java - 使用 Camel 调用 REST URL

Question

我需要从 Camel 调用本地的休息服务。

当我从浏览器调用 URL 时，我得到了响应。

例如

http://localhost:8081/buzzor/secure/buzzorapp/getAvailableLanguages

我得到了结果:

 [
    {
        "name": "English",
        "value": "en"
    },
    {
        "name": "मराठी",
        "value": "mr"
    },
    {
        "name": "ગુજરાતી",
        "value": "gu"
    },
    {
        "name": "தமிழ்",
        "value": "ta"
    },
    {
        "name": "हिन्दी",
        "value": "hi"
    },
    {
        "name": "Français",
        "value": "fr"
    },
    {
        "name": "తెలుగు",
        "value": "te"
    }
]

现在我需要从 Camel 调用相同的 REST URL，为此我创建了一条路由。

<camelContext xmlns="http://camel.apache.org/schema/spring" trace="false">
    <route>
        <from uri="direct:start" />
        <to uri="http://localhost:8081/buzzor/secure/buzzorapp/getAvailableLanguages" />
    </route>
</camelContext>

执行此操作后，如果我运行项目 URL 则不会被调用。请告诉我我在哪个地方犯了错误。在控制台站点上我只得到输出:

[INFO] Nothing to compile - all classes are up to date
[INFO] 
[INFO] <<< camel-maven-plugin:2.15.1:run (default-cli) < test-compile @ CXF-Sample <<<

看起来您正在使用direct端点作为消费者。这意味着您需要将交换发送到 direct:start 才能触发 http get。

使用运行一次的计时器怎么样？

<camelContext xmlns="http://camel.apache.org/schema/spring" trace="false">
  <route>
    <from uri="timer:foo?repeatCount=1" />
    <to uri="http://localhost:8081/buzzor/secure/buzzorapp/getAvailableLanguages" />
  </route>
</camelContext>

此路由将运行并调用 http 端点一次。
