java - 将 Spring Roo 与 JSF 2.0 + Primefaces 结合使用时出现的问题

Question

我找到了this DZone 上的精彩帖子:

我想尝试一下。 我一步一步地遵循这个例子，它对我来说非常有效。不到 5 分钟，我就启动并运行了该 Web 应用程序。

我决定创建自己的应用程序只是为了好玩。但它不起作用，我也不知道为什么会这样。我确信我以完全相同的方式做了每件事，但只是使用我自己的变量名。 这是我所做的每一件事:

1- 从我的 Linux 终端创建一个文件夹并导航到它

mkdir whatsup
cd whatsup

2- 我启动了 roo shell 开始工作(我的 ROO_HOME 配置正确)

/roo.sh

/_/ |_|\____/\____/    1.2.1.RELEASE [rev 6eae723]


Welcome to Spring Roo. For assistance press TAB or type "hint" then hit ENTER.

3-我创建了项目定义

roo> project --topLevelPackage com.hack --projectName whats-up

Created ROOT/pom.xml
Created SRC_MAIN_RESOURCES
Created SRC_MAIN_RESOURCES/log4j.properties
Created SPRING_CONFIG_ROOT
Created SPRING_CONFIG_ROOT/applicationContext.xml

4-我启用了持久层

roo> persistence setup --provider HIBERNATE --database HYPERSONIC_IN_MEMORY

Created SPRING_CONFIG_ROOT/database.properties Updated SPRING_CONFIG_ROOT/applicationContext.xml Created SRC_MAIN_RESOURCES/META-INF/persistence.xml Updated ROOT/pom.xml [added dependencies org.hsqldb:hsqldb:1.8.0.10, org.hibernate:hibernate-core:3.6.9.Final, org.hibernate:hibernate-entitymanager:3.6.9.Final, org.hibernate.javax.persistence:hibernate-jpa-2.0-api:1.0.1.Final, org.hibernate:hibernate-validator:4.2.0.Final, javax.validation:validation-api:1.0.0.GA, cglib:cglib-nodep:2.2.2, javax.transaction:jta:1.1, org.springframework:spring-jdbc:${spring.version}, org.springframework:spring-orm:${spring.version}, commons-pool:commons-pool:1.5.6, commons-dbcp:commons-dbcp:1.3]

5-我创建了我的第一个实体

roo> entity jpa --class ~.domain.Message

Created SRC_MAIN_JAVA/com/hack/domain Created SRC_MAIN_JAVA/com/hack/domain/Message.java Created SRC_MAIN_JAVA/com/hack/domain/Message_Roo_Configurable.aj Created SRC_MAIN_JAVA/com/hack/domain/Message_Roo_ToString.aj Created SRC_MAIN_JAVA/com/hack/domain/Message_Roo_Jpa_ActiveRecord.aj Created SRC_MAIN_JAVA/com/hack/domain/Message_Roo_Jpa_Entity.aj

6-我将字段添加到实体

~.domain.Message roo> field number --fieldName votes --type java.lang.Integer --notNull

Updated SRC_MAIN_JAVA/com/hack/domain/Message.java Created SRC_MAIN_JAVA/com/hack/domain/Message_Roo_JavaBean.aj

7- 将 Web 层包含到我的项目中

~.domain.Message roo> web jsf setup --implementation APACHE_MYFACES --theme PEPPER_GRINDER

Created ROOT/src/main/webapp Created ROOT/src/main/webapp/index.html Created ROOT/src/main/webapp/viewExpired.xhtml Created ROOT/src/main/webapp/resources/images Created ROOT/src/main/webapp/resources/images/csv.png
Created com.hack.jsf.converter.MessageConverter Created ROOT/src/main/webapp/resources/images/de.png Created ROOT/src/main/webapp/resources/images/en.png Created ROOT/src/main/webapp/resources/images/es.png Created ROOT/src/main/webapp/resources/images/excel.png Created ROOT/src/main/webapp/resources/images/favicon.ico Created ROOT/src/main/webapp/resources/images/pdf.png Created ROOT/src/main/webapp/resources/images/roo_logo.png Created ROOT/src/main/webapp/resources/images/springsource-logo.png Created ROOT/src/main/webapp/resources/images/xml.png Created ROOT/src/main/webapp/resources/css Created ROOT/src/main/webapp/resources/css/standard.css Created ROOT/src/main/webapp/resources/js Created ROOT/src/main/webapp/resources/js/calendar.js Created ROOT/src/main/webapp/templates Created ROOT/src/main/webapp/templates/content.xhtml Created ROOT/src/main/webapp/templates/footer.xhtml Created ROOT/src/main/webapp/templates/header.xhtml Created ROOT/src/main/webapp/templates/layout.xhtml Created ROOT/src/main/webapp/templates/menu.xhtml Created ROOT/src/main/webapp/pages Created ROOT/src/main/webapp/pages/main.xhtml Updated ROOT/pom.xml [added dependencies org.apache.myfaces.core:myfaces-api:2.1.5, org.apache.myfaces.core:myfaces-impl:2.1.5, org.primefaces:primefaces:3.1, org.primefaces.themes:south-street:1.0.3, org.springframework:spring-web:${spring.version}, javax.el:el-api:2.2, commons-fileupload:commons-fileupload:1.2.2, commons-io:commons-io:2.1; added repository http://repository.primefaces.org; added dependency org.primefaces.themes:pepper-grinder:1.0.3; updated project type to war] Created SRC_MAIN_WEBAPP/WEB-INF Created SRC_MAIN_WEBAPP/WEB-INF/web.xml

8-我执行了一个包

~.domain.Message roo> web jsf all --package ~.jsf

Created ROOT/src/main/resources/com/hack/jsf/i18n Created ROOT/src/main/resources/com/hack/jsf/i18n/messages_de.properties Created ROOT/src/main/resources/com/hack/jsf/i18n/messages_en.properties Created ROOT/src/main/resources/com/hack/jsf/i18n/messages_es.properties Created SRC_MAIN_JAVA/com/hack/jsf Created SRC_MAIN_JAVA/com/hack/jsf/MessageBean.java Created SRC_MAIN_JAVA/com/hack/jsf/converter Created SRC_MAIN_JAVA/com/hack/jsf/converter/MessageConverter.java Created SRC_MAIN_WEBAPP/WEB-INF/faces-config.xml Created SRC_MAIN_JAVA/com/hack/jsf/ApplicationBean.java Created SRC_MAIN_JAVA/com/hack/jsf/util Created SRC_MAIN_JAVA/com/hack/jsf/util/LocaleBean.java Created SRC_MAIN_JAVA/com/hack/jsf/util/ViewExpiredExceptionExceptionHandlerFactory.java Created SRC_MAIN_JAVA/com/hack/jsf/util/ViewExpiredExceptionExceptionHandler.java Created SRC_MAIN_WEBAPP/pages/message.xhtml Created SRC_MAIN_JAVA/com/hack/jsf/ApplicationBean_Roo_ApplicationBean.aj Created SRC_MAIN_JAVA/com/hack/jsf/ApplicationBean_Roo_Configurable.aj Created SRC_MAIN_JAVA/com/hack/jsf/converter/MessageConverter_Roo_Converter.aj Created SRC_MAIN_JAVA/com/hack/jsf/converter/MessageConverter_Roo_Configurable.aj Created SRC_MAIN_JAVA/com/hack/jsf/MessageBean_Roo_Serializable.aj Created SRC_MAIN_JAVA/com/hack/jsf/MessageBean_Roo_Configurable.aj Created SRC_MAIN_JAVA/com/hack/jsf/MessageBean_Roo_ManagedBean.aj

9-退出 roo shell

~.jsf roo> quit

10- 在 Linux 终端，从项目内部我确实运行了教程中建议的命令以在 tomcat 7 中执行

~/hackday/whatsup$ mvn package org.codehaus.cargo:cargo-maven2-plugin:run -Dcargo.maven.containerId=tomcat7x -Dcargo.maven.containerUrl=http://archive.apache.org/dist/tomcat/tomcat-7/v7.0.22/bin/apache-tomcat-7.0.22.zip

这是尝试运行时的输出:

我不知道如何让它发挥作用。 正如你所看到的，我的步骤与 DZone 教程完全相同，我不知道有什么不同。 有趣的是，他们的示例有效，但我的示例无效。

我也尝试过但没有运气: mvn 全新安装 这将使我构建成功，但无法使其在服务器上运行 mvn tomcat:运行 与其他命令的结果相同

如果有人有使用 Spring Roo 与 JSF 结合使用的经验，我很感激一些帮助。

Answer 1

看起来“Message”与自动生成的代码使用的某些名称冲突。您会尝试使用“MyMessage”吗？
