Tomcat:如何在 Netbeans 中设置 Java 系统属性?

Tomcat: How do I set up a Java system property in Netbeans?(Tomcat:如何在 Netbeans 中设置 Java 系统属性?)

问题描述

我如何从 Netbeans 中为 Tomcat 设置一个我可以使用 System.getProperty(...);

How do I, from Netbeans, for use with Tomcat, set up an environment variable that I can read using System.getProperty(...);

我们有一个源代码控制项目 - 我们不断对我们愿意"分享的确认进行更改(不想使用 svn:ignore).我们正在尝试设置一个简单的参数，即应用程序配置属性的环境变量.例如:mark.properties 或 john.properties.如果系统找不到环境变量，则默认为 server.properties(用于实时系统).

We have a source controlled project - and we're constantly making changes to confirurations that we "would" like to share (don't want to use svn:ignore). We're trying to set up one simple parameter, an environment variable to the config properties of our application. For example: mark.properties or john.properties. If the system can't find the environment variable, then it defaults to server.properties (for the live system).

推荐答案

1.转到 Tomcat 属性平台设置

<强>2.在 VM 选项下，添加 -Dvariable=value

将 D 保留在原位，并用您想要设置的任何变量名称替换该变量，并为您想要设置该变量的任何值赋值.

Leave the D in place, and replace the variable with whatever variable name you'd like to set and value whatever value you'd like to set the variable to.

3.从您的代码中读出属性.

System.out.println("The value is " + System.getProperty("variable"));
