WARN No appenders could be found for logger (org.springframework.test.context.junit4.SpringJUnit4ClassRunner)

在这个问题中，报错信息显示为"WARN No appenders could be found for logger (org.springframework.test.context.junit4.SpringJUnit4ClassRunner)"。这个错误提示说明在Spring测试中找不到与日志记录器相关联的附加器。根据引用的错误日志，我们可以推断这个问题可能是由于缺少适当的log4j配置文件引起的。为了解决这个问题，我们可以按照引用中提供的log4j.properties文件的配置，将其添加到工程的target/classes文件夹下。这样，log4j就能够正常地初始化并配置日志记录器，使得报错信息消失。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
