Difference between Spring's @RequestParam vs @PathVariable

ALSO CHECK: Spring Interview Questions

What is the difference between Spring's @RequestParam vs @PathVariable Annotations.
Let's first understand the purpose and usage of @RequestParam and @PathVariable.

@RequestParam annotation is used to get the request parameters from URI, also known as query parameters. e.g If we have an incoming request with order id – http://scrutinybykhimaanshu.com/posts?postId=72

Then we can read the get the postId, using @RequestParam like below

@RequestMapping("/posts")
public String getPostDetails(@RequestParam("postId") String postId) {
  return "postDetails";
}

The required=false can be used to make the query parameter optional. e.g

@RequestMapping("/posts")
public String getPostDetails(@RequestParam(value="postId", required=false) String postId) {
  return "postDetails";
}

How to use YAML with Spring Boot?

ALSO CHECK: Spring Interview Questions

What is YAML?
YAML stands for 'YAML Ain’t Markup Language'.

It is a human friendly data serialization standard for all programming languages. It is a superset of JSON, and as such is a very convenient format for specifying hierarchical configuration data.

YAML is more readable and it is good for the developers for read/write configuration files.

Spring Security-Part 4.3: Form Based Authentication

> > Previous Tutorial: Spring Security-Part 4.2

Form Based Authentication

• When we do basic authentication, we need to pass 'Authorization' in header (e.g, Authentication:Basic BASE_64_UserName:Password). Though the basic auth is simple and fast, it has one disadvantage that we can't logout.
• We can user form based authentication, in which user will enter user name and password and can logout whenever required.

To switch from Basic to Form based authentication, we need to update ApplicationSecurityConfig. In the configure() method instead of httpBasic(), we need to use formLogin().

Spring Security-Part 4.2: @PreAuthorize, @PostAuthorize, @Secured, @RoleAllowed, @EnableGlobalMethodSecurity annotations

< < Previous Tutorial : Spring Security-Part 4.1

Annotation Based Roles and Authorities/Permissions

In our previous tutorial we had configured the roles and authorities in ApplicationSecurityConfig (which extends WebSecurityConfigurerAdapter). We can do the same thing by using @PreAuthorize annotation.

Spring Security-Part 4.1: Spring Security

Let's create a new project from Spring Initializr https://start.spring.io/.

• Project: Maven Project
• Language: Java
• Spring Boot: 2.2.4
• Group: com.example
• Artifact: spring-security-demo
• Java Version: 8
• Dependencies: Spring Web

Generate the project and import it in either Eclipse/STS or IntelliJ.

Spring Security-Part 3 : Spring Security with JPA authentication and MySQL

Example of Spring Security with JPA authentication and MySQL
We will build a Spring boot project with Spring Security that will do database authentication using JPA and connect with MYSQL database.

Let's say we have a mysql database locally with database instance with name 'springsecurity'. This database has a table with a name 'user'. 'roles' has comma separated roles.

#SpringSecurity Part 3 : Spring Security Flow

In the Part 1 of #SpringSecurity tutorial, we learned the difference between Authentication and Authorization. In Part 2, we created a Basic Authentication implementation was explained.

In this section, we will understand Spring Security Flow.

Above diagram show, how Spring Security works internally.

How can we implement basic authentication in Spring?
For this let us create a Spring Starter Project titled 'BasicAuthentication' from STS, this project has only Spring Web dependency.

#SpringSecurity Part 2 : Creating a simple Spring security project (Basic Authentication)

In the Part 1 of #SpringSecurity tutorial, I explained the difference between Authentication and Authorization. Now let's see how can we implement basic authentication in Spring.

#SpringSecurity Part 1 : Authentication v/s Authorization

ALSO CHECK: Spring Interview Questions and Answers

Authentication and Authorization are often used in conjunction with each other in terms of security, especially when it comes to gaining access to the system. 

Authentication means confirming your own identity, while authorization means granting access to the system. We can say, authentication is the process of verifying who you are, while authorization is the process of verifying what you have access to.
