IOC控制反转（2）set和有参构造函数注入

1、Book类定义

package com.example.springioc.module;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Book {
    
    private String name;

    
    private String auther;
}

2、bean文件

3、测试代码

package com.example.springioc;

import com.example.springioc.module.Book;
import com.example.springioc.module.User;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

@SpringBootTest
class SpringIocApplicationTests {

    @Test
    void contextLoads() {
    }

    @Test
    public void testBookSetterDI() {
        ApplicationContext context = new ClassPathXmlApplicationContext("bean1.xml");
        Book book = context.getBean("book1", Book.class);
        System.out.println("Book:" + book);

        book = context.getBean("book2", Book.class);
        System.out.println("Book2:" + book);
    }

}

运行结果：
