定代码的数量，并在端点和组件级别进行配置。以下示例演示了如何在 Netty 组件中使用 实用程序。

组件的编程配置

KeyStoreParameters ksp = new KeyStoreParameters();
ksp.setResource("/users/home/server/keystore.jks");
ksp.setPassword("keystorePassword");

KeyManagersParameters kmp = new KeyManagersParameters();
kmp.setKeyStore(ksp);
kmp.setKeyPassword("keyPassword");

SSLContextParameters scp = new SSLContextParameters();
scp.setKeyManagers(kmp);

NettyComponent nettyComponent = getContext().getComponent("netty", NettyComponent.class);
nettyComponent.setSslContextParameters(scp);

基于 Spring DSL 的端点配置

...
  <camel:sslContextParameters
      id="sslContextParameters">
    <camel:keyManagers
        keyPassword="keyPassword">
      <camel:keyStore
          resource="/users/home/server/keystore.jks"
          password="keystorePassword"/>
    </camel:keyManagers>
  </camel:sslContextParameters>...
...
  <to uri="netty:tcp://0.0.0.0:5150?sync=true&ssl=true&sslContextParameters=#sslContextParameters"/>
...

在 Jetty 组件上使用基本 SSL/TLS 配置

Registry registry = context.getRegistry();
registry.bind("password", "changeit");
registry.bind("ksf", new File("src/test/resources/keystore.jks"));
registry.bind("tsf", new File("src/test/resources/keystore.jks"));

context.addRoutes(new RouteBuilder() {
  public void configure() {
      String netty_ssl_endpoint =
         "netty:tcp://0.0.0.0:5150?sync=true&ssl=true&passphrase=#password"
         + "&keyStoreFile=#ksf&trustStoreFile=#tsf";
      String return_string =
         "When You Go Home, Tell Them Of Us And Say,"
         + "For Your Tomorrow, We Gave Our Today.";

      from(netty_ssl_endpoint)
       .process(new Processor() {
          public void process(Exchange exchange) throws Exception {
            exchange.getOut().setBody(return_string);
          }
       }
  }
});

获取 SSLSession 和客户端证书访问权限

如果要访问 javax.net.ssl.SSLSession，则可获得有关客户端证书的详细信息。当 ssl=true 之后，Netty 组件会将 SSLSession 保存为 Camel 消息上的标头，如下所示：
