打包命令

前台js打包 需要:node.js

1
npm run build

普通WEB项目 需要:ant

1
2
ant -buildfile build.xml
#进入项目目录,在有build.xml的目录,使用命令打包

maven项目 需要:maven

1
2
maven clean install -P{profile} -Dmaven.test.skip=true
#clean清理本地库 install编译打包可执行的war -P指定多环境参数 -Dmaven.test.skip=true 跳过测试

java -jar nmk.jar --spring.profiles.active=dev
#可在java后配置启动参数 -Xms512m -Xmx1024m 限制项目使用内存
#--spring.profiles.active 指定多环境
#在linux启动请在启动命令最后加& 代表后台运行,如果项目在你断掉连接时挂掉请使用nohup+&
#示例如下:
#nohup java -Xms512m -Xmx1024m -jar nmk.jar --spring.profiles.active=prod >> catalina.out 2>&1 &
#指定程序后台启动,使用prod环境配置运行,最大堆内存为1024M,启动日志输出到catalina.out

tomcat项目

  • windows下

    把war包或文件夹放入tomcat/webapps下,启动tomcat/bin目录下的startup.bat
    可在catalina.bat开头配置堆内存
    set JAVA_OPTS=-server -Xms512m -Xmx1024m

  • linux下

    把war包或文件夹放入tomcat/webapps下,进入tomcat/bin目录下
    chmod +x startup.sh #授权执行权限
    chmod +x catalina.sh 
    ./startup.sh 或sh startup.sh启动tomcat
    可在catalina.sh开头配置堆内存
    JAVA_OPTS="-Xms512m -Xmx1024m"

*项目环境必须有安装JDK

bug:

项目中图片中文名称,访问页面不显示问题

修改tomcat的conf/server.xml,增加编码格式

修改前<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="18883" URIEncoding="UTF-8"/>
修改后<Connector port="8080" protocol="HTTP/1.1" URIEncoding="UTF-8"
               connectionTimeout="20000"
               redirectPort="443"/>

重启tomcat即可解决

maven将jar包添加到本地仓库

情景描述：当项目所需的jar包，maven中央仓库中没有该jar包时，如何将jar包添加到本地仓库呢？

错误做法：直接将jar包拷贝到本地仓库目录下

正确做法：　　1.首先，搭建maven运行环境；　　2. 使用maven命令，将jar包添加到本地仓库；

maven安装jar包的命令是：

1
mvn install:install-file -Dfile=jar包的位置 -DgroupId=设置groupId -DartifactId=设置artifactId -Dversion=设置version -Dpackaging=jar

前端打包失败

在windows打包成功,在jenkins中打包失败,查看npm和node发现版本不一致
查看其版本

更新npm ：
npm install -g npm
更新指定版本 ：
npm install -g npm@6.9.0
更新node版本：
首先安装n模块
npm install -g n
安装好n模块后可以选择下面其一升级：

选择一：升级node.js到最新稳定版
n stable

选择二：升级node.js到最新版
n latest

选择三：升级node.js到指定版本
n v14.16.0
如果出现没有n命令提示,请进入node安装目录的bin下进行执行

还是出现报错

注意大小写,
windows对大小写不敏感,大小写都是对的,
linux对大小写很敏感,不对就会报错

修改项目中的大小写,再次编译打包成功
