1.2 核心技术栈选型

组件	功能	物流场景特殊配置
Tomcat 10.1	Web服务容器	自定义线程池优化
MySQL 8.0	订单数据存储	分库分表按区域划分
Redis 7.0	实时位置缓存	启用GeoHash索引
RabbitMQ 3.12	异步任务处理	优先级队列按时效分级

二、Tomcat集群部署方案

2.1 服务器规划

采用3节点集群部署，每节点配置：

CPU：8核Intel Xeon Gold 6248
内存：32GB DDR4 ECC
存储：1TB NVMe SSD
网络：双10Gbps网卡绑定

2.2 server.xml核心配置

<Service name="Catalina">
  <!-- 自定义线程池适应物流高峰期 -->
  <Executor name="logisticsThreadPool" 
            namePrefix="catalina-exec-"
            maxThreads="500" 
            minSpareThreads="50"
            maxIdleTime="60000"
            prestartminSpareThreads="true"/>

  <!-- HTTP连接器优化 -->
  <Connector executor="logisticsThreadPool"
             port="8080"

             maxConnections="10000"
             redirectPort="8443"
             compression="on"
             compressionMinSize="2048"
             noCompressionUserAgents="gozilla, traviata"
             compressableMimeType="text/html,text/xml,application/json"/>

  <!-- AJP连接器用于负载均衡 -->
  <Connector protocol="AJP/1.3"
             address="0.0.0.0"
             port="8009"
             secretRequired="true"
             secret="logistics_ajp_secret_2025"/>

  <!-- 集群配置 -->
  <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"
           channelSendOptions="8">
    <Manager className="org.apache.catalina.ha.session.DeltaManager"
             expireSessionsOnShutdown="false"
             notifyListenersOnReplication="true"/>
    <Channel className="org.apache.catalina.tribes.group.GroupChannel">
      <Membership className="org.apache.catalina.tribes.membership.McastService"
                  address="228.0.0.4"
                  port="45564"
                  frequency="500"
                  dropTime="3000"/>
      <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"

                autoBind="100"
                selectorTimeout="5000"
                maxThreads="6"/>
    </Channel>
  </Cluster>
</Service>

2.3 线程池性能调优

<Executor name="logisticsThreadPool"
          namePrefix="catalina-exec-"
          maxThreads="500"
          minSpareThreads="50"
          maxIdleTime="60000"
          prestartminSpareThreads="true"
          threadPriority="5"
          className="org.apache.catalina.core.StandardThreadExecutor"/>

三、数据持久化与缓存策略

3.1 上下文配置（context.xml）

<Context>
  <!-- 会话持久化配置 -->
  <Manager className="org.apache.catalina.session.PersistentManager"
           maxIdleSwap="30">
    <Store className="org.apache.catalina.session.JDBCStore"
           driverName="com.mysql.cj.jdbc.Driver"
           connectionURL="jdbc:mysql://db-cluster/logistics_sessions"
           connectionName="tomcat"
           connectionPassword="session_db_password"
           sessionTable="tomcat_sessions"
           sessionIdCol="session_id"
           sessionDataCol="session_data"
           sessionValidCol="valid_session"
           sessionMaxInactiveCol="max_inactive"
           sessionLastAccessedCol="last_access"/>
  </Manager>

  <!-- JNDI数据源配置 -->
  <Resource name="jdbc/LogisticsDB"
            auth="Container"
            type="javax.sql.DataSource"
            driverClassName="com.mysql.cj.jdbc.Driver"
            url="jdbc:mysql://db-cluster/logistics?useSSL=false"
            username="dbuser"
            password="dbpass"
            maxTotal="100"
            maxIdle="20"
            minIdle="5"
            initialSize="10"
            validationQuery="SELECT 1"
            testOnBorrow="true"
            timeBetweenEvictionRunsMillis="30000"/>
</Context>

3.2 Redis缓存集成

创建redis-context.xml放置于conf/Catalina/localhost/目录：

<Context>
  <Resource name="redis/ConnectionFactory"
            auth="Container"
            type="redis.clients.jedis.JedisPool"
            factory="org.apache.catalina.redisson.JedisPoolFactory"
            host="redis-cluster"
            port="6379"
            password="redis_password"
            database="1"
            maxTotal="200"
            maxIdle="50"
            minIdle="10"
            testOnBorrow="true"/>
</Context>

四、安全加固措施

4.1 访问控制配置

<Valve className="org.apache.catalina.valves.RemoteAddrValve"
       allow="192.168.100.*|10.0.20.*"/>
<Valve className="org.apache.catalina.valves.RemoteHostValve"
       deny=".*\.untrusted\.com"/>

4.2 SSL/TLS配置

<Connector port="8443"
           protocol="org.apache.coyote.http11.Http11Nio2Protocol"
           maxThreads="200"
           SSLEnabled="true">
  <UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol"/>
  <SSLHostConfig>
    <Certificate certificateKeystoreFile="conf/keystore.p12"
                 certificateKeystorePassword="keystore_password"
                 certificateKeystoreType="PKCS12"
                 type="RSA"
                 keyAlias="logistics_tomcat"/>
    <OpenSSLConf>
      <OpenSSLConfCmd name="Protocol" value="TLSv1.3 TLSv1.2"/>
      <OpenSSLConfCmd name="CipherSuite" value="TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256"/>
    </OpenSSLConf>
  </SSLHostConfig>
</Connector>

五、监控与运维体系

5.1 访问日志配置

<Valve className="org.apache.catalina.valves.AccessLogValve"
       directory="logs"
       prefix="logistics_access_log"
       suffix=".txt"
       pattern="%h %l %u %t &quot;%r&quot; %s %b &quot;%{Referer}i&quot; &quot;%{User-Agent}i&quot; %D"
       rotatable="true"
       maxDays="30"
       fileDateFormat="yyyy-MM-dd"/>

5.2 健康检查接口开发

@WebServlet("/health")
public class HealthCheckServlet extends HttpServlet {
    protected void doGet(HttpServletRequest request, HttpServletResponse response) 
            throws ServletException, IOException {
        // 检查数据库连接
        boolean dbOk = checkDatabaseConnection();
        // 检查Redis连接
        boolean redisOk = checkRedisConnection();
        // 检查消息队列
        boolean mqOk = checkMQConnection();
        
        response.setContentType("application/json");
        if (dbOk && redisOk && mqOk) {
            response.setStatus(HttpServletResponse.SC_OK);
            response.getWriter().write("{\"status\":\"UP\"}");
        } else {
            response.setStatus(HttpServletResponse.SC_SERVICE_UNAVAILABLE);
            response.getWriter().write("{\"status\":\"DOWN\"}");
        }
    }
    
    // 健康检查实现方法省略...
}

六、高可用架构设计

6.1 负载均衡配置（Nginx示例）

upstream tomcat_cluster {
    server tomcat-node1:8080 weight=3;
    server tomcat-node2:8080 weight=3;
    server tomcat-node3:8080 weight=4;
    
    ip_hash;
    keepalive 32;
}

server {
    listen 80;
    server_name tracking.logistics.com;
    
    location / {
        proxy_pass http://tomcat_cluster;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_connect_timeout 3s;
        proxy_send_timeout 10s;
        proxy_read_timeout 30s;
    }
}

6.2 故障自动转移流程

七、部署与运维自动化

7.1 部署脚本（deploy.sh）

#!/bin/bash
# 物流系统Tomcat部署脚本

# 变量定义
APP_NAME="logistics-tracking.war"
TOMCAT_HOME="/opt/tomcat"
BACKUP_DIR="/backup/tomcat"
DATE=$(date +%Y%m%d_%H%M%S)

# 备份现有应用
echo "Creating backup of current application..."
mkdir -p $BACKUP_DIR
cp $TOMCAT_HOME/webapps/$APP_NAME $BACKUP_DIR/$APP_NAME.$DATE

# 停止Tomcat
echo "Stopping Tomcat..."
$TOMCAT_HOME/bin/shutdown.sh
sleep 10

# 部署新应用
echo "Deploying new application..."
cp /tmp/$APP_NAME $TOMCAT_HOME/webapps/

# 启动Tomcat
echo "Starting Tomcat..."
$TOMCAT_HOME/bin/startup.sh

# 检查部署状态
echo "Checking deployment status..."
sleep 30
if grep -q "Deployment of web application archive" $TOMCAT_HOME/logs/catalina.out; then
    echo "Deployment successful!"
else
    echo "Deployment failed! Check logs for details."
    # 自动回滚机制
    echo "Rolling back to previous version..."
    cp $BACKUP_DIR/$APP_NAME.$DATE $TOMCAT_HOME/webapps/$APP_NAME
    $TOMCAT_HOME/bin/startup.sh
fi

7.2 监控告警配置（prometheus.yml）

scrape_configs:
  - job_name: 'tomcat'
    metrics_path: '/metrics'
    scrape_interval: 5s
    static_configs:
      - targets: ['tomcat-node1:9090', 'tomcat-node2:9090', 'tomcat-node3:9090']
    
  - job_name: 'application'
    metrics_path: '/actuator/prometheus'
    scrape_interval: 10s
    static_configs:
      - targets: ['tomcat-node1:8080', 'tomcat-node2:8080', 'tomcat-node3:8080']
