第一種:
File file=newFile(this.getClass().getResource("/").getPath());
System.out.println(f);
結果:
C:/Documents%20and%20Settings/Administrator/workspace/projectName/bin
獲取當前類的所在工程路徑;
若是不加「/」
File f = new File(this.getClass().getResource("").getPath());
System.out.println(f);
結果:
C:/Documents%20and%20Settings/Administrator/workspace/projectName/bin/com/test
獲取當前類的絕對路徑;java
第二種:
File directory = new File("");//參數爲空
String courseFile = directory.getCanonicalPath() ;
System.out.println(courseFile);
結果:
C:/Documents and Settings/Administrator/workspace/projectName
獲取當前類的所在工程路徑;this
第三種:
URL xmlpath = this.getClass().getClassLoader().getResource("selected.txt");
System.out.println(xmlpath);
結果:
file:/C:/Documents%20and%20Settings/Administrator/workspace/projectName/bin/selected.txt
獲取當前工程src目錄下selected.txt文件的路徑spa
第四種:
System.out.println(System.getProperty("user.dir"));
結果:
C:/Documents and Settings/Administrator/workspace/projectName
獲取當前工程路徑xml
第五種:
System.out.println( System.getProperty("java.class.path"));
結果:
C:/Documents and Settings/Administrator/workspace/projectName/bin
獲取當前工程路徑get
