@Target(ElementType.METHOD)
public @interface MyRequired {
}
9.在src/main/resource下创建bean的配置文件spring-bean.xml,如图所示
10.配置文件spring-bean.xml的内容如下
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd "> <!-- 设置自定义的注解 --> <bean class="org.springframework.beans.factory.annotation.RequiredAnnotationBeanPostProcessor"> <property name="requiredAnnotationType" value="com.mycompany.shequ.annotaion.MyRequired"> </property> </bean> <bean id="forumpostbean" class="com.mycompany.shequ.bean.ForumPost"> <property name="pid" value="1"></property> <property name="name" value="自定义注解"></property> <property name="forum" ref="forumbean"></property> </bean> <bean id="forumbean" class="com.mycompany.shequ.bean.Forum"> <property name="fid" value="1"></property> <property name="name" value="被依赖的bean"></property> </bean> </beans>
11.在src/main/resource下创建核心的配置文件applicationContext.xml,如图所示
12.核心的配置文件applicationContext.xml的内容如下
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd"> <import resource="bean/spring-bean.xml"/> </beans>

public class AppTest {
@Test
public void beanTest(){
ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
ForumPost forumPost = (ForumPost)context.getBean("forumpostbean");
System.out.println(forumPost);
}
}
15.在测试类AppTest的beanTest方法上右键运行,输出结果如图所示
