1.下载需要的客户端、服务端Jar，客户端jar包链接： https://github.com/zhangliqingyun/jarlist/tree/master/webserviceclient 服务端jar包链接：https://github.com/zhangliqingyun/jarlist/tree/master/webserviceservice
2.配置web service服务，实现客户端与服务端通信
（1）web.xml内容
<display-name>xxfw</display-name>
<servlet>
<servlet-name>Way REST Service</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param> <!—初始化服务à
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>com.rdtsw.service</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet>
<description></description>
<servlet-name>MsgSevlet</servlet-name>
<servlet-class>com.rdtsw.action.MsgSevlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Way REST Service</servlet-name>
<url-pattern>/ws/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>MsgSevlet</servlet-name>
<url-pattern>/MsgSevlet</url-pattern>
</servlet-mapping>（2）服务类
@Path("/msg")
public class MsgService（3）服务器端接收文件代码
//文件接收
@POST
@Path("/RecXMLData/{fileName}")
@Produces({"application/json;charset=utf-8","text/plain"})
public String receiveFile(@PathParam("fileName") String fileName, @Context HttpServletRequest request, @Context HttpServletResponse response) {
try {
FileOutputStream fos = new FileOutputStream(new File(path + fileName));
byte[] buffer = new byte[8096];
InputStream is = request.getInputStream();
int len;
while ((len = is.read(buffer)) != -1)
{
fos.write(buffer, 0, len);
}
fos.flush();
fos.close();
return "ok";
} catch (Exception e) {
return "no"; }
}（4）服务器端发送文件
//文件发送
@POST
@Path("/SendXmlData/{fileName}")
@Produces({"application/json;charset=utf-8","text/plain"})
public String sendFile(@PathParam("fileName") String fileName, @Context HttpServletRequest request, @Context HttpServletResponse response) {
try {
File testFile = new File(path + fileName);
FileInputStream fi = new FileInputStream(testFile);
byte[] buf = new byte[2048];
DataOutputStream dos = new DataOutputStream(response.getOutputStream());
dos.writeUTF(testFile.getName());
int len1;
while ((len1 = fi.read(buf)) != -1)
{
dos.write(buf, 0, len1);
}
dos.flush();
dos.close();
fi.close();
return "200";
} catch (Exception e) {
return "404"; }
}（5）客户端发送文件
public static void send(String fileName,String deskUrl){
//String filename = "bbb.xml";
HttpClient ht = new DefaultHttpClient();
HttpPost post = new HttpPost("http://192.168.0.123:9080/xxfw/ws/msg/SendXmlData/"+fileName);
HttpResponse rs = null;
try {
rs = ht.execute(post);
DataInputStream is = new DataInputStream(rs.getEntity().getContent());
byte[] buffer = new byte[2048];
int len2;
//读出文件名
String filename = is.readUTF();
FileOutputStream fos = new FileOutputStream(new File(deskUrl+filename));
while((len2=is.read(buffer))!=-1){
fos.write(buffer, 0, len2);
}
fos.flush();
fos.close();
is.close();
} catch (Exception e) {
e.printStackTrace();
}finally{
System.out.println("文件发送成功");
post.abort();
}
}（6）客户端接收文件
public static void receive(String fileName,String deskUrl) throws JSONException, URISyntaxException, FileNotFoundException{
//String filename = "bbb.xml";
Client c = Client.create();
URI u =new URI("http://192.168.0.123:9080/xxfw/ws/msg/RecXMLData/"+fileName);
WebResource resource = c.resource(u);
MultivaluedMapImpl params = new MultivaluedMapImpl();
File testFile = new File(deskUrl+fileName);
FileInputStream fis = new FileInputStream(testFile);
String aaa = resource.entity(fis).post(String.class);
System.out.println("result:"+aaa);
}（7）客户端传递参数
public static void regist() throws URISyntaxException{
Client client = Client.create();
URI u = new URI(getUrl("RegJY4GSvr"));
WebResource resource = client.resource(u);
MultivaluedMapImpl params = new MultivaluedMapImpl(); //传递多个参数的方法
params.add("xh", "炫号");
params.add("zclx", "注册类型");
params.add("imei", "imei");
String result = resource.queryParams(params).get(String.class);
System.out.println(result);
}（8）服务端接收参数
//注册服务
@GET
@Path("RegJY4GSvr")
@Produces({"text/plain"})
public String regist(@QueryParam("xh") String xh,@QueryParam("zclx") String zclx,@QueryParam("imei") String imei,@Context HttpServletRequest request,@Context HttpServletResponse response){
java.util.Date now = new java.util.Date();
String registDate = format.format(now); //注册日全部
String zcdwdm = "000001"; //注册单位代码
map.put("xh", xh);
map.put("zclx", zclx);
map.put("imei", imei);
map.put("zcrq", registDate);
map.put("zcdwdm", zcdwdm);
try {
xxfwDao.insertRegist(map);
} catch (Exception e) {
e.printStackTrace();
}
return "注册成功";
}（9）客户端接收服务端反回的list集合
public static void init() throws URISyntaxException{
ClientConfig clientConfig = new DefaultClientConfig();
clientConfig.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, Boolean.TRUE);
Client client = Client.create(clientConfig);
MultivaluedMapImpl params = new MultivaluedMapImpl();
String zcdwdm ="000001";
String xxlx = "xxlx";
params.add("zcdwdm", zcdwdm);
params.add("xxlx", xxlx);
WebResource resource = client.resource(getUrl("InitJY4GSvr")); //得到注册服务初始化的url
GenericType<List<Demo>> hsp = new GenericType<List<Demo>>(){}; //返回结果集合类型
List<Demo> dwdmList= resource.queryParams(params).get(hsp); //单位代码和油料代码的集合
System.out.println(dwdmList.get(0).getYldmList().get(0).getYldm()); （10）服务端返回list集合
//得到单位代码
@GET
@Path("InitJY4GSvr")
@Produces({ MediaType.APPLICATION_JSON,MediaType.APPLICATION_XML})
public Response InitJY4GSvr(@QueryParam("zcdwdm") String zcdwdm,@QueryParam("xxlx") String xxlx, @Context HttpServletRequest request, @Context HttpServletResponse response){
map.put("zcdwdm", zcdwdm);
map.put("xxlx", xxlx);
List<Demo> list = new ArrayList<Demo>();
try {
List<Dwdm> dwdmList = xxfwDao.getDwdmList(map); //得到单位代码集合
List<Yldm> yldmList = xxfwDao.getYldmList(map); //得到油料代码集合
Demo demo = new Demo();
demo.setDwdmList(dwdmList);
demo.setYldmList(yldmList);
list.add(demo);
GenericEntity entity = new GenericEntity<List<Demo>>(list) {}; //返回结果类型
return Response.ok(entity).build();
} catch (Exception e) {
e.printStackTrace();
}
return null;
