SonarQube: Invoke method(s) only conditionally
提问by Olezt
The following part of code raises a major bug at SonarQube :
"Invoke method(s) only conditionally."
How am I supposed to fix this?
以下代码部分在 SonarQube 中引发了一个主要错误：“仅有条件地调用方法。”
我该如何解决这个问题？
if(us != null){
logger.info("Log this: {}", us.toString());
}
采纳答案by Tibor Blenessy
The call to us.toString()is redundant, toString()method will be called regardless the configured log level. You should pass only usas an argument to infowithout an ifstatement.
调用us.toString()是多余的，toString()无论配置的日志级别如何，都会调用方法。你应该只us作为参数传递给info没有if声明。
logger.info("Log this: {}", us);
回答by Olezt
As stated at the comments of the question, another working answer is:
正如问题的评论中所述，另一个有效的答案是：
if(logger.isInfoEnabled() && us != null){
logger.info("Log this: {}", us.toString());
}
