<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<bean id="user" class="com.gosuncn.User"></bean>
</beans>
```
##### 创建一个User类
```java
package com.gosuncn;
import lombok.Data;
@Data
public class User {
private String username;
private String password;
}
```
##### 单元测试
```java
public class SpringTest {
@Test
public void test01() {
ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
User user = (User) ctx.getBean("user");
System.out.println(user);
}
}
```
