xml配置不变,如下
<?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-2.0.xsd">
<bean id="test3" class="org.springframework.tests.sample.beans.TestBean" scope="prototype">
<property name="name"><value>custom</value></property>
<property name="age"><value>25</value></property>
</bean>
</beans>
3.0版之前
获取bean的方式是用 XmlBeanFactory
@Test
public void beanTest(){
Resource rs2 = new ClassPathResource("test.xml",AATest.class);
BeanFactory bf = new XmlBeanFactory(rs2);
TestBean tb2 = (TestBean)bf.getBean("test3");
assertEquals("custom",tb2.getName());
}
3.1版本之后,因为某些原因,XmlBeanFactory被抛弃了,如果再用的化,会显示
The type XmlBeanFactory is deprecated
源码里的测试方法里获取bean的方法如下
@Test
public void beanTest2(){
Resource rs = new ClassPathResource("test.xml",AATest.class);;
DefaultListableBeanFactory grandParent = new DefaultListableBeanFactory();
new XmlBeanDefinitionReader(grandParent).loadBeanDefinitions(rs);
TestBean tb = (TestBean) grandParent.getBean("test3");
assertEquals("custom",tb.getName());
}
至于被抛弃的原因,如下
/**
* Convenience extension of {@link DefaultListableBeanFactory} that reads bean definitions
* from an XML document. Delegates to {@link XmlBeanDefinitionReader} underneath; effectively
* equivalent to using an XmlBeanDefinitionReader with a DefaultListableBeanFactory.
*
* <p>The structure, element and attribute names of the required XML document
* are hard-coded in this class. (Of course a transform could be run if necessary
* to produce this format). "beans" doesn‘t need to be the root element of the XML
* document: This class will parse all bean definition elements in the XML file.
*
* <p>This class registers each bean definition with the {@link DefaultListableBeanFactory}
* superclass, and relies on the latter‘s implementation of the {@link BeanFactory} interface.
* It supports singletons, prototypes, and references to either of these kinds of bean.
* See {@code "spring-beans-3.x.xsd"} (or historically, {@code "spring-beans-2.0.dtd"}) for
* details on options and configuration style.
*
* <p><b>For advanced needs, consider using a {@link DefaultListableBeanFactory} with
* an {@link XmlBeanDefinitionReader}.</b> The latter allows for reading from multiple XML
* resources and is highly configurable in its actual XML parsing behavior.
