[英]save user status in maven project
I am writing a javaFX project with netbeans IDE and maven. 我正在用netbeans IDE和maven编写一个javaFX项目。
I am saving user edits in a property file and i loading it when the application start up and i want to update it when application shuts down to reuse it next time. 我将用户编辑保存在属性文件中,并在应用程序启动时加载它,我想在应用程序关闭时更新它,以备下次使用。
So I am reading the property file as below: 所以我正在读取属性文件,如下所示:
public static Properties propConfig = new Properties();
InputStream input;
input = Config.class.getClassLoader().getResourceAsStream("config/displayConfig.properties");
propConfig.load(input);
which works fine.. 效果很好..
but i don't know how to update the property file :( as 但我不知道如何更新属性文件:(作为
output = new FileOutputStream( new File(Config.class.getClassLoader().getResource("config/displayConfig.properties").toURI()) );
is not working since it reads the resource file from jar 无法工作,因为它从jar读取资源文件
jar:file:/D:/freelance%20projects/01%20school%20tool%20bar/mavenprojectFX/target/racer40-1.0-SNAPSHOT.jar!/config/displayConfig.properties
Normally it's not recommended to update files in JARs. 通常,不建议在JAR文件中更新文件。 Use local files instead, eg: 请改用本地文件,例如:
Path userDirPath = Paths.get(System.getProperty("user.home"), ".<myAppSymbolicName>", "<myAppVersion>");
Path configDirPath = userDirPath.resolve("config");
Path displayConfigFilePath = configDirPath.resolve("displayConfig.properties");
// read file
well i have done a workaround, since I can only read files from jar i have defined a new properties file and i have defined the configuration path in it. 好吧,我做了一个变通办法,因为我只能从jar中读取文件,所以我定义了一个新的属性文件,并且在其中定义了配置路径。
i have modified resources in POM.xml to set filtering true 我已经在POM.xml中修改了资源以将过滤设置为true
<resources>
<resource>
<directory>src/main/resources</directory>
<filtering>true</filtering>
</resource>
</resources>
i have placed the path property file in "src/main/resources/config" folder 我已经将路径属性文件放在“ src / main / resources / config”文件夹中
the path file contains 路径文件包含
Path=${project.build.directory}
and i am reading it as the following 我正在阅读以下内容
InputStream pathStream
= Config.class.getClassLoader().getResourceAsStream("config/path.properties");
Properties pathProperties = new Properties();
pathProperties.load(pathStream);
path = pathProperties.get("Path").toString().replace("target", "");
System.out.println(pathProperties.get("Path"));
pathStream.close();
then i am using 'path' variable as the following 然后我正在使用'path'变量,如下所示
OutputStream output = new FileOutputStream(new File(path + displayConfig.properties"));
so I am now putting the configuration file "displayConfig.properties" in the same path of jar. 所以我现在将配置文件“ displayConfig.properties”放在jar的相同路径中。
