Spring Eclipse

Spring 3.1 + Eclipse 3.6

• eclipse 安裝套件

在Eclipse的套件中，安裝AJDT

eclipse->Help->install new software->add->輸入Name: ajdt
URL: http://download.eclipse.org/tools/ajdt/36/dev/update

其中36指的是Eclipse Helios版本,如果用的是3.4版，請改為34

安裝SpreingIDE

Name: SpringIDE
URL: http://dist.springframework.org/release/IDE

• 建立 Spring 專案

file -> new -> project -> Spring => Spring Project : myFirstSpring

• 匯入函式庫

  右鍵點選 myFirstSpring -> properties -> Java Build Path => Libraries => add External Jars
  

將　spring 資料夾內的jar 檔加入，<<重要>>　並且將　jakara-commons 的　logging.jar 匯入　（可使用hadoop/lib/ 內的　commons-*.jar）

• 建立佈署檔 beans-config.xml

右鍵點選 myFirstSpring -> new -> others -> XML => XML File -> myFirstSpring , File name = beans-config.xml

• beans-config.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="helloBean" 
    class="onlyfun.caterpillar.HelloBean"> 
        <property name="helloWord">
            <value>Hello! Waue!</value>
        </property> 
    </bean> 
</beans>

• src/waue.org/HelloBean.java

package waue.org; 

public class HelloBean { 
    private String helloWord; 
    
    public void setHelloWord(String helloWord) { 
        this.helloWord = helloWord; 
    } 
    public String getHelloWord() { 
        return helloWord; 
    } 
}

• src/waue.org/SpringDemo.java

package waue.org;

import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.FileSystemResource;
import org.springframework.core.io.Resource;

public class SpringDemo { 
    public static void main(String[] args) { 
        Resource rs = 
            new FileSystemResource("beans-config.xml"); 
        BeanFactory factory = 
            new XmlBeanFactory(rs); 
        
        HelloBean hello = 
            (HelloBean) factory.getBean("helloBean"); 
        System.out.println(hello.getHelloWord()); 
    } 
}

• 看結果

run -> "run aspectj/java application" or "run java application" 皆可
