如何修改net.schmizz.sshj日志级别？

Question

我可以更改记录的水平，为默认配置或禁用它sshj库到目前为止我的代码[

Config config = new DefaultConfig(); 
config.setKeepAliveProvider(KeepAliveProvider.KEEP_ALIVE); 
SSHClient sshClient = new SSHClient(config); 

，当我尝试上面的代码我有这些问题：

[main] WARN net.schmizz.sshj.DefaultConfig - Illegal key size 
[main] WARN net.schmizz.sshj.DefaultConfig - Illegal key size 
[main] WARN net.schmizz.sshj.DefaultConfig - Illegal key size

SSHJ使用slf4j日志记录API。这意味着你可以使用任何实现slf4j的日志实现来配置它。通常这是logback记录器。

您可以通过添加含有例如以下配置的logback.xml文件配置：

<configuration> 

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> 
    <encoder> 
     <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%.-20thread] %-5level %logger{36} - %msg%n</pattern> 
    </encoder> 
    </appender> 

    <root level="info"> 
    <appender-ref ref="STDOUT"/> 
    </root> 

    <logger name="net.schmizz.sshj" level="error"/> 

</configuration> 

顺便说一句，你看到这些消息的原因是，你没有无限强度加密扩展运行。
