问题描述
我正在尝试使用Hibernate Validator 5.0.1和JSF2.2，但自mojarra 2.2.3版以来，它们的集成似乎已中断.我已经创建了一个小型应用程序来演示该问题并获取异常"javax.servlet.ServletException:表达式错误:命名对象:未找到javax.faces.Bean."在Tomcat 7.0.42上运行时.
I'm trying to use Hibernate Validator 5.0.1 and JSF2.2 but their integration seems to be broken since mojarra version 2.2.3. I've created small app to demonstrate the issue and get exception "javax.servlet.ServletException: Expression Error: Named Object: javax.faces.Bean not found." when running it on Tomcat 7.0.42.
还有其他人有这个问题吗?
Does anyone else have this problem?

推荐答案
我能够通过以下方式对其进行修复:
I was able to fix it this way:
public static final String BEANS_VALIDATION_AVAILABILITY_CACHE_KEY = "javax.faces.BEANS_VALIDATION_AVAILABLE";
@PostConstruct
private void init() {
FacesContext.getCurrentInstance().getExternalContext().getApplicationMap().remove(BEANS_VALIDATION_AVAILABILITY_CACHE_KEY);
FacesContext.getCurrentInstance().getExternalContext().getApplicationMap()
.put(BeanValidator.VALIDATOR_FACTORY_KEY, Validation.buildDefaultValidatorFactory());
}
