一、建立项目
二、添加Spring的库文件
三、添加Spring配置文件
四、编写Bean类
代码：
public class User {
private int id;
private String userName;
private String passWord;
public User() {
super();
// TODO Auto-generated constructor stub
}
public User(int id, String userName, String passWord) {
super();
this.id = id;
this.userName = userName;
this.passWord = passWord;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassWord() {
return passWord;
}
public void setPassWord(String passWord) {
this.passWord = passWord;
}
@Override
public String toString() {
return "User [id=" + id + ", passWord=" + passWord + ", userName="
+ userName + "]";
}
}
五、编写配置文件
代码：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
<bean id="user" class="com.vo.User">
<property name="passWord">
<value>123</value>
</property>
<property name="userName">
<value>admin</value>
</property>
<property name="id">
<value>1</value>
</property>
</bean>
</beans>
六、测试
代码：
public class Test {
public static void main(String[] args) {
BeanFactory beanFactory = new ClassPathXmlApplicationContext("applicationContext.xml");
User user = (User)beanFactory.getBean("user");
System.out.println(user);
}
}
