使用Java Conf配置Spring Wicket而不是xml

我很短的時間使用Spring，但是對於wicket我是新手。但我想嘗試一下這個框架。使用Java Conf配置Spring Wicket而不是xml

我想配置這兩個框架togheter。但我想避免使用xml配置文件。

我知道，檢票口可以這種方式進行配置，根據此：

http://wicket.apache.org/guide/guide/single.html#helloWorld_2 這：

https://github.com/bitstorm/Wicket-tutorial-examples/tree/master/SpringInjectionExample

但現在我得到的唯一錯誤：

看來你正在將Wicket與Spring Web MVC混合在一起。下面我貼我的一些代碼，或者你可以嘗試在GitHub上找到的東西：春季啓動+檢票：https://github.com/Pentadrago/spring-boot-example-wicket

我WebApplicationInitializer看起來是這樣的：

public class WebAppInitializer implements WebApplicationInitializer { 

    @Override 
    public void onStartup(ServletContext container) throws ServletException { 
     AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext(); 
     container.addListener(new ContextLoaderListener(context)); 
     context.register(ApplicationConfiguration.class); 

     FilterRegistration filter = container.addFilter("wicket.myproject", WicketFilter.class); 
     filter.setInitParameter("applicationClassName", WicketApplication.class.getName()); 
     filter.setInitParameter(WicketFilter.FILTER_MAPPING_PARAM, "/*"); 
     filter.addMappingForUrlPatterns(null, false, "/*"); 
    } 

}

的ApplicationConfiguration類使用有看起來像這樣：

@Configuration 
@ComponentScan 
public class ApplicationConfiguration { 

    @Bean 
    public TestService testService(){ 
     return new TestServiceImpl(); 
    } 

}

我繼承WebApplication類看起來是這樣的：

public class WicketApplication extends WebApplication { 

    @Override 
    public Class<? extends WebPage> getHomePage() { 
     return HomePage.class; 
    } 

    @Override 
    public void init() { 
     super.init(); 
     getComponentInstantiationListeners().add(new SpringComponentInjector(this)); 
    } 
}

在你的聚甲醛中，你應該有這個代表：
