6- Creating First Project in STS

 

We are creating our first spring boot application which will have following REST APIs that will handle respective requests for our client to access-

1- A string that returns "Hello World" 

When client writes" http://localhost:8080/hello-world "

2- One Student information i.e(firstName and lastName) return in json

   When client writes "http://localhost:8080/student"

3- More than One Student information i.e(firstName and lastName) return

   When client writes "http://localhost:8080/students"

4- Return the student information we asked for 

   When client writes "http://localhost:8080/student/{firstName}/{lastName}"

  USE THE CONCEPT OF PATH VARIABLE

5- A REST API with concept of Queries in it

-----------------------------------------------

6- Also Explain Spring Boot Dev Tools,Lombok and Embedded Servers

DEPENDENCIES USED- Spring Web

@RestController Annotation

The java class with this annotation is used to access REST API using Browser..

@RestController is combination of @Controller and @ResponseBody

@Controller means controlling Response or to request access services

i.e- All this REST API inside this class should return xml or json or different representatin to the client.

GET -              Request to retrieve(find)  data

POST-             Request to create new data

PUT-               Request to update (change) data

DELETE-       Request  to delete (remove) data  

@ResponseBody annotaion uses HTTP converters to convert the return value to HTTP response Body.
