Spring Boot 示例在 Eclipse 中抛出 MojoExecutionException
Posted
技术标签:
【中文标题】Spring Boot 示例在 Eclipse 中抛出 MojoExecutionException【英文标题】：Spring Boot sample throws MojoExecutionException in eclipse 【发布时间】：2016-03-07 11:57:44 【问题描述】：我正在使用this tutorial 研究 Spring 安全性和 AngularJS。本教程的第一部分指定了对pom.xml 的非常具体的更改。但是当我添加那些pom.xml 更改时，会导致错误。
在eclipse中，错误是编译错误信息如下：
Plugin execution not covered by lifecycle configuration: ro.isdc.wro4j:wro4j-maven-plugin:1.7.6:run (execution: default, phase: generate-resources)
出现在pom.xml 中的以下行：
<execution> <!-- this line throws the compilation error in eclipse -->
<phase>generate-resources</phase>
<goals>
<goal>run</goal>
</goals>
</execution>
当我试图通过在 CentOS 终端上运行 mvn spring-boot:run 来绕过 eclipse 时，以下堆栈跟踪结果：
[root@localhost demo]# mvn spring-boot:run

请注意，上面的堆栈跟踪中混有address already in use 错误。一开始我以为这个错误可能是因为重启程序时8080端口冲突，但即使我运行shutdown.sh和startup.sh重启tomcat，问题仍然存在。另外，请注意消息在堆栈跟踪的末尾表明 pom.xml 中的插件可能导致问题，您可以验证by clicking on this link。

我在 Eclipse 中使用 Spring Tool Suite 插件创建了项目，方法是选择 File > New > Project... > Spring > Spring Starter Project 并仅使用默认参数，然后明确按照上述链接教程中的说明进行操作。
教程中的说明一直有效，直到我将更改添加到上面显示的pom.xml 并在教程的第一部分中进行了阐述。
那么我要怎么做才能让程序编译？
【问题讨论】：
不要做shutdown.sh和startup.sh来重启tomcat。只需确保您在 CentOS 中的 Tomcat 已关闭并尝试执行mvn spring-boot:run
@localhost999 我重新启动了机器，现在可以通过在 CentOS 终端输入 mvn spring-boot:run 来运行程序。这使该终端窗口处于半冻结状态，表明它已发出的命令仍在运行。在这种状态下如何终止并重新启动 Spring Boot 应用程序？当我想运行重新编译的程序时，我是否只是 Ctrl-C 然后再次输入 mvn spring-boot:run？这种方法完全绕过了 eclipse。
我知道这已经晚了，但它也可以帮助其他人。尝试运行 mvn clean install spring-boot:run 这将重新编译您的程序并运行您的 Spring Boot 应用程序
【参考方案1】：
当你执行mvn spring-boot:run时，它有自己的嵌入式Tomcat，所以它不需要单独的Tomcat实例来运行，因此这两个Tomcat之间存在冲突。
你只需要运行：shutdown.sh，然后再试一次。
【讨论】：
这并不能解决问题。但是，重新启动计算机确实可以使应用程序再次运行。但是当我第二次尝试重新编译并启动问题时，问题再次出现，并通过重新启动计算机再次解决。 那么您的问题在于 IDE 或运行命令的实用程序，发生的情况是，当您第一次运行应用程序时，它保持打开状态。让我知道您使用的是哪个 IDE，或者如果终端运行ps aux 并搜索 tomcat，例如 ps aux | grep tomcat，如果找到它，您可以使用类似 kill 32423 的进程号将其杀死（例如，32423）
我使用 Eclipse。当我回到我的电脑时，我会尝试 PS aux。这里是半夜。
