问题描述

我有一个 Java Project ,我正在创建一个Web界面,使用动态Web项目从Eclipse。 Web项目由单个 servlet 和两个 JSP 组成。这样的东西:

I have a Java Project, for which I'm now creating a Web interface, using a Dynamic Web Project from Eclipse. The Web project consists of a single servlet and two JSP's. Something like this:

/JavaApplication
  /src
  /lib
  /resources
/WebApplication
  /src
    /Servlet.java
  /WebContent
    /WEB-INF
    index.jsp
    other.jsp

现在,我需要从<$ c $中引用 JavaApplication c> WebApplication ,以便使用其类来处理Web请求。什么是最好的方式来完成这个?我的想法是创建一个 .jar JavaApplication ,其中包含所有的 .class 文件, / resources / libs 。这样,我可以在Web应用程序中包含.jar,我可以有一个包含整个应用程序的单个 .war 文件。

Now, I need to reference JavaApplication from WebApplication, in order to use its classes to process web requests. What's the best way to accomplish this ? My idea is to create a .jar of the JavaApplication, containing all the .class files, /resources, and /libs. In this way, I could include the .jar in the web application, and I could have a single .war file that contained the entire application.

你觉得怎么样?这个问题通常解决了吗?

What do you think? How is this problem typically solved ?

注意:我不想将Java项目转换为Web项目。

Note: I don't want to convert the Java Project into a Web project.

推荐答案

在Eclipse下,您可以为您的案例中的Web应用程序为给定的项目声明项目引用。为此,请右键单击您的Web应用程序项目,然后转到属性>项目引用,然后选择 JavaApplication 项目。这应该允许您从 WebApplication 中的 JavaApplication 项目中调用代码,而无需构建WAR。这是开发的解决方案。

Under Eclipse, you can declare Project References for a given project, the web application in your case. To do so, right click on your web application project, then go for Properties > Project References and select the JavaApplication project. This should allow you to call code from the JavaApplication project from the WebApplication without having to build a WAR. This is a solution for development.

对于标准的部署(IDE外),您应该创建一个标准战争为此,您必须将您的 JavaApplication 打包为JAR,其中包括 .class 文件和 / resources 依赖的库(JARs在 / lib 下)。这些依赖关系实际上最终会在WAR的 WEB-INF / lib 目录中,而您的 JavaApplication 。这些步骤通常是自动化的,其中包括 Ant Maven

For standard deployment (outside the IDE), you should indeed create a standard WAR. To do so, you'll have to package your JavaApplication as a JAR including the .class files and the files under /resources but not the libraries it depends on (JARs under /lib). These dependencies will actually end up in the WEB-INF/lib directory of the WAR, beside the JAR of your JavaApplication. These steps are typically automated with tools like Ant or Maven.
