setter and contructor di

In spring, we always use Setter or Contructor ways to create beans. Here let’s see it:

The bean class is:

public class Id {  
    private int id;  
    private String name;  
    public int getId() {  
        return id;  
    }  
    public void setId(int id) {  
        this.id = id;  
    }  
    public String getName() {  
        return name;  
    }  
    public void setName(String name) {  
        this.name = name;  
    }  
}

the Id_Bean.xml file:

<?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">  

    <bean id="id" class="com.kincolle.Id">  
    <property name="id" value="1"></property>  
    <property name="name" value="kincolle"></property>  
    </bean>  
</beans> 

test it:

public class IdTest {  
    public static void main(String[] args){  
        ClassPathXmlApplicationContext context = new   
                ClassPathXmlApplicationContext("com/kincolle/Id_Bean.xml");  
        Id id = (Id)context.getBean("id");  
        System.out.println(id.getId());  
        System.out.println(id.getName());  
    }  
}  

the Result will be

1 kincolle

The bean class is:

public class Id {  
    private int id;  
    private String name;  
    // use constructor to create bean
    public Id(int id,String name){  
        this.id = id;  
        this.name = name;  
    }  
    public int getId() {  
        return id;  
    }  
    public void setId(int id) {  
        this.id = id;  
    }  
    public String getName() {  
        return name;  
    }  
    public void setName(String name) {  
        this.name = name;  
    }  
}  

the Id_Bean.xml file:

<?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">  

    <bean id="id" class="com.kincolle.Id">  
    <constructor-arg index="0" value="1"></constructor-arg>  
    <constructor-arg index="1" value="kincolle"></constructor-arg>  
    </bean>  
</beans>  

test it:

1 kincolle
