spring el在注解的形式

package com.h3.core;

import org.springframework.beans.factory.annotation.value;
import org.springframework.stereotype.component;

@component("customerbean")
public class customer {

	@value("#{'h3'.touppercase()}")
	private string name;

	@value("#{pricebean.getspecialprice()}")
	private double amount;

	public string getname() {
		return name;
	}

	public void setname(string name) {
		this.name = name;
	}

	public double getamount() {
		return amount;
	}

	public void setamount(double amount) {
		this.amount = amount;
	}

	@override
	public string tostring() {
		return "customer [name=" + name + ", amount=" + amount + "]";
	}

}

package com.h3.core;

import org.springframework.stereotype.component;

@component("pricebean")
public class price {

	public double getspecialprice() {
		return new double(199.09);
	}

}

输出

customer [name=h3, amount=199.09]

一点解释

@value("#{'h3'.touppercase()}")
private string name;

在 ‘pricebean‘ bean上调用getspecialprice() 方法

@value("#{pricebean.getspecialprice()}")
private double amount;

spring el在xml的形式

<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-3.0.xsd">
 
	<bean id="customerbean" class="com.h3.core.customer">
		<property name="name" value="#{'h3'.touppercase()}" />
		<property name="amount" value="#{pricebean.getspecialprice()}" />
	</bean>
 
	<bean id="pricebean" class="com.h3.core.price" />
	
</beans>

输出

customer [name=h3, amount=199.09]
