spring - 如何在 Spring 应用程序中使用 Maven 将 JSF 2.2 更新到 JSF 2.3

Question

我正在使用 MAVEN 并且已经将我的 pom.xml 依赖项更改为:

<dependency>
        <groupId>com.sun.faces</groupId>
        <artifactId>jsf-api</artifactId>
        <version>2.2.14</version>
        <scope>compile</scope>
    </dependency>
    <dependency>
        <groupId>com.sun.faces</groupId>
        <artifactId>jsf-impl</artifactId>
        <version>2.2.13</version>
        <scope>compile</scope>
        <optional>true</optional>
    </dependency>

至:

<dependency>
        <groupId>org.glassfish</groupId>
        <artifactId>javax.faces</artifactId>
        <version>2.3.0</version>
    </dependency>

但现在我收到构建错误:

javax.faces.FacesException: Unable to find CDI BeanManager at com.sun.faces.el.ELUtils.tryAddCDIELResolver(ELUtils.java:312) ~[javax.faces-2.3.0.jar:2.3.0] at com.sun.faces.el.ELUtils.buildFacesResolver(ELUtils.java:242) ~[javax.faces-2.3.0.jar:2.3.0] at com.sun.faces.application.ApplicationAssociate.initializeELResolverChains(ApplicationAssociate.java:484) ~[javax.faces-2.3.0.jar:2.3.0] at com.sun.faces.application.ApplicationImpl.performOneTimeELInitialization(ApplicationImpl.java:1404) ~[javax.faces-2.3.0.jar:2.3.0] at com.sun.faces.application.ApplicationImpl.getELResolver(ApplicationImpl.java:526) ~[javax.faces-2.3.0.jar:2.3.0] at com.sun.faces.config.ConfigureListener.contextInitialized(ConfigureListener.java:256) ~[javax.faces-2.3.0.jar:2.3.0] at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4725) [tomcat-embed-core-8.5.5.jar:8.5.5] at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5189) [tomcat-embed-core-8.5.5.jar:8.5.5] at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) [tomcat-embed-core-8.5.5.jar:8.5.5] at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1403) [tomcat-embed-core-8.5.5.jar:8.5.5] at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1393) [tomcat-embed-core-8.5.5.jar:8.5.5] at java.util.concurrent.FutureTask.run(FutureTask.java:266) [na:1.8.0_111] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) [na:1.8.0_111] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) [na:1.8.0_111] at java.lang.Thread.run(Thread.java:745) [na:1.8.0_111]

我还将我的 faces-config.xml 中的版本更新为 2.3:

<faces-config xmlns="http://xmlns.jcp.org/xml/ns/javaee"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd"
          version="2.3">
<application>
    <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
    <el-resolver>org.primefaces.application.exceptionhandler.PrimeExceptionHandlerELResolver</el-resolver>
</application>

<factory>
    <exception-handler-factory>org.primefaces.application.exceptionhandler.PrimeExceptionHandlerFactory</exception-handler-factory>
</factory>

是否需要在 pom.xml 或应用程序中的其他位置进行更多更改？

Answer 1

老问题，但对于仍然面临此问题的人来说:为了避免“无法找到 CDI BeanManager”错误，重要的是您的 faces-config.xml 版本不是 2.3 并且您的 web.xml 版本不是 4.0!

Mojarra 实现 ELUtils class包含以下漂亮的代码:

if (getFacesConfigXmlVersion(facesContext).equals("2.3") || getWebXmlVersion(facesContext).equals("4.0")) {
                throw new FacesException("Unable to find CDI BeanManager");
}

当使用较低版本时，它会跳过此检查，并使用 Spring DI 而不是 CDI。
