ASF GitHub Bot commented on WW-4875:
------------------------------------
aleksandr-m opened a new pull request #177: WW-4875 Add ability to use Java
based configuration
URL: https://github.com/apache/struts/pull/177
## WIP - Don't merge this yet!
### Things to todo / improve
- `Location` for java based configuration is currently `UNKNOWN`
- `ConstantConfig` for plugins (convention, rest, spring, etc)
- `unknownHandlerStack` configuration in current implementation is a list of
strings
### Usage
#### web.xml
```
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
<init-param>
<param-name>javaConfigClasses</param-name>
<param-value>com.example.AppConf</param-value>
</init-param>
</filter>
```
#### com.example.AppConf
```
public class AppConf implements StrutsJavaConfiguration {
@Override
public List<ConstantConfig> constants() {
ConstantConfig c = new ConstantConfig();
c.setDevMode(true);
c.setObjectFactory(customObjectFactory());
return Arrays.asList(c);
}
@Override
public List<BeanConfig> beans() {
List<BeanConfig> list = new ArrayList<>();
list.add(new BeanConfig(SomeBean.class));
list.add(customObjectFactory());
return list;
}
@Override
public List<String> unknownHandlerStack() {
return null;
}
private BeanConfig customObjectFactory() {
return new BeanConfig(CustomObjectFactory.class,
"customObjectFactory", ObjectFactory.class);
}
}
```

> Key: WW-4875
> URL: https://issues.apache.org/jira/browse/WW-4875
> Project: Struts 2
> Issue Type: Improvement
> Affects Versions: 2.5.13
> Reporter: Aleksandr Mashchenko
> Assignee: Aleksandr Mashchenko
> Fix For: 2.6
>
>
> Some people are allergic to XML and even with convention plugin currently
> there is no way to define properties w/o struts.xml or properties file.
> It would be great to add the ability to configure app via java configuration.
> We can start with adding support for constant, bean and unknown-handler-stack
> and see how it goes.
