在Maven中创建由Maven-archetype-quickstart创建的Java项目中的属性文件 [英] Reading Properties file in Maven Java Project created by maven-archetype-quickstart

问题描述

 （properties = new Properties（））。load（DbCopy.class.getClassLoader（）
 .getResourceAsStream（config.properties））; 
  

它会抛出异常：

 线程中的异常mainjava.lang.NullPointerException 
在java.util.Properties.load（Properties.java:284）
 at benz.bnp.db.DbCopy .main（DbCopy.java:77）
  

感谢您的帮助！

解决方案

如果目标文件夹包含属性文件，请查看目标文件夹。希望它不会包含。要包括您的属性文件，请修改您的pom：

 < build> 
< resources> 
< resource> 
< directory> $ {project.basedir} / src / main / java< / directory> 
< filtering> true< / filtering> 
< includes> 
< include> ** / *。properties< / include> 
< / includes> 
< / resource> 
< / resources> 
< / build> 
  

将其添加到您的POM.xml并为您的属性文件配置相同。

I'm trying to read a properties file using the below code on a Java Project created using Maven ArchetypeId=maven-archetype-quickstart

(properties = new Properties()).load(DbCopy.class.getClassLoader()
   .getResourceAsStream("config.properties"));

And it throws exception:

Exception in thread "main" java.lang.NullPointerException
  at java.util.Properties.load(Properties.java:284)
  at benz.bnp.db.DbCopy.main(DbCopy.java:77)

Thanks for helping !

解决方案

Have a look at the target folder, if it contains your properties file. Hopefully it will not contain. To include your property file edit your pom:

<build>        
<resources>
                        <resource>
                            <directory>${project.basedir}/src/main/java</directory>
                            <filtering>true</filtering>
                            <includes>
                                <include>**/*.properties</include>
                            </includes>
                        </resource>
     </resources>
</build>

Add it to your POM.xml and configure the same for your properties file.
