将deltaspike添加到现有的primefaces maven项目后，WELD类加载问题

标签： jsf weld deltaspike classloading

我是新面孔和deltaspike，我们最初尝试过CDI对话但不得不回到deltaspike。我添加了https://deltaspike.apache.org/documentation/configure.html#config-maven-indep中提到的罐子但是我遇到了FacesMessages的类加载问题。我不知道如何解决这个问题。以下是日志和pom文件。

我明白这是根本原因   java.lang.LinkageError: Failed to link javax/faces/application/FacesMessage (Module "javax.faces.api:main" from local module loader @66133adc (finder: local module finder @7bfcd12c (roots: C:\Users\amoram\jbossstudio10\runtimes\jboss-eap\modules,C:\Users\amoram\jbossstudio10\runtimes\jboss-eap\modules\system\layers\base))): loader constraint violation: loader (instance of org/jboss/modules/ModuleClassLoader) previously initiated loading for a different type with name "javax/faces/application/FacesMessage"
  这是我的modules.xml在C：\ Users \ amoram \ jbossstudio10 \ runtimes \ jboss-eap \ modules \ system \ layers \ base \ javax \ faces \ api \ main下的内容，它也有我的jboss-jsf-api_2 .2_spec-2.2.12.redhat-1.jar

我想附加我的完整pom.xml文件，但不知道怎么做，它们太大了，不能像我上面做的modules.xml那样添加它们。有人可以指导我吗？

1 个答案:

答案 0 :(得分：0)

在我从控制器和服务类中注释掉javax.faces.application.FacesMessage及其所有出现后，错误消失了。看起来我们不能一起使用deltaspike和jsf-api FacesMessage，因为它们会造成歧义？
