推荐答案

引用文档:

添加 GWT 日志真的很简单，就像下面的代码示例一样简单.然而——了解日志记录的工作原理，以及如何正确配置它很重要，所以请花点时间阅读本文档的其余部分.

Adding GWT logging is really quite simple, as simple as the following code example. However — understanding how logging works, and how to correctly configure it is important, so please do take the time to read the rest of this document.

启用日志记录的最简单方法是:

The simplest way to enable logging is:

# In your .gwt.xml file
<inherits name="com.google.gwt.logging.Logging"/>

# In your .java file
Logger logger = java.util.logging.Logger.getLogger("NameOfYourLogger");
logger.log(Level.SEVERE, "this message should get logged");
