Go #1 - Running a go program

Go Install

go install
- When you run the above command, Go will compile the program and installs a binary in the bin location. For mac it is created at '/usr/local/go/bin/trygo' by default.

Steps:

- Move to your project folder using "cd projects/go/src/trygo"
- Run 'go install'
- You can execute the binary using '~/projects/go/bin/trygo'

Possible issues:

- Ran into the following issue when i ran the above command
go install trygo: open /usr/local/go/bin/trygo: permission denied
- I fixed it by changing the 'GOBIN' path in bashrc
export GOBIN=~/projects/go/bin

export PATH=$PATH:$GOBIN

Go Build

go build
- 'go build' is similar to 'go install' the only difference is it creates the binary inside the location you ran 'go build'
- To run the program you can just say 'trygo/trygo' (The first trygo is the location for the binary and trygo is the binary file generated by Go compiler)

Go Run

go run main.go
- One more way of running go program is using 'go run <--filename.go-->'
- 'go run' works very similar to 'go build/ go install' however instead of installing the program binary into 'GOBIN' or current directory, it compiles the file to a temporary location and runs from that location.
- So where is that temp location??? use the following command to find out
go run --work main.go

Happy coding ðŸ‘¨‍💻

Spring Boot - RestTemplate PATCH request fix

  In Spring Boot, you make a simple http request as below: 1. Define RestTemplate bean @Bean public RestTemplate restTemplate () { return new RestTemplate (); } 2. Autowire RestTemplate wherever you need to make Http calls @Autowire private RestTemplate restTemplate ; 3. Use auto-wired RestTemplate to make the Http call restTemplate . exchange ( "http://localhost:8080/users" , HttpMethod . POST , httpEntity , String . class ); Above setup works fine for all Http calls except PATCH. The following exception occurs if you try to make a PATCH request as above Exception: I / O error on PATCH request for \ "http://localhost:8080/users\" : Invalid HTTP method: PATCH ; nested exception is java . net . ProtocolException : Invalid HTTP method: PATCH Cause: Above exception happens because of the HttpURLConnection used by default in Spring Boot RestTemplate which is provided by the standard JDK HTTP library.

RADUS#4 - Caching the response in REST API's

  Caching in spring boot app: Caching can be used to provide a performance boost to your application users by avoiding the business logic processing involved again and again, load on your DB, requests to external systems if the users request data that's not changed frequently Different types of caching: We'll be focusing more on in-memory caching in this post i listed other options available to have an idea. In-memory caching You'll have a key-value data stores that stores the response of the request after it is served for the first time There are multiple systems like Redis, Memcached that do this distributed caching very well By default Spring provides concurrent hashmap as default cache, but you can override CacheManager to register external cache providers. Database caching Web server caching Dependencies needed: Maven < dependency > < groupId > org . springframework . boot </ groupId > < artifactId > spring - boot - starter - cache ...

Set BIND VARIABLE and EXECUTE QUERY programmatically in ADF

A very common scenario in ADF is to set a bind variable and execute query programmatically within AMImpl/ VOImpl classes. Here's a simple way to do this: To set bind variable for all rowsets:       ViewObjectImpl someVO = this.getSomeViewObject();       VariableValueManager vMngr = someVO.ensureVariableManager();        vMngr.setVariableValue("DefinedBindVariable",value);        someVO,executeQuery(); To set bind variable for default rowset:          ViewObjectImpl someVO = this.getSomeViewObject();          someVO.setNamedWhereClauseParam("DefinedBindVariable",value);          someVO,executeQuery();
