详细过程：

下载安装好Eclipse后，

1.在Eclipse中菜单help选项中选择install new software选项

2.在work with 栏中输入 Juno - http://download.eclipse.org/releases/juno

补充详细过程如下图：

点击next后会等待比较长的时间，直到出现下面的界面：

3.拉到后面选择Web, XML, Java EE and OSGi Enterprise Development选项（此处根据实际项目内容自行选择或查找），然后选择

Eclipse Java EE Developer Tools
Eclipse Java Web Developer Tools
Eclipse Web Developer Tools
Eclipse XML Editors and Tools
JST Server Adapters and JST Server Adapters Extensions
注：上述选择仅为原作者的选择，与本文中选择不同，本文选择见后图中的Will be installed的内容。

界面如下：该过程也要等待一段时间。

有一个小插曲，有些选项只能选择一个版本，有的之前已经安装过，所以不是所有选项都安装成功。

安装成功
Next到最后，accept，finish。

eclipse界面在安装完成前不要关闭，右下角会显示install的进度。安装完毕后会提示重启生效。

4.打开Eclipse->Window->Preferences
可以看到左边有Java、Java EE、JavaScript、Web、Web Services，说明成功安装了Developer Tools。

点击Java，检查一下Installed JREs中的路径是否正确。
若为空，需要下载jre并加载路径。（此处已经下载好）加载路径：Add->默认下载的jre路径是 C:\Program Files\Java\jre1.8.0_251(写在Add->JRE home)->finish->Apply and Close。

到这里windows下eclipse+java开发环境就配置好了
