SpringBoot 2.x项目jar包部署

### 1、修改pom.xml ###

修改两处：  
（1）修改maven中的package方式为jar

（2）修改`<build></build>`

<build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                    <configuration>
                        <mainClass>cn.hadron.db.DbApplication</mainClass>
                    </configuration>
                    <executions>
                        <execution>
                            <goals>
                                <goal>repackage</goal>
                            </goals>
                        </execution>
                    </executions>
                </plugin>
            </plugins>
        </build>

如果此处不指定mainClass的话，很有可能就是项目可以打包成功，并且可以java -jar \*.jar成功启动，但是访问不了任何服务。

### 2、打包 ###

进到此项目的根目录，即pom.xml所在文件目录

mvn clean package

### 3、启动jar包 ###

进入到jar所在目录位置，使用java -jar \*.jar启动

...\target>java -jar db-0.0.1-SNAPSHOT.jar

### 4、页面访问 ###

### 5、Linux服务器后端运行jar ###

[root@node opt]# nohup java -jar db-0.0.1-SNAPSHOT.jar > /tmp/db.log &
    [1] 31334
    [root@node opt]# nohup: ignoring input and redirecting stderr to stdout

### 6、Linux查看jar进程 ###

[root@node ~]# ps -ef | grep .jar
    root      5565     1  0 Feb28 ?        00:01:38 java -jar db-0.0.1-SNAPSHOT.jar
    root     26647 12566  0 09:49 pts/0    00:00:00 grep --color=auto .jar
    [root@node ~]#
