学习笔记——Spring中组件扫描（包含扫描、排除扫描）、Spring中完全注解开发；Spring整合Junit4步骤

<context:component-scan base-package="com.hh"></context:component-scan>

<context:component-scan base-package="com.hh" use-default-filters="false">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Repository"/>
<!--        <context:include-filter type="assignable" expression="com.hh.service.DeptService"/>-->
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Service"/>
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

<context:component-scan base-package="com.hh" use-default-filters="false">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

@Configuration
@ComponentScan(basePackages = "com.hh")
public class SpringConfig {
}

public class Test0Xml {
    @Test
    public void test0Xml(){
        //创建一个容器对象
//        ApplicationContext context = new ClassPathXmlApplicationContext("");

        ApplicationContext context =
                new AnnotationConfigApplicationContext(SpringConfig.class);

        DeptDaoImpl deptDao = context.getBean("DeptDao", DeptDaoImpl.class);
        System.out.println("deptDao = " + deptDao);
    }
}
