从头认识Spring-2.6 在注解中使用表达式@Value（1）-注入普通值

这一章节我们来讨论一下在注解中使用表达式@Value注入普通值。

1.domain

厨师类：

package com.raylee.my_new_spring.my_new_spring.ch02.topic_1_17;

import org.springframework.beans.factory.annotation.Value;

public class Chief {

	@Value("jack")
	private String name = "";

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

}

2.测试类：

package com.raylee.my_new_spring.my_new_spring.ch02.topic_1_17;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {
		"/com/raylee/my_new_spring/my_new_spring/ch02/topic_1_17/ApplicationContext-test.xml" })
public class ChiefTest {

	@Autowired
	private ApplicationContext applicationContext;

	@Test
	public void testChief() {
		Chief jack = applicationContext.getBean(Chief.class);
		System.out.println(jack.getName());
	}
}

	<bean id="jack"
		class="com.raylee.my_new_spring.my_new_spring.ch02.topic_1_17.Chief" />
</beans>

测试输出：

jack
