Spring-Bean-配置bean-案例二：通过abstract属性创建一个模板bean

案例二：通过abstract属性创建一个模板bean

（1）编写一个类

public class Person {
    private String name;
    private Integer age;
    private String gender;

    public Person() {
    }

    public Person(String name, Integer age, String gender) {
        this.name = name;
        this.age = age;
        this.gender = gender;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public String getGender() {
        return gender;
    }

    public void setGender(String gender) {
        this.gender = gender;
    }

    @Override
    public String toString() {
        return "Person{" +
                "name='" + name + '\'' +
                ", age=" + age +
                ", gender='" + gender + '\'' +
                '}';
    }
}

 

（2）配置文件

<!--  abstract="true"：这个bean的配置是一个抽象的，不能获取它的实例，只能被别人继承  -->
<bean id="person" class="com.orz.spring.bean.Person" abstract="true">
    <property name="name" value="李华"/>
    <property name="age" value="18"/>
    <property name="gender" value="男"/>
</bean>

 

（3）测试

@Test
public void test1()
{
    ApplicationContext applicationContext=new ClassPathXmlApplicationContext("bean.xml");
    Person person = applicationContext.getBean("person", Person.class);
    System.out.println(person);
}

（4）结果

org.springframework.beans.factory.BeanIsAbstractException:

Error creating bean with name 'person': Bean definition is abstract
