This utility helps you to create a ready to run project with following:

1. Dropwizard app
2. Prometheus Metrics
3. MySql database support
4. Rest Apis (Json over HTTP 1.1)
5. Rest Apis (Proto-buf over HTTP 1.1)
6. Database health checks
7. EasyHttp support - easy http provides resilient http sync/async client https://github.com/harishb2k/easy/wiki/Http-Module

Generate Project

Configuration for creating project:

1. groupId - your project group id
2. artifactId - your project artifact id
3. package - package name for you for java source code

 mvn archetype:generate \
  -DarchetypeGroupId=io.github.devlibx.tools.java.maven \
  -DarchetypeArtifactId=project-generator \
  -DarchetypeVersion=2.0.8 \
  -DgroupId=com.dummy \
  -DartifactId=dummy-project \
  -Dpackage=com.dummy.pack \
  -DinteractiveMode=false

NOTE: If you want to crate Java 19 project go to this link. You will get the correct command to generate.
https://github.com/devlibx/java-project-generator/wiki/Java-19---Base-Project

See "Known Issue" to reformat the generated pom.xml to remove extra spaces.
>> cd <project>
>> xmllint --format pom.xml > pom.new ; mv pom.new pom.xml

Run Application

Create a sample DB

If you run mvn clean install then you also need the mysql database running since one of the test writes to the following table).

Modify Jdbc Url in following file: com.harish.dummy.persistence.base.PersistenceTestState.PersistenceTestContext

CREATE DATABASE users;
use users;
CREATE TABLE `users` (
   `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
   `name` varchar(265) DEFAULT NULL,
   PRIMARY KEY (`id`)
 );

> cd <new project dir which is created>

> mvn clean install -DskipTests
    Or
> mvn clean install 

# Update the DB related variable in config/run_local.sh file
> sh config/run_local.sh

Test you application

Calling sample api - Json

curl -X POST 'http://127.0.0.1:8080/api/v1/user' --header 'Content-Type: application/json' \
--data-raw '{
    "id": 1234
}'

Response:
{
    "id": 115,
    "some_data_from_external_http_service": {
        "userId": 1,
        "id": 1,
        "title": "some text",
        "body": "some text"
    }
}

Calling sample proto-buf api:

We support proto-buffer APIs with Json request. However, you should use proto-buf client to call this same api.

curl --location --request POST 'http://127.0.0.1:8080/api/v2/user' \
--header 'Content-Type: application/x-protobuf-json-format' \
--data-raw '{
  "input": "c99764c9-ef5f-4ac3-81be-b0887d0930aa"
}
'

Response:
{
    "status": "Ok",
    "string_passed_in_input": "c99764c9-ef5f-4ac3-81be-b0887d0930aa"
}

Known Issue:

The main pom.xml file may have extra spaces. You can reformat it online:

https://www.liquid-technologies.com/online-xml-formatter
Copy the pom.xml and remove unnessassery spaces

OR

If you have xmllint lint installed 
xmllint --format pom.xml > pom.new ; mv pom.new pom.xml

Generate from Source

If you want to generate this from soruce to customize then you can do from following:

git clone https://github.com/devlibx/java-project-generator.git
mvn clean install
