最后，我按照here的说明在Spring Boot环境中成功引导了Weld。对于使用Mojarra的JSF和使用Jersey的Web服务，CDI都没有问题。
但是现在我在我的应用程序中尝试包含Omnifaces 2.6时遇到了一个问题。
我的应用程序启动失败并显示以下消息：

答案 0 :(得分：1)
如@BalusC所述，这是初始化顺序的问题。
我正在使用：
import org.jboss.weld.environment.servlet.Listener;
@SpringBootApplication
public class MyApplication
{
public static void main(String[] args)
{
SpringApplication.run(MyApplication.class, args);
}
@Bean
public Listener weldListener()
{
return new Listener();
}
}
因此它被初始化为在JSF初始化之后运行的servlet上下文侦听器。
我改变了我的代码：
@Bean
public ServletContextInitializer weldServletContextInitializer()
{
return new WeldServletContextInitializer();
}
而不是weldListener()，而WeldServletContextInitializer是：
import javax.servlet.ServletContainerInitializer;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import org.jboss.weld.environment.servlet.EnhancedListener;
import org.springframework.boot.web.servlet.ServletContextInitializer;
public class WeldServletContextInitializer implements ServletContextInitializer
{
private ServletContainerInitializer servletContainerInitializer;
@Override
public void onStartup(ServletContext servletContext) throws ServletException
{
ServletContainerInitializer servletContainerInitializer = getServletContainerInitializer();
servletContainerInitializer.onStartup(null, servletContext);
}
private ServletContainerInitializer getServletContainerInitializer()
{
if (servletContainerInitializer == null)
servletContainerInitializer = new EnhancedListener();
return servletContainerInitializer;
}
}
现在Omnifaces 2.x开始没有问题。
修改：
需要通过org.omnifaces.ApplicationInitializer初始化Omnifaces，它是在这个bean中完成的：
@Bean
public ServletContextInitializer omnifacesServletContextInitializer()
{
return new OmnifacesServletContextInitializer();
}
OmnifacesServletContextInitializer的位置：
import javax.servlet.ServletContainerInitializer;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import org.omnifaces.ApplicationInitializer;
import org.springframework.boot.web.servlet.ServletContextInitializer;
public class OmnifacesServletContextInitializer implements ServletContextInitializer
{
private ServletContainerInitializer servletContainerInitializer;
@Override
public void onStartup(ServletContext sc) throws ServletException
{
ServletContainerInitializer servletContainerInitializer = getServletContainerInitializer();
servletContainerInitializer.onStartup(null, sc);
}
private ServletContainerInitializer getServletContainerInitializer()
{
if (servletContainerInitializer == null)
servletContainerInitializer = new ApplicationInitializer();
return servletContainerInitializer;
}
}
