I have a bean

<bean name="api.HelloWorld" class="ru.example.api.HelloWorld"/>

When you call in flow I get an error.

<evaluate expression="api.HelloWorld.test()"/>

How to call?

If you are using SpEL, you can use this:

<evaluate expression="@'api.HelloWorld'.test()"/>

if you are using OGNL or jboss-el, I don't think it can be done other than using a utility class, like this:

@Component
public class WebFlowUtil {

    @Autowired
    private ApplicationContext applicationContext;

    public Object getBean(String beanName) {
        return applicationContext.getBean(beanName);
    }
}

then use:

<evaluate expression="webFlowUtil.getBean('api.HelloWorld').test()"/>

  • did you escape the single quotes? – rptmat57 May 04 '16 at 12:04
  • anyway, it looks like you are using OGNL so I don't think it will work, as I stated in my answer – rptmat57 May 04 '16 at 12:04
  • added a workaround that should work with OGNL and jboss-el (tested with jboss-el) – rptmat57 May 04 '16 at 12:14
