配置 Jetty 9 的 Context Path

在 Jetty 9 中配置contextPath可以通过多种方式实现，以下是几种常见的方法：

通过web.xml配置

在web.xml文件中，可以通过<context-param>设置contextPath。例如：

<context-param> <param-name>contextPath</param-name> <param-value>/yourContextPath</param-value> </context-param>

这种方式适用于传统的 WAR 部署方式。

通过 Jetty 的context.xml配置

在 Jetty 的context.xml文件中，可以直接指定contextPath。例如：

<Configure class="org.eclipse.jetty.webapp.WebAppContext"> <Set name="contextPath">/yourContextPath</Set> </Configure>

这种方式适用于独立部署的 Jetty 服务器。

通过编程方式配置

在代码中，可以通过WebAppContext类直接设置contextPath。例如：

WebAppContext webapp = new WebAppContext(); webapp.setContextPath("/yourContextPath");

这种方式适用于嵌入式 Jetty 服务器。

通过 Jetty 的启动参数配置

在启动 Jetty 时，可以通过命令行参数指定contextPath。例如：

java -jar jetty-runner.jar --path /yourContextPath yourApp.war

这种方式适用于使用jetty-runner快速部署应用。

通过 Maven 插件配置

如果使用jetty-maven-plugin，可以在pom.xml中配置contextPath。例如：

<plugin> <groupId>org.eclipse.jetty</groupId> <artifactId>jetty-maven-plugin</artifactId> <version>9.4.0.v20161208</version> <configuration> <webApp> <contextPath>/yourContextPath</contextPath> </webApp> </configuration> </plugin>

这种方式适用于开发阶段的快速测试。

注意事项

• 确保contextPath以/开头，但不以/结尾。
• 如果配置多个contextPath，可能会导致冲突或不可预期的行为。
• 在嵌入式 Jetty 中，contextPath的设置优先级高于web.xml中的配置。
