Spring引导应用程序作为服务

如何在Linux系统中将Spring Boot应用程序打包为可执行jar as a Service ?这是推荐的方法吗，还是应该将这个应用程序转换为war并将其安装到Tomcat中?

目前，我可以从屏幕会话运行Spring引导应用程序，这很好，但需要在服务器重新启动后手动启动。

我正在寻找的是一般的建议/方向或样本init。D脚本，如果我的方法与可执行jar是适当的。

我的SysVInit脚本Centos 6 / RHEL(还不理想)。这个脚本需要ApplicationPidListener。

/etc/init.d/app的源代码

配置文件/etc/sysconfig/app示例:

如果你想使用Spring Boot 1.2.5和Spring Boot Maven Plugin 1.3.0。M2，这是我们的解

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.2.5.RELEASE</version>
</parent>

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <version>1.3.0.M2</version>
            <configuration>
                <executable>true</executable>
            </configuration>
        </plugin>
    </plugins>
</build>

<pluginRepositories>
    <pluginRepository>
        <id>spring-libs-milestones</id>
        <url>http://repo.spring.io/libs-milestone</url>
    </pluginRepository> 
</pluginRepositories>

然后像往常一样编译:mvn清洁包，做一个符号链接ln -s /…/myapp.jar /etc/init.chmod +x /etc/init. D /myapp，使其可执行启动myapp服务(Ubuntu服务器)

I don't know of a "standard" shrink-wrapped way to do that with a Java app, but it's definitely a good idea (you want to benefit from the keep-alive and monitoring capabilities of the operating system if they are there). It's on the roadmap to provide something from the Spring Boot tool support (maven and gradle), but for now you are probably going to have to roll your own. The best solution I know of right now is Foreman, which has a declarative approach and one line commands for packaging init scripts for various standard OS formats (monit, sys V, upstart etc.). There is also evidence of people having set stuff up with gradle (e.g. here).

我最终为WAR/JAR布局做了systemd服务

我调用java -jar是因为它更灵活。我还试着把ExecStart=spring-mvc。战争，但即使是可执行的，我得到'Exec格式错误'

无论如何，现在systemd出现在所有发行版上，并提供了一个很好的解决方案来重定向日志(syserr是重要的，当你的服务甚至没有启动log4j文件位置将为空:))。
