Window -> Preferences -> General -> Appearance -> Colors and Fonts -> Java -> Java Editor Text Font -> Edit；
调节控制台字体：
Window -> Preferences -> General -> Appearance -> Colors and Fonts -> Basic -> Text Font -> Edit

调节jsp字体
Window -> Preferences -> General -> Appearance -> Colors and Fonts ->Structured Text Editors->Structured->Edit
