1、首先准备共享文件
调用方法Client端Client.java:
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Client {
    public static void main(String[] args) {
        //创建容器
        ClassPathXmlApplicationContext cac = new ClassPathXmlApplicationContext("service.xml");
        //获取bean对象
        CustomerServiceImpl cs = (CustomerServiceImpl) cac.getBean("CustomerServiceImpl");
        //调用方法
        cs.saveCustomer();
    }
}

接口文件CustomerService.java:

public interface CustomerService {
    void saveCustomer();
}

2、构造函数方式注入:
Spring配置文件,Service.xml:

注入bean类文件:CustomerServiceImpl.java

public class CustomerServiceImpl implements CustomerService {
    private String name ;
    private Integer age;

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

    @Override
    public void saveCustomer() {
        System.out.println("CustomerServiceImpl-saveCustomer-" + name + "-" + age);
    }
}

3、set方法注入
Spring配置文件,Service.xml:

注入bean类文件:CustomerServiceImpl.java:

public class CustomerServiceImpl implements CustomerService {
    private String name ;
    private Integer age;

    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;
    }

    @Override
    public void saveCustomer() {
        System.out.println("CustomerServiceImpl-saveCustomer-" + name + "-" + age);
    }
}
