Spring framework configuration and simple instances under the latest Eclipse IDE, eclipsespring
Some time ago, I started to learn the Spring framework. I bought books and read videos to find tutorials. However, I rarely introduced how to configure Spring + Eclipse. Now I will share my successful experiences with you. Some of the source code of this article comes from the Code agricultural Tutorial: http://www.manongjc.com/spring/spring_environment_setup.html in the text is not correct, please correctI. preparations:① Install Java jdk.Click JDK download at http://www.oracle.com/technetwork/java/javase/downloads/index-jsp-138363.html.For more information about environment variables, see other online tutorials. Http://jingyan.baidu.com/article/db55b609ab421f4ba30a2f04.html② Install Eclipse software.Http://www.eclipse.org/downloads /. The latest version is eclipse neon. Select the 32/64-bit version based on your local machine.Open the eclipse-inst-win. Program and select the first item: Eclipse IDE for Java Developers for online installation.
③ Download the Spring framework.　　　　　　　　Http://repo.spring.io/release/org/springframework/spring/4.3.3.RELEASE/ I use the latest version 4.3.3 here, previous versions can be downloaded on the previous page of the website. Download the first one. Just download the dist.zip file.④ Download the Commons_Logging package.Click commons-logging-1.2-bin.zip under binariesto download the http://commons.apache.org/proper/commons-logging/download_logging.cgi.Ii. Configuration:Unzip the jar files in the/libdirectory, and choose the commons-logging-1.2.jar files in the commons-logging-1.2-bin.zip directory. Now, Environment configuration is complete. 3. simple instance: Create the com. manongjc package in the src folder, and create the HelloWorld class and MainApp class respectively in the package. The Code is as follows:

package com.manongjc;public class HelloWorld {   private String message;   public void setMessage(String message){      this.message  = message;   }   public void getMessage(){      System.out.println("Your Message : " + message);   }}

 

 

package com.manongjc;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class MainApp {   public static void main(String[] args) {      ApplicationContext context =              new ClassPathXmlApplicationContext("Beans.xml");      HelloWorld obj = (HelloWorld) context.getBean("helloWorld");      obj.getMessage();   }}

 

 

Create the beans. xml file in the src folder. The Code is as follows:

 1 <?xml version="1.0" encoding="UTF-8"?> 2  3 <beans xmlns="http://www.springframework.org/schema/beans" 4     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 5     xsi:schemaLocation="http://www.springframework.org/schema/beans 6     http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> 7  8    <bean id="helloWorld" class="com.manongjc.HelloWorld"> 9        <property name="message" value="Hello World!"/>10    </bean>11 12 </beans>

 

 

Run the command in explanation. The console outputs: Your Message: Hello World! I hope this article will help you. If you need to repost it, please indicate the source, love sharing, and reject it. The blog spirit will last forever-cvrigo
