使用ajp进行Spring Boot应用程序的Apache背后的Tomcat

Question

我一直在尝试使用嵌入式Tomcat的Spring Boot应用程序配置Apache Web服务器.在Spring Boot之前我曾经创建过一个ajp.conf文件,如:

<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>

并包含在httpd.conf文件中

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

在Tomcat的server.xml文件中,我曾经将它配置为侦听端口8009

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

此设置有效.但是,现在使用Spring Boot我正在尝试使用嵌入式tomcat实现类似的功能.我在这里阅读了Spring Boot Documentation,并在我的application.yml文件中添加了以下属性:

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

我的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/
   ProxyPassReverse /app ajp://localhost:8009/

 </VirtualHost>

我有我的spring boot tomcat配置类

@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;
}

在我的apache错误日志中,我看到:

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) (*)

不知道这里发生了什么.我在网上搜索了很多,但找不到关于如何使用spring boot应用程序在apache后面提供tomcat的好文档.最后,我想对多个tomcat实例进行负载均衡.

从以上评论中推断:

@Configuration
public class TomcatAjpConfig {

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

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

private static Connector createConnector() {
    Connector connector = new Connector("AJP/1.3");
    connector.setPort(8009);
    return connector;
}

}
