MinuteProject快速生成源码

　　MinuteProject是一个能够一次性生成源码的反转工程(reverse-engineering) 工具，也就是代码生成器，它能够产生各种开源堆栈的应用代码，后端根据已经存在数据表产生的代码包括： Hibernate, JPA, JPA2, springframework. REST: JEE-jersey, CXF, springMVC.等等；前端代码包括Openxava, Grails, Play. Methodology: FitNesse.还有: vaadin, jsf-primefaces, jooq, rails等

首先，下载MinuteProject，有命令和GUI两种方式启动：

1. 在解压后的项目/bin/start-console.cmd 或start-console.sh 启动GUI，如下图：

你可以选择你使用的数据库，目前支持下面几种：Oracle; DB2; Mysql; hsqldb; derby。

填写好数据库连接，比如mysql是：jdbc:mysql://127.0.0.1:3306/test，其中 test是你建立的数据库名称，输入用户名和密码，schema是已经存在的一个数据表，MinuteProject将根据这个表结构产生相应的模型和DAO代码。

roo package是指你的代码的包名，比如com.jdon，模型名称是你的业务模型名称，比如Order或Product等等。

下面可以选择target类型，也就是你需要生成代码的类型，有如下：

Maven Spring Hibernate (advanced DAO)
Maven Spring JPA/Hibernate (advanced DAO)
FitNesse
Spring/Hibernate (standard)
Spring/JPA/Hibernate (standard)
Spring/iBatis (standard)
OpenXava
Grails
Play
JPA2
JSF-primefaces
REST-JEE
WS-JEE

选择产生的代码类型后，点按generate，在项目目录output下生成了代码，如果你没有发现这个目录，主要可能是你的数据库参数没有配置正确。

2.命令行生成代码方式

在项目的/mywork/config目录下有一个样本配置文件：mp-config-sample.xml，根据你安装的数据库配置这个配置文件，存成另外一个文件如Hello.xml，里面的mysql配置如下：

<!DOCTYPE root>

<generator-config xmlns="http://minuteproject.sf.net/xsd/mp-config"

xmlns:xs="http://www.w3.org/2001/XMLSchema-instance"

xs:noNamespaceSchemaLocation="mp-config.xsd">

<data-model>

<driverClassName>org.gjt.mm.mysql.Driver</driverClassName>

<url>jdbc:mysql://localhost:3306/test</url>

</dataSource>

</primaryKeyPolicy>

</data-model>

<business-model>

<generation-condition>

</generation-condition>

<business-package default="model">

</business-package>

<!-- Enrichment gives extra information that can be used by the template

Ex: one concept such as indicating that an entity contains master data can trigger specific artifact generation on multiple level:

- specific DAO,

- cache configuration,

- presentation navigation behaviour (access to the entity via drop down list and not classical affection Sub Use Case)

- enumeration (strong typing) in some cases

- sql constraint statement in some cases

Enrichment can target entities, fields, business package

-->

</entity>

</enrichment>

</business-model>

</model>

</configuration>

</generator-config>

其中targets catalog-entry="JOOQ"是选择你生成代码的架构类型，这里是JOOQ。

在此目录下运行：

model-generation.cmd Hello.xml

那么在与当前config平行的目录/mywork/output下产生了代码。

例如testuser表产生的DAO接口TestuserDao代码如下：

public interface TestuserDao {

/**

* Inserts a Testuser entity

* @param Testuser testuser

public void insertTestuser(Testuser testuser) ;

/**

* Inserts a list of Testuser entity

* @param List<Testuser> testusers

public void insertTestusers(List<Testuser> testusers) ;

/**

* Updates a Testuser entity

* @param Testuser testuser

public Testuser updateTestuser(Testuser testuser) ;

/**

* Updates a Testuser entity with only the attributes set into Testuser.

* The primary keys are to be set for this method to operate.

* This is a performance friendly feature, which remove the udibiquous full load and full update when an

* update is to be done

* Remark: The primary keys cannot be update by this methods, nor are the attributes that must be set to null.

* @param Testuser testuser

public int updateNotNullOnlyTestuser(Testuser testuser) ;

public int updateNotNullOnlyPrototypeTestuser(Testuser testuser, Testuser prototypeCriteria);

/**

* Saves a Testuser entity

* @param Testuser testuser

public void saveTestuser(Testuser testuser);

/**

* Deletes a Testuser entity

* @param Testuser testuser

public void deleteTestuser(Testuser testuser) ;

/**

* @return Testuser The Testuser entity

public Testuser loadTestuser(Long id);

/**

* Testuser

* @param java.lang.String Userid

* @return Testuser The Testuser entity

public Testuser loadTestuser(java.lang.String userid);

/**

* @param List<java.lang.String> userids

* @return List<Testuser> The Testuser entity

public List<Testuser> loadTestuserListByTestuser (List<Testuser> testusers);

/**

* @param List<java.lang.String> userids

* @return List<Testuser> The Testuser entity

public List<Testuser> loadTestuserListByUserid(List<java.lang.String> userids);

/**

* Testuser and its dependent one to many objects

* @param Long id

* @return Testuser The Testuser entity

public Testuser loadFullFirstLevelTestuser(java.lang.String userid);

/**

* @param Testuser testuser

* @return Testuser The Testuser entity

public Testuser loadFullFirstLevelTestuser(Testuser testuser);

/**

public Testuser loadFullTestuser(Long id) ;

/**

* @param Testuser testuser

* @return List<Testuser>

public List<Testuser> searchPrototypeTestuser(Testuser testuser) ;

/**

* @param Testuser testuser

* @return List<Testuser>

public List<Testuser> searchPrototypeAnyTestuser(Testuser testuser) ;

public List<Testuser> find (Testuser testuser, EntityMatchType matchType, OperandType operandType, Boolean caseSensitivenessType) ;

/**

* @param List<Testuser> testusers

* @return List<Testuser>

public List<Testuser> searchPrototypeTestuser(List<Testuser> testusers) ;

/**

public List<Testuser> searchPrototypeTestuser(Testuser testuserPositive, Testuser testuserNegative) ;
