Spring 启动集成测试 - Maven 测试缺少 JSTL

Question

我正在尝试使用 Selenium 为我们的应用程序实施集成测试。我们的想法是加载我们 SpringMVC 项目的 applicationcontext，启动一个嵌入式 Tomcat 容器，然后对其进行运行集成测试，然后关闭并完成应用程序编译。

现在运行从 Eclipse 中进行 JUnit 测试以 Spring 完美启动服务器，但是当运行ning Maven 测试和访问网站时（通过或不通过 Selenium） )，我得到以下异常：

org.apache.jasper.JasperException: The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application

但是，JSTL 在 Maven 中范围 test 的类路径中。有谁知道，为什么会这样？

我的配置分为一个父项目，一个用于我们项目的内部库，另一个用于实际项目。我省略了 pom.xml:

像这样尝试 deps :

<groupId>javax</groupId>
        <artifactId>javaee-api</artifactId>
        <version>6.0</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
        <version>2.5</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>jstl</artifactId>
        <version>1.2</version>
    </dependency>

Answer 2

事实证明，默认情况下，Maven 的 Surefire 插件采用了一种技巧，它创建了一个 Manifest-Only JAR 文件，以避免需要将完整的类路径传递给分叉的 JRE（请参阅本文）。 Jetty JSP 处理器只是向每个类加载器询问其 URL 列表，因此只能看到一个仅包含清单的 JAR 文件，而不是实际使用的所有 JAR 文件，因此找不到 TLD文件。

该页面上也有记录的简单解决方案是关闭 useManifestOnlyJar 选项，如下所示：

<plugins>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.18.1</version>
    <configuration>
      <useManifestOnlyJar>false</useManifestOnlyJar>
    </configuration>
  </plugin>
  ....
<plugin>

这指示 Surefire 将完整的类路径直接传递给分叉的 JRE 进程，从而允许它定位 TLD。已回答 from here.
