In this post, under Spring Retry I will show with example how to configure ExponentialBackOffPolicy 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 Service15 { 11…… Continue reading Configuring ExponentialBackOffPolicy (using annotations)
Creating and Parsing a asymmetric key signed JWT containing claims
In this post under JJWT, I will show with example how to create and parse asymmetric key signed JWT containing claims. Below is the complete code for your reference. Main class 1 package defaultPackage; 2 import java.security.KeyPair; 3 import java.security.PrivateKey; 4 import java.security.PublicKey; 5 import java.util.Date; 6 7 import io.jsonwebtoken.Claims; 8 import io.jsonwebtoken.Jws; 9 import…… Continue reading Creating and Parsing a asymmetric key signed JWT containing claims
AssertTimeout Example
In this post under Junit, I will show with example how to use and what is the purpose of AssertTimeout assertion method. AssertTimeout is used to verify whether a certain operation completes within the specified timeout or not. For our example we will use the below class to be tested. Class to be tested package…… Continue reading AssertTimeout Example
Creating and Parsing a asymmetric key signed JWT containing payload
In this post under JJWT, I will show with example how to create and parse asymmetric key signed JWT containin payload. The JWT can contain claims or payload. For our example we will use a JWT containing payload. Below is the complete code for your reference Main code 1 package defaultPackage; 2 import java.security.KeyPair; 3…… Continue reading Creating and Parsing a asymmetric key signed JWT containing payload
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 JWT, I will show with example how to create and parse a 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();2 3 jwtBuilder.header().add(“alg”,…… 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.parser(); jwtParserBuilder.unsecured();…… Continue reading Parsing simple unsigned JWT containing plaintext as payload
