Examples of org.apache.struts2.config.MethodConfigurationProvider

org.apache.struts2.components.Anchor
MethodConfigurationProvider creates ActionConfigs for potential action methods that lack a corresponding action mapping, so that these methods can be invoked without extra or redundant configuration.
As a dynamic method, the behavior of this class could be represented as:
int bang = name.indexOf('!'); if (bang != -1) { String method = name.substring(bang + 1); mapping.setMethod(method); name = name.substring(0, bang); }
If the action URL is "foo!bar", the the "foo" action is invoked, calling "bar" instead of "execute".
Instead of scanning each request at runtime, the provider creates action mappings for each method that could be matched using a dynamic approach. Advantages over a dynamic approach are that:

    assert (body != null);


    try {
      writer.write(body);
    } catch (IOException e) {
      throw new StrutsException("IOError while writing the body: " + e.getMessage(), e);
    }
    if (popComponentStack) {
      popComponentStack();
    }
    return false;
