eclipse中的tomcat，代码中创建file获取目录与tomcat单独运行获取目录不同的解决办法

eclipse tomcat 2017-07-19 21:17:19 810

提示，此代码所在的都是rest接口（web项目）中，而不是在普通的Test类或者是main方法中

重现：

@GET

public Response sayHello(@Context HttpServletRequest request,

@Context HttpServletResponse response){

File file=new File("repository/configuration.xml");

URI uri = file.toURI();

System.out.println(uri);

return Response.ok().status(200).build();

}

返回结果为：

file:/E:/works/eclipse-jee-mars-2-win32-x86_64/eclipse/repository/configuration.xml

而我要获取的是tomcat下的目录，如我上端代码，直接启动tomcat运行获取到的是：

file:/N:/works/IDE/apache-tomcat-7.0.54-windows-x86/apache-tomcat-7.0.54/bin

那么就要修改配置，让在eclipse中也获取此目录

解决办法：

1、双击Servers下的tomcat

2、将会打开eclipse中的tomcat配置界面，然后点击“Open launch configuration”

3、打开标签页Arguments，选择“Working directory“为Other，填入如下值：

N:\works\IDE\apache-tomcat-7.0.54-windows-x86\apache-tomcat-7.0.54\bin

然后保存即可

如图：

修改过后，再在eclipse中启动tomcat，运行此代码获取到的就是和tomcat运行时获取的目录相同了

file:/N:/works/IDE/apache-tomcat-7.0.54-windows-x86/apache-tomcat-7.0.54/bin

eclipse安装nodejs插件nodeclipse

eclipse nodejs nodeclipse 插件 2017-07-19 20:18:26 1109

最近参与前端开发任务，用到nodejs，虽然公司同事都用webstorm，自己也用了，但是总感觉不顺手，可能是常年使用eclipse开发有关（这里不讨论最佳开发工具，自己顺手才是王道），于是自己想要使用eclipse开发nodejs项目，想到之前听说的nodeclipse，就去官网看了下，安装步奏还是挺方便的，安装后初步试用了下，感觉挺顺手的

1、安装nodejs
2、安装jdk，配置eclipse，这里我用的是eclipse 4.5.2
3、下载nodeclipse离线安装包：
http://nchc.dl.sourceforge.net/project/nodeclipse/update-site-archive/org.nodeclipse.site-1.0.2-201509250223.zip
或者
http://pan.baidu.com/s/1dFiF7IL

4、安装nodeclipse，help-->Install New Software，如下图选择下载的压缩包

选择插件：

5、完成以上步奏即完成了安装

更多安装方式还请参考如下地址：
