Spring应用程序属性配置文件与war文件

Question

我正在尝试将我的项目打包到.war一个tomcat服务器部署中.我需要用我的能力application.properties OR application-dev.properties 或 appliation-qa.properties OR application-prod.properties.使用嵌入的servlet运行项目我可以通过命令行指定我想要使用的项目,但是,application.properties当我将它打包为一个项目时,项目总是使用.war.

我使用以下命令在本地运行我的项目:

1. mvn spring-boot:run
2. mvn spring-boot:run -Drun.arguments="--spring.profiles.active=dev"

这个命令将我的项目打包成竹子进行部署:

• mvn package -Dspring.profiles.active=qa

Application.java

    package com.pandera.wilson;

    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.boot.builder.SpringApplicationBuilder;
    import org.springframework.boot.context.web.SpringBootServletInitializer;
    import org.springframework.context.annotation.ComponentScan;
    import org.springframework.core.env.AbstractEnvironment;
    import org.springframework.scheduling.annotation.EnableAsync;
    import org.springframework.scheduling.annotation.EnableScheduling;

    import javax.servlet.ServletContext;
    import javax.servlet.ServletException;

    import org.apache.log4j.Logger;

    /**
     * @author Gaurav Kataria
     * @author Austin Nicholas
     * @category Application
     */

    @SpringBootApplication
    @ComponentScan(basePackages = { "com.pandera.wilson" })
    @EnableAsync
    public class Application extends SpringBootServletInitializer {

        static final Logger logger = Logger.getLogger(Application.class);

        public static void main(String[] args) throws Exception {

            logger.info("Entering Application");
            SpringApplication.run(Application.class, args);
        }

        @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
            return application.sources(Application.class);
        }

    }

我已经将以下内容添加到我的pom.xml中并尝试打包mvn package -P PROD,但是,当我点击时,/about我仍然看到我正在使用appliation.properties而不是application-prod.properties.

<profiles>
    <profile>
        <id>QA</id>
        <properties>
            <spring.profiles.active>qa</spring.profiles.active>
        </properties>
    </profile>

    <profile>
        <id>DEV</id>
        <properties>
            <spring.profiles.active>dev</spring.profiles.active>
        </properties>
    </profile>

    <profile>
        <id>PROD</id>
        <properties>
            <spring.profiles.active>prod</spring.profiles.active>
        </properties>
    </profile>
</profiles>

Answer 1

您可以通过以下方式定义弹簧轮廓:

web.xml中

<context-param>
 <param-name>spring.profiles.active</param-name>
 <param-value>your target profile here</param-value>
</context-param>

setenv.sh

在Tomcat的bin文件夹下,使用以下内容创建setenv.sh文件:

JAVA_OPTS="$JAVA_OPTS -Dspring.profiles.active=<your target profile here>"

Answer 2

要根据预定义的配置文件打包项目，您需要执行以下操作：

1. 在您的application.properties, 添加

   spring.profiles.active=@spring.profiles.active@

2. 在您的 POM 中，添加以下内容：

<build>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering>
        </resource>
    </resources>

3. 并定义您的个人资料（就像您所做的那样）

4. 运行命令 mvn package -P QA

您会看到在生成的 WAR 中，application.properties,spring.profiles.active=@spring.profiles.active@将被替换为spring.profiles.active=QA

Answer 3

你试过这个吗？

java -jar -Dspring.profiles.active=qa yourwarfilename.war

对于打包，您可以创建这样的配置文件，并在通过 $mvn package -P QA 构建它时调用此配置文件：

<profiles>
  <profile>
    <id>QA</id>
    <properties>
      <spring.profiles.active>qa</spring.profiles.active>
    </properties>
  </profile>
</profiles>
