1. 基础配置
1.1.设置字体和颜色
操作步骤：Window -> Preferences -> General -> Appearance -> Colors and Fonts -> Basic--> Text Font --> Edit
1.2.代码自动提示
如果项目工程中没有web.xml文件，可以手动动态添加。
操作步骤：Window -> Preferences -> Java -> Editor -> Content Assist -> Auto-Activation
将 Auto activation triggers for java 修改为：.abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
1.3.关闭拼写检查
操作步骤：Window -> Preferences -> General–>Editors–>Text Edittors–>spelling，取消勾选
1.4.关闭validation语法校验
操作步骤：Window -> Preferences -> Validation，其中 Manual 表示手动校验，Build 表示生成时自动校验，基本上 Build 下所有都可以关闭。
1.5.修改工作空间默认编码
操作步骤：Window -> Preferences -> General--> Workspace -> Other，修改为：UTF-8
1.6.properties文件中文乱码设置
Eclipse打开properties文件时，中文会显示乱码，这是因为properties文件默认编码方式是iso8859-1，将其修改为utf-8后，就可以正常显示了
操作步骤：Window -> Preferences -> General -> Content Types -> Text -> Java Properties File -> UTF-8 -> Update -> OK
1.7.配置Maven
在下载Maven并设置好本地仓库和远程仓库等配置后，就可以在Eclipse中配置Maven。
操作步骤：Window -> Preferences -> Maven -> User Settings
1.8.配置Tomcat
需要下载Tomcat并配置好相关端口等信息后，按如下步骤操作。
操作步骤：Window -> Preferences -> Server -> Runtime Environment
1.9.编辑器代码折叠配置
操作步骤：Window -> Preferences -> Java -> Editor -> Folding
1.10.安装主题插件 - DevStyle
操作步骤：Help -> Eclipse Marketpalce -> Search -> DevStyle
2. Eclipse 个人喜欢的格式化配置
格式化整个项目代码：右键项目 -> Source -> Format
个人配置文件

3. Eclipse 中一个普通 JavaWeb 项目的目录结构
如果项目工程中没有web.xml文件，可以手动动态添加。
右击项目 -> java EE Tools -> Genertate Deployment Descriptor Stub
4. 在 Eclipse 中查看 JDK 某个类的源码
在 Eclipse 中，按住 Ctrl 键并点击某个类或对象，就会跳转到该类或对象的定义。如果是 JDK 中的某个类，则会显示如下
这是因为在Eclipse中需要进行相关配置，才能查看相关的源码
4.1：点击 "window" -> "Preferences" -> "Java" -> "Installed JRES" -> "对应版本的jre" -> "Edit"
4.2：选中 rt.jar -> 点右边的按钮 "Source Attachment..."
4.3：选择 JDK 安装目录下的 src.zip 文件
4.4：然后在查看 "System.out.println("");" 中的 System 类，就可以看到源码了。
