appfuse2.02 使用教程(一)

安装、配置好appfuse后，按一下步骤使用：

1 创建项目(更多建项命令请到官方查看)

mvn archetype:create -DarchetypeGroupId=org.appfuse.archetypes -DarchetypeArtifactId=appfuse-basic-struts -DremoteRepositories=http://static.appfuse.org/releases -DarchetypeVersion=2.0.2 -DgroupId=com.mycompany1.app -DartifactId=myproject1

2 运行项目

 如果mysql的root用户有口令，在pom.xml文件设置口令。如下：
        <jdbc.username>root</jdbc.username>
        <jdbc.password>123456</jdbc.password>


进入项目所在目录，运行以下命令：

mvn jetty:run-war

打开浏览器上，从以下连接进入： http://localhost:8080


3  将appfuse的源码装入项目

执行以下命令，将appfuse的源码装入项目的源码装入项目。

mvn appfuse:full-source

这个命令完成以下功能:
1.  将dao 、service、web的基础代码装入项目.
2.  将这些类的包名改为项目自己的包名.


4  代码生成

 AMP(The AppFuse Maven Plugin) plugin currently does two things:
 1) code generation for CRUD and
 2) allows you to convert your project to use AppFuse's source instead of using its binary dependencies.

4.1 Generating CRUD with AMP

4.1.1  生成pojo类

首先，创建表：

 CREATE TABLE `Mmployee` (
`id` bigint(20) NOT NULL auto_increment,
`code` varchar(10) NOT NULL,
`dept` varchar(50) NOT NULL,
`name` varchar(20) NOT NULL,
`status` varchar(10) NOT NULL,
`telephone` varchar(20) default NULL,
`title` varchar(50) NOT NULL,
PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
                          
There's also a goal that allows you to generate model objects from database tables.

mvn appfuse:gen-model

提示如下：
E:\DevelopSrc\myproject1>mvn appfuse:gen-model

This goal will install the generated files into your source tree, unless you specify
-DdisableInstallation=true. After running this command, you can use appfuse:gen to generate
CRUD classes/tests/screens for this object.
 
4.1.2  生成基本的 dao、service、struts代码

You can run the following command to generate CRUD screens/classes for a POJO:

mvn appfuse:gen -Dentity=Name

If you don't specify the entity name, you will be prompted for it. Currently, if a @Column has "nullable =
false", a "required field" validation rule will be generated as part of the web framework's validation
configuration. This command will also install the generated code, unless you specify
-DdisableInstallation=true.
If your entity is not defined in hibernate.cfg.xml, it will be added.

In a modular project, these commands must be run in the "core" and "web" modules. The plugin is smart
enough to figure out when it should/should not generate stuff based on the packaging type (jar vs. war).
If you want to generate specific code in a "war" project, you can use gen-core or gen-web.


接前一步，执行：

 mvn appfuse:gen -Dentity=Employee

提示如下：
E:\DevelopSrc\myproject1>mvn appfuse:gen

出了错误。查看原代码，原来model中有两个ID的生成策略，如下：

  @Id @GeneratedValue(strategy=IDENTITY) @GeneratedValue(strategy = GenerationType.AUTO)

删除@GeneratedValue(strategy=IDENTITY)，只剩下一个。

再执行 mvn appfuse:gen -Dentity＝Employee。
失败，出现以下错误提示：

原因：
上面的问题有两个：
1 org.xml.sax.SAXNotRecognizedException：
  是因为jdk的问题，jdk5不会出现这问题。
2 java.lang.IllegalArgumentException：
  是ant的bug，路径里面不能有空格，因为Documents and Settings里面有空格所以报错。
直接把repository文件夹拷贝到 E:\AppfuseEnv\repository。
然后，在E:\AppfuseEnv\Tools\apache-maven-2.0.9\conf的settings.xml修改如下：

!-- localRepository
   | The path to the local repository maven will use to store artifacts.
   |
   | Default: ~/.m2/repository
<localRepository>/path/to/local/repo</localRepository>
-->
<localRepository>E:\AppfuseEnv\repository</localRepository>

搞定,但是，
注意：如果你希望appfuses生成 dao 和 service 类，就在项目根目录下的pom.xml中，把genericCore属性设为false。

        <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>appfuse-maven-plugin</artifactId>
                <version>${appfuse.version}</version>
                <configuration>
                    <genericCore>${amp.genericCore}</genericCore>
                    <fullSource>${amp.fullSource}</fullSource>
                </configuration>
            </plugin>
 如果 DAOs and Managers 不是使用基础公用类（也就是GenericManagerImpl或者UniversalManagerImpl），那么amp.genericCore 的属性值设置为false。这样会生成单独的DAOs and Managers类，以方便加入代码。否则设置为true。
 如果已经执行过 mvn appfuse:full-source 命令，则 amp.fullSource 的属性值设置 true。它会将你的代码中的“org.appfuse”包名前缀修改为你自己的包名。




4.1.3  Removing Code

You can run mvn appfuse:remove to remove the artifacts installed by appfuse:gen.

5 定制模板

If you want to customize the code generation templates (written in FreeMarker), you can copy them into
your project using the following command:

mvn appfuse:copy-templates
