最近项目代码中太多重复的编写Document,不同的接口需要不同的模板,于是重写提取公共部分打成jar包,方便各个系统统一使用~
提取结构:
Http连接方式:
import java.nio.charset.Charset;
import java.util.Arrays;
import java.util.List;
import java.util.Map; import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.MediaType;
import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;
import org.springframework.http.converter.StringHttpMessageConverter;
import org.springframework.web.client.RestTemplate; public class HttpConnect { final Logger logger = LoggerFactory.getLogger(this.getClass()); public static final String SECCUESS_CODE = "000000"; private RestTemplate restTemplate ; private int connectTimeout = 1000; private int readTimeout = 15000; private static final String CHARSET_GBK = "GBK"; public String getMessages(Map<String,Object> sendData){
restTemplate = createRestTemplate();
HttpHeaders headers = new HttpHeaders();
MediaType type = new MediaType("text", "xml",
Charset.forName(CHARSET_GBK));
headers.setContentType(type);
String connectIp = (String) sendData.get("RequestIp");
String connectPort = (String) sendData.get("RequestPort");
String content = (String) sendData.get("message");
String url = "http://" + connectIp + ":" + connectPort;
HttpEntity<String> entity = new HttpEntity<String>(content, headers);
String result = restTemplate.postForObject(url, entity, String.class);
logger.info("send data:{},result:{}", content, result); return result;
} public RestTemplate createRestTemplate() {
HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
requestFactory.setConnectTimeout(connectTimeout);
requestFactory.setReadTimeout(readTimeout); RestTemplate restTemplate = new RestTemplate(requestFactory);
restTemplate.getMessageConverters().add(0,
new MyStringHttpMessageConverter());
return restTemplate;
} static class MyStringHttpMessageConverter extends
StringHttpMessageConverter { List<Charset> acceptedCharsets = Arrays.asList(Charset.forName("GBK"),
Charset.forName("GB2312"), Charset.forName("GB18030"),
Charset.forName("UTF-8")); @Override
protected List<Charset> getAcceptedCharsets() {
return acceptedCharsets;
}
}
}
Socket方式:
加载hdfs中的模板文件,并转化为map形式嵌入项目中,存入内存缓存
import java.io.IOException;
import java.io.InputStream;
import java.util.HashMap;
import java.util.List;
import java.util.Map; import org.apache.commons.io.IOUtils;
import org.apache.commons.lang3.StringUtils;
import org.apache.hadoop.fs.FileSystem;
import org.apache.hadoop.fs.Path;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory; public class LoadHdfsTemplate {
static final Logger logger = LoggerFactory
.getLogger(LoadHdfsTemplate.class); protected FileSystem fileSystem; public final boolean checkFile(String filePath) {
boolean exists = false;
try {
Path path = new Path(filePath);
exists = fileSystem.exists(path);
} catch (IOException e) {
logger.error("模板文件不存在!", e);
} catch (Exception e) {
logger.error("", e);
}
return exists;
} public Map<String,Object> readHdfsFile(String hdfsPath) throws IOException{
Path path = new Path(hdfsPath);
InputStream in = fileSystem.open(path);
List<String> lines = IOUtils.readLines(in);
if(null == lines || lines.isEmpty()){
return null;
}
Map<String,Object> map = new HashMap<String,Object>();
int rowNum = 0;
for(String line : lines){
rowNum++;
String[] content = line.split(" ");
String code = content[0];
String template = content[1];
if(StringUtils.isEmpty(line) || StringUtils.isEmpty(template)){
logger.error("第{}条模板格式错误!内容为:{}",rowNum,line);
continue;
}
map.put(code, template);
}
return map; }
}
加载本地文件,用于测试
import java.io.File;
import java.io.IOException;
import java.util.HashMap;
import java.util.Map; import org.apache.commons.lang3.StringUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory; import com.google.common.base.Charsets;
import com.google.common.io.Files;
import com.google.common.io.LineProcessor; public class LoadTemplate{ final Logger logger = LoggerFactory.getLogger(LoadTemplate.class); private String filePath = "D:/template.txt"; public Map<String,Object> templateMap = new HashMap<String,Object>(); public Map<String, Object> loadTemplate() {
try {
File file = new File(filePath);
Integer lineCount = Files.readLines(file, Charsets.UTF_8,
new LineProcessor<Integer>() {
private int lineCount; public boolean processLine(String line)
throws IOException {
doSync(line);
lineCount++;
logger.debug("{} : {}", lineCount, line);
return true;
} public Integer getResult() {
return lineCount;
}
}); logger.info("读取{}行数据。", lineCount);
} catch (Exception e) {
logger.error("载入模板文件出错!", e);
}
return templateMap;
} private void doSync(String line) {
if(StringUtils.isEmpty(line)){
return;
} String[] content = line.split(" ");
String code = content[0];
String template = content[1];
templateMap.put(code, template);
}
}
解析发送的xml模板: (这里说明下,在系统调用时候,会传入调用的接口对应的模板,与封装的对应模板的值,与模板进行匹配封装)

parseMap.put("message", "<?xml version='1.0' encoding='gb18030'?>"+root.asXML());
return parseMap;
}

方法调用入口: 从xml解析获得的连接方式为socket或http及其Ip和port 进行相应连接,发送并返回请求数据,随之进行解析封装入map,供应用系统提取使用字段值。
import java.io.UnsupportedEncodingException;
import java.util.Map; import org.apache.commons.lang3.StringUtils;
import org.dom4j.DocumentException; import Http.HttpConnect;
import Socket.SocketClient; import temlateRead.ParseTemplate; public class InterFaceCall { public Map<String,Object> getMessage(Map<String,Object> map,String template){
if(null != map && StringUtils.isNotBlank(template) && !map.isEmpty()){
try{
//解析封装模板
ParseTemplate parse = new ParseTemplate();
Map<String,Object> sendData = parse.parseData(map,template);
//连接方式
String connectType = (String) sendData.get("RequestType");
String connectIp = (String) sendData.get("RequestIp");
String connectPort = (String) sendData.get("RequestPort");
if("socket".equals(connectType)){
String content = (String) sendData.get("message");
SocketClient socketClient = new SocketClient(connectIp,connectPort);
socketClient.sendData(content.getBytes());
byte[] res = socketClient.recvData();
String resultData = new String(res,"gb18030");
map = parse.parseXml(resultData);
}else if("http".equals(connectType)){
HttpConnect request = new HttpConnect();
String resultData = request.getMessages(sendData);
map = parse.parseXml(resultData);
}
}catch(DocumentException e){
map.put("errorMessage", e);
e.printStackTrace();
}catch (UnsupportedEncodingException e) {
map.put("errorMessage", e);
e.printStackTrace();
}catch(Exception e){
map.put("errorMessage", e);
e.printStackTrace();
}
}else{
map.put("errorMessage", "传入数据或模板不能为空"); } return map; } }
测试类:
public static void main(String args[]){
String cusUseCashAmount = "";
Map<String,Object> resultData = null;
String template = "";
LoadTemplate aaa = new LoadTemplate();
Map<String,Object> temp = aaa.loadTemplate();;
//从****接口获取用户可用取现金额
String cardNo = "";
template = (String) temp.get("****");
InterFaceCall DataMap = new InterFaceCall();
Map<String,Object> sendData = new HashMap<String,Object>();
String SeqNo = UUID.randomUUID().toString().replace("-", "");
sendData.put("TrxType", "10010");
......
resultData = DataMap.getMessage(sendData, template);
cusUseCashAmount = (String)resultData.get("value1");
}
整理还没有完善,异常处理以及压力测试还没有进行,有空还要重写下。
