推荐答案

您没有提供太多信息，但是您的配置中肯定有错误. 提示:

You don't give too much information but you must have something wrong in your configuration. Tips:

• 错误的Spring或JSF版本或某些库卡在Tomcat库中.您正在使用任何类型的依赖项管理吗?您的spring-web-xxx.jar的确切版本是什么?您正在使用什么JSF实现?那是什么版本?

• 任何xml配置文件中的架构位置/版本错误.异常表明问题出在面孔配置上.它应该看起来像这样:

• Wrong Spring or JSF version or some library is stuck in Tomcat lib. Are you using any kind of dependency management? What is the exact version of your spring-web-xxx.jar? What JSF implementation are you using? What's the version of that one?

• Wrong schemalocation / version in any of your xml config files. Exception suggests the problem is with faces config. It should look like this:

<faces-config xmlns="http://java.sun.com/xml/ns/javaee"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
          version="2.0">
<application>
    <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
</application>

您可以在此处和此处.如果您无法解决问题，请发布一些配置文件. (appcontext.xml，web.xml，faces-config.xml)

You can find some examples here and here. If you are not able to resolve the issue, please post some of your config files. (appcontext.xml, web.xml, faces-config.xml)
