  1. xml配置版：Student、Phone、排序、list、set、map等例子

    • phone

      //实体类

  1. 注解配置版

    • Student

      //基于注解实现的bean对象
@Configuration
public class StudentConfig {
    @Bean
    public Student student(){
        Student student = new Student();
        student.setId(1);
        student.setName("小王");
        List hobbyList = new ArrayList(){{
            this.add("吃饭");
            this.add("睡觉");

        }};
        student.setPhone(phoneList);
        return student;
    }
}
//测试方法
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {StudentConfig.class})
public class StudentConfigTest {
    @Autowired
    private Student student;
    @Test
    public void student() {
        System.out.println(student);
    }
}

  • Grade

    //实体类
@Configuration
public class GradeConfig {
    @Bean
    public Grade grade(){
        Grade grade = new Grade();
        grade.setName("软件1851");
        List phoneList = new ArrayList(){{
            this.add("phone");
        }};
        List hobbyList = new ArrayList(){{
            this.add("吃饭");
            this.add("学习");
        }};
        Map studentMap = new HashMap();
        for(int i =0;i<3;i++){
            Student student = new Student();
            student.setName("小同学"+i);
            student.setId(12+i);
            student.setPhone(phoneList);
            student.setHobbies(hobbyList);
            studentMap.put("student"+i,student);
        }
        grade.setStudents(studentMap);
        return grade;
    }
}
//测试方法
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {GradeConfig.class})
public class GradeConfigTest {
    @Autowired
    private Grade grade;
    @Test
    public void grade() {
        System.out.println(grade);
    }
}

  • phone

    //使用扫包的方法获取bean对象
@Configuration
public class PhoneConfig {
    @Bean
    public Phone phone(){
        Phone phone = new Phone();
        phone.setBrand("苹果");
        phone.setPrice(8000.0);
        return phone;
    }

    public static void main(String[] args) {
        AnnotationConfigApplicationContext ac = new AnnotationConfigApplicationContext(PhoneConfig.class);
        ac.scan("com.soft1851.spring.ioc.config");
        Phone phone = (Phone)ac.getBean("phone");
        System.out.println(phone);

    }
}
