, args);
在项目根目录下,在控制台执行如下命令:
mvn clean package -Dmaven.test.skip=true
1)mvn clean package其实是两条命令,mvn clean用于清除项目target目录下的文件,mvn package是打包命令。两个命令可以一起执行。
2)-Dmaven.test.skip=true:排除测试代码后进行打包。
将打包好的WAR包复制到Tomcat服务器中的webapps目录下启动即可。

在启动tomcat时报上面错误,无法启动,则考虑是tomcat版本问题,尝试用绿色版的tomcat 8.0 + 进行启动得于解决;
二、Tomcat启动war包
1.打包位置:启动后生成的war包(target包下),复制到tomcat目录下,记得设置tomcat的访问端口号。
2.机器下载的tomcat 8.5xx 压缩包,解压安装。
(1) 编辑 tomcat 配置文件设置 访问端口为 项目配置文件中配置的端口号(保持访问端口不变)
(2) 将打包好的 war 包复制到 tomcat/webapps 目录下
(3) 启动 tomcat:bin/startup.xx
(4) 启动成功,访问接口–>> 404
可能存在的问题: 项目在intellij idea里配置tomcat可以启动访问, 打成war包丢到tomcat webapps下能启动却访问不了相关的接口, 这个问题是因为idea会默认将项目以ROOT为目录的文件,而丢到tomcat的webapps下面则是解压成你项目名称为目录的文件,和ROOT是同级的
可以有以下几种解决方案
一:将war包放在Tomcat的ROOT包下(或者将你的war名称改成作为ROOT.war)
二:在tomcat的server.xml文件的Host标签内配置
<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="false">
<Context Path="" docBase="/ROOT/" debug="0" reloadable="true" />
//<Context path="/" docBase="你项目的地址" reloadable="true"/>
<Context path="/car" docBase="C:\Users\Admin\Desktop\apache-tomcat-8.5.54\webapps\ROOT\JavaWebTest.war" reloadable="true"></Context>
三、设置Tomcat默认访问路径
tomcat默认访问路径为 http://localhost:8080/项目名/页面等路径,有些客户要求只输入IP,自动进入项目登录页面,设置如下:
修改tomcat/conf/server.xml
在标签中加入:
<Context path="" docBase="E:\tomcat\webapps\项目文件夹名称" debug="0" reloadable="true" />
path:war包解压后的项目名称,也就是访问路径(例:http://localhost:8080/car/)
docBase:war包的路径(需要把war包的后缀名加上,如上图所示,避免报错)
reloadable:自动加载
保存上述修改后,双击\bin\startup.bat启动Tomcat即可
三:前端访问不到后端接口问题
用tomcat发布时,将前端请求的路径加上你的项目名称
正常启动后,地址栏输入localhost:8080会进入tomcat路径,ROOTweb.xml指定的index页面。
所以要在地址栏输入localhost:8080/war包名称/ 就会进入tomcat路径中自己的文件夹。(该文件夹就是自己war被解析后生成的)
2.启动中文乱码问题:
启动Tomcat后,产生的日志有乱码的情况出现,不要慌,这并不影响你项目的正常运行。这是由于编码不一致引起的,Tomcat启动后默认编码UTF-8,而Windows的默认编码是GBK。因此你想让其不乱码,只需配置conf\logging.properties的编码格式即可
