最近在學(xué)習(xí)SpringBoot項(xiàng)目，項(xiàng)目模塊中有用到一些，做一個(gè)定時(shí)任務(wù)調(diào)度的功能，使用restful來簡單實(shí)現(xiàn)一下。

工程目錄結(jié)構(gòu)如下
工程目錄結(jié)構(gòu)
下面我們配置一下定時(shí)任務(wù)
啟動(dòng)類中假如 @EnableScheduling 注解來開啟任務(wù)調(diào)度
@SpringBootApplication
@EnableScheduling
public class SpringErnestfeiTimertaskApplication {
public static void main(String[] args) {
SpringApplication.run(SpringErnestfeiTimertaskApplication.class, args);
System.out.println("=======================Springboot實(shí)現(xiàn)定時(shí)任務(wù)客戶端demo=========================");
}
}
調(diào)度方法如下
@Component
public class TimerTasks {
private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");
@Resource
private UrlConfig config;
/**
* 定時(shí)任務(wù)上傳文件到服務(wù)器
* */
@Scheduled(cron = "0 0/1 * * * ?")
public void reportCurrentTime() {
Date date = new Date();
File uploadFile = new File(config.getGetFileDir()+"\\1.txt");
FileUploadClient.uploadPassFile(config.getServerUrl(),uploadFile);
System.out.println("{客戶端定時(shí)任務(wù)開啟每一分鐘發(fā)送一次}===>>>"+dateFormat.format(date));
}
}
使用HttpClinet實(shí)現(xiàn)客戶端調(diào)度，具體如下
/**
* 上傳文件
* serverUrl 上傳服務(wù)器地址
* file 上傳的文件
*
*/
public static void uploadFile(String serverUrl,File file0) {
CloseableHttpClient httpclient = HttpClients.createDefault();
try {
HttpPost httppost = new HttpPost(serverUrl);
FileBody file = new FileBody(file0);
StringBody token = new StringBody("1234567", ContentType.create("text/plain", Consts.UTF_8));
StringBody content = new StringBody(">>>{來自于客戶端傳來的文件}<<<", ContentType.create("text/plain", Consts.UTF_8));
MultipartEntityBuilder builder =MultipartEntityBuilder.create();
HttpEntity reqEntity = builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE)
.addPart("file", file)
.addPart("token", token)
.addPart("content",content)
.setCharset(CharsetUtils.get("UTF-8")).build();
httppost.setEntity(reqEntity);
long startTime=System.currentTimeMillis();
System.out.println("====開始執(zhí)行====" + startTime);
CloseableHttpResponse response = httpclient.execute(httppost);
try {
HttpEntity resEntity = response.getEntity();
if(resEntity!=null){
System.out.println("==resEntity=="+resEntity.getContent());
System.out.println("====中文亂碼檢測====");
System.out.println(EntityUtils.toString(resEntity, Charset.forName("UTF-8")));
}
EntityUtils.consume(resEntity);
long endTime=System.currentTimeMillis();
System.out.println("====結(jié)束執(zhí)行====" + endTime);
System.out.println("====執(zhí)行時(shí)間====" + (endTime - startTime));
} finally {
response.close();
}
} catch (ClientProtocolException e) {
System.out.println("====服務(wù)器端無法連接異常====");
e.printStackTrace();
} catch (IOException e) {
System.out.println("====服務(wù)器端無法連接異常====");
e.printStackTrace();
} finally {
try {
httpclient.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
服務(wù)端Contoller層處理客戶端調(diào)用處理
@RestController
public class FileUploadController {
@Resource
private UrlConfig config;
@PostMapping("uploadFile")
public Object uploadFile(@RequestParam(value = "file")MultipartFile file,@RequestParam(value = "token")String token,@RequestParam(value = "content",required = false)String content){
Map<String,Object> resMap = new HashMap<>(8);
System.out.println("{服務(wù)端接受內(nèi)容}===>>>"+content);
if(token.equals(config.getToken())){
System.out.println("{上傳的文件名為}===>>>"+file.getOriginalFilename());
resMap.put("status",200);
resMap.put("message","服務(wù)端返回=上傳成功，返回文件"+file.getOriginalFilename());
}else{
resMap.put("status",400);
resMap.put("message","服務(wù)端返回=上傳失敗，TOKEN校驗(yàn)失敗！");
}
return JSON.toJSONString(resMap);
}
}
讀取配置文件中的參數(shù)可以使用@ConfigurationProperties 和 @PropertySource 讀取配置文件，將參數(shù)加載成實(shí)例屬性。
@Component
@ConfigurationProperties(prefix = UrlConfig.PREFIX)
@PropertySource("classpath:baseConfig.properties")
public class UrlConfig {
public static final String PREFIX = "config";
private String serverUrl;
private String getFileDir;
private String token;
public void setToken(String token) {
this.token = token;
}
public String getToken() {
return token;
}
public void setServerUrl(String serverUrl) {
this.serverUrl = serverUrl;
}
public String getServerUrl() {
return serverUrl;
}
public void setGetFileDir(String getFileDir) {
this.getFileDir = getFileDir;
}
public String getGetFileDir() {
return getFileDir;
}
一個(gè)簡單的demo就輕松實(shí)現(xiàn)了客戶端向服務(wù)端定時(shí)發(fā)送文件的定時(shí)任務(wù)功能。不得不感慨SpringBoot的強(qiáng)大之處。
