Requirements : Eclipse,Spring Tool Suite
Dependencies : Swagger, H2 Database, JPA,Web
Build Project with the help of STS so you
will get project structure like this. first
ensure that you must hdependencies
in pom.xml file.
After,that create a package and class according to given picture.
Pom.xml
SpringSwaggerJpaRestH2Application class
EmployeeRestController class
Employee class
EmployeeServiceImpl class
EmployeeRepository class
EmployeeService class
application.properties
copy this line in this file so that you configure H2 database will configure automatically in your application .and if you have any port problem like your port 8080 is used by some other resource then add server.port=8089 or any other port no. so that this app run.
spring.h2.console.enabled=true
spring.h2.console.path=/h2
server.port=8089
Now open H2 Databse with this url http://localhost:8089/h2/ in my case becuase i am using port no 8089.
make sure JDBC URL :jdbc:h2:mem:testdb otherwise u will get an error .then click on coonect then u will get an empty table called Employee. you can see by writing this query on it.
Now Test the Restful endpoints with swagger.
Url : http://localhost:8089/swagger-ui.html
Now click on employee-rest-controller then you will see operations and we will test all.
By Clicking on POST you can insert data into table.
Inserting into table click on Try it out. and when data is sucessfully inserted then you can see response code is 200.
Now check whether data is inserted into table or not go to H2 database.and run the command and the data is inserted into Employee table.
Test GET to see all employee details .
click on GET employee by id =1 and you will get details coressponding to that id.
you can update record of any Employee by providing id.
lets check the data is updated or not into table. yes updated
Test delete by Id =1
lets check the id =1 is deleted from table or not .yes its deleted.
