# spring-boot-assembly

> 1. 在spring boot项目中使用maven profiles和maven assembly插件根据不同环境打包成tar.gz或者zip
> 2. 将spring boot项目中的配置文件提取到外部config目录中
> 3. 将spring boot项目中的启动jar包移动到boot目录中
> 4. 将spring boot项目中的第三方依赖jar包移动到外部lib目录中
> 5. bin目录中是启动，停止，重启服务命令
> 6. 打包后的目录结构类似于tomcat/maven目录结构

##### window启动,会打开浏览器，访问项目测试路径

```bash
bin/startup.bat
```
> - 访问地址: [http://localhost:8080/example/hello?name=123](http://localhost:8080/example/hello?name=123)
> - 响应结果: 
```json
{"msg":"service hello:123","code":200}
```

##### linux启动，停止，重启

```bash
sh bin/startup.sh   启动项目
sh bin/shutdown.sh  停止服务
sh bin/restart.sh   重启服务
```

##### startup.sh 脚本中的主要内容
- 配置项目名称及项目启动jar名称，默认项目名称与启动jar名称一致

```bash
APPLICATION="spring-boot-assembly"
APPLICATION_JAR="${APPLICATION}.jar"
```

- JAVA_OPTION配置
> - JVM Configuration
> - -Xmx256m:设置JVM最大可用内存为256m,根据项目实际情况而定，建议最小和最大设置成一样。
> - -Xms256m:设置JVM初始内存。此值可以设置与-Xmx相同,以避免每次垃圾回收完成后JVM重新分配内存
> - -Xmn512m:设置年轻代大小为512m。整个JVM内存大小=年轻代大小 + 年老代大小 + 持久代大小。持久代一般固定大小为64m,所以增大年轻代,将会减小年老代大小。此值对系统性能影响较大,Sun官方推荐配置为整个堆的3/8
> - -XX:MetaspaceSize=64m:存储class的内存大小,该值越大触发Metaspace GC的时机就越晚
> - -XX:MaxMetaspaceSize=320m:限制Metaspace增长的上限，防止因为某些情况导致Metaspace无限的使用本地内存，影响到其他程序
> - -XX:-OmitStackTraceInFastThrow:解决重复异常不打印堆栈信息问题

```bash
JAVA_OPT="-server -Xms256m -Xmx256m -Xmn512m -XX:MetaspaceSize=64m -XX:MaxMetaspaceSize=256m"
JAVA_OPT="${JAVA_OPT} -XX:-OmitStackTraceInFastThrow"
```
#### 执行启动命令：后台启动项目,并将日志输出到项目根目录下的logs文件夹下

```bash
nohup java ${JAVA_OPT} -jar ${BASE_PATH}/boot/${APPLICATION_JAR} --spring.config.location=${CONFIG_DIR} > ${LOG_PATH} 2>&1 &
```

## 最终执行jar包的命令

```bash
nohup java -server -Xms256m -Xmx256m -Xmn512m -XX:MetaspaceSize=64m -XX:MaxMetaspaceSize=256m -XX:-OmitStackTraceInFastThrow -jar /opt/spring-boot-assembly/boot/spring-boot-assembly.jar --spring.config.location=/opt/spring-boot-assembly/config/ > /opt/spring-boot-assembly/logs/spring-boot-assembly.log 2>&1 &
```
> - nohup：在后台运行jar包，然后将运行日志输出到指定位置
> - -server：指定JVM参数
> - -jar /opt/spring-boot-assembly/boot/spring-boot-assembly.jar：指定启动的jar包
> - 启动命令中指定的启动jar包路径，配置文件路径，日志路径都是绝对路径
> - 可在任何位置执行start.sh,shutdown.sh,restart.sh脚本
> - --spring.config.location：指定配置文件目录或者文件名称，如果是目录，以/结束 
> - &gt; /opt/spring-boot-assembly/logs/spring-boot-assembly.log：指定日志输出路径
> - 2>&1 & ：将正常的运行日志和错误日志合并输入到指定日志，并在后台运行

#### shutdown.sh停服脚本，实现方式：找到当前项目的PID，然后kill -9

```bash
PID=$(ps -ef | grep "${APPLICATION_JAR}" | grep -v grep | awk '{ print $2 }')
kill -9 ${PID}
```

#### 日志记录
##### 项目启动日志存储路径，一个项目只有一个启动日志文件

```bash
logs/spring-boot-assembly_startup.log
```

```text

application pid: 11596
```

##### 项目运行日志存储路径，最近一次启动项目的运行日志

```bash
logs/spring-boot-assembly.log
```

##### 项目历史运行日志存储路径，每启动一次项目，会将之前的运行日志移动到back目录
```text
`-- logs
    |-- back
    |   |-- spring-boot-assembly_back_2018-12-12-23-30-10.log
    |   `-- spring-boot-assembly_back_2018-12-12-23-36-56.log
    |-- spring-boot-assembly.log
    `-- spring-boot-assembly_startup.log
```
    
#### maven项目打包
##### 1. 使用IDEA工具打包,选择对应的profiles,然后clean package
![mvn-clean-package-local](https://raw.githubusercontent.com/geekidea/spring-boot-assembly/master/img/mvn-clean-package-local.png)
![mvn-clean-package-dev](https://raw.githubusercontent.com/geekidea/spring-boot-assembly/master/img/mvn-clean-package-dev.png)

##### 2. 使用maven命令打包

```bash
mvn clean package -Pdev
```
##### 3. 使用mvn-package脚本打包
> window

```bash
mvn-package.bat dev
```

> linux/mac

```bash
sh mvn-package.sh dev
```

#### FAQ
##### Q: 项目打成tar包后，不能正常读取resource目录下的某些配置文件

##### A:如果resource目录中还用到其它配置文件，需要在pom.xml和assembly.xml文件的resource中进行配置
1. pom.xml中的resource默认配置
> 把需要打包的文件添加到include中

```xml

<resource>
    <directory>src/main/resources</directory>
    <filtering>true</filtering>
    <includes>
        <include>application.yml</include>
        <include>application-${profileActive}.yml</include>
        <include>mapper/**/*.xml</include>
        <include>static/**</include>
        <include>templates/**</include>
        <include>*.xml</include>
        <include>*.properties</include>
        
        <include>xxx.keystore</include>
    </includes>
</resource>
```

2. assembly.xml中的resource默认配置
> 把需要打包的文件添加到include中

```xml

<fileSet>
    <directory>${basedir}/target/classes</directory>
    <outputDirectory>config</outputDirectory>
    <fileMode>0644</fileMode>
    <includes>
        <include>application.yml</include>
        <include>application-${profileActive}.yml</include>
        <include>mapper/**/*.xml</include>
        <include>static/**</include>
        <include>templates/**</include>
        <include>*.xml</include>
        <include>*.properties</include>
        
        <include>xxx.keystore</include>
    </includes>
</fileSet>
```
