Apache背后的Tomcat在Spring Boot应用程序中使用ajp

Question

我一直试图用一个使用嵌入式Tomcat的Spring Boot应用程序来配置Apache web server。在Spring Boot之前，我曾创建一个ajp.conf文件，如下所示：

<VirtualHost *:80>
   ServerName localhost
   <Proxy *>
      AddDefaultCharset Off
      Order deny,allow
      Allow from all
   </Proxy>

   ProxyPass /app ajp://localhost:8009/app
   ProxyPassReverse /app ajp://localhost:8009/app

 </VirtualHost>

Include /opt/lampp/apache2/conf/ajp.conf

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" connectionTimeout="5000"

server:
    port: 8080
    tomcat:
        remote_ip_header: x-forwarded-for
        protocol_header: x-forwarded-proto

<VirtualHost *:80>
   ServerName localhost
   <Proxy *>
      AddDefaultCharset Off
      Order deny,allow
      Allow from all
   </Proxy>

   ProxyPass /app ajp://localhost:8009/
   ProxyPassReverse /app ajp://localhost:8009/

 </VirtualHost>

@Configuration
public class TomcatConfiguration {

private final Logger log = LoggerFactory.getLogger(TomcatConfiguration.class);

@Bean
public EmbeddedServletContainerFactory servletContainer() {
    TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory();
    tomcat.addAdditionalTomcatConnectors(createConnector());
    tomcat.addContextValves(createRemoteIpValves());
    return tomcat;
}

private RemoteIpValve createRemoteIpValves(){
    RemoteIpValve remoteIpValve = new RemoteIpValve();
    remoteIpValve.setRemoteIpHeader("x-forwarded-for");
    remoteIpValve.setProtocolHeader("x-forwarded-protocol");
    return remoteIpValve;
}

private Connector createConnector() {
    Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
    Http11NioProtocol protocol = (Http11NioProtocol) connector.getProtocolHandler();
    connector.setScheme("ajp");
    connector.setProtocol("AJP/1.3");
    connector.setRedirectPort(8443);
    //connector.setSecure(true);
    connector.setPort(8009);
    return connector;
}

AH01080: ajp_msg_check_header() got bad signature 4854
[proxy_ajp:error] [pid 24073] AH01031: ajp_ilink_receive() received bad header
[proxy_ajp:error] ajp_read_header: ajp_ilink_receive failed
[proxy_ajp:error] (120007)APR does not understand this error code: [client xx.xx.xx.xx:60916] AH00878: read response failed from (null) (*)

不知道这是怎么回事。我在网上搜索了很多，但没有找到关于如何在apache背后使用spring boot应用程序为tomcat提供服务的好文档。最后，我还希望对多个tomcat实例进行负载平衡。

可配置通过属性或yml文件。

@Configuration
@ConfigurationProperties(prefix = "tomcat")
public class TomcatConfiguration {
   private int ajpPort = 8009;

   private boolean ajpAllowTrace = false;
   private boolean ajpSecure = false;
   private String ajpScheme = "http";
   private boolean ajpEnabled;


  @Bean
  public EmbeddedServletContainerFactory servletContainer() {

    TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory();
    if (isAjpEnabled()) {
        Connector ajpConnector = new Connector("AJP/1.3");
        ajpConnector.setProtocol("AJP/1.3");
        ajpConnector.setPort(getAjpPort());
        ajpConnector.setSecure(isAjpSecure());
        ajpConnector.setAllowTrace(isAjpAllowTrace());
        ajpConnector.setScheme(getAjpScheme());
        tomcat.addAdditionalTomcatConnectors(ajpConnector);
    }

    return tomcat;
    }
// ... Get/Set
}

application.yml

tomcat:
  ajpEnabled: true
  ajpPort: 9009
  ...
