是否可以在maven中设置可从java类中获得的系统属性。
我已经看到在surefire插件中这是可能的(here),如下所示;
String param = System.getProperty("my_parameter1");
<configuration>
<systemPropertyVariables>
<my_property1>${my_property1}</my_property1>
</systemPropertyVariables>
</configuration>
但是我想了解我正在处理的环境,我已经将prod或dev作为maven profile参数传递 - 是否有可能通过设置变量来获取代码中的句柄在我调用的配置文件中,然后调用system.getProperty或其他方式?
由于
我的pom文件

您应该查看exec-maven-plugin。
使用以下配置(注意<systemProperties>
)...
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.3.2</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>java</goal>
</goals>
</execution>
</executions>
<configuration>
<mainClass>com.example.Main</mainClass>
<arguments>
<argument>argument1</argument>
</arguments>
<systemProperties>
<systemProperty>
<key>hello.world</key>
<value>Hello Stack Overflow!</value>
</systemProperty>
</systemProperties>
</configuration>
</plugin>
......以及以下课程......
package com.example;
public class Main {
public static void main(String[] args) {
String prop = System.getProperty("hello.world");
System.out.println(prop);
}
}
...并运行package
(注意配置中的阶段 - 您可以根据需要进行更改,也许可以安装),它会从密钥{{1中打印出值Hello Stack Overflow!
}}。所以基本上,插件在你构建时会执行你的程序。
另见exec:exec
目标。在示例中,我使用了exec:java
目标,但两者在功能上有所不同。
exec:exec
在一个单独的过程中执行程序和Java程序。
exec:java
在同一个VM中执行Java程序。

目前我正在根据myven pom文件中的配置文件在属性中设置一些值。是否可以在配置文件中设置此系统属性?因为实际上,我只有一个用于dev和prod的pom文件,而且我需要设置它。
是的,只需使用系统属性元素的hello.world
元素中的${property.name}
即可。例如:
<value>
插件<profiles>
<profile>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<id>world</id>
<properties>
<hello.world>Hello World!</hello.world>
</properties>
</profile>
<profile>
<activation>
<activeByDefault>false</activeByDefault>
</activation>
<id>stack</id>
<properties>
<hello.world>Hello Stack Overflow</hello.world>
</properties>
</profile>
</profiles>
:
<systemProperties>
只需将个人资料更改为<systemProperties>
<systemProperty>
<key>hello.world</key>
<value>${hello.world}</value>
</systemProperty>
</systemProperties>
或stack
,邮件就会分别打印world
或Hello Stack Overflow
。
更新2
另一个插件是properties-maven-plugin。在一段时间内没有做任何事情,但是通过一些测试,必要的功能就在那里。
它有一个set-system-properties
目标以及其他一些useful goals来帮助简化物业管理
Hello World
