joeyta備忘記: MyEclipse - JSF Spring Hibernate備忘記

這次主要使用MyEclpse對Spring Hibernate JSF作簡單的備忘過程,

首先自行安裝 jdk, tomcat, mysql, eclipse.
http://java.sun.com/j2se/1.5.0/download.jsp
http://jakarta.apache.org/site/downloads/downloads_tomcat-5.html
http://dev.mysql.com/downloads/mysql/5.0.html
http://www.eclipse.org/downloads/

在Mysql建立資料庫及表格:
DB user: root password: rootpassword
create database mysurvey;
create table survey(
id int(10) not null auto_increment,
name varchar(50) not null,
email varchar(30) not null,
result varchar(1) not null,
primary key(id)
);

安裝MyEclipse:
http://www.myeclipseide.com/ContentExpress-display-ceid-10.html

安裝Eclipse Property File GUI Editor:
http://sourceforge.net/project/showfiles.php?group_id=117908

建立Web project:
File -> New -> project ->> MyEclipse -> J2EE Project -> Web Project ->> Next
輸入Project Name : MySurvey -> Finish
建主package ( 方便日後便用MyEclipse Database generate Persistant Bean ):
選MySurvey -> src -> New -> Package ->>
Name : com.joeyta.mysurvey -> Finish

然後download mysql jdbc driver 放在 MySurvey -> WebRoot -> WEB-INF -> lib :
http://dev.mysql.com/downloads/connector/j/3.1.html

建立 DB Profile (方便日後Hibernate使用及 Generate Beans):
Window -> Open Perspective -> other ->> MyEclipse Database Explorer
DB Browser View -> New
Profile name: mysurvey
Driver: MMMySQL Driver
URL: jdbc:mysql://localhost:3306/mysurvey ( 在Mysql裡要先建立mysurvey database )
User name: root
Password: rootpassword
Open on Eclipse startup: unchecked
Prompt for password: unchecked
-> Next
Display the selected schemas: checked
按 Add -> check mysurvey -> Finish

Generates Persistants Beans:
DB Browser View -> mysurvey -> Open Connection
->> Connected to mysurvey ->mysurvey -> TABLE -> survey
->> Create Hibernate Mapping
Java src folder: /MySurvey/src
java package: com.joeyta.mysurvey
Update hibernate configuration with mapping file location
-> Finish
打開 Package Explorer -> MySurvey -> src -> com.joeyta.mysurvey
就會看到兩個java ( AbstractSurvey.java, Survey.java ) 及 1個mapping file ( Survey.hbm.xml ).
並將mapping file update 到 Hibernate.cfg.xml
( 平時玩Hibernate,通常玩的是mapping files -> beans 及 mapping files -> table scrip,很少玩tablescript > beans )

修改 Survey.hbm.xml :
由於generate 出來的Survey.hbm.xml 裡 class 裡多了catalog property,這會影響SQL.
在<generator class="assigned" /> 這個不是我會想要的,由於mysql中的id是auto_increment,故需要改成native

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
<class name="com.joeyta.mysurvey.Survey" table="survey">
<id name="id" type="integer">
<column name="id" />
<generator class="native" />
</id>
<property name="name" type="string">
<column name="name" length="50" not-null="true" />
</property>
<property name="email" type="string">
<column name="email" length="30" not-null="true" />
</property>
<property name="result" type="string">
<column name="result" length="1" not-null="true" />
</property>
</class>
</hibernate-mapping>

加入 JSF Capabilities:
點選 MySurvey -> MyEclipse -> Add JSF Capabilities
JSF Implementation : MyFaces 1.1.1 -> Finish
有點奇怪的是有些library沒有把它加到WEB-INF/lib裡,
尤其是以下這三個,
jsf-api.jar, jsf-impl.jar, standard.jar
可以到MyEclipse library folder找出來或到
http://java.sun.com/javaee/javaserverfaces/

加入 Hibernate Capabilities:
點選 MySurvey -> MyEclipse -> Add Hibernate Capabilities
Hibernate Specification: Hibernate 3
JAR Library Installation: Copy checked Library Jars to project folder and add to build-path
-> Next
Hibernate config file: New
-> Next
Specify database connection details?: checked
DataSource: Use JDBC Driver
DB Profile: mysurvey ( 這裡就是剛剛建立的DB Profile )
-> Next
Create SessionFactory class: unchecked -> Finish

hibernate.cfg.xml :

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

<session-factory>
<property name="connection.username">root</property>
<property name="connection.url">jdbc:mysql://localhost:3306/mysurvey</property>
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="myeclipse.connection.profile">mysurvey</property>
<property name="connection.password">rootpassword</property>
<property name="connection.driver_class">org.gjt.mm.mysql.Driver</property>
<mapping resource="com/joeyta/mysurvey/Survey.hbm.xml"></mapping>

</session-factory>

</hibernate-configuration>

加入 Spring Capabilities:
點選 MySurvey -> MyEclipse -> Add Spring Capabilities
Show MyEclipse Libraries : checked
並選下面這些 libraries:
Spring 1.2 AOP Libraries
Spring 1.2 Core Libraries
Spring 1.2 ORM/DAO/Hibernate3 Libraries
spring 1.2 Web Libraries
Jar Library Installation: Copy checked Library contents to project folder
Library Folder: /WebRoot/WEB-INF/lib
-> Next
Specify new or existing Spring bean configuration file? checked
-> Next
Create Spring LocalSessionFactory that references the hibernate config using a configLocation property? checked
Spring Config: src/applicationContext.xml
SessionFactory id: sessionFactory
-> Finish

建立log4j.properties:
MySurvey -> src -> New -> File
File name: log4j.properties
############# log4j.properties #############
# Set root logger level to DEBUG and its only appender to A1.
log4j.rootLogger=INFO, A1

# A1 is set to be a ConsoleAppender.
log4j.appender.A1=org.apache.log4j.ConsoleAppender

# A1 uses PatternLayout.
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

com.mchange.v2.log.MLog=com.mchange.v2.log.log4j.Log4jMLog
log4j.logger.mo.org.cpttm.workflow=INFO
############# log4j.properties #############

建立DAO object :
( 日後利用Spring AOP, JSF就能存取DAO Object,
這裡為求簡便,不打算利用Spring AOP處理Transaction )
/*********** ISurveyDAO.java **********/
package com.joeyta.mysurvey;
public interface ISurveyDAO {
public void insert(Survey survey);
public Survey find(Integer id);
public boolean isExist(String name, String email);
}
/*********** ISurveyDAO.java **********/

/*********** SurveyDAO.java **********/
package com.joeyta.mysurvey;
import java.util.List;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
public class SurveyDAO extends HibernateDaoSupport implements
ISurveyDAO {

public SurveyDAO() {
super();
}

public void insert(Survey survey) {
getHibernateTemplate().save(survey);
}

public Survey find(Integer id) {
Survey survey = (Survey) getHibernateTemplate()
.get(Survey.class, id);
return survey;
}

public boolean isExist(String name, String email) {
List list = getHibernateTemplate().find(
"from survey s where s.name='"+name+"' or s.email='"+email+"'");
return list.size() > 0;
}

}
/*********** SurveyDAO.java **********/

修改 applicationContext.xml :

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocation">
<value>/WEB-INF/classes/hibernate.cfg.xml</value>
</property>
</bean>
<bean id="surveyDAO" class="com.joeyta.mysurvey.SurveyDAO">
<property name="sessionFactory">
<ref bean="sessionFactory"/>
</property>
</bean>
</beans>

修改 Survey.java :
/********************* Survey ************************************/
package com.joeyta.mysurvey;

import javax.faces.context.FacesContext;
import javax.faces.event.ValueChangeEvent;

public class Survey extends AbstractSurvey implements java.io.Serializable {
private static final long serialVersionUID = -6603171231966815078L;

public Survey() {
}

public Survey(Integer id, String name, String email, String result) {
super(id, name, email, result);
}

private String locale = "zh_TW";

private String message;

private SurveyDAO surveyDAO;

public String getParameter(String name, String sDefaultValue) {
if (FacesContext.getCurrentInstance().getExternalContext()
.getRequestParameterMap().get(name) != null) {
return (String) FacesContext.getCurrentInstance()
.getExternalContext().getRequestParameterMap().get(name);
}
return sDefaultValue;
}

public String submit() {
if (surveyDAO.isExist(getName(), getEmail())) {
setMessage("每位會員只能參加一次!");
return "failure";
} else {
setMessage("多謝閣下參與!");
this.surveyDAO.insert(this);
return "success";
}
}

public void changeLocale(ValueChangeEvent event) {
if (locale.equals("zh_TW"))
locale = "zh_CN";
else
locale = "zh_TW";
}

public String getLocale() {
return locale;
}

public void setLocale(String locale) {
this.locale = locale;
}

public String getMessage() {
return message;
}

public void setMessage(String message) {
this.message = message;
}

public SurveyDAO getSurveyDAO() {
return surveyDAO;
}

public void setSurveyDAO(SurveyDAO surveyDAO) {
this.surveyDAO = surveyDAO;
}
}

/********************* Survey ************************************/

建立messages.properties:
MySurvey -> src -> New -> File
File name: messages.properties
Right click messages.properties -> Open With -> Property File GUI Editor
( 由於剛剛將了Property File GUI Editor )
打開後按 Add locale
Local: zh_TW -> OK
再按 Add locale
Local: zh_CN -> OK
儲存後就會看到多出兩個檔案 messages_zh_TW.properties 及 messages_zh_CN.properties
其實這三個檔案就會出來國際化訊息使用,即支持繁簡體.
