tomcat - 从 Maven Tomcat 插件运行 war 文件——插件是否使用了错误的文件？

Question

我正在使用 Vaadin 开发一个 Web 应用程序并对其进行配置，以便它可以在开发、登台和生产环境中运行。我的问题是我无法让 Tomcat7 Maven 插件运行我的 war 文件。战争文件很好——我已经用编辑器检查过它。我在我的 spring-context.xml（我称之为 applicationContext.xml）中使用占位符来代替数据库信息。我使用 Maven 资源过滤来用真实数据替换占位符。这适用于战争文件。

但是，当我尝试使用 Tomcat7 Maven 插件运行时，出现以下错误（我遗漏了清理和测试消息）：

这是我对正在发生的事情的解释。如果我错了，请告诉我。

Vaadin 使用 GWT，因此可以编译。然后war文件被组装和安装。资源被复制和过滤。Maven 检查它是否需要编译，但它不需要。然后 Tomcat 启动并开始自我配置。当它到达 applicationContext.xml 中的数据源时，它会窒息，因为它找到的是占位符而不是真实数据。但为什么？资源已经运行，war 文件和 war 目录有正确的数据。

这是我的 POM 的一部分。我已经改变了很多，但这就是我的目标：

<build>
    <finalName>dpt</finalName>

        <filter>src/main/resources/props/dev.properties</filter>

        <resource>

            <filtering>true</filtering>

Answer 1

事实证明这是 tomcat7-maven-plugin 中的一个错误，或者至少它没有像我预期的那样工作。当它从 Maven 运行 Tomcat 服务器时，它不使用 war 文件或目录中的配置文件。你可以在我做的一个 Github 项目中看到这一点：

编辑：好的，这本身不是一个错误，但 Tomcat 插件和资源过滤插件不会相互通信。没有理由他们应该这样做，除了如果您过滤资源，Tomcat 插件将永远找不到它们。

您必须明确告诉 Tomcat 插件过滤的资源在哪里。默认值为 ${project.build.directory}/${project.build.finalName}，因此您可以将其添加到 Tomcat 插件配置中：

<project>
  ...
  <build>
    ...
    <plugins>
      ...
      <plugin>
        <groupId>org.apache.tomcat.maven</groupId>
        <artifactId>tomcat7-maven-plugin</artifactId>
        <version>${tomcat7MavenPlugin}</version>

        <configuration>
          ...

          <!-- Have Tomcat look in the file filtering folder -->
          <warSourceDirectory>
            ${project.build.directory}/${project.build.finalName}
          </warSourceDirectory>
        </configuration>
        ...
