如何修改net.schmizz.sshj日誌級別？

Question

我可以更改記錄的水平，爲默認配置或禁用它sshj庫到目前爲止我的代碼[

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

，當我嘗試上面的代碼我有這些問題：

[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 
[main] WARN net.schmizz.sshj.DefaultConfig - Illegal key size 
[main] WARN net.schmizz.sshj.DefaultConfig - Illegal key size 
[main] WARN net.schmizz.sshj.DefaultConfig - No such algorithm: IDEA/CBC/NoPadding 
[main] WARN net.schmizz.sshj.DefaultConfig - No such algorithm: IDEA/CTR/NoPadding

[main] WARN net.schmizz.sshj.DefaultConfig - Illegal key size or default parameters 
[main] WARN net.schmizz.sshj.DefaultConfig - Disabling high-strength ciphers: cipher strengths apparently limited by JCE policy

SSHJ使用slf4j日誌記錄API。這意味着你可以使用任何實現slf4j的日誌實現來配置它。通常這是logback記錄器。

您可以通過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> 

順便說一句，你看到這些消息的原因是，你沒有無限強度加密擴展運行。
