Spring工厂模式

Spring工厂模式

//实体类
package com.msb.pojo;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Demo1 {
    private String bname;
    private String author;

}

创建类继承FactoryBean
package com.msb.pojo;
import org.springframework.beans.factory.FactoryBean;

public class BookFactory implements FactoryBean<Demo1> {
    @Override
    public Demo1 getObject() throws Exception {
        Demo1 demo1 =new Demo1();
        demo1.setAuthor("新设置");
        demo1.setBname("设置名字");
        return demo1;
    }

    @Override
    public Class<?> getObjectType() {
        return null;
    }
}

spring.xml代码模块

<?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.xsd">
<bean id="Demo1" class="com.msb.pojo.BookFactory"></bean>
</beans>

测试方法

import com.msb.pojo.Demo1;
import javafx.application.Application;
import org.junit.Test;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class test2 {
    @Test
            public void test1(){
        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext1.xml");
        Demo1 demo1 = context.getBean("Demo1",Demo1.class);
        System.out.println(demo1);
    }
}
