Eclipse将.war文件放在哪里？

Question

Eclipse将.war文件放在哪里？

5

我是Java EE网络开发的新手。我在Eclipse中创建了一个基于JAX-RS的Web应用程序，并在Tomcat上运行。该项目由Maven管理依赖项。一切都正常工作。但是，现在如果我要发布这个项目，我会假设我需要向用户提供一个.war文件。

那么这就是我的问题：

1. Eclipse将war文件放在哪里？ 2. 这个文件是否包含了所有正确顺序运行为Web应用程序所需的内容，还是我需要额外提供其他文件，例如web.xml或pom.xml？ 3. 如果应用程序的用户已经下载了Tomcat，他/她只需要将.war文件复制到Tomcat目录中并右键单击运行吗？

在项目中右键单击 > 导出 > web 项目 > .war，然后将 .war 文件复制到您的 Apache Tomcat 的 webapp 目录中。

如果您使用Maven并已正确配置，则创建war文件的最简单方法是调用以下命令： $ mvn clean install

在项目目录中（即pom.xml所在位置），之后您将在以下位置找到生成的war文件： path_to_your_project/targe/your_application.war

Even I am new to J2EE Web Application development.
I am using Tomcat 8.0.27 and Eclipse Luna.
From my trial and error, I have noticed that after successful Maven Build creation (pom.XML --> Run As (4 Maven Clean OR 6 Maven Install); the war file is saved in the user folder as below.

C:\Users\username\\.m2\repository\com\i4\I4Connect\0.0.1-SNAPSHOT\I4Connect-0.0.1-SNAPSHOT.war

In the fore mentioned folder 
(C:\Users\username\\.m2\repository\com\i4\I4Connect\0.0.1-SNAPSHOT\); I also see the following files along with the mentioned war file.
1. _remote.repositories --> Repositories file
2. I4Connect-0.0.1-SNAPSHOT.pom --> POM file
3. maven-metadata-local --> XML file

Hope this helps.

Hello Again,

what i realized was, the war file created earlier was a snapshot.
However, when I closely tracked the build creation again, I noticed that eclipse provides details of every step of the build creation that could be observed in the console.
Following is snapshot of what I got when I re-created the build.

Eclipse本身不会将任何东西放在任何地方。当您使用Maven构建项目时，根据Maven文件夹结构，它将在目标目录中构建并放置WAR文件，该目录位于文件系统中的项目所在位置（通常在您的工作区内），您可以在Eclipse包/项目资源管理器中看到。

尝试使用mvn clean package构建您的项目

如果您的POM.xml中所有依赖项的范围都为“compile”，那么Maven将把这些相应的JAR推送到web-inf / lib中，但是如果您有“provided”范围，则必须自己将这些JAR放入服务器中。

Eclipse将WAR文件部署到Tomcat中，具体位置取决于您的Tomcat设置。详情请参见此处。您提到了一个pom.xml文件，所以您可能使用了一些maven插件（比如这里），用于构建war文件。请参考插件文档了解如何配置war文件的创建。
一切都在项目内（在您的情况下，项目已经正确地在maven中进行了配置）。您只需将其部署到服务器即可。
您不应该右键单击或其他操作。只需将其放置到Tomcat安装的webapps文件夹中或通过管理器应用程序进行部署。我想您应该在这里阅读文档，了解什么是部署以及如何进行部署。
