流程：http请求获取传入的josn串，解析后放入jasper文件的变量里，生成pdf后返回成功。
service端根据解析的交易号分发请求：
import java.io.BufferedReader;
import java.io.IOException;
import java.io.OutputStream;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.log4j.Logger;
import net.sf.json.JSONObject;
import com.epsoft.zsb.common.CreatePdf;
/**
* http请求总入口，根据jyh分发业务处理
*/
public class DoTradeService extends HttpServlet{
CreatePdf pdf = new CreatePdf();
private static final long serialVersionUID = 1L;
static Logger logger = Logger.getLogger(DoTradeService.class); //First step
public DoTradeService() {
super();
}
public void destroy() {
super.destroy();
}
public void init() throws ServletException {
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("UTF-8");
response.setContentType("text/javascript");
BufferedReader reader = request.getReader();
char[] buf = new char[512];
int len = 0;
StringBuffer contentBuffer = new StringBuffer();
while ((len = reader.read(buf)) != -1) {
contentBuffer.append(buf, 0, len);
}
String varin = contentBuffer.toString();
logger.info("原始传入"+varin);
JSONObject jobj = JSONObject.fromObject(varin);
logger.info("json转换后:返回："+jobj);
String jyh = null;
jyh = jobj.getString("JYH");
System.out.println("交易号："+jyh);
if(jyh!=null||"".equals(jyh)){
if(jyh.equals("Si00101")){
String content = pdf.Si00101(jobj);
logger.info("Si00101:返回："+content);
OutputStream out = response.getOutputStream();
byte[] b = content.getBytes("UTF-8");
out.write(b);
out.flush();
out.close();
}
}
}
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request,response);
}
}
业务处理：
public class CreatePdf {
public String Si00101(JSONObject jojb){
JSONObject result = new JSONObject();
HashMap<String,Object> parameters = new HashMap<String,Object>();
parameters.put("bm", jojb.getString("bm"));
List<Object> prtList = new ArrayList();
JSONArray ListInfo = JSONArray.fromObject(jojb.getString("ListInfo"));
for(int i=0;i< ListInfo.size();i++){
JSONObject job = ListInfo.getJSONObject(i);
String[] tt = new String[17];
tt[0] = job.getString("xm");
prtList.add(tt);
}
String[] prtNames = new String[] {"xm"};
String[] xm = (String[]) prtList.get(0);
parameters.put("xm0000", xm[5]);
JRDataSource s1 = new ResultDataSource(prtList,prtNames);
File reportFile = new File("D:/zsb\\shbxzgzj.jasper");
JasperReport jasperReport = null;
try {
jasperReport = (JasperReport) JRLoader.loadObject(reportFile);
// JasperPrint print = JasperFillManager.fillReport(jasperReport, parameters, new JREmptyDataSource());
JasperPrint print = JasperFillManager.fillReport(jasperReport, parameters,s1);
JasperExportManager.exportReportToPdfFile(print, "D:/zsb\\shbxzgzj.pdf");
result.put("JYH", "Si00101");
result.put("RETMSG", 0);
result.put("ERRMSG", "");
}catch (Exception e){
// e.printStackTrace();
result.put("JYH", "Si00101");
result.put("RETMSG", -5);
result.put("ERRMSG",e.getMessage());
return result.toString();
}
return result.toString();
}
}
使用postma测试，测试json串为：
{
"bm":"研发部",
"ListInfo": [
{"xm":"张三"},
{"xm":"李四"},
{"xm":"王五"}
]
}
