my first spring application我的一个Spring程序尝试

spring-framework-1.2.2+jdk1.5.004

1.directory
+My1stSpring
   --build.xml
   --hello.xml
   +lib
   +src
      +java
          --log4j.properties
          +hello
               --GreetingService.java
               --GreetingServiceImpl.java
               --HelloApp.java
      +webapp

2. source code
GreetingService.java

package hello;

public interface GreetingService
{
    public void sayGreeting();
}

GreetingServiceImpl.java

package hello;

public class GreetingServiceImpl implements GreetingService
{
    private String greeting;

    public GreetingServiceImpl(){}

    public GreetingServiceImpl(String greeting)
    {
        this.greeting=greeting;
    }

    public void sayGreeting()
    {
        System.out.println(greeting);
    }

    public void setGreeting(String greeting)
    {
        this.greeting=greeting;
    }
}

HelloApp.java

package hello;

import java.io.*;
import org.springframework.core.io.*;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;

public class HelloApp
{
    public static void main(String[] args) throws Exception
    {
        Resource res = new FileSystemResource("hello.xml");
        BeanFactory factory=new XmlBeanFactory(res);
        GreetingService greetingService=(GreetingService)factory.getBean("greetingService");
        greetingService.sayGreeting();
    }
}

3. mapping files fro spring
hello.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="greetingService" class="hello.GreetingServiceImpl">
        <property name="greeting">
            <value>Buenos Dias!</value>
        </property>
    </bean>
</beans>

4. build file for ant
build.xml

<project name="hello" default="init">
    <property name="spring.home" location="C:/java/spring-framework-1.2.2"/>
    <property name="target.dir" location="target"/>
    <property name="classes.dir" location="${target.dir}/classes"/>
    <property name="src.dir" location="src"/>
    <property name="java.src.dir" location="${src.dir}/java"/>
    <property name="webapp.src.dir" location="${src.dir}/webapp"/>
    <property name="app.lib.dir" location="lib"/>
    <property name="spring.lib.dir" location="${spring.home}/dist"/>
    <property name="spring.depends.dir" location="${spring.home}/lib"/>
    <property name="log.dir" location="logs"/>
    
    <path id="dependency.path">
        <fileset dir="${spring.lib.dir}" includes="*.jar"/>
        <fileset dir="${spring.depends.dir}" includes="**/*.jar"/>
        <fileset dir="${app.lib.dir}" includes="*.jar"/>
        <pathelement location="${classes.dir}"/>
    </path>
    
    <target name="init">
        <mkdir dir="${target.dir}"/>
    </target>
    
    <target name="build" depends="init">
        <mkdir dir="${classes.dir}"/>
        <javac destdir="${classes.dir}" classpathref="dependency.path">
            <src path="${java.src.dir}"/>
        </javac>
        <copy todir="${classes.dir}" > 
            <fileset dir="${java.src.dir}" >
                <exclude name="**/*.java"/> 
            </fileset> 
        </copy>
    </target>
    
    <target name="war" depends="build">
        <war destfile="${target.dir}/${ant.project.name}.war" webxml="${webapp.dir}/web.xml">
            <lib dir="${spring.lib.dir}"/>
            <lib dir="${app.lib.dir}"/>
            <classes dir="${classes.dir}"/>
        </war>
    </target>
    
    <target name="run" depends="build">  
        <java classpathref="dependency.path" classname="hello.HelloApp" fork="true" />
    </target> 
</project>

5. "ant build" to compile
    "ant run" to run the application!
