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
package com.xfwl.spring.assem;
/**
* Pojo实体类
* @author Jason
*
*/
public class UserBean {
private String uname;
private String upwd;
public UserBean(){}
public UserBean(String uname,String upwd){
this.uname=uname;
this.upwd=upwd;
}
public String getUname() {
return uname;
}
public void setUname(String uname) {
this.uname = uname;
}
public String getUpwd() {
return upwd;
}
public void setUpwd(String upwd) {
this.upwd = upwd;
}
@Override
public String toString() {
return "UserBean [uname=" + uname + ", upwd=" + upwd + "]";
} }
创建一个管理类：Manager.java
package com.xfwl.spring.assem; import java.util.List;
import java.util.Map;
import java.util.Properties;
import java.util.Set;
/**
*
* @function
* @author 小风微凉
* @time 2018-7-10 上午11:32:01
*/
public class Manager{
private long id;
private List<UserBean> userList;
private Map<String,UserBean> userMap;
private Properties userProps;
private Set<UserBean> userSet;
private String[] userArr; /****getter和setter*******/
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public List<UserBean> getUserList() {
return userList;
}
public void setUserList(List<UserBean> userList) {
this.userList = userList;
}
public Map<String, UserBean> getUserMap() {
return userMap;
}
public void setUserMap(Map<String, UserBean> userMap) {
this.userMap = userMap;
}
public Properties getUserProps() {
return userProps;
}
public void setUserProps(Properties userProps) {
this.userProps = userProps;
}
public Set<UserBean> getUserSet() {
return userSet;
}
public void setUserSet(Set<UserBean> userSet) {
this.userSet = userSet;
}
public String[] getUserArr() {
return userArr;
}
public void setUserArr(String[] userArr) {
this.userArr = userArr;
} }
