        <property name="basename" value="messages" />
        <property name="defaultEncoding" value="UTF-8" />
    </bean>
</beans>

Tomcat配置优化

1 配置server.xml

<!-- $CATALINA_HOME/conf/server.xml 修改Connector部分 -->
<Connector port="8080" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="8443"
           maxThreads="200"
           minSpareThreads="10"
           enableLookups="false"
           acceptCount="100"
           disableUploadTimeout="true"
           URIEncoding="UTF-8"
           compression="on"
           compressionMinSize="2048"
           compressableMimeType="text/html,text/xml,text/plain,text/css,text/javascript,application/json" />

2 配置context.xml

<!-- $CATALINA_HOME/conf/context.xml 添加 -->
<Context>
    <!-- JNDI数据源配置（可选） -->
    <Resource name="jdbc/OpenClawDB"
              auth="Container"
              type="javax.sql.DataSource"
              maxTotal="100"
              maxIdle="30"
              maxWaitMillis="10000"
              username="dbuser"
              password="dbpass"
              driverClassName="com.mysql.cj.jdbc.Driver"
              url="jdbc:mysql://localhost:3306/openclawdb?useUnicode=true&amp;characterEncoding=UTF-8" />
    <!-- 会话持久化配置 -->
    <Manager className="org.apache.catalina.session.PersistentManager"
             maxIdleBackup="60"
             maxIdleSwap="0"
             processExpiresFrequency="1">
        <Store className="org.apache.catalina.session.FileStore" />
    </Manager>
</Context>

3 配置logging.properties

# $CATALINA_HOME/conf/logging.properties 添加
org.openclaw.level = INFO
org.openclaw.handlers = java.util.logging.ConsoleHandler, java.util.logging.FileHandler
org.openclaw.FileHandler.level = INFO
org.openclaw.FileHandler.pattern = ${catalina.base}/logs/openclaw.%g.log
org.openclaw.FileHandler.limit = 10485760
org.openclaw.FileHandler.count = 10
org.openclaw.FileHandler.formatter = java.util.logging.SimpleFormatter

部署和运行

1 构建和部署应用

# 1. 构建WAR包
cd /path/to/openclaw-app
mvn clean package
# 2. 部署到Tomcat（多种方式）
# 方式一：复制WAR文件到webapps目录
cp target/openclaw-app.war $CATALINA_HOME/webapps/
# 方式二：使用Tomcat Manager部署
# 首先配置manager-gui用户
# 在$CATALINA_HOME/conf/tomcat-users.xml中添加：
# <role rolename="manager-gui"/>
# <user username="admin" password="password" roles="manager-gui"/>
# 方式三：配置Context文件
# 创建 $CATALINA_HOME/conf/Catalina/localhost/openclaw-app.xml
# <Context docBase="/path/to/openclaw-app.war" />

2 启动和停止Tomcat

# 启动Tomcat
$CATALINA_HOME/bin/startup.sh
# 或
$CATALINA_HOME/bin/catalina.sh start
# 停止Tomcat
$CATALINA_HOME/bin/shutdown.sh
# 或
$CATALINA_HOME/bin/catalina.sh stop
# 查看日志
tail -f $CATALINA_HOME/logs/catalina.out

3 验证部署

访问以下URL验证部署是否成功：

  • 应用首页: http://localhost:8080/openclaw-app/
  • OpenClaw API: http://localhost:8080/openclaw-app/api/status
  • Tomcat Manager: http://localhost:8080/manager/html

高级配置

1 SSL/TLS配置

<!-- server.xml中配置SSL Connector -->
<Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol"
           maxThreads="150" SSLEnabled="true">
    <SSLHostConfig>
        <Certificate certificateKeystoreFile="conf/keystore.jks"
                     certificateKeystorePassword="changeit"
                     type="RSA" />
    </SSLHostConfig>
</Connector>

2 集群配置（可选）

<!-- server.xml中配置集群 -->
<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster">
    <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"
                  address="auto"
                  port="4000"
                  autoBind="100"
                  selectorTimeout="5000"
                  maxThreads="6"/>
        <Sender className="org.apache.catalina.tribes.transport.ReplicationTransmitter">
            <Transport className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/>
        </Sender>
        <Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>
        <Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatchInterceptor"/>
    </Channel>
</Cluster>

3 内存和性能调优

# 在$CATALINA_HOME/bin/setenv.sh中配置（如不存在则创建）
#!/bin/sh
export JAVA_OPTS="$JAVA_OPTS -server"
export JAVA_OPTS="$JAVA_OPTS -Xms512m -Xmx1024m"
export JAVA_OPTS="$JAVA_OPTS -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=256m"
export JAVA_OPTS="$JAVA_OPTS -XX:+UseG1GC"
export JAVA_OPTS="$JAVA_OPTS -XX:+DisableExplicitGC"
export JAVA_OPTS="$JAVA_OPTS -Djava.awt.headless=true"
export JAVA_OPTS="$JAVA_OPTS -Dfile.encoding=UTF-8"

故障排查

1 常见问题及解决方案

问题 可能原因 解决方案
应用无法访问 端口被占用/部署失败 检查端口占用：netstat -tlnp \| grep 8080
内存溢出 内存配置不足 调整JVM内存参数，增加Xmx值
中文乱码 字符编码不一致 确保所有组件使用UTF-8编码
类找不到 依赖缺失或冲突 检查WEB-INF/lib目录，使用mvn dependency:tree分析
启动缓慢 DNS解析问题 在JVM参数中添加：-Djava.net.preferIPv4Stack=true

2 调试日志配置

# 在应用中配置logback或log4j2
# logback.xml示例
<configuration>
    <appender name="FILE" class="ch.qos.logback.core.FileAppender">
        <file>${catalina.base}/logs/openclaw-app.log</file>
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>
    <logger name="org.openclaw" level="DEBUG" additivity="false">
        <appender-ref ref="FILE" />
    </logger>
    <root level="INFO">
        <appender-ref ref="FILE" />
    </root>
</configuration>

生产环境建议

  1. 安全配置

    • 删除默认应用（docs, examples, host-manager）
    • 修改Tomcat管理员密码
    • 启用访问日志
    • 配置防火墙规则

  2. 监控配置

    • 启用JMX监控
    • 集成APM工具（如SkyWalking, Pinpoint）
    • 配置健康检查端点

  3. 部署最佳实践

    • 使用反向代理（Nginx/Apache）
    • 配置会话持久化
    • 定期清理临时文件
    • 设置自动重启机制

通过以上步骤，您已经成功将OpenClaw应用部署到Tomcat服务器，根据实际生产需求，您可能需要进一步调整配置参数和优化性能设置，建议定期更新Tomcat和OpenClaw版本,以获得最新的功能和安全修复。
