springboot打jar包运行在linux并指定日志输出

1.创建maven工程springboot-jar

2.在pom.xml指定打包方式为jar

    <groupId>com.test</groupId>
    <artifactId>springboot-jar</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>jar</packaging>

2.在pom.xml引入springboot依赖

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
            <version>2.1.8.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
            <version>2.1.8.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <version>2.1.8.RELEASE</version>
        </dependency>
    </dependencies>

4.指定maven打包插件

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
                <encoding>UTF-8</encoding>
            </configuration>
        </plugin>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <version>2.1.8.RELEASE</version>
            <configuration>
                <includeSystemScope>true</includeSystemScope>   //解决scope为system的jar包无法被打包进jar文件
                <mainClass>com.test.Application</mainClass>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

5.controller测试类

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author c
 * @date 2020/5/14 9:59
 */
@RestController
public class TestController {

    @RequestMapping("/helloworld")
    public String hello(String name) {
        return "name" + name;
    }

}

6.启动类Application

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.Banner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @author c
 * @date 2020/5/14 10:00
 */
@SpringBootApplication
public class Application {

    private static final Logger LOG = LoggerFactory.getLogger(Application.class);

    public static void main(String[] args) {
        SpringApplication app = new SpringApplication(Application.class);
        app.setBannerMode(Banner.Mode.OFF);
        app.run(args);
        LOG.info("**************** Startup Success ****************");
    }

}

7.application.yml配置文件

server:
  port: 7070
  session-timeout: 0
  context-path: /

8.打包测试运行

idea右上角Maven--Lifecycle--package,在项目target目录下生成两个jar文件,一个是加载maven依赖另一个没有加载,

我们选择springboot-jar-1.0-SNAPSHOT.jar上传到linux目录下.

启动项目:java -jar springboot-jar-1.0-SNAPSHOT.jar 但是关闭窗口项目就停止了

后台启动项目:nohup java -jar springboot-jar-1.0-SNAPSHOT.jar &   关闭窗口不会停止项目,还会在当前目录生成nohup.out日志文件

                      nohup java -jar springboot-jar-1.0-SNAPSHOT.jar > 日志文件名.log 2>&1 &  指定生成的日志文件名

                      nohup java -jar springboot-jar-1.0-SNAPSHOT.jar >/dev/null 2>&1 &  标准输出和错误输出都丢弃
