为什么 Eclipse - Tomcat 7 在控制台中以红色显示所有文本

Question

我在 Tomcat 7 中使用 Eclipse Kepler，我只是在测试一个简单的 JSP 页面 (test.jsp)。它在浏览器中运行良好，但控制台中的所有文本都显示为红色。

我检查了 Window/Preferences/(Run/Debug) 属性，所有接缝都没有问题。

来自控制台的文本如下：

是项目有问题还是有办法将文本显示为黑色（只是错误显示为红色）？非常感谢！！

Answer 1

红色文本正在写入 System.err 流，黑色文本正在写入 System.out。没有什么本质上是错的，这就是系统区分输出流的方式。您可以通过右键单击控制台并选择 "Preferences"

来根据自己的喜好配置显示
