问题：

Spring 没有配置JSF 的文档 该如何配置spring boot JSF

 

解决：

https://github.com/giant35/springbootjsf

 

有几个关键点： 1. pom.xml 加 jsf-impl & jsf-api & tomcat-embed-jasper &jstl；2. 注册JSF Servlet ；3. 添加faces-config.xml ; 4. 添加 xhtml 页面 ； 5. 添加 Beans

1. pom 添加JSF

2. 提供 ServletRegistrationBean Bean
   
   package com.enjoylearn.springbootjsf; import com.sun.faces.config.ConfigureListener; import javax.faces.webapp.FacesServlet; import javax.servlet.ServletContext; import org.springframework.boot.web.servlet.ServletListenerRegistrationBean; import org.springframework.boot.web.servlet.ServletRegistrationBean; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.web.context.ServletContextAware; /** * * @author sihai */ @Configuration public class JSFConfig implements ServletContextAware{ @Bean public ServletRegistrationBean facesServletRegistration() { ServletRegistrationBean registration = new ServletRegistrationBean( new FacesServlet(), "*.jsf"); registration.setLoadOnStartup(1); return registration; } @Bean public ServletListenerRegistrationBean<ConfigureListener> jsfConfigureListener() { return new ServletListenerRegistrationBean<>( new ConfigureListener()); } @Override public void setServletContext(ServletContext sc) { sc.setInitParameter("com.sun.faces.forceLoadConfiguration", Boolean.TRUE.toString()); } }

3. src/main/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>

4. src/main/webapp/test2.xhtml

5. src/main/java/***/ HelloController.java
   
   package com.enjoylearn.springbootjsf; import org.springframework.context.annotation.Bean; import org.springframework.stereotype.Component; /** * * @author sihai */ @Component("hh") public class HelloController { public String getMsg(){ return "你好啊啊"; } }

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

   package com.enjoylearn.springbootjsf;   import org.springframework.context.annotation.Bean; import org.springframework.stereotype.Component;   /** * * @author sihai */ @Component("hh") public class HelloController {     public String getMsg(){         return "你好啊啊";     } }

   
    
6. App.java
   
   package com.enjoylearn.springbootjsf; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; /** * * @author sihai */ @SpringBootApplication public class App { public static void main(String[] argv){ SpringApplication.run(App.class, argv); } }
