QUESTION
I want log4j2-spring.xml to read a property from the application.properties file. But seems log4j2-spring.xml is unable to read this. I have read https://logging.apache.org/log4j/2.x/manual/lookups.html#SpringLookup to implement this.
I have seen this answer on this site. Tried like this as well. But it didn't help me.
My build.gradle is like this:
...ANSWER
Answered 2021-May-22 at 18:17The question is do you need Log4j configuration over Spring Cloud?
Problem
If not, I would say org.apache.logging.log4j:2.14.1 dependency is an overkill. It brings Spring Cloud dependencies that you won't need. In a way that I still didn't figure out, it also interfeeres with spring-boot-starter-log4j2 causing initialization of logging context multiple times and then as a sideffect you have this excpetion at the startup as property from Spring is not resolved.
Solution
Mind you don't need whole log4j-spring-cloud-config-client and even spring-boot-starter-log4j2.
Following dependencies will set up your logging context:
- log4j
- log4j-slf4j-impl
- log4j-spring-boot
I have put an example program in GitHub repository. Variable names are slightly changed and there are comments explaining what each dependency is for.

QUESTION
Here I have a array of emails and checked emails in object, on the basis of that I am showing checked emails in list. My question is How can we show checked emails on top on the basis of emails which I have in object.
e.g:
checkedEmails = {"demo1@yopmail.com": true,"demo4@yopmail.com": true,"demo5@yopmail.com": true}
and list of emails emails = [{"name": "demo1","email":"demo1@yopmail.com"},{"name": "demo3","email":"demo3@yopmail.com"}, {"name": "demo5","email":"demo5@yopmail.com"}, {"name": "demo2","email":"demo2@yopmail.com"}, {"name": "demo1","email":"demo1@yopmail.com"}, {"name": "demo6","email":"demo6@yopmail.com"}]
ANSWER
Answered 2021-May-21 at 14:40The easiest way is to use a couple of array with one keeping checked emails while another unchecked.
Then show checked on the top and unchecked under it like what you have do.
So, I think your problem is how to get this couple array and it's a simple algo problem.

in the header while making a GET
request to my /users
endpoint and according to the response we decide if the login is successful or not. If the login is successful (i.e the user exists at the endpoint) then we push to the component. But I want the user to only be able to access the
/projects
url if he's a valid user. How do I apply private routes
This is how my login page code looks function LogIn() {
...ANSWER
Answered 2021-May-17 at 10:10You can set a persistent value (e.g. isAuthenticated = true
) to your LocalStorage after a successful response of login. But make sure to remove the value after user logs out (e.g. isAuthenticated = false
). Then you can check the value each time the user changes his/her route.
I have added below some basic example for you -
