HttpClient 3.1版错误

Question

我正在尝试将XML文件作为Http POST请求传递。当我在Linux机器上使用CURL测试它并且XML格式正确时，webservice工作正常。我正在尝试编写一个Java实用程序来执行相同的操作。我在Apache Commons HttpClient库3.1版中找到了一个示例，这是我的代码：

进口：

import java.io.File;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.methods.FileRequestEntity;
import org.apache.commons.httpclient.methods.PostMethod;
import org.apache.commons.httpclient.methods.RequestEntity;

代码：

String strURL = "https://localhost/scoring";
String strXMLFilename = "C:\\Users\\Test.xml";
File input = new File(strXMLFilename);
PostMethod post = new PostMethod(strURL);
RequestEntity entity = new FileRequestEntity(input, "text/xml; charset=ISO--");
post.setRequestEntity(entity);
Get HTTP client
HttpClient httpclient = new HttpClient();
try 
{
   int result = httpclient.executeMethod(post);
   System.out.println("Response status code: " + result);
   System.out.println("Response body: ");
   System.out.println(post.getResponseBodyAsString());
} 
finally 
{
post.releaseConnection();
}

我收到错误：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
at org.apache.commons.httpclient.HttpMethodBase.<clinit>(HttpMethodBase.java:104)
at Test.main(Test.java:40)

更新

添加了Commons-logging-1.2.jar

仍然出错：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/codec/DecoderException
at org.apache.commons.httpclient.HttpMethodBase.<init>(HttpMethodBase.java:220)
at org.apache.commons.httpclient.methods.ExpectContinueMethod.<init>(ExpectContinueMethod.java:93)
at org.apache.commons.httpclient.methods.EntityEnclosingMethod.<init>(EntityEnclosingMethod.java:119)
at org.apache.commons.httpclient.methods.PostMethod.<init>(PostMethod.java:106)
at Test.main(Test.java:40)
Caused by: java.lang.ClassNotFoundException: org.apache.commons.codec.DecoderException

它抛出这一行：

PostMethod post = new PostMethod(strURL);

什么错了？请帮忙。

Answer 1

你错过了类路径中的apache commons-logging.jar。下载并将其添加到类路径中。

更新： 现在您需要commons-codec.jar下载并添加它。

Answer 2

你只需要将Apache Commons Logging jar添加到你的类路径中（如果你使用的是IDE你的项目库）你可以从here下载它。

我已经通过导入以下依赖项解决了这个问题

    <dependency>
        <groupId>commons-httpclient</groupId>
        <artifactId>commons-httpclient</artifactId>
        <version>3.1</version>
        <exclusions>
            <exclusion>
                <groupId>commons-logging</groupId>
                <artifactId>*</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
