Spring入门实例-bean初始化

Spring入门实例 bean的初始化

实例：

bean类：

public static DatabaseXMLBean createInstanceother()
	{
		DatabaseXMLBean bean = new DatabaseXMLBean();
		bean.setName("emp");
		bean.setLength(10);
		return bean;
	}
	private String name;
	public String getName()
	{

		System.out.println("！！！！！！！！！！！！！！！！！！！！DataBaseXML,getname");
		return name;
	}
	public void setName(String name)
	{
		System.out.println("！！！！！！！！！！！！！！！！！！！！DataBaseXML,setname");
		this.name = name;
	}
	public String getType()
	{
		System.out.println("！！！！！！！！！！！！！！！！！！！！DataBaseXML,gettype");
		return type;
	}
	public void setType(String type)
	{
		System.out.println("！！！！！！！！！！！！！！！！！！！！DataBaseXML,settype");
		this.type = type;
	}
	public int getLength()
	{
		System.out.println("！！！！！！！！！！！！！！！！！！！！DataBaseXML,getlength");
		return length;
	}
	public void setLength(int length)
	{
		System.out.println("！！！！！！！！！！！！！！！！！！！！DataBaseXML,setlength");
		this.length = length;
	}
	public String getJdbcName()
	{
		return jdbcName;
	}
	public void setJdbcName(String jdbcName)
	{
		this.jdbcName = jdbcName;
	}
	public String getJdbcType()
	{
		return jdbcType;
	}
	public void setJdbcType(String jdbcType)
	{
		this.jdbcType = jdbcType;
	}
	public boolean isPrimaryKey()
	{
		return primaryKey;
	}
	public void setPrimaryKey(boolean primaryKey)
	{
		this.primaryKey = primaryKey;
	}
	public boolean isVisible()
	{
		return visible;
	}
	public void setVisible(boolean visible)
	{
		this.visible = visible;
	}
	private String type;
	private int length;
	private String jdbcName;
	private String jdbcType;
	private boolean primaryKey;
	private boolean visible;

	@Override
	public String toString()
	{
		StringBuffer sb = new StringBuffer();
		sb.append("type:").append(type).append("\n");
		sb.append("length:").append(length).append("\n");
		sb.append("jdbcName:").append(jdbcName).append("\n");
		sb.append("jdbcType:").append(jdbcType).append("\n");
		sb.append("primaryKey:").append(primaryKey).append("\n");
		sb.append("visible:").append(visible);
		return sb.toString();
	}
	
	public void init() throws Exception{
		System.out.println("DataBaseXML,init方法初始化");
	}
	
	public DatabaseXMLBean()
	{
		System.out.println("DataBaseXML构造函数");
	}

 配置文件：

<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">

	<bean name="column2" class="com.myspring.MyJavaBean" init-method="init">
		<property name="name" value="dirk.zhang"></property>
	</bean>
	
	<bean name="column3" class="com.myspring.DatabaseXMLBean" init-method="init">
		<property name="type" value="String"></property>
		<property name="length" value="0"></property>
	</bean>
	
	<bean name="column4" class="com.myspring.MytestSpring" init-method="init">
	</bean>

</beans>

 测试方法：

System.out.println("加载Spring配置文件");
//		Resource res = new ClassPathResource("com/myspring/demo-bean.xml");//spring url require the src as initsource
//		BeanFactory factory = new XmlBeanFactory(res);
		ApplicationContext context = new ClassPathXmlApplicationContext("com/myspring/DatabaseXMLBean.xml");
		BeanFactory xmlbf = context;//ApplicationContext可以转换为Beanfactory
		System.out.println("加载spring配置文件结束");
		MyJavaBean bean = (MyJavaBean) context.getBean("column2");
		System.out.println("获取属性name："+bean.getName());
