我已经编写了一个java代码,它在eclipse上运行良好并读取了所有必要的文件。
该项目包含一个属性文件和一个用作图标的 png 图像。
之后,我在 build.xml 中为其创建了一个构建脚本。
使用 ant 构建工具已成功编译构建。
当我执行 jar 时,它没有加载我的图像和属性文件。

.properties 文件
keyStorePassword=pass.dat
keyStoreKey=key.dat
#keyStorePassword=C:\\Users\\imjme1\\Desktop\\Work_backup\\FMS\\EPM_FILE_ENCRYPTION\\NIFT_SOLUTION\\files\\keyStorePass.dat
#keyStoreKey=C:\\Users\\imjme1\\Desktop\\Work_backup\\FMS\\EPM_FILE_ENCRYPTION\\NIFT_SOLUTION\\files\\keyStoreKey.dat
加载图片
// Set the icon of the utility..
ImageIcon icon = new ImageIcon(this.getClass().getResource( "keyicon.png" ) );
Image image = icon.getImage();
Image scaledImage = image.getScaledInstance(120, 120, java.awt.Image.SCALE_SMOOTH); // scale it the smooth way
frame.setIconImage( scaledImage );
读取.properties文件
public static String configFile;
public static CommonUtil config;
public static String propertyFileName = "/encryption.properties";
public static Properties properties = new Properties();
// static block to load the property file and assign values from it..
static {
config = new CommonUtil();
try {
config.init(propertyFileName);
} catch (Exception io) {
io.printStackTrace();
}
}
// Initialize the variables for key store credentials and set values from config file..
public void init( String configFileName ) throws Exception {
CommonUtil.configFile = configFileName;
InputStream configFile = CommonUtil.class.getResourceAsStream( configFileName );
properties.load( configFile );
keyStorePass = properties.getProperty( "keyStorePassword" );
keyStoreKey = properties.getProperty( "keyStoreKey" );
}
Build.properties 文件
src.dir=C:/Users/imjme1/fms-file-encrytion/RTA_ENCRYPTION_UTILITY/src
build.dir=${basedir}/build
deploy.dir=${basedir}/deploy
lib.path.all=${basedir}/libs
最佳答案
您可以将所有资源文件保存在jar的pwd中。
例如,我正在从 build.xml 中读取 build.properties 的属性,所以我的目录结构将是:
.
myapp.jar
build.xml
build.properties
关于java - 可执行 jar 不读取 .properties 文件 (Build.xml),我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/61287387/
