步骤:
第一步:建工程
File -> New -> Project ->Web Project,"Project Name":MySpringTest,然后"Finish";
第二步:导入spring包
选中MySpringTest,右击,MyEclipse -> Add Spring Capabilities……,都默认即可;
第三步:
建立项目所需类;MySpringTest -> src -> New ...(以下三个都这样建)Spring 的开发没法自动生成 Bean, 这里大家只好手工来写了, 也很简单。
1、接口Action:(MySpringTest -> src -> New -> interface ,取名为Action)
public interface Action {
public String execute(String str);
}
2、实现接口Action的类UpperAction:(将其 message 属性与输入字符串相连接,并返回其大写形式。)
(MySpringTest -> src -> New -> class ,取名为UpperAction)
public class UpperAction implements Action {
private String message;
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public String execute(String str) {
return (getMessage() + str).toUpperCase();
}
}
3、实现接口Action的类LowerAction:
(将其 message 属性与输入字符串相连接,并返回其小写形式。)
(MySpringTest -> src -> New -> class ,取名为LowerAction)
public class LowerAction implements Action {
private String message;
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public String execute(String str) {
return (getMessage() + str).toLowerCase();
}
}
4、做测试用的SimpleTest类:
(MySpringTest -> src -> New -> class ,取名为SimpleTest)
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
public class SimpleTest {
public static void main(String args[]) {
SimpleTest test = new SimpleTest();
test.testQuickStart();
}
public void testQuickStart() {
ApplicationContext ctx = new FileSystemXmlApplicationContext(
"src/applicationContext.xml");
Action action = (Action) ctx.getBean("action1");
System.out.println(action.execute("Rod Johnson"));
action = (Action) ctx.getBean("action2");
System.out.println(action.execute("jeckj"));
}
}
5、配置applicationContext.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
<description>Spring Quick Start</description>
<!--该处bean中的name值必须是 其对应的class中的私有成员名
-->
<bean id="action1" class="UpperAction">
<property name="message">
<value>HeLLo</value>
</property>
</bean>
<bean id="action2" class="LowerAction">
<property name="message">
<value>HeLLo</value>
</property>
</bean>
</beans>
5、在WEB-INF/class 目录下建立一个log4j.propertie
log4j.rootLogger=ERROR,stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %5p (%F:%L) - %m%n
第四步:调试
双击 Package Explorer 下 MySpringTest/src/TestAction.java 打开源代码,点击菜单 Run -> Run As -> 1. Java Application, 如果没有错误的话将会出现如下
HELLOROD JOHNSON
