#
@Past @Future只針對Date類型的驗證，如果是String類型的驗證，則不適用。
其實可以新加一個方法返回Date類型，再配合@Future@Past 進行驗證。
@Future(message = "Invalid CN_ID_INFO.EXPIRE_DATE.")
private LocalDate getValidExpireDate() {
try {
return LocalDate.parse(this.dateString, DateTimeFormatter.ofPattern("yyyy-MM-dd"));
} catch (Exception e) {
return null;
}
}
此方法對dateString進行解釋，返回LocalDate，如果dateString為空或格式錯誤，則返回空，再配合@Future 進行是否未來日期的驗證。
bean validation的注釋是針對單個變量的，如果要針對多個變量的聯動，則不行，需要用到這個注釋。
這種方法避免了自定義校驗器而增加類。
https://www.chkui.com/article/java/java_bean_validation
@AssertTrue(message = "Missing BANK_CARD_IMG_INFO.IMG")
private Boolean getValidImg() {
if(YNEnum.Y.code.equals(super.getNeedChecked())) {
return StringUtils.hasText(this.img);
}
return null;//igore checking.
}
這個是當needChecked為Y的時候才執行檢查img變量是否為空。
有幾點注意：
- 方法名稱要以get開頭
- 返回類型用Boolean，而不用boolean
- 返回值有三種：true,false,null如果是null則當成通過，與true的結果一樣
SPRING BOOT單元測試中，因為測試時可能對應的服務器地址不同于SIT等別的環境，通常會將這些地址放于application-sit.yaml中。
在單元測試的代碼中用這個標簽指定用哪個profile，如
@ActiveProfiles({"embedded-mongodb","test"})
但這樣做法，由于@ActiveProfiles這個標簽是final的，如果要測試別的profile，只能復制另一份單元測試代碼，再改此標簽。
比較靈活的做法是用default profile，default profile是如果沒指定任何profile，則會默認用這個。在application-default.yaml中再指定需激活的profile。
spring:
profiles:
active: test,embedded-mongodb
如果要測試別的profile，可以指定環境變量的方式覆蓋：
-Dspring.profiles.active=error,embedded-mongodb
為了安全起見，將application-default.yaml放在測試目錄中：src\test\resources。

接收數據的JAVA BEAN通常需要驗證其中字段的正確性，如不準為空，符合EMAIL格式等。
JSR-303 Bean Validation則提供了這樣的便捷。
只要在JAVA BEAN中需要驗證的字段加@NotNull這種標簽，然后在SERVISE中的輸入參數中加@Valid標簽，則就激活驗證流程。
也可以編程的方式自己驗證：
@MessageEndpoint
//@Validated
public class MqMessageCcdValidator {
private static final Logger LOGGER = LoggerFactory.getLogger(MqMessageCcdValidator.class);
@Autowired
private Validator validator;
@ServiceActivator
public MqMessage<CcdRequest> validate(/* @Valid */ Message<MqMessage<CcdRequest>> requestMessage) {
Set<ConstraintViolation<MqMessage<CcdRequest>>> set = validator.validate(requestMessage.getPayload());
if(CollectionUtils.isNotEmpty(set)) {
CompositeException compositeException = new CompositeException();
set.forEach(
constraintViolation -> {
LOGGER.info("{}", constraintViolation);
ReqInfoValidationException exception =
new ReqInfoValidationException(constraintViolation.getMessage());
compositeException.addException(exception);
}
);
throw new MessageHandlingException(requestMessage, compositeException);
}
return requestMessage.getPayload();
}
}
自定義驗證規則
可用標簽來做，以下為驗證手機號的規則：
import static java.lang.annotation.RetentionPolicy.RUNTIME;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.Target;
import javax.validation.Constraint;
import javax.validation.Payload;
import javax.validation.ReportAsSingleViolation;
import javax.validation.constraints.Pattern;
@Retention(RUNTIME)
@Target(value = { ElementType.FIELD, ElementType.PARAMETER, ElementType.ANNOTATION_TYPE })
@Constraint(validatedBy = {})
@ReportAsSingleViolation
@Pattern(regexp = "^1[3-9]\\d{9}$")
public @interface ChinaPhone {
String message() default "Invalid Chinese mobile No.";
Class<?>[] groups() default {};
Class<? extends Payload>[] payload() default {};
}

場景，餐廳：
- 食客下單，有飲品、食物、甜點
- 侍應接單，傳送給廚房
- 廚房分三個子流程處理，即飲品、食物、甜點子流程
- 等待三個子流程處理完，合并成一份交付
- 如果廚房發現某食物欠缺，會通知侍應，展開錯誤處理，即通知食客更改食物，再交給廚房
- 侍應將交付品傳送給食客
有一個主流程、三個子流程和一個聚合流程，聚合流程會聚合三個子流程的產物，通知主流程，再往下走。
并且主流程會感知子流程的錯誤，并會交給相應錯誤處理流程處理，且將結果再交給聚合流程。
對應SPRING INTEGRATION 的SCATTERGATHER模式：

return f -> f
.scatterGather(
scatterer -> scatterer
.applySequence(true)
.recipientFlow(f1 -> f1.transform(p -> "Sub-flow#1"))
.recipientFlow(f2 -> f2
.channel(c -> c.executor(taskExecutor))
.transform(p -> {
throw new RuntimeException("Sub-flow#2");
})),
null,
s -> s.errorChannel("scatterGatherErrorChannel"));
}
@ServiceActivator(inputChannel = "scatterGatherErrorChannel")
public Message<?> processAsyncScatterError(MessagingException payload) {
return MessageBuilder.withPayload(payload.getCause().getCause())
.copyHeaders(payload.getFailedMessage().getHeaders())
.build();
}

當需要調用第三方HTTP接口時，別人的接口還沒完成，可先根據接口定義文檔，返回適當的數據，以便開發。

有幾個項目中，都需要將圖片或者數字證書的文件轉為Base64，昨天寫代碼的時候，發現在jdk8中本就含有關于Base64的API。
從此后不再需要其他的jar包來轉換Base64了!!!
據說是JDK8加入的。
先是將文件轉為Base64：
public String encryptToBase64(String filePath) {
if (filePath == null) {
return null;
}
try {
byte[] b = Files.readAllBytes(Paths.get(filePath));
return Base64.getEncoder().encodeToString(b);
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
Files、Paths類是JDK7里加入的，讀取文件不再需要調用IO包里的FileInputStream，簡單便捷。
字符串參數filePath是文件的路徑。
首先是將文件讀成二進制碼，然后通過Base64.getEncoder().encodeToString()方法將二進制碼轉換為Base64值。
然后是將Base64轉為文件：
public String decryptByBase64(String base64, String filePath) {
if (base64 == null && filePath == null) {
return "生成文件失敗，請給出相應的數據。";
}
try {
Files.write(Paths.get(filePath), Base64.getDecoder().decode(base64),StandardOpenOption.CREATE);
} catch (IOException e) {
e.printStackTrace();
}
return "指定路徑下生成文件成功！";
}
字符串參數base64指的是文件的Base64值，filePath是指的文件將要保存的位置。
通過Files.write()方法輕松將文件寫入指定位置，不再調用FileOutStream方法。
第三個參數StandardOpenOption.CREATE是處理文件的方式，我設置的是不管路徑下有或沒有，都創建這個文件，有則覆蓋。
在StandardOpenOption類中有很多參數可調用，不再累贅。
摘要: 2020年是最近歷史上前所未有的一年。在過去的一百年中，人類沒有經歷過像COVID-19這樣的全球性大流行。它影響了我們星球上的所有國家，部門和幾乎所有個人。
好消息是，我們已經準備好疫苗，終于可以充滿樂觀和希望，迎接新的一年2021年。
2020年對于軟件開發行業來說是重要的一年，在許多領域都取得了明顯的突破。COVID-19大大加快了數字化轉型，到2021年這種趨勢將更加明顯。
