Could you please upgrade this project to use Spring Boot version 2.1.2.RELEASE?

When I do so I get the below error: https://stackoverflow.com/questions/54294450/feign-retryableexception-read-timed-out-executing-get-http-forex-service-curr

Table does not exist error.

Where do I put the create table command?

I am asking because I am getting a "Table not found" error. I searched online wherein all the examples use schema.sql to create the table in the H2 database. Is this something you missed or is there something I am missing due to which I get the "Table not found" error?

springfox-boot-starter version v3.0.0-SNAPSHOT unavailable in remote repository

The spring-boot-2-rest-service-with-swagger has a dependency error in pom.xml, where several IDE report of missing artifact io.springfox:springfox-boot-starter:jar:3.0.0-SNAPSHOT, and the project cannot not be built. The exact error on running mvn clean compile is:

[ERROR] Failed to execute goal on project spring-boot-2-rest-service-swagger: Could not resolve dependencies for project com.in28minutes.springboot.rest.example:spring-boot-2-rest-service-swagger:jar:0.0.1-SNAPSHOT: Failure to find io.springfox:springfox-boot-starter:jar:3.0.0-SNAPSHOT in https://repo.spring.io/snapshot was cached in the local repository, resolution will not be reattempted until the update interval of spring-snapshots has elapsed or updates are forced

The maven repository for springfox-boot-starter, shows the latest version to be 3.0.0. Using this version in the pom.xml file resolves the error and the build completes successfully.

Could you please guide : https://stackoverflow.com/questions/59700944/custom-header-approach-for-spring-boot-rest-api-versioning

How to fix it?

deprecated class NoOpPasswordEncoder in Spring boot security

The old AuthenticationManagerBuilders are no longer supported

				.roles("USER").and().withUser("admin1").password("secret1")
				.roles("USER", "ADMIN");```

They now need to be written as below.

```auth.inMemoryAuthentication()
			.withUser("user1").password("{noop}secret1").roles("USER")
			.and().withUser("admin1").password("{noop}secret1").roles("USER", "ADMIN");```

See ![this](https://stackoverflow.com/questions/50429483/spring-security-authentication-how-to-get-rid-of) solution on StackOverflow.

Not able to test http://localhost:8000/currency-exchange/from/EUR/to/INR

I created the forex microservice exactly as given in http://www.springboottutorial.com/creating-microservices-with-spring-boot-part-2-forex-microservice. I ran the appplication and tried to test the url http://localhost:8000/currency-exchange/from/EUR/to/INR, but getting the whilte lable error page. From postman I got the below response
{
"timestamp": "2018-10-21T16:08:58.060+0000",
"status": 404,
"error": "Not Found",
"message": "No message available",
"path": "/currency-exchange/from/EUR/to/INR"
}
What could be the issue?
