On the way learning spring 1

Spring 8 - Setting Beans Properties

1. Add new parameter 'sexId' in Java class "Person" and also add 'setsexId()' method in it

2. Insert 'property' in beans.xml. Source code is:

<bean id="person"
class="com.caveofprogramming.spring.test.Person">
<constructor-arg value="777" name="id" type="int"></constructor-arg>
<constructor-arg value="Mary" name="name" type="String"></constructor-arg>
<property name="taxId" value="123"></property>
</bean>

 

 

3. Delete the old toString method in Person Java class, then Generate new 'toString()' method

 

Spring 9 - Dependency Injectrion

1. Add a new Java class 'Adress' in the floder which same with App.java;

2. Add this Java class in 'beans.xml' as a new bean; Then set constructor-arg(same in Spring 8 - Person);

3. Add the corresponding java code in App.class, and run it;

   Address address = (Address) context.getBean("address");
   System.out.println(address);

 4.Add  Address object in Person.class, then regenerate the toString() method.

5.In beans.xml,  inject property in person bean . Source code is:   (Dependency Injectrion)

    <bean id="person"
        class="com.caveofprogramming.spring.test.Person">
    <constructor-arg value="777" name="id" type="int"></constructor-arg>
    <constructor-arg value="Mary" name="name" type="String"></constructor-arg>
    <property name="taxId" value="123"></property>
    <property name="address" ref="address"></property>
    </bean>
