是否抑制所有 Logback 输出到控制台？

如何配置Logback以抑制其所有输出到控制台（标准输出）？特别是，我希望抑制（或重定向）Logback的自身日志消息，例如以下内容：

16:50:25,814 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Could NOT find resource [logback-test.xml]
16:50:25,814 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Found resource [logback.xml] at [file:/opt/dap/domains/ap0491/uat1/domain/instance-config/logback.xml]
16:50:25,816 |-WARN in ch.qos.logback.classic.LoggerContext[default] - Resource [logback.xml] occurs multiple times on the classpath.
16:50:25,816 |-WARN in ch.qos.logback.classic.LoggerContext[default] - Resource [logback.xml] occurs at [file:/opt/dap/domains/ap0491/uat1/domain/instance-config/logback.xml]
16:50:25,816 |-WARN in ch.qos.logback.classic.LoggerContext[default] - Resource [logback.xml] occurs at [file:/opt/dap/domains/ap0491/uat1/domain/instance-config/logback.xml]
16:50:25,923 |-INFO in ch.qos.logback.classic.joran.action.ConfigurationAction - debug attribute not set
16:50:25,924 |-INFO in ch.qos.logback.classic.turbo.ReconfigureOnChangeFilter@1a15291 - Will scan for changes in file [/opt/dap/domains/ap0491/uat1/domain/instance-config/logback.xml] every 60 seconds. 

由于我们的生产环境禁止应用程序向标准输出打印任何消息，因此我需要禁用所有输出到标准输出的日志记录。

请注意，我正在使用Logback 0.9.21，SLF4J 1.6.0，我们的应用程序在WebLogic 10.3.2中运行。
