Spring

Spring Bean AOP XML junit

SomeBean.java

java 代码

package com.gjx.spring;
//测试Spring的继承
public class SomeBean {
private String name;
private int age;
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}

somebean-config.xml

xml 代码

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">
<bean id="inheritedSomeBean" abstract="true">
<property name="name">
<value>冬国</value>
</property>
<property name="age">
<value>22</value>
</property>
</bean>
<bean id="some" class="com.gjx.spring.SomeBean" parent="inheritedSomeBean">
<property name="name">
<value>完全抽象的继承</value>
</property>
</bean>
<bean id="beanInstance" class="com.gjx.spring.SomeBean">
<property name="name">
<value>冬国</value>
</property>
<property name="age">
<value>30</value>
</property>
</bean>
<bean id="instanceSome" class="com.gjx.spring.SomeBean" parent="beanInstance">
<property name="name">
<value>实例来继承</value>
</property>
</bean>
</beans>

测试类：

java 代码

package Test.com.gjx.spring;
import junit.framework.TestCase;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;
import com.gjx.spring.HelloBean;
import com.gjx.spring.SomeBean;
public class TestHelloBean extends TestCase {
　　　　//测试继承
public void testSomeBean(){
ApplicationContext context=new ClassPathXmlApplicationContext("somebean-config.xml");
SomeBean some=(SomeBean)context.getBean("some");
SomeBean instanceSome=(SomeBean)context.getBean("instanceSome");
System.out.println("Abstract>>> name="+some.getName()+" age="+some.getAge());
System.out.println("Instance>>> name="+instanceSome.getName()+" age="+instanceSome.getAge());
}
}

测试结果：

冬国
Abstract>>> name=完全抽象的继承 age=22
Instance>>> name=实例来继承 age=30

<bean id="baseController" class="com.supcon.electronic.its.controller.BaseController" abstract="true">
<property name="operationservice" ref="operationService" />
</bean>

<bean class="com.supcon.electronic.its.controller.MenuController">
<property name="userService" ref="userService" />
</bean>

=====================================================
GOOD. 受启发, 现在所有共通的Service都配置到BaseController里
JAVA上.普通Controller继承BaseController.
大大减少了普通Controller的Service属性及方法,更减少了配置XML.
另一点.一些共通的方法也可以写到BaseController里了.
解决了没有"父亲"的GANGA
