[英]How to create a war file for my java web application project from terminal without using eclipse
I have a java web application project (maven) that I want to serve on a tomcat server. 我有一个要在雄猫服务器上使用的Java Web应用程序项目(Maven)。 I want to create a .war file from it so then I can place it in the webapps directory.I know that from eclipse I can to do it by the export but I need to do it through terminal.
我想从中创建一个.war文件,然后将其放置在webapps目录中。我知道从eclipse中可以通过导出来完成它,但是我需要通过终端来完成。 also I have tried the
jar cvf example.war *
command but when I put the war file inside the webapps directory tomcat cant read my java application. 我也尝试过
jar cvf example.war *
命令,但是当我将war文件放在webapps目录中时,tomcat无法读取我的Java应用程序。 Can someone please guide me on how to create a war file from terminal that tomcat can read it. 有人可以指导我如何从tomcat可以读取的终端创建war文件。
In pom.xml, add the following line 在pom.xml中,添加以下行
<packaging>war</packaging> // Replace <packaging>jar</packaging> if jar packaging already present
And then go to the parent directory of the project and enter mvn package
. 然后转到项目的父目录并输入
mvn package
。 war file will be generated in war文件将在
/parent_directory/target/myproject.war
If you want to access your project as http://localhost:8080
rather than http://localhost:8080/myproject
, rename myproject.war
to ROOT.war
and paste the war file in webapps of tomcat directory. 如果您要访问您的项目
http://localhost:8080
,而不是http://localhost:8080/myproject
,重命名myproject.war
到ROOT.war
并粘贴到tomcat目录中的webapps战争文件。
Navigate to an appropriate directory(let's say desktop) and use maven-archetype-webapp
to start a simple webapp maven project. 导航到适当的目录(假设为桌面),然后使用
maven-archetype-webapp
启动一个简单的webapp maven项目。 For example: 例如:
mvn archetype:generate -DgroupId=com.mywebapp.www -DartifactId=MyWebApp -DarchetypeArtifactId=maven-archetype-webapp mvn原型:generate -DgroupId = com.mywebapp.www -DartifactId = MyWebApp -DarchetypeArtifactId = maven-archetype-webapp
See: Introduction to Maven Archetypes 请参阅: Maven原型简介
Once your project is created, navigate to the directory which has the pom.xml
and use: 创建项目后,导航至包含
pom.xml
的目录并使用:
mvn package mvn包
Once you are done with step 2, navigate to the target
directory where you would find a MyWebApp.war
generated. 完成第2步后,导航到
target
目录,您将在其中找到生成的MyWebApp.war
。
Copy-paste MyWebApp.war
to tomcat webapps
directory and start the tomcat server( ./startup.sh
). 将
MyWebApp.war
复制并粘贴到tomcat webapps
目录,然后启动tomcat服务器( ./startup.sh
)。
As you can see, we can now access the URL http://localhost:8080/MyWebApp/
. 如您所见,我们现在可以访问URL
http://localhost:8080/MyWebApp/
。
