maven - tomcat上无法部署SpringRoo项目

Question

我开始使用以下环境开发一个新项目:

• Ubuntu 12.04
• java version "1.6.0_27"
• Eclipse Java EE IDE for Web Developers. Version: Helios Service Release 1
• SpringSource Tool Suite Version: 2.9.2.RELEASE
• tomcat 6 (which I can start, stop from Eclipse IDE)
• PostgresSql database + pgAdmin III

我遵循了预期的教程:

• docs.spring.io/spring-roo/reference/html/beginning.html
• docs.spring.io/spring-roo/reference/html/base-dbre.html

我设法创建了我的项目，并使用逆向工程过程生成了所有业务对象。 我还设法使用 Web MVC 进程创建了 Controller 对象。

我遇到的问题是我无法让我的项目在 tomcat 上运行。 我无法创建服务器并将我的项目添加到其中:我右键单击服务器选项卡，新建 => 新服务器 => 我选择 tomcat 6 => 我检查运行时环境:链接到/opt/tomcat6 并使用工作台默认 JRE 作为预期 => 我单击下一步按钮:然后我无法在列表中看到我的项目。所以我不能将它添加到服务器 为了尝试另一种方式，我将项目导出到位于/opt/tomcat6 中的 war 文件中。当我更新 war 文件时，我的应用程序似乎已在 webapps 上更新，但我认为 war 文件不正确，因为它的内容如下:

-- log.roo
-- pom.xml
-- .settings/
-- src/ And here
-- ++ main/
-- ++ ** java/
-- ++ ** resources/
-- ++ ** webapp/
-- ++ ** -- images/
-- ++ ** -- styles/
-- ++ ** -- WEB-INF/
-- ++ ** -- ++ classes/
-- ++ ** -- ++ i18n/
-- ++ ** -- ++ layouts/
-- ++ ** -- ++ spring/
-- ++ ** -- ++ tags/
-- ++ ** -- ++ views/
-- ++ ** -- ++ web.xml

当我访问我的本地主机:8080/MyProject/时，出现 404 错误……我认为根据目录内容这是预期的……？？？ ...

从网上搜索，我对 Project Facets 很感兴趣...我看到一个帖子，有人被告知要右键单击项目 => 配置 => 转换为分面形式...

只要“Convert to faceted form...”末尾有树点，我就点了这个菜单...居然把项目转换了-_-

我不知道这是一个额外的问题还是一件好事......但目前它并没有解决我的问题。

顺便说一句，我现在可以为我的项目选择构面......但是哪一个？？？那是另一个问题......

还有一条线索:

我看到在查看 Eclipse 的“问题”选项卡时出现 100 次相同的错误:

Description Resource Path Location Type
javax.servlet cannot be resolved to a type category.tagx /MyProject/src/main/webapp/WEB-INF/tags/menu line 1 JSP Problem

但是，我的 pom.xml 中有预期的以下内容:

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
    <scope>provided</scope>
</dependency>

在“错误日志”选项卡中，我也有以下错误(这应该与我的问题无关？): 错误 Project facet grails.app 尚未定义。它用于插件 com.springsource.sts.server.tc.core。

我也有这条消息(这肯定与我的问题有关？):

Info build: Abort due to missing classpath/inpath/aspectpath entries
Info /MyProject : Project 'MyProject' is missing required source folder: 'src/test/resources'
Info /MyProject : Project 'MyProject' is missing required source folder: 'src/test/java'

那些文件夹是存在的……但我没有使用它们，所以我从构建路径管理窗口的“源”选项卡中删除了它们。 它在“错误日志”选项卡中生成了很多错误。以下是一些可能对您有所帮助的示例:

• 现在“问题”选项卡中出现以下错误:

  描述资源路径位置类型 类路径错误:无法找到 org.aspectj.lang.JoinPoint(检查 aspectjrt.jar 是否在您的类路径中)MyProject 未知 Java 问题

但是，我的 pom.xml 中有预期的内容:

        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjrt</artifactId>
            <version>${aspectj.version}</version>
        </dependency>

Answer 1

这似乎是 Eclipse 的问题。尝试从头开始创建项目并使用 Maven Tomcat 插件运行:“mvn clean install tomcat:run”
