How to upgrade Jenkins on Ubuntu

upgrade a Jenkins on the Ubuntu

First, update the apt packages to fetch the latest versions

sudo apt-get update

Use the following commands to upgrade Jenkins:

sudo apt-get --only-upgrade install jenkins

And then restart the Jenkins server using the command

sudo systemctl restart jenkins

jsp 를 뷰로 사용한다면 다음과 같은 일이 발생할 수 있습니다.

session을 생성하지 않았지만.. jsp로 forwared 하는경우 즉 jsp 페이지를 어떠한 방법으로든 호출하는 경우

session이 자동으로 생성됩니다.

jsp 선언시 session=false로 설정해주세요.

<%@ page contentType="text/html;charset=UTF-8" language="java"  session="false" %>

그럼 session에 담긴 로그인 정보는 spring을 사용한다면 model에 담거나..

servlet/jsp를 사용한다면 request.setAttribute 형태로 담아서 사용하시면 되니다.

session=false 처리를 하지 않는다면.... session이 생성될 텐데.. 로그인 체크를 위해서는

1. session is null 인지 체크 하기 

2. session.getAttribute("user") is null 체크하기 

형태로 로직을 구현해야 합니다. 

Nginx Error:

upstream prematurely closed connection while reading response header from upstream

upstream prematurely closed connection while reading response header from upstream

    server {
        listen 80;
        location / {
            proxy_pass http://proxy_service;
            proxy_http_version 1.1;  // upstream 보낼 때 http 1.1로 ... 
            proxy_connect_timeout 5;
.....
        }

http 1.0

http 1.1

http 2.0

javax.validation을 이용해서 date형태의 날짜를 validation을 할 때 정규표현식을 이용할 수 있음

날짜가 문자열일 때 ( yyyy-mm-dd)

@Pattern(regexp ="^\\d{4}\\-(0[1-9]|1[012])\\-(0[1-9]|[12][0-9]|3[01])$",message = "eventDt는 yyyy-mm-dd 형식:2022=10-09과 일치해야 합니다.")
private String eventDt;

\d{4}\-(0?[1-9]|1[012])\-(0?[1-9]|[12][0-9]|3[01])*

등을 이용해서 검증할 수 있음.

timestamp값을 아래와 같이 사용하려면 .

{
  "statusCode": 404,
  "timestamp": "2022-11-24T14:32:53.553594",
  "message": "이벤트가 존재하지 않습니다."
}

1.해당 변수에 @DateTimeFormat annotation을 달고 직접 pattern을 설정합니다.

public class ErrorMessage {
    private int statusCode;
    @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    private LocalDateTime timestamp;
    private String message;

    public ErrorMessage(int statusCode, String message) {
        this.statusCode = statusCode;
        this.timestamp = LocalDateTime.now();
        this.message = message;
    }

    public int getStatusCode() {
        return statusCode;
    }

    public LocalDateTime getTimestamp() {
        return timestamp;
    }

    public String getMessage() {
        return message;
    }
}

2.application.properties에 jackson  serialization중 WRITE_DATES_AS_TIMESTAMPS 값을 false로  설정합니다.  

spring.jackson.serialization.WRITE_DATES_AS_TIMESTAMPS=false

기본 format 형태로 출력됩니다. 전체적으로 날짜 포멧이 아래와 같다면... .. 2번 방법으로.. 사용...

yyyy-MM-dd'T'HH:mm:ss

java.lang.IllegalArgumentException: An invalid domain [.xxxx.com] was specified for this cookie
과 같이 서브도메인 쿠키 생성시 아래와 같이 처리 해줘야 함.

tomcat context.xml에 다음과 같이 추가
<CookieProcessor className="org.apache.tomcat.util.http.LegacyCookieProcessor"/>

spring boot embead 일경우
@Bean
public EmbeddedServletContainerCustomizer tomcatCustomizer() {
    return container -> {
        if (container instanceof TomcatEmbeddedServletContainerFactory) {
            TomcatEmbeddedServletContainerFactory tomcat = (TomcatEmbeddedServletContainerFactory) container;
            tomcat.addContextCustomizers(context -> context.setCookieProcessor(new LegacyCookieProcessor()));
        }
    };
}

mapstruct + lombok 같이 사용하기 위해서는
