本文整理了Java中org.sonar.api.utils.log.Logger类的一些代码示例，展示了Logger类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Logger类的具体详情如下：
包路径：org.sonar.api.utils.log.Logger
类名称：Logger

Logger介绍

[英]SonarQube plugins are not coupled with external logging libraries like SLF4J or Logback.

Example:

public class MyClass { 
private static final Logger LOGGER = Loggers.get("logger_name"); 
public void doSomething() { 
LOGGER.info("something valuable for production environment"); 
LOGGER.warn("message with arguments {} and {}", "foo", 42); 
} 
}

Message arguments are defined with {}, but not with java.util.Formatter syntax.

INFO, WARN and ERROR levels are always enabled. They can't be disabled by users. DEBUG and TRACE levels are enabled on demand with the property sonar.log.level.

See org.sonar.api.utils.log.LogTester for testing facilities.
[中]SonarQube插件不与SLF4J或Logback等外部日志库耦合。
例子：

public class MyClass { 
private static final Logger LOGGER = Loggers.get("logger_name"); 
public void doSomething() { 
LOGGER.info("something valuable for production environment"); 
LOGGER.warn("message with arguments {} and {}", "foo", 42); 
} 
}

消息参数是用{}定义的，但不是用java定义的。util。格式化程序语法。
信息、警告和错误级别始终处于启用状态。用户不能禁用它们。调试和跟踪级别是按需使用属性sonar.log.level启用的。
见组织。声纳。应用程序编程接口。乌提尔斯。日志用于测试设施的LogTester。
