How to update JSF 2.2 to JSF 2.3 using Maven in a Spring Application

问题:

I'm using MAVEN and already changed my pom.xml dependencies from:

<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> 

to:

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

but now I get a build error:

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]

I also updated the version in my faces-config.xml to 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> 

Are there more changes to make in the pom.xml or anywhere else in my application?

回答1:

Old question, but for people still facing this problem: To avoid the "Unable to find CDI BeanManager" error, it's important that your faces-config.xml version is not 2.3 and your web.xml version is not 4.0!

The Mojarra implementation ELUtils class contains the following nice bit of code:

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

When using lower versions, it skips this check, and works with Spring DI instead of CDI.

回答2:

1) Add CDI and weld dependency pom.xml

<dependency>     <groupId>javax.enterprise</groupId>     <artifactId>cdi-api</artifactId>     <version>1.2</version> </dependency>  <dependency>     <groupId>org.jboss.weld.servlet</groupId>     <artifactId>weld-servlet</artifactId>     <version>2.2.9.Final</version> </dependency> 

2) create beans.xml in WEB-INF

<?xml version="1.0" encoding="UTF-8"?> <beans     xmlns="http://java.sun.com/xml/ns/javaee"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xmlns:weld="http://jboss.org/schema/weld/beans"     xsi:schemaLocation="     http://java.sun.com/xml/ns/javaee http://jboss.org/schema/cdi/beans_1_0.xsd     http://jboss.org/schema/weld/beans http://jboss.org/schema/weld/beans_1_1.xsd">  <weld:scan>     <weld:exclude name="org.springframework.data.jpa.repository.cdi.**" />     <weld:exclude name="com.example.beans.**" /> </weld:scan>
