http发送post xml请求参数据

1、pom引入jar

        <dependency>
            <groupId>com.fasterxml.jackson.dataformat</groupId>
            <artifactId>jackson-dataformat-xml</artifactId>
            <version>2.9.0</version>
        </dependency>
        <dependency>
            <groupId>commons-httpclient</groupId>
            <artifactId>commons-httpclient</artifactId>
            <version>3.1</version>
        </dependency>

2、配置xml实体类

import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlProperty;
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlRootElement;
import lombok.Data;

@Data
@JacksonXmlRootElement(localName = "DocumentElement")
public class DocumentElementBean {
    @JacksonXmlProperty(localName = "Name")
    private String name;
    @JacksonXmlProperty(localName = "Phone")
    private String phone;
    @JacksonXmlProperty(localName = "DataTable")
    private DataTableBean dt;

}

import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlProperty;
import com.fasterxml.jackson.dataformat.xml.annotation.JacksonXmlRootElement;
import lombok.Data;

@Data
@JacksonXmlRootElement(localName = "DataTable")
public class DataTableBean {
    @JacksonXmlProperty(localName = "Text")
    private String text;
}

3、httpclient 发送post请求

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpStatus;
import org.apache.commons.httpclient.methods.PostMethod;

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;

public class HttpUtil {
    /**
     * 发送xml请求到server端
     * @param url xml请求数据地址
     * @param xmlString 发送的xml数据流
     * @return null发送失败，否则返回响应内容
     */
    public static String sendPost(String url,String xmlString){
        //创建httpclient工具对象
        HttpClient client = new HttpClient();
        //创建post请求方法
        PostMethod myPost = new PostMethod(url);
        //设置请求超时时间
        client.setConnectionTimeout(3000*1000);
        String responseString = null;
        try{
            //设置请求头部类型
            myPost.setRequestHeader("Content-Type","text/xml");
            myPost.setRequestHeader("charset","utf-8");
            //设置请求体，即xml文本内容，一种是直接获取xml内容字符串，一种是读取xml文件以流的形式
            myPost.setRequestBody(xmlString);
            int statusCode = client.executeMethod(myPost);
            //只有请求成功200了，才做处理
            if(statusCode == HttpStatus.SC_OK){
                InputStream inputStream = myPost.getResponseBodyAsStream();
                BufferedReader br = new BufferedReader(new InputStreamReader(inputStream,"utf-8"));
                StringBuffer stringBuffer = new StringBuffer();
                String str = "";
                while ((str = br.readLine()) != null) {
                    stringBuffer.append(str);
                }
                responseString = stringBuffer.toString();
            }
        }catch (Exception e) {
            e.printStackTrace();
        }finally{
            myPost.releaseConnection();
        }
        return responseString;
    }

}

4、main方法测试 

public static void main(String[] args) {
        ObjectMapper mapper = new XmlMapper();
        DocumentElementBean bean = new DocumentElementBean();
        bean.setName("ceshi");
        bean.setPhone("13511112222");
        DataTableBean dataTable = new DataTableBean();
        dataTable.setText("子测试");
        bean.setDt(dataTable);
        String xmlString = "<?xml version=\"1.0\" encoding=\"utf-8\"?>" + mapper.writeValueAsString(bean);
        System.out.println("请求参数=" + xmlString);
        String responseString = HttpUtil.sendPost(url, xmlString);
        System.out.println("返回参数=" + responseString);
    }
