nacos与assembly

一、使用nacos管理配置文件

1、在pom.xml中添加nacos的依赖

    com.alibaba.cloud
    spring-cloud-starter-alibaba-nacos-config

2、删除管理配置信息的application.yam文件，添加nacos的配置文件bootstrap.yml

nacos:
  server-addr: 121.56.163.65:8858
  username: nacos-dev
  password: zhy@whld@dev
spring:
  profiles:
    active: dev
  cloud:
    nacos:
      config:
        server-addr: ${nacos.server-addr}
        username: ${nacos.username}
        password: ${nacos.password}
        namespace: tsp-${spring.profiles.active}
        prefix: location-service
        file-extension: yaml
        shared-configs:
          - data-id: common.yaml
          - data-id: logger.yaml
      discovery:
        username: ${nacos.username}
        password: ${nacos.password}
        metadata:
          app-version: "@project.version@"
          build-time: "@timestamp@"
          lincontrol-boot-version: "@lincontrol.boot.version@"

3、在nacos中添加配置信息

 二、使用maven插件assembly实现打包

1、pom.xml中添加打包的配置

        ${basedir}
        true
        8
        8
        ${maven.build.timestamp}
        
        yyyy-MM-dd HH:mm:ss
        ${parent.version}
    

    
        lincontrol-location-service
        
            
                org.springframework.boot
                spring-boot-maven-plugin
                
                    true
                
                
                    
                        
                            repackage
                        
                    
                
            

            
                org.apache.maven.plugins
                maven-jar-plugin
                
                    
                        
                            true
                            
                            com.dsh.VehicleServiceApplication
                        
                    
                
            
            
                maven-assembly-plugin
                
                    
                        ${main.basedir}/assembly/assembly.xml
                    
                
                
                    
                        package 
                        
                            single
                        
                    
                
            
        
        
            
                src/main/resources
                true
            
        
    

 2、添加assembly.xml文件

 

    ${project.version}
    
        tar.gz
    
    lincontrol
    
        
            ${project.build.directory}/lincontrol-location-service.jar
            location-service.jar
        
        
            ${main.basedir}/bin/jvm.options
            bin
            jvm-location-service.options
        
        
            ${main.basedir}/bin/server.bat
            bin
            0755
            server-location-service.bat
        
        
            ${main.basedir}/bin/server.sh
            bin
            
            0755
            server-location-service.sh
        
    

3、添加jvm.options文件设置编码、限制内存

-Duser.timezone=GMT+8
-Xms256m
-Xmx521m

 4、添加server.bat文件，编写打包的启动停止脚本

 

@echo off
chcp 65001
rem 启动扩展本地环境变量延迟
setlocal enabledelayedexpansion

rem 通过文件名截取出服务名称
set filename=%~n0
set service_name=%filename:server-=%

rem 默认参数
set jvm_options_file=%~dp0jvm-%service_name%.options
set spring_profiles_active=prod

rem 读取参数
:readParams
set p=%*
:loop
for /f "tokens=1*" %%a in ("%p%") do (
	set p=%%b
	for /f "tokens=1* delims==" %%i in ("%%a") do (
		if "%%i"=="jvm" (
			if not "%%j"=="" set jvm_options_file=%cd%\%%j
		) else if "%%i"=="active" (
			if not "%%j"=="" set spring_profiles_active=%%j
		) else (
			echo unknown parameter name: %%i
			goto usage
		)
	)
)
if defined p goto loop
goto start

:usage
echo Usage: %0 [jvm=^] [active=^]
echo   jvm:        可选。jvm配置文件,默认值 %~dp0jvm-%service_name%.options
echo   active:     可选。jar包启动的配置,默认值prod,即配置文件为application-prod.yml
echo Example: '%0' or '%0 active=prod'
goto :eof

:start
echo service name is %service_name%
title %service_name%
if not exist %jvm_options_file% (
  echo Error: Unable to access jvm options file %jvm_options_file%
  goto :eof
)
rem 输出配置文件目录
echo jvm-options-file:%jvm_options_file%

rem 读取文件第一列,type是显示文件内容的命令
set jvm_options=-Dfile.encoding=utf-8
for /f %%a in ('type %jvm_options_file%') do (
  rem 必须用!!而不能用%%
  set jvm_options=!jvm_options! %%a
)
rem 输出jvm配置
echo jvm-options:%jvm_options%
rem 输出启动环境
echo spring.profiles.active=%spring_profiles_active%


rem jar包路径
set jar_path=%~dp0..\%service_name%.jar
if not exist %jar_path% (
  echo Error: Unable to access jarfile %jar_path%
  goto :eof
)
rem 启动
java %jvm_options% -jar %jar_path% --spring.profiles.active=%spring_profiles_active%
endlocal

 5、添加server.sh文件，编写打包的启动停止脚本

#!/usr/bin/env bash

BIN="${BASH_SOURCE-$0}"
DIR_NAME="$(dirname ${BIN})"
# 脚本所在路径
DIR="$(cd ${DIR_NAME}; pwd)"
# 程序根目录
PROGRAM_ROOT=${DIR%/*}

# 通过文件名截取出服务名称
filename=${0##*/server-}
service_name=${filename%.sh}
# 默认参数
jvm_options_file=${DIR_NAME}/jvm-${service_name}.options
spring_profiles_active=prod
# 其它参数
other_params=
# 运行名称,用来记录pid的唯一标识
pid_name=

# 打印错误信息
error(){
  echo -e "\033[31m$1\033[0m"
}

info(){
  echo -e "\033[34m$1\033[0m"
}

showUsage(){
  echo "Usage: $0 {start|stop|restart|status} [jvm=] [active=]"
  echo "  start|stop|restart|status:     必选。启动|停止|重启|状态"
  echo "  jvm:                           可选。jvm配置文件,默认值 ${DIR_NAME}/jvm-${service_name}.options"
  echo "  active:                        可选。jar包启动的配置,默认值prod,即配置文件为application-prod.yml"
  echo "  name:                          可选。启动后用来存储pid的唯一标识符,pid存储文件为[jar包所在目录]/pid/server-${service_name}-[name].pid"
  echo "Example: '$0 start' or '$0 start active=prod'"
}
