Logback 接收器 - 无法处理类型类 ReceiverModel 的模型

Question

我无法让 Logback ServerSocketReceiver 工作。我运行 Logback 自己的完整示例时遇到完全相同的问题https://logback.qos.ch/manual/receivers.html.

简化

logback.xml

：

<configuration debug="true">
    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>[%date]-%msg%n</pattern>
        </encoder>
    </appender>
    <root level="DEBUG">
        <appender-ref ref="CONSOLE" />
    </root>
    <receiver class="ch.qos.logback.classic.net.server.ServerSocketReceiver">
        <port>3331</port>
    </receiver>
</configuration>

套接字服务器甚至从未启动：

ERROR in ch.qos.logback.core.model.processor.DefaultProcessor@76b10754 - Can't handle model of type class ch.qos.logback.classic.model.ReceiverModel  with tag: receiver at line 11

使用此设置完成输出：

任何帮助将非常感激。

我尝试了 Java 8、11 和 17。我尝试了 Logback 的多个版本，但更喜欢 1.3.x，因为我在生产中一直使用 Java 8。（最终我会切换到 SSLSocketReceiver/appender）

（Logback 套接字附加器/接收器的附加器端似乎工作得很好。我使用 nc 将测试 SocketAppender 连接到小型套接字服务器（https://linux.die.net/man/1/nc））

当 Logback 初始化时我得到

ERROR in ch.qos.logback.core.model.processor.DefaultProcessor@76b10754 - Can't handle model of type class ch.qos.logback.classic.model.ReceiverModel  with tag: receiver at line 11

我希望 Logback 启动一个套接字服务器来开始侦听端口 3331。

Answer 1

如果您使用的是 logback 1.3，那么您需要注意您链接的页面上代码示例的 Canonical (1.3) 选项卡：

---

解决方案

<receiver class="ServerSocketReceiver">
    <port>3331</port>
</receiver>

接收者 xml 必须如上所示。

注意：班级是

ServerSocketReceiver

不是

ch.qos.logback.classic.net.server.ServerSocketReceiver

。
