一、通过XML装配Bean

• 装配简易值
• 装配集合
• 命名空间装配（暂不测试）

二、测试例子

创建一个用户类：UserBean.java

1 package com.xfwl.spring.assem; 2 /** 3  * Pojo实体类 4  * @author Jason 5  * 6  */ 7 public class UserBean { 8     private String uname; 9     private String upwd;10     public UserBean(){}11     public UserBean(String uname,String upwd){12         this.uname=uname;13         this.upwd=upwd;14     }15     public String getUname() {16         return uname;17     }18     public void setUname(String uname) {19         this.uname = uname;20     }21     public String getUpwd() {22         return upwd;23     }24     public void setUpwd(String upwd) {25         this.upwd = upwd;26     }27     @Override28     public String toString() {29         return "UserBean [uname=" + uname + ", upwd=" + upwd + "]";30     }    31     32 }

 创建一个管理类：Manager.java

1 package com.xfwl.spring.assem; 2  3 import java.util.List; 4 import java.util.Map; 5 import java.util.Properties; 6 import java.util.Set; 7 /** 8  *  9  * @function  10  * @author 小风微凉11  * @time  2018-7-10 上午11:32:0112  */13 public class Manager{14     private long id;15     private List
     
       userList;16     private Map
      
        userMap;17     private Properties userProps;18     private Set
       
         userSet;19     private String[] userArr;20     21     /****getter和setter*******/22     public long getId() {23         return id;24     }25     public void setId(long id) {26         this.id = id;27     }28     public List
        
          getUserList() {29         return userList;30     }31     public void setUserList(List
         
           userList) {32         this.userList = userList;33     }34     public Map
          
            getUserMap() {35 return userMap;36 }37 public void setUserMap(Map
           
             userMap) {38 this.userMap = userMap;39 }40 public Properties getUserProps() {41 return userProps;42 }43 public void setUserProps(Properties userProps) {44 this.userProps = userProps;45 }46 public Set
            
              getUserSet() {47 return userSet;48 }49 public void setUserSet(Set
             
               userSet) {50 this.userSet = userSet;51 }52 public String[] getUserArr() {53 return userArr;54 }55 public void setUserArr(String[] userArr) {56 this.userArr = userArr;57 }58 59 60 }
