Eclipse Jee 2019-12 使用的一些小窍门（积累性更新)

在安装使用 Eclipse IDE for Enterprise Java Developers  Version: 2019-12 M1 (4.14.0) 之前请确保已在系统环境变量配置好JDK1.8+

1.   Eclipse官方下载安装

https://www.eclipse.org/downloads/ 

下载eclipse javaEE开发环境，初次运行会让你确定自己的工作区，工作区是你创建project工程的地方，选择一个容易找到的目录作为你的工作区，工作区目录不要设在中文目录中，win10系统的Eclipse工作区的默认位置在

C:Userskangyeclipse-workspace

2.   添加系统中的JDK

Windows——>Preferences——>Installed JREs

3.   eclipse添加代码提示功能

.abcdefghijklmnopqrstuvwxyz

4.   导入formatter模板

4.1. 修改字体

 

4.2. 更改主题

4.3. 关闭自动更新

4.4 调整左侧Project Explorer树显示的内容分类

5.   修改IDE编码格式

5.1. 修改workspace编码为UTF-8

5.2. 修改jsp编码为UTF-8

5.3. 修改.properties配置文件UTF-8

在中文操作系统中，Eclipse中的Java类型文件的编码的默认设置是GBK，但是对Properties资源文件的编码的默认设置是ISO-8859-1。

找到Text类型下面的Java Properties File类型的文件，选中后下面会有 默认的字符编码，手动输入UTF-8，然后update，接着ok即可以后中文编辑不乱码。

6. Eclipse的一些常用快捷键（主要是和IDEA不同的设定）

Eclipse快速添加get、set方法

在合适的地方采用快捷键 Shift+Alt+S 

 

Eclipse 的快键键与搜狗输入法有冲突，中文状态下快速格式化代码的方法

Ctrl + D 删除光标所在的一行代码

Alt + Shift + Z  快速添加 try catch

7、Eclipse执行maven install命令时跳过test步骤

install -DskipTests

    <build>
        <plugins>

            <!-- eclipse执行maven install命令时跳过test -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.22.2</version>
                <configuration>
                    <skip>true</skip>
                </configuration>
            </plugin>
        </plugins>
    </build>

8.在Eclipse里配置外部Maven(maven要先配置好系统环境变量Path ，mvn -v显示版本号）

8.使用Eclipse打断点debug我们的 项目

快捷键F6步进调试，可以鼠标悬停查看变量是否为null

9. 如何在eclipse中添加dtd文件

Eclipse中配置使用本地schema或dtd文件

10.Eclipse 安装阿里巴巴规约插件方法

首先点击help里面的“install new sotfware”；

在work with 一栏输入：https://p3c.alibaba.com/plugin/eclipse/update

勾选搜索到的插件，点击next安装即可。

Eclipse插件的卸载详解

11.用JAVA选项卡的Tasks列表查询TODO

 

Elicpse使用技巧-打开选中文件文件夹或者包的当前目录
