SpringIOC通过配置XML

• 加入依赖或者jar包

<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-context</artifactId>
			<version>4.3.9.RELEASE</version>
</dependency>

• 写几个类

public class MyController {
    
    

    public MyService2 getMyService2() {
    
    
        return myService2;
    }

    public void setMyService2(MyService2 myService2) {
    
    
        this.myService2 = myService2;
    }

    private MyService myService;

    private MyService2 myService2;

    public MyController(MyService myService) {
    
    
        this.myService = myService;
    }

    public String doSomething(int id, String name) {
    
    
        System.out.println("id:" + id + "name:" + name);
        doTry();
        return "id>" + id + "name<" + name;
    }

    public void doTry() {
    
    
        System.out.println(System.currentTimeMillis());
        myService.doService();
        myService2.doService();
    }
}

-------------------------------------------------
public class MyService {
    
    

    public void doService() {
    
    
        System.out.println("service....");
    }
}


------------------------------------------------------
public class MyService2 {
    
    

    public void doService() {
    
    
        System.out.println("service2....");
    }
}

---------------------------------------------
public class MyController {
    
    

    public MyService2 getMyService2() {
    
    
        return myService2;
    }

    public void setMyService2(MyService2 myService2) {
    
    
        this.myService2 = myService2;
    }

    private MyService myService;

    private MyService2 myService2;

    public MyController(MyService myService) {
    
    
        this.myService = myService;
    }

    public String doSomething(int id, String name) {
    
    
        System.out.println("id:" + id + "name:" + name);
        doTry();
        return "id>" + id + "name<" + name;
    }

    public void doTry() {
    
    
        System.out.println(System.currentTimeMillis());
        myService.doService();
        myService2.doService();
    }
}

-------------------------------------------

public class UserTO {
    
    

    private String id;
    private String name;
    private int age;
    private String gender;
}
    

• 配置spring.XML 文件

<?xml version="1.0" encoding="UTF-8"?>
<beans default-lazy-init="true"
    xmlns="http://www.springframework.org/schema/beans"

    	<!-- 配置bean -->
       <bean id = "myService" class="com.feifan.service.MyService"></bean>
       
       <bean id = "myService2" class="com.feifan.service.MyService2"></bean>
       
       <bean id = "userTO" class="com.feifan.compent.UserTO"></bean>
       <bean id = "myController" class="com.feifan.controller.MyController">
       		<!-- 构造注入参数 -->
       		<constructor-arg name="myService" ref="myService"></constructor-arg>
       		<!-- set 注入参数 -->
       		<property name="myService2" ref="myService2"></property>
       </bean>
       
</beans>

• 测试容器

public static void main(String[] args) {
    
    
        ClassPathXmlApplicationContext cac = new ClassPathXmlApplicationContext("classpath:configs/spring-config.xml");
        System.out.println(cac.getDisplayName());
        System.out.println(cac.getBeanDefinitionCount());
        ((MyService)cac.getBean("myService")).doService();
        System.out.println(((MyController)(cac.getBean("myController"))).doSomething(9, "f"));
        System.out.println(cac.getBean("userTO"));
        System.out.println(cac.getId());
        cac.close();
    }
