Add Swagger to gradle SpringBoot application

Swagger is useful for contracts between controller and UI developer. Also, We can do TESTING the of the controller URLs with the help of swagger UI.

Add below steps to add swagger in graddle springboot App:

1.  gradle dependencies in build.gradle
        compile group: 'io.springfox', name: 'springfox-swagger2', version: '2.4.0'
compile group: 'net.bull.javamelody', name: 'javamelody-core', version: '1.54.0'
2. Create SwaggerConfig class in config package

SwaggerConfig.java:

@Configuration
@EnableSwagger2
public class SwaggerConfig {  
 @Bean
 public Docket newsApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .groupName(<packaage>)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("<controller_package>"))     
                .paths(PathSelectors.any())  
                .build();
    }

 private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title(<title>)
                .description(<description>)
                .termsOfServiceUrl("https://www.xyz.com/en/terms")
                .license("Xyz License")
                .licenseUrl("https://www.xyz.com")
                .version("1.0")
                .build();
    }
}

There are more option to configure Docket. above are commonly used.

3. To get the UI page for swagger
   Start springBoot project
Hit below URL:
http://<server>:<port>/<project_name>/swagger-ui.html



Congratullations!! Its done! !!

Shell script to deploy build and start SpringBoot project on Linux/Ubuntu

Provide the below paths at top in below test.sh file:

Step1: Run with gradlew

create below gradle.sh file.

gradle.sh :
export GRADLE_HOME=/opt/gradle/gradle-3.0;
export PATH="$PATH:$GRADLE_HOME/bin";
cd <PROJECT_HOME_PATH>;
gradle clean bootRun -PdebugPort=8000  --debug ;
---------------------------------------------------------------------

$sh gradle.sh  ---for runing sh file



Step2: Run with nohup, So we can close console

for Better use, create below folders:
-- /<my-dir>/checkouts - Here cheeckout/copy springboot project
--/<my-dir>/deployment - here we we will add bootPackage run details from /<my-dir>checkouts/<project>/build/app-classpath/* and /<my-dir>checkouts/<project>/build/libs/<project-version.jar>

Steps:
1. checkout gradle project in /<my-dir>/<gradle_project>
2.  go to /<my-dir>/<gradle_project> and run below commands

chmod +x gradlew
./gradlew clean eclipse
./gradlew clean bootRepackage -Pprofile=<local/qa9>

3. copy /<my-dir>checkouts/<project>/build/app-classpath/* to <my-dir>/deployment/<gradle_project_name>/config/ folder. here we need to create confiig folder before copy

4.copy  /<my-dir>checkouts/<project>/build/libs/<project-version.jar> to /<my-dir>/deployment/<project>/
5. go to  /<my-dir>/deployment/<project>/

6. Run below nohup command

nohup java -Dloader.path="config/*" -Xms256m -Xmx1024m  -jar <project-version.jar> --spring.config.location=config/<gradle_project_name>.yml --logging.config=config/log4j2-spring.yml --spring.profiles.active=<local/qa9> > console.log &


To automate above steps in shell script: below is deploy.sh file:

Steps:
1. Put this deploy.sh file in checkouts/<projectName>/ path
2. Make sure Checkouts and deployment folder at parallel
3. run sh deploy.sh <profile_name> command from terminal

deploy.sh:
--------------------------------
project_root_dir="$PWD"
profile=$1;
project_name=$( echo $project_root_dir | rev | cut -d/ -f1 | rev);
echo "Project name: $project_name";
deployment_dir=$project_root_dir/../../deployment;
echo "Deploy project profile : $profile";
echo "project root dir: $project_root_dir";

cd $project_root_dir;
pwd;

cd $deployment_dir;
pwd;
echo "Creating project folder in deployment";
echo "Removing config and jar";
rm -rf $project_name/config $project_name/content*.jar;
echo "Removed config and jar";
mkdir $deployment_dir/$project_name;
cd $deployment_dir/$project_name;
pwd;
ls;
mkdir config;
echo "Dir created :$project_root_dir/../../deployment/config ";


echo "Creating jar and config the springBoot project";
cd $project_root_dir;
chmod +x gradlew;
./gradlew clean eclipse;
./gradlew clean bootRepackage -Pprofile=$profile;
date;
echo "Copying jar and config folder to deployment folder";
cp -r $project_root_dir/build/app-classpath/*  $deployment_dir/$project_name/config;
echo "Copied $project_root_dir/../../deployment/$project_name/config";
cd $project_root_dir/../../deployment/$project_name/config;
ls -lart;

cp -r $project_root_dir/build/libs/content*.jar  $deployment_dir/$project_name/;
echo "Copied jar file";
cd $deployment_dir/$project_name;
ls -lart;
echo "Runing Jar Dir:$pwd";

echo "Running jar with nohup";

echo "nohup java -Dloader.path=config/* -Xms256m -Xmx512m  -XX:+PrintGCDetails -XX:+PrintGCDateStamps -Xloggc:"$project_name"_gc.log -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=5 -XX:GCLogFileSize=20000k -XX:+UseG1GC -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath="$project_name"_java_pid.hprof  -jar "$project_name"-1.0.0.jar --spring.config.location=config/"$project_name".yml --logging.config=config/log4j2-spring.yml --spring.profiles.active=$profile > console.log &";

nohup java -Dloader.path=config/* -Xms256m -Xmx512m  -XX:+PrintGCDetails -XX:+PrintGCDateStamps -Xloggc:"$project_name"_gc.log -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=5 -XX:GCLogFileSize=20000k -XX:+UseG1GC -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath="$project_name"_java_pid.hprof  -jar "$project_name"-1.0.0.jar --spring.config.location=config/"$project_name".yml --logging.config=config/log4j2-spring.yml --spring.profiles.active=$profile > console.log & 

tail -f console.log;

Angular 4 Introduction and Install

Introduction:

Site for Referrence : https://cli.angular.io/

Angular1 – based on MVC model

angular2 – based on component

angular4 – performance better than angular 2

npm - node package management

npm install -g @angular/cli

download and install npm – 3.10 greater

node -v

npm -v

ng -v

Creating project:

ng new <projectName> --skip-install

cd <projectName>

ng serve – for starting the app

localhost:4200 --by default

 -- To change port:

ng serve --host 0.0.0.0 --port 4201
