如何将 Spring 引导 3 与 JSF 一起使用？
[英]How to use Spring boot 3 with JSF?
问题描述
I'm trying to create a JSF project managed by Spring boot 3.0.
我正在尝试创建一个由 Spring boot 3.0 管理的 JSF 项目。 But it doesn't work no matter how I do it.但不管我怎么做都行不通。 I can't find any example on the web.我在 web 上找不到任何示例。
My dependencies:我的依赖项：
implementation 'org.springframework.boot:spring-boot-starter-web:3.0.2'
implementation 'org.apache.tomcat.embed:tomcat-embed-jasper:10.1.5'
implementation 'org.glassfish:jakarta.faces:4.0.1'
testImplementation 'org.springframework.boot:spring-boot-starter-test:3.0.2'
My MainApplication class:我的主要应用程序 class：
@SpringBootApplication
public class ManagementClientApplication implements ServletContextAware {
public static void main(String[] args) {
SpringApplication.run(ManagementClientApplication.class, args);
}
@Bean
public ServletRegistrationBean<FacesServlet> servletRegistrationBean() {
ServletRegistrationBean<FacesServlet> servletRegistrationBean = new ServletRegistrationBean<>(new FacesServlet(), "*.xhtml");
servletRegistrationBean.setLoadOnStartup(1);
return servletRegistrationBean;
}
@Override
public void setServletContext(ServletContext servletContext) {
servletContext.setInitParameter("com.sun.faces.forceLoadConfiguration", Boolean.TRUE.toString());
servletContext.setInitParameter("jakarta.faces.FACELETS_SKIP_COMMENTS", "true");
}
}
My config webapp/WEB-INF/faces-config.xml:我的配置 webapp/WEB-INF/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/web-facesconfig_2_2.xsd"
version="2.2">
<application>
<el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver
</el-resolver>
</application>
</faces-config>
A test XHTML file:测试 XHTML 文件：
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://xmlns.jcp.org/jsf/html">
<h:head>
</h:head>
<h:body>
<h:form>
<h:outputText id="greeting" value="Hello world !" />
</h:form>
</h:body>
</html>

As written on Mojarra , you need more dependencies.正如Mojarra上所写，您需要更多依赖项。
implementation group: 'org.jboss.weld.servlet', name: 'weld-servlet-shaded', version: '5.1.0.Final'
Don't create FacesServlet yourself.不要自己创建 FacesServlet。 ServletContainerInitializer does that. ServletContainerInitializer就是这样做的。
But if you use embedded server, you should run two of them.但是如果你使用嵌入式服务器，你应该运行其中两个。 Because Spring Boot doesn't run the initializers.因为Spring Boot 不运行初始化程序。
@Bean
public ServletContextInitializer facesInitializer() {
return new JsfInitializer();
}
import org.jboss.weld.environment.servlet.EnhancedListener;
import org.springframework.boot.web.servlet.ServletContextInitializer;
import jakarta.servlet.ServletContainerInitializer;
import jakarta.servlet.ServletContext;
import jakarta.servlet.ServletException;
import com.sun.faces.config.FacesInitializer;
public class JsfInitializer implements ServletContextInitializer {
@Override
public void onStartup(ServletContext context) throws ServletException {
EnhancedListener cdiInitializer = new EnhancedListener();
cdiInitializer.onStartup(null, context);
ServletContainerInitializer facesInitializer = new FacesInitializer();
facesInitializer.onStartup(null, context);
}
}

Try:尝试：
implementation 'org.glassfish:jakarta.faces:3.0.4'
I did not figure out the root cause (conflict?) yet but, I have noticed that any versions above 3.0.4 cause the exception you are getting.我还没有找出根本原因（冲突？）但是，我注意到 3.0.4 以上的任何版本都会导致您遇到异常。 I got the same.我也一样。 This worked for me:这对我有用：
implementation 'org.springframework.boot:spring-boot-starter-web:3.0.1'
implementation 'org.glassfish:jakarta.faces:3.0.4'
providedRuntime 'org.apache.tomcat.embed:tomcat-embed-jasper:11.0.0-M6'
