如果我从命令行执行以下命令 -
,如何使用核心java加载属性文件css_content = get_inline_content_and_remove_tags(webpage_content, 'style')
js_content = get_inline_content_and_remove_tags(webpage_content, 'script')
webpage_content = # ...clean cruft...
def copy_paste_to_hidden_element(content=None, html_id=None):
pyperclip.copy(content)
activate_hidden_element(html_id=html_id, driver=driver)
call_sp('xdotool key from+ctrl+v')
time.sleep(1)
copy_paste_to_hidden_element(content=webpage_content, html_id="panel_html")
copy_paste_to_hidden_element(content=js_content, html_id="panel_js")
copy_paste_to_hidden_element(content=css_content, html_id="panel_css")
和在类文件中我使用
mvn clean package exec:java -Dexec.mainClass="com.crossover.trial.properties.Main" -Dexec.args="classpath:resources/jdbc.properties"
它给出了空指针。

答案 0 :(得分:0)
exec:java" -Dexec.args = param1 param2 param3"
所以在你的情况下exec:java" -Dexec.args = classpath:resources / jdbc.properties"
(查看""位置),您将在args [0]获得classpath:resources / jdbc.properties。
答案 1 :(得分:0)
您不需要在命令行上提供任何位置。或者使用" classpath:"启动资源名称。正如您在回答我之前的评论时所述,使用src / main / resources下的属性文件,maven-jar-plugin会将它放在类路径的jar中。
此代码:
package com.crossover.trial.properties;
import java.net.URL;
import java.util.Properties;
public class Main {
public static void main(String[] args) {
Properties prop1 = new Properties();
URL url1 = ClassLoader.getSystemResource("jdbc.properties");
try{
prop1.load(url1.openStream());
}catch(Exception e)
{
e.printStackTrace();
}
System.out.println("------- By Using URL class -------");
System.out.println(prop1);
}
}
会好的。
似乎您还没有在清单中指定主类。要简化命令行,请使用maven-jar-plugin添加它。
你也可以使用maven-antrun-plugin来启动它(因为我在Eclipse下工作,我避免使用exec-maven-plugin,但除此之外它只是一个品味问题):

现在您可以使用以下命令启动jar:
mvn clean package antrun:run -Pjar-launcher
或直接主类,不包装:
mvn clean compile antrun:run -Pclass-launcher
那就是它。
要使用exec-maven-plugin,请添加到pom:
<profile>
<id>jar-exec</id>
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>${maven.exec.plugin.version}</version>

<arguments>
<argument>-classpath</argument>
<classpath />
<argument>${main.class}</argument>
</arguments>
</configuration>
</plugin>
</plugins>
</build>
</profile>
现在您可以使用以下命令启动jar:
mvn clean package exec:exec -Pjar-exec
或直接主类,不包装:
mvn clean compile exec:exec -Pclass-exec
