Converting XML configuration to java configuration in spring security for global method security

You could write a custom method security configruation, see Spring Security Reference:

5.10.2 GlobalMethodSecurityConfiguration

Sometimes you may need to perform operations that are more complicated than are possible with the @EnableGlobalMethodSecurity annotation allow. For these instances, you can extend the GlobalMethodSecurityConfiguration ensuring that the @EnableGlobalMethodSecurity annotation is present on your subclass. For example, if you wanted to provide a custom MethodSecurityExpressionHandler, you could use the following configuration:

@EnableGlobalMethodSecurity(prePostEnabled = true)
public class MethodSecurityConfig extends GlobalMethodSecurityConfiguration {
  @Override
  protected MethodSecurityExpressionHandler createExpressionHandler() {
      // ... create and return custom MethodSecurityExpressionHandler ...
      return expressionHandler;
  }
}

For additional information about methods that can be overridden, refer to the GlobalMethodSecurityConfiguration Javadoc.

Your modified code:

@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true)
public class MethodSecurityConfig extends GlobalMethodSecurityConfiguration {

    @Autowired
    private AccessDecisionManager accessDecisionManager;

    @Autowired
    private MethodSecurityExpressionHandler methodSecurityExpressionHandler;

    protected MethodSecurityExpressionHandler createExpressionHandler() {
        return methodSecurityExpressionHandler;
    }

    protected AccessDecisionManager accessDecisionManager() {
        return accessDecisionManager;
    }
}
