如何構建Ribbon程序

本文小編為大家詳細介紹“如何構建Ribbon程序”，內容詳細，步驟清晰，細節處理妥當，希望這篇“如何構建Ribbon程序”文章能幫助大家解決疑惑，下面跟著小編的思路慢慢深入，一起來學習新知識吧。

之前在eclipse中單兒構建第一個Ribbon時，只需要加入以下依賴即可：

	<dependencies>
		<dependency> 
			<groupId>com.netflix.ribbon</groupId>
			<artifactId>ribbon</artifactId>
			<version>2.2.2</version>
		</dependency>
		<dependency>
			<groupId>com.netflix.ribbon</groupId>
			<artifactId>ribbon-httpclient</artifactId>
			<version>2.2.2</version>
		</dependency> 
	</dependencies>

但是以上的依賴，單獨在命令行中使用Maven命令構建，或者在IDEA中構建，則會拋出異常，信息如下：

[ERROR]   符號:   變量 ConfigurationManager
[ERROR]   位置: 類 org.crazyit.cloud.TestPingUrlConfig
[ERROR] /D:/s_book/Spring Cloud/codes/04/4.2/first-ribbon-client/src/main/java/org/crazyit/cloud/TestPingUrlConfig.java:[19,17] 找不到符號
[ERROR]   符號:   變量 ConfigurationManager

[ERROR]   符號:   變量 ConfigurationManager
[ERROR]   位置: 類 org.crazyit.cloud.TestPingUrlConfig
[ERROR] /D:/s_book/Spring Cloud/codes/04/4.2/first-ribbon-client/src/main/java/org/crazyit/cloud/TestRestClient.java:[14,17] 找不到符號
[ERROR]   符號:   變量 ConfigurationManager
[ERROR]   位置: 類 org.crazyit.cloud.TestRestClient
[ERROR] /D:/s_book/Spring Cloud/codes/04/4.2/first-ribbon-client/src/main/java/org/crazyit/cloud/TestRestClient.java:[25,49] 無法訪問com.google.common.reflect.
ypeToken
[ERROR]   找不到com.google.common.reflect.TypeToken的類文件
[ERROR] /D:/s_book/Spring Cloud/codes/04/4.2/first-ribbon-client/src/main/java/org/crazyit/cloud/MyPingTest.java:[15,17] 找不到符號
[ERROR]   符號:   變量 ConfigurationManager

解決方法，使用eclispe或者修改pom.xml，修改后的pom.xml內容如下：

    <dependencies>
        <dependency>
            <groupId>com.netflix.ribbon</groupId>
            <artifactId>ribbon-core</artifactId>
            <version>2.2.2</version>
        </dependency>
        <dependency>
            <groupId>com.netflix.ribbon</groupId>
            <artifactId>ribbon-loadbalancer</artifactId>
            <version>2.2.2</version>
        </dependency>
        <dependency>
            <groupId>com.netflix.archaius</groupId>
            <artifactId>archaius-core</artifactId>
            <version>0.7.5</version>
        </dependency>
        <dependency>
            <groupId>commons-configuration</groupId>
            <artifactId>commons-configuration</artifactId>
            <version>1.9</version>
        </dependency>
        <dependency>
            <groupId>com.netflix.ribbon</groupId>
            <artifactId>ribbon-httpclient</artifactId>
            <version>2.2.2</version>
        </dependency>
        <dependency>
            <groupId>com.google.guava</groupId>
            <artifactId>guava</artifactId>
            <version>18.0</version>
        </dependency>
    </dependencies>

暫時不知道原因，估計是eclipse的Maven插件有問題，自動引入許多依賴。
