In the case proposed by Diony , signing multiple elements by id, simply change the newSignedInfo to:
// Create the SignedInfo final List transforms0...I must admit that I don't understand transformations, so take my example code with a grain of salt. Also, signing a doc fragment by PATH does not work, simply because there's no way to identify the fragment with a URI without referring to it by id. Reference ode from org.jcp.xml.dsig.internal.dom.DOMURIDereferencer :
// Check if same-document URI and register...

Validation groups can be used to control which rules validation rules to run. A validation group can be identified by any Java interface (not class!). Multiple validation groups may be specified when validating. In this example, I added a validation group named MyValidationGroup ( src/main/java/com/example/MyValidationGroup.java in Maven project):
package com.example; public interface MyVal...and added a @Size rule for a person's name, because my database can only store up to 15 characters for a person's name:
package com.example; import javax.validatio...Now validate Person with a JUnit test ( src/test/java/com/example/TestPersonWithGroup.java in Maven project):
package com.example; import java.util.Set; ...Test with " mvn clean test ". The rules where groups is not specified, which belong to the javax.validation.groups.Default group, are not executed with these tests.

A bean class may also be defined through composition. The validation rules of referenced beans are not automatically called when a composite bean is validated. You need to use the @Valid annotation to trigger cascade validation. As an example, I create a class named AccountPerson2 , which contains a Person with the addition of an email field ( src/main/java/com/example/AccountPerson2.java in Maven project):
package com.example; import javax.validatio...Now validate AccountPerson2 with a JUnit test ( src/test/java/com/example/AccountPerson2Test.java in Maven project):
package com.example; import java.util.Set; ...Test with " mvn clean test " and you'll see that the validation rules of the Person class are executed when an AccountPerson2 bean is validated. Without the @Valid annotation, the validation rules of Person will not be called.

When a bean class inherits another class, the validation rules of the parent class is automatically executed when a child class bean is validated. As an example, I create a class named AccountPerson , which inherits the Person class with the addition of an email field ( src/main/java/com/example/AccountPerson.java in Maven project):
package com.example; import javax.validatio...Now validate AccountPerson with a JUnit test ( src/test/java/com/example/AccountPersonTest.java in Maven project):
package com.example; import java.util.Set; ...Test with " mvn clean test " and you'll see that the validation rules of the Person class are executed when an AccountPerson bean is validated.

In this simple example, I create a simple validating bean and create a JUnit test to test the validation. The bean ( src/main/java/com/example/Person.java ):
package com.example; import javax.validatio...The test ( src/test/java/com/example/TestPerson.java ):
package com.example; import java.util.Set; ...Run the test:
mvn clean testYou'll notice that one test passed and the other failed. The tests require that a person must have a name and the name cannot be empty, so @NotNull is not the right rule to use here. To make sure that the name is not empty, we need to use @Pattern . But since a null String matches any pattern, @NotNull is also needed:
package com.example; import javax.validatio...

The landing page after login can be configured with the default-target-url attribute of form-login . If a user was redirected to the login form after requesting a restricted URL, she's redirected to the original requested page after successful login. An easy configuration looks like this:
<beans:beans xmlns="http://www.springframework.org...But there are times that you want to do more initialization after login (such as loading user data), or apply more complex logic before redirecting. This is where the authentication-success-handler-ref attribute comes into play. You create a class that implements org.springframework.security.web.authentication.AuthenticationSuccessHandler and use that as the authentication-success-handler-ref :
<http entry-point-ref="authProcessFilterEn...This is a skeleton implementation:
public class MyAuthenticationSuccessHandler implem...
