        spring-core
        5             
       
        5.0.9.RELEASE
        6         
       7         
      
        8             
       
        org.springframework

        org.springframework
       15             
       
        spring-beans
       16             
       
        5.0.9.RELEASE
       17         
      18         
      19         
      
       20             
       
        org.springframework

        spring-expression
       22             
       
        5.0.9.RELEASE
       23         
      

2.建立User类

1 public class User { 2     private String name; 3     private Integer age; 4  5     public String getName() { 6         return name; 7     } 8  9     public void setName(String name) {10         this.name = name;11     }12 13     public Integer getAge() {14         return age;15     }16 17     public void setAge(Integer age) {18         this.age = age;19     }20 }

3.xml配置

       6  7     
      
        8         
        9     
      10 11     
      
       12         
       13     
      14 15     
      16 17 
     

4.实例化User类

main方法里:

import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext;

1         //位置:setting/applicationContext.xml2         ApplicationContext context = new ClassPathXmlApplicationContext("setting/applicationContext.xml");3         User user = context.getBean("user",User.class);4         System.out.println(user);
