Spring Security - Third Edition

WebSecurityExpressionHandler

WebSecurityExpressionHandler was removed in favor of using SecurityExpressionHandler<FilterInvocation>.

This means you may have the following:

WebSecurityExpressionHandler handler = ...

This needs to be updated to:

SecurityExpressionHandler<FilterInvocation> handler = ...

You can implement WebSecurityExpressionHandler like so:

public class CustomWebSecurityExpressionHandler implements WebSecurityExpressionHandler {      ...}

Then it must be updated to:

public class CustomWebSecurityExpressionHandler implements SecurityExpressionHandler<FilterInvocation> {     ...}
