MyEclipse 10.7 + Spring 4.2手动配置

利用MyEclipe自带的Spring

1,创建项目

  打开MyEclipse, 选择 File -> New -> Java Project

2, 添加Spring 3.1

  选中新建的项目，右健 My Eclipse -> Add Spring Capabilities, 勾选 Spring 3.1 Core Libaries

以上方式可以简单的为项目添加Spring框架，但限制条件是Spring 版本只能为3.1

 

手动添加Spring 4.2

1, 下载必要的jar包

    通过http://repo.spring.io/milestone/org/springframework/地址，逐个下载以下文件

commons-logging.jar
spring-aop-4.2.0.RC3.jar               
spring-beans-4.2.0.RC3.jar
spring-context-4.2.0.RC3.jar           
spring-context-support-4.2.0.RC3.jar
spring-core-4.2.0.RC3.jar              
spring-expression-4.2.0.RC3.jar

2，把上面的包加到编译路径中

 

3，参照http://projects.spring.io/spring-framework/入门示例，Copy代码

MessageService.java

package com.bf;

public interface MessageService {
    String getMessage();
}

MessagePrinter.java

package com.bf;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class MessagePrinter {

    final private MessageService service;

    @Autowired
    public MessagePrinter(MessageService service) {
        this.service = service;
    }

    public void printMessage() {
        System.out.println(this.service.getMessage());
    }
}

Application.java

package com.bf;

import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.*;

@Configuration
@ComponentScan
public class Application {

    @Bean
    MessageService mockMessageService() {
        return new MessageService() {
            public String getMessage() {
              return "Hello World!";
            }
        };
    }

  public static void main(String[] args) {
      ApplicationContext context = 
          new AnnotationConfigApplicationContext(Application.class);
      MessagePrinter printer = context.getBean(MessagePrinter.class);
      printer.printMessage();
  }
}

applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans 
           http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-3.0.xsd">
	
	<context:annotation-config />  <!--可以不要这一行-->
	<context:component-scan base-package="com.bf"/><!--可以不要这一行-->

</beans>

编译通过过，直接点击Run Application, 输出“Hello World”
