In this post under JJWT, I will show with example how to create and parse asymmetric key signed JWT. The JWT can contain claims or payload. For our example we will use a JWT containing claims. Below is the complete code for your reference Main Code 1 package defaultPackage; 2 import java.security.KeyPair; 3 import java.security.PrivateKey;…… Continue reading Creating and Parsing a asymmetric key signed JWT
Asserting the presence of a custom claim in JWT
In this post under JJWT, I will explain with example, how to verify or assert the presence of custom (user created and added) claim in JWT token. JJWT framework provides a method through which1) we can verify whether a custom claim exist in the JWT or not.2) we can verify whether a custom claim’s value…… Continue reading Asserting the presence of a custom claim in JWT
Asserting the presence of a standard claim in JWT
In this post under JJWT, I will explain with example, how to verify or assert the presence of standard claim in JWT token. JJWT framework provides a list of methods through which1) we can verify whether a standard claim exist in the JWT or not.2) we can verify whether a standard claim’s value is equal…… Continue reading Asserting the presence of a standard claim in JWT
AssertSame Example
In this post under JUnit, I will show with example the purpose of AssertSame assertion method. JUnit 5 has added new assertion method “assertSame” that checks for Object reference equality. How “assertSame” is different from “assertEquals” assertion method is that latter check for Object value equality whereas former checks for Object reference equality. Object value…… Continue reading AssertSame Example
Configuring UniformRandomBackOffPolicy (using annotations)
In this post, under Spring Retry I will show with example how to configure UniformRandomBackOffPolicy using annotations For our example we will use the below service class Service class 1 package defaultPackage; 2 3 import java.util.Date; 4 5 import org.springframework.retry.annotation.Backoff; 6 import org.springframework.retry.annotation.Retryable; 7 import org.springframework.stereotype.Service; 8 9 @Service 10 public class Service14 { 11…… Continue reading Configuring UniformRandomBackOffPolicy (using annotations)
Creating and Parsing a secret key signed JWT containing payload
In this post under JJWT, I will show with example how to create and parse a secret key signed JWT containing payload. As mentioned in previous posts we will use an instance of JwtBuilder to construct a JSON Web Token. Below is the code snippet for your reference Snippet 1 1 JwtBuilder jwtBuilder = Jwts.builder();…… Continue reading Creating and Parsing a secret key signed JWT containing payload
Parsing simple unsigned JWT containing plaintext as payload
In this post under JJWT, I will show with example how to parse unsigned JWT containing plaintext as payload instead of serialized Claims object. As shown in previous post under JJWT, whenever we need to parse a JWT string. We need to create an instance of “JwtParser” as shown below JwtParserBuilder jwtParserBuilder = Jwts.parserBuilder(); JwtParser…… Continue reading Parsing simple unsigned JWT containing plaintext as payload
Creating a simple unsigned JSON Web Token containing payload
In this post under JJWT, I will show with example how to generate unsigned JWT containing payload. In previous post under JJWT, I talked about JWT containing claims. So what is the difference between claims and payload. Its simple payload is noting but any String data, whereas claims is a map. Now with the difference…… Continue reading Creating a simple unsigned JSON Web Token containing payload
Creating and Parsing a secret key signed JWT containing claims
In this post under JWT, I will show with example how to create and parse a signed JWT containing claims. As mentioned in previous posts we will use an instance of JwtBuilder to construct a JSON Web Token. Below is the code snippet for your reference Snippet 1 1 JwtBuilder jwtBuilder = Jwts.builder(); 2 3…… Continue reading Creating and Parsing a secret key signed JWT containing claims
AssertDoesNotThrow Example
In this post under JUnit, I will explain with example what is the purpose and how to use “AssertDoesNotThrow” assertion method. AssertDoesNotThrow takes an executable code and assert that the method doesn’t throw any exception during execution. Below is the javadoc of “assertDoesNotThrow” exception public static void assertDoesNotThrow​(Executable executable) Where “Executable” is a functional interface…… Continue reading AssertDoesNotThrow Example
