该博客展示了如何使用GET和POST方式调用RESTful接口。对于GET方式，通过HttpURLConnection打开连接，设置请求头并读取响应。而对于POST方式，使用HttpClient创建POST方法，设置请求体和请求头，然后执行并解析响应。

1.get方式

import java.io.IOException;

import java.io.InputStream;

import java.net.HttpURLConnection;

import java.net.MalformedURLException;

import java.net.URL;

import org.apache.commons.io.IOUtils;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import com.alibaba.fastjson.JSONObject;

public class MapService implements IMapService {

//日志记录

private static final Logger LOG = LoggerFactory.getLogger(MapService.class);

//FOSS获取长地址url

private String shortAdrUrl;

public String getShortAdrUrl() {

return shortAdrUrl;

}

public void setShortAdrUrl(String shortAdrUrl) {

this.shortAdrUrl = shortAdrUrl;

}

/**

* @功能：获取短地址对应的长地址

* @时间：2014年11月5日下午8:14:18

* @return：

@Override

public String transAdr(String shortUrl) {

String urlPath = shortAdrUrl + shortUrl;

String longUrl = "";

URL url;

try {

url = new URL(urlPath);

HttpURLConnection httpConn = ((HttpURLConnection) url.openConnection());

httpConn.addRequestProperty("ContenType","application/json;charset=utf-8");

InputStream input = httpConn.getInputStream();

String jsonString = IOUtils.toString(input);

JSONObject jsonObj = JSONObject.parseObject(jsonString);

//获取的状态，成功为true,失败为false

JSONObject jsonObj2 = jsonObj.getJSONObject("OrgGisUrlInfoDto");

boolean state = jsonObj2.getBoolean("state");

//成功获取长地址

if(state) {

longUrl = jsonObj2.get("depCoodinate").toString();

LOG.info("短地址信息为：" + shortUrl + "，对应的长地址信息为：" + longUrl);

}

} catch (MalformedURLException e) {

e.printStackTrace();

LOG.error(e.getMessage());

} catch (IOException e) {

e.printStackTrace();

LOG.error(e.getMessage());

}

return longUrl;

}

2、post方式

import java.io.IOException;
import java.util.Map;

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.methods.PostMethod;
import org.apache.commons.httpclient.methods.RequestEntity;
import org.apache.commons.httpclient.methods.StringRequestEntity;
import org.codehaus.jackson.map.ObjectMapper;

import com.alibaba.fastjson.JSONObject;

public class TestFossUrl {

/**
* MAP类型数组转换成NameValuePair类型
*
* @param properties
* MAP类型数组
* @return NameValuePair类型数组
* http://192.168.17.141:8680/esb2/rs/ESB_CRM2ESB_ORDER_STATE"
* http://10.224.65.123:8089/webWsPro/webservice/ows/app/changed;
*/
private static final String URI = " http://10.224.70.124:8080/bse-baseinfo-web/services/gisUrl/queryLongUrlByShortUrl";

public static void main(String[] args) throws IOException {
HttpClient httpClient = new HttpClient();
// 设置编码格式
httpClient.getParams().setContentCharset("UTF-8");
// 构造PostMethod的实例
PostMethod postMethod = new PostMethod(URI);
try {
JSONObject jsonObj = new JSONObject();
jsonObj.put("shortUrl", "llllll");

String js = jsonObj.toString();
RequestEntity entity = new StringRequestEntity(js,
"application/json", "UTF-8");
postMethod.setRequestEntity(entity);
postMethod.addRequestHeader("Content-Type",
"application/json;charset=UTF-8");
// 执行postMethod
int statusCode = httpClient.executeMethod(postMethod);
if (statusCode != 200) {
// LOGGER.info("ESBADDRESS_REQUEST_ERROR_URL_CANNOTFOUND"+propertyFactory.getEsbRsUrl());
}
String responseBody = postMethod.getResponseBodyAsString();
Map<String, Object> returnMap = new ObjectMapper().readValue(
responseBody, Map.class);
System.out.println(responseBody);

} catch (Exception e) {
e.printStackTrace();
} finally {
postMethod.releaseConnection();
}

}
