Spring 2.7.1与JSF2.2 (Mojarra)和Primefaces 6.2.9集成
Spring 2.7.1与JSF2.2 (Mojarra)和Primefaces 6.2.9集成
提问于 2022-06-30 07:09:41
我已经用下面的堆栈设置了工作-
Spring 5
JSF Mojarra 2.2.14
原面6.2.9
- 这个应用程序是作为WAR构建的。
- 有配置FacesServlet以服务*.xhtml请求的web.xml。JSF和Primefaces的所有init参数都定义为web.xml中的上下文params，
- 也有faces-带有SpringBeanFacesELResolver的config.xml用于所有JSF托管Beans以及@ManagedProperty和JSF作用域。托管bean使用@managedproperty获取对Spring的引用，并进行服务调用以填充JSF类中显示的数据。pages.
- @ManagedBean类还使用@PostConstructforinitialization.
这在weblogic应用服务器和tomcat中都运行得很好。
我们正在尝试使用最新的2.7.1版本将其转换为Spring引导项目。作为这个的一部分
- web.xml已被java配置类替换，如下所示-
@SpringBootApplication(scanBasePackages = {"com.demo.spring.boot.jsfprimefaces","com.xxx.eee"})
@ImportResource({"classpath:spring-root-config.xml","classpath:spring-security-config.xml","classpath:spring-restclient-config.xml"})
public class JsfPrimefacesApplication implements ServletContextInitializer {
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
servletContext.setInitParameter("com.sun.faces.forceLoadConfiguration", Boolean.TRUE.toString());
// Set JSF/Primefaces init params
servletContext.setInitParameter("javax.faces.DEFAULT_SUFFIX", ".xhtml");
servletContext.setInitParameter("javax.faces.STATE_SAVING_METHOD", "client");
servletContext.setInitParameter("javax.faces.PROJECT_STAGE", "Production");
servletContext.setInitParameter("javax.faces.VALIDATE_EMPTY_FIELDS", "false");
servletContext.setInitParameter("javax.faces.FACELETS_SKIP_COMMENTS", "true");
//servletContext.setInitParameter("javax.faces.CONFIG_FILES", "/WEB-INF/faces-config.xml");
servletContext.setInitParameter("javax.faces.DATETIMECONVERTER_DEFAULT_TIMEZONE_IS_SYSTEM_TIMEZONE", "true");
servletContext.setInitParameter("primefaces.THEME", "aristo");
servletContext.setInitParameter("primefaces.PUBLIC_CAPTCHA_KEY", "DDDDD");
servletContext.setInitParameter("primefaces.PRIVATE_CAPTCHA_KEY", "EEEEE");
servletContext.setInitParameter("primefaces.UPLOADER", "commons");
FacesInitializer facesInitializer = new FacesInitializer();
facesInitializer.onStartup(null, servletContext);
}
public static void main(String[] args) {
SpringApplication.run(JsfPrimefacesApplication.class, args);
}
}很少有其他@配置类-
@Configuration
public class PortalFilterConfiguration {
@Bean
public FilterRegistrationBean<RewriteFilter> rewriteFilter() {
FilterRegistrationBean<RewriteFilter> rwFilter = new FilterRegistrationBean<RewriteFilter>(new RewriteFilter());
rwFilter.setDispatcherTypes(
EnumSet.of(DispatcherType.FORWARD, DispatcherType.REQUEST, DispatcherType.ASYNC, DispatcherType.ERROR));
rwFilter.addUrlPatterns("/*");
return rwFilter;
}
}@Configuration
public class PortalListenerConfiguration {
@Bean
public ServletListenerRegistrationBean<JsfApplicationObjectConfigureListener> jsfConfigureListener() {
return new ServletListenerRegistrationBean<JsfApplicationObjectConfigureListener>(
new JsfApplicationObjectConfigureListener());
}
static class JsfApplicationObjectConfigureListener extends ConfigureListener {
@Override
public void contextInitialized(ServletContextEvent sce) {
super.contextInitialized(sce);
ApplicationFactory factory = (ApplicationFactory) FactoryFinder
.getFactory(FactoryFinder.APPLICATION_FACTORY);
Application app = factory.getApplication();
app.addELResolver(new SpringBeanFacesELResolver());
}
}
}@Configuration
public class PortalServletConfiguration {
@Bean
public ServletRegistrationBean<FacesServlet> jsfServletRegistration(ServletContext servletContext) {
ServletRegistrationBean<FacesServlet> srb = new ServletRegistrationBean<FacesServlet>();
srb.setServlet(new FacesServlet());
srb.setUrlMappings(Arrays.asList("*.xhtml"));
srb.setLoadOnStartup(1);
return srb;
}

应用程序正在启动。但是，似乎没有一个JSF托管bean被初始化，因为我根本没有看到@PostContruct方法被调用。使用托管bean名称的所有EL引用(如#{} )都失败，错误如下
javax.faces.view.facelets.TagAttributeException Attribute did not evaluate to a String or Locale: null当我在@ManagedBean之上添加@Component到一个JSF托管bean时，这会导致@PostConstruct被调用，这可能意味着在我们以前的设置中，@ManagedBean类是由JSF加载的，但是在这个新的设置中，它们被忽略了。
有谁能帮我建议一下需要做些什么才能让它发挥作用？

根据注释修改配置类如下-
@SpringBootApplication(scanBasePackages = { "com.demo.spring.boot.jsfprimefaces", "com.ddd.efulfillment" })
@ImportResource({ "classpath:spring-root-config.xml", "classpath:spring-security-config.xml",
"classpath:spring-restclient-config.xml" })
public class JsfPrimefacesApplication extends SpringBootServletInitializer {
@Bean
public ServletContextInitializer servletContextInitializer() {
return servletContext -> {
//servletContext.addListener(com.sun.faces.config.ConfigureListener.class);
servletContext.setInitParameter("com.sun.faces.forceLoadConfiguration", Boolean.TRUE.toString());
// Set JSF/Primefaces init params
servletContext.setInitParameter("javax.faces.DEFAULT_SUFFIX", ".xhtml");
servletContext.setInitParameter("javax.faces.STATE_SAVING_METHOD", "client");
servletContext.setInitParameter("javax.faces.PROJECT_STAGE", "Production");
servletContext.setInitParameter("javax.faces.VALIDATE_EMPTY_FIELDS", "false");
servletContext.setInitParameter("javax.faces.FACELETS_SKIP_COMMENTS", "true");
// servletContext.setInitParameter("javax.faces.CONFIG_FILES",
// "/WEB-INF/faces-config.xml");
servletContext.setInitParameter("javax.faces.DATETIMECONVERTER_DEFAULT_TIMEZONE_IS_SYSTEM_TIMEZONE",
"true");
servletContext.setInitParameter("primefaces.THEME", "aristo");
servletContext.setInitParameter("primefaces.PUBLIC_CAPTCHA_KEY",
"ddd");
servletContext.setInitParameter("primefaces.PRIVATE_CAPTCHA_KEY",
"ssss");
servletContext.setInitParameter("primefaces.UPLOADER", "commons");
FacesInitializer facesInitializer = new FacesInitializer();
facesInitializer.onStartup(null, servletContext);
};
}
public static void main(String[] args) {
SpringApplication.run(JsfPrimefacesApplication.class, args);
}但同样的问题仍然存在。
在调试时，似乎托管bean在类com.sun.faces.config.processor.ManagedBeanConfigProcessor中通过方法"processAnnotations(ManagedBean.class);“进行标识。它有类似于下面的代码
FacesContext ctx = FacesContext.getCurrentInstance();
ApplicationAssociate associate =
ApplicationAssociate.getInstance(ctx.getExternalContext());
AnnotationManager manager = associate.getAnnotationManager();
manager.applyConfigAnnotations(ctx,
annotationType,
ConfigManager.getAnnotatedClasses(ctx).get(annotationType));我认为@ManagedBean注释类的映射是NULL。不知道为什么。

JSF2.2注释只有在具有这些注释的类显式提供给FacesInitializer之后才被识别，如下所示-
facesInitializer.onStartup(loadJSFAnnotatedClasses(package1...packageN),servletContext);
import com.google.common.collect.ImmutableMap;
import com.google.common.reflect.ClassPath;
private Set<Class<?>> loadJSFAnnotatedClasses(String... packageNames) {
Set<Class<?>> annotatedClasses = new HashSet<Class<?>>();
try {
for (String packageName : packageNames) {
annotatedClasses.addAll(ClassPath.from(ClassLoader.getSystemClassLoader()).getAllClasses().stream()
.filter(clazz -> clazz.getPackageName().equalsIgnoreCase(packageName))
.map(clazz -> clazz.load()).collect(Collectors.toSet()));
}
} catch (Exception e) {
return annotatedClasses;
}
return annotatedClasses;
