JSF注释不适用于Spring-boot [英] JSF annotations don't work with Spring-boot

问题描述

我曾尝试使用 Spring Boot和JSF/Primefaces/Richfaces ，但是对我来说，它是行不通的.

I had been tried to use info from Spring Boot and JSF/Primefaces/Richfaces, but for me it doesn't work.

我将Java 8，maven，Spring-boot和JSF与PrimeFaces结合使用. 我想要一个可执行jar并通过main方法或从命令行java -jar myApp.jar运行我的应用程序.

I use Java 8, maven, Spring-boot and JSF with PrimeFaces. I would like to have executable jar and run my application via main method or from command line java -jar myApp.jar.

问题-JSF注释(@ManagedBean，@ManagedProperty)被忽略.

The problem - JSF-annotations (@ManagedBean, @ManagedProperty) are ignored.

我也尝试添加/删除javax.el-api/javax.el/jstl-相同的结果.对于bean初始化，我已将部分添加到faces-config.xml

I also have tried to add/remove javax.el-api/javax.el/jstl - the same result. For bean initialization I have added section to faces-config.xml

当我将 spring-boot-starter-web 更改为 spring-boot-starter 并具有 spring-web 时(根据解决方案来自提到了Herick的帖子)我得到了

When I change spring-boot-starter-web to spring-boot-starter and have spring-web (according to solution from mentioned post from Herick) I got

java.io.FileNotFoundException:类路径资源 [org/springframework/web/servlet/config/annotation/WebMvcConfigurerAdapter.class] 无法打开，因为它不存在

java.io.FileNotFoundException: class path resource [org/springframework/web/servlet/config/annotation/WebMvcConfigurerAdapter.class] cannot be opened because it does not exist

我的配置类:

@Configuration
@EnableAutoConfiguration//(exclude = {WebMvcAutoConfiguration.class, DispatcherServletAutoConfiguration.class})
@ComponentScan("hello")
public class Application {

    public static void main(String[] args) {
        ConfigurableApplicationContext context = SpringApplication.run(Application.class);
    }

    @Bean
    public FacesServlet facesServlet() {
        return new FacesServlet();
    }

    @Bean
    public ServletRegistrationBean facesServletRegistration() {
        ServletRegistrationBean registration = new ServletRegistrationBean(facesServlet(), "*.xhtml");
        registration.setName("facesServlet");
        return registration;
    }

    @Bean
      public ServletListenerRegistrationBean<ConfigureListener> jsfConfigureListener()         {
          return new ServletListenerRegistrationBean<ConfigureListener>(new ConfigureListener());
      }

}

带有(exclude = {WebMvcAutoConfiguration.class, DispatcherServletAutoConfiguration.class})web.xml的配置不起作用. 在提到的帖子中是:

With (exclude = {WebMvcAutoConfiguration.class, DispatcherServletAutoConfiguration.class}) web.xml configuration doesn't work. In mentioned post was:

@Bean
public ListenerRegistationBean jsfConfigureListener() {
    return new ListenerRegistrationBean(new ConfigureListener());           
}     

ListenerRegistationBean在我的弹簧靴中不存在，而我改用了ServletListenerRegistrationBean.

ListenerRegistationBean is absent in my spring-boot and I have used ServletListenerRegistrationBean instead.

我的web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app 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 http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"     
    version="3.1">
    <display-name>Test</display-name>
    <servlet>
        <servlet-name>facesServlet</servlet-name>
        <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>facesServlet</servlet-name>
        <url-pattern>*.xhtml</url-pattern>
    </servlet-mapping>

    <welcome-file-list>
        <welcome-file>index.xhtml</welcome-file>
    </welcome-file-list>
    <error-page>
        <location>/error.xhtml</location>
    </error-page>
</web-app>

和faces-config.xml:

And faces-config.xml:

<?xml version="1.0" encoding="UTF-8"?>
<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 http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd"  
    version="2.2">
    <application>
        <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
    </application>

    <managed-bean>
      <managed-bean-name>managedBeann</managed-bean-name>
      <managed-bean-class>hello.ManagedBeann</managed-bean-class>
      <managed-bean-scope>session</managed-bean-scope>
    </managed-bean>
</faces-config>

因为使用了无效的注释. 顺便说一下PrimeFaces的工作方式.

Because nonworking annotations is used. By the way PrimeFaces is working.

我的目的是强制JSF注释起作用，因为在没有它们的真实项目中是不可能的.

My purpose is force JSF-annotation to work, because in real project without them it is impossible.

推荐答案

免责声明

即使我的答案与问题标题不匹配，我也会根据我认为您要达到的目标进行回答.

Disclaimer

I am answering this based on what I think you were trying to acheive even though my answer does not match the question title.

您说我的目的是强制JSF注释起作用，因为在没有它们的真实项目中这是不可能的."我猜你的意思是不可能的"，因为将受管bean放在faces-config.xml中很麻烦.因此，为此，我将不使用faces-config.xml来管理bean.

You said "My purpose is force JSF-annotation to work, because in real project without them it is impossible." I'm guessing you mean "impossible" because putting managed beans in the faces-config.xml is cumbersome. So to this end I am going to not use the faces-config.xml to manage beans.

我将向您展示一个使用Spring注释的替代方法，该方法非常简单，并且可以实现您的原始目标.

I'm going to show you an alternative that uses Spring annotations which is very non-cumbersome and I feel accomplishes your original goal.

示例- https://github.com/Zergleb/Spring-Boot-JSF-Example

前几天，我查看了您的问题，并决定尝试进行这项工作，然后将结果放在github(上面的链接)上.这个示例应该允许您使用Spring注释而不是JSF注释编写JSF应用程序，例如您将说

I looked over your question the other day and decided to try and make this work and I put my results on github (Link above). This example should allow you to write a JSF application using Spring annotations instead of JSF annotations for example you'll say

@Component
@Scope("view")
//The example above contains an implementation of the View Scope in Spring.

代替

@ManagedBean
@ViewScope

然后您将可以使用Spring进行所有依赖注入.

and you'll then be able to use Spring for all of your dependency injection.

我使用gradle而不是maven，这意味着您的依赖项位于build.gradle中，而不是pom.xml中，我必须添加它们才能使所有工作正常进行.这些应该足够容易以转换为我想象的pom.xml.

I used gradle instead of maven so this means your dependencies are in the build.gradle instead of the pom.xml I had to add these in order to make everything work. Those should be easy enough to translate to a pom.xml I imagine.

compile group: 'javax.el', name: 'el-api', version: '1.0'
compile group: 'com.sun.el', name: 'el-ri', version: '1.0'
compile group: "javax.servlet.jsp" name: "jsp-api" version: "2.1"

我的web.xml现在只有一个servlet，我删除了servlet映射以及web.xml的所有其他属性

My web.xml only has one servlet now and I removed the servlet-mapping and all of the other attributes of the web.xml

(我仍在研究如何删除此web.xml，一并检查示例是否有任何更新)

(I'm still working on how to remove this web.xml altogether check the example for any updates on whether I figured it out or not)

<web-app ... same as before>
    <servlet>
        <servlet-name>facesServlet</servlet-name>
        <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    </servlet>
</web-app>

faces-config.xml现在没有托管bean

faces-config.xml now has no managed beans

<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 http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd"  version="2.2">
     <application>
         <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
     </application>
</faces-config>

我现在还没有这个，但是我们可能要考虑在web.xml中留一个空，我还没有对此进行大量研究，但是github上的spring-project示例中包含了此代码

I do not have this right now but we might want to consider having an empty in the web.xml I haven't researched this a ton but one of the spring-project examples on github contains this code

我希望能回答您的问题.如果我遗漏了一些内容，请尝试参考示例代码.

I hope that answers your question. If I left something out try and reference the example code.

https://github.com/Zergleb/Spring-Boot-JSF-Example

运行一个Spring Boot应用程序，该应用程序应在一个共享公共上下文的应用程序中同时运行Spring MVC和JSF.(我将其包含在答案中，因为您在问题

Runs a spring boot application that should both run Spring MVC and JSF in one application sharing a common context.(I included this in the answer because you referenced this link in your question Spring Boot and JSF/Primefaces/Richfaces which says that mixing Spring MVC and JSF is impossible but I have working in my example code.
