2.12.2. camel:validate

对于以下 Camel 功能的源代码验证：

  • 端点 URI
  • 简单表达式或 predicates
  • 重复路由 ID

然后，您可以从命令行运行 camel:validate 目标，或者从 Java 编辑器（如 IDEA 或 Eclipse）中运行。 

mvn camel:validate

您还可以启用插件以在构建过程中自动运行，以捕获这些错误。 

<plugin>
  <groupId>org.jboss.redhat-fuse</groupId>
  <artifactId>camel-maven-plugin</artifactId>
  <executions>
    <execution>
      <phase>process-classes</phase>
      <goals>
        <goal>validate</goal>
      </goals>
    </execution>
  </executions>
</plugin>

该阶段决定插件何时运行。在以上阶段的示例中，进程类 是在主源代码编译后运行的。maven 插件也可以配置为验证测试源代码，这意味着应相应地将阶段改为 process-test-classes，如下所示： 

<plugin>
  <groupId>org.jboss.redhat-fuse</groupId>
  <artifactId>camel-maven-plugin</artifactId>
  <executions>
    <execution>
      <configuration>
        <includeTest>true</includeTest>
      </configuration>
      <phase>process-test-classes</phase>
      <goals>
        <goal>validate</goal>
      </goals>
    </execution>
  </executions>
</plugin>

2.12.2.1. 在任何 Maven 项目上运行目标

您还可以在任何 Maven 项目上运行验证目标，而无需将插件添加到 pom.xml 文件中。这样做需要通过其完全限定名称指定插件。例如，若要在 Apache Camel 的 camel-example-cdi 上运行目标，您可以运行 

$cd camel-example-cdi
$mvn org.apache.camel:camel-maven-plugin:2.20.0:validate

然后，运行并输出以下内容： 

[INFO] ------------------------------------------------------------------------
[INFO] Building Camel :: Example :: CDI 2.20.0
[INFO] ------------------------------------------------------------------------
[INFO]
[INFO] --- camel-maven-plugin:2.20.0:validate (default-cli) @ camel-example-cdi ---
[INFO] Endpoint validation success: (4 = passed, 0 = invalid, 0 = incapable, 0 = unknown components)
[INFO] Simple validation success: (0 = passed, 0 = invalid)
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------

验证通过的验证，4 个端点已被验证。现在假定我们在源代码中的一个 Camel 端点 URI 中出现了拼写错误，例如： 

@Uri("timer:foo?period=5000")

被修改为在 period 选项中包含拼写错误 

@Uri("timer:foo?perid=5000")

在运行验证目标时，再次报告以下内容： 

[INFO] ------------------------------------------------------------------------
[INFO] Building Camel :: Example :: CDI 2.20.0
[INFO] ------------------------------------------------------------------------
[INFO]
[INFO] --- camel-maven-plugin:2.20.0:validate (default-cli) @ camel-example-cdi ---
[WARNING] Endpoint validation error at: org.apache.camel.example.cdi.MyRoutes(MyRoutes.java:32)

	timer:foo?perid=5000

	                   perid    Unknown option. Did you mean: [period]


[WARNING] Endpoint validation error: (3 = passed, 1 = invalid, 0 = incapable, 0 = unknown components)
[INFO] Simple validation success: (0 = passed, 0 = invalid)
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
