4 - springboot-(REST_API_QUERY)

(Static)

how to use RequestMethod.POST, RequestMethod.PUT, RequestMethod.DELETE and RequestMethod.GET
you can experiment with JUNİT on PersonelClinicRestControllerTest.java (src/test/java/com/javaegitimleri/app/web/)

You can try runnuing anymethods with run as -> Junit Test in src/test/java/com/javaegitimleri/app/web/PersonelClinicRestControllerTest.java. 
Then you can look at changing data on localhost:8182/rest/personels

5 - springboot-with-h2-database (REST_API_QUERY) (jdbc with h2 database)

how to create schema, table and add data with jdbc in table. you can look src/main/resources/ data.sql & schema.sql.
how to use h2 database with jdbc.

Also You can try runnuing createPersonelTest, deletePersonelTest methods with run as -> Junit Test 
in src/test/java/com/javaegitimleri/app/web/PersonelClinicRestControllerTest.java.

6 - springboot-jpa-with-h2-database (REST_API_QUERY)

First you have to add spring-boot-starter-security dependency file in pom.xml.
look at application.properties file in src/main/resources/...

#you can change username and password. then you can try login proccessing
spring.security.user.name=celal

8 - SpringJPA-PostgreSQL-Example

first step Open pdAdmin 4, use SQL Editor and make a query to create customer table in database called Personels Also you can create any database called diffrent name.

CREATE TABLE customer(
    id BIGINT PRIMARY KEY     NOT NULL,
    firstname VARCHAR(20),
    lastname VARCHAR(20)
);

second step

First you need to write localhost:8182/save
Then you can try writing bottom any link
localhost:8182/findall
localhost:8182/findbyid?id=3  
localhost:8182/findbylastname?lastname=Terim

9 - springboot-security-with-h2-example

How to use login process
Anybody has ROLE_EDITOR or ROLE_ADMIN can enter links called /rest/** and /actuator/** for AUTHORIZATION.Anybody only has ROL_USER can't enter links called /rest/** and /actuator/**

  • links -> localhost:8182/rest/personels, localhost:8182/rest/personel/3, localhost:8182/rest/personel?fn=Celal
  • links -> localhost:8182/actuator/health
INSERT INTO USERS VALUES('user1','{noop}12345',TRUE);
INSERT INTO USERS VALUES('user2','{noop}secrett',TRUE);
INSERT INTO USERS VALUES('celal','{noop}secret',TRUE);

you can write data below first-three sql queries instead of above sql queris in src/main/resources/data.sql

INSERT INTO USERS VALUES('user1','{bcrypt}$2a$10$FMQOTEUiRN1L2MV2gfYas.MEDnLcEffuenRme5WdFgkwcuWA2jyhG',TRUE);
INSERT INTO USERS VALUES('user2','{bcrypt}$2a$10$.qPu/z1bV0Lw5uSpv6YMKeiCUI4rsxfNY/HJJBgw9E7CYUULMW3CS',TRUE);
INSERT INTO USERS VALUES('celal','{bcrypt}$2a$10$m9RM8vLgWvu/8Ig21HURG.IHIeFEie8CsKaGV1FeQ88bi27Xz4wJS',TRUE);

username and password will be same again when you changed first-three lines in src/main/resources/data.sql.
for encrypted data you can look at PasswordEncoderTest.java class in src/test/com/javaegitimleri/ap/test for example (encrypted data)

  • 12345 -> {bcrypt}$2a$10$FMQOTEUiRN1L2MV2gfYas.MEDnLcEffuenRme5WdFgkwcuWA2jyhG
  • secrett -> {bcrypt}$2a$10$.qPu/z1bV0Lw5uSpv6YMKeiCUI4rsxfNY/HJJBgw9E7CYUULMW3CS
  • secret -> {bcrypt}$2a$10$m9RM8vLgWvu/8Ig21HURG.IHIeFEie8CsKaGV1FeQ88bi27Xz4wJS
