Spirng setter 注入简单
1. 提供相应要注入的属性
//setter注入 public class Bean2 { private String name; private Integer age; // 提供要注入的属性相应的setter方法 public void setName(String name) { this.name = name; } public void setAge(Integer age) { this.age = age; } public void show() { System.out.println("bean2:" + name + "," + age); } }
2. 为每一个要注入的属性提供相应的标准封装setter方法
3. 在配置中为Bean指定要注入的属性,使用property元素name=“属性”value=“值”
<!-- setter注入 --> <bean id="bean2" class="com.hao947.bean.Bean2"> <property name="name" value="hao947"/> <property name="age" value="947"></property> </bean>
<propertyname = “属性” value=”值”>
測试
@Test public void show_setter() { ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml"); Bean2 bean2 = (Bean2) ac.getBean("bean2"); bean2.show(); }
