spring - 无法在测试类中导入 applicationContext

Question

我的applicationContext.xml,webmvc-config.xml在WEB-INF/spring/applicationContext.xml

当我尝试以下操作时，它没有加载，我得到 java.io.FileNotFoundException

@ContextConfiguration(locations = { "classpath:WEB-INF/spring/applicationContext.xml" })

我正在使用 spring 3，junit 4.7。

它通过复制 resources 文件夹中的 applicationContext.xml 来处理肮脏的解决方法，因此它是重复的。

我将加载更改为:

@ContextConfiguration(locations = { "classpath:/applicationContext.xml" })

我的 web.xml:

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">

请提出更好的解决方案。

Answer 1

Web 应用程序的类路径由

• WEB-INF/类
• WEB-INF/lib下的所有jar包

所以，如果你想从类路径加载上下文文件，你需要在这些地方之一。把它放在 WEB-INF/classes/spring 中，然后使用 classpath:spring/applicationContext.xml 加载它。

编辑:我刚刚意识到您在从 JUnit 测试加载上下文文件时遇到问题。不过答案是相似的。包含 WEB-INF 的目录肯定不在单元测试运行器的类路径中。单元测试运行器应该使用与应用程序服务器大致相同的类路径，因此文件应该位于一个位置，使其在构建后进入 JAR 文件或测试类路径中的目录。如果使用 Maven，src/main/resources 目录通常是其中之一:该目录中的所有内容都转到 target/classes 目录，该目录位于单元测试运行器。
