使用Maven构建Spring项目“HelloWorld”

傷城~ 2022-06-13 04:36 265阅读 0赞

开始学习Spring，因为以前都没用过Maven，所以打算边学习Spring边熟悉Maven。这里自己使用Maven构建一个spring项目demo

1、新建maven项目：  
![新建maven项目][maven]

![新建maven项目][maven 1]

2、构建Spring环境：  
打开maven项目根目录中的`pom.xml`，点击`dependencies`添加`add`:

*  groupId: org.springframework
 *  artifactId: spring-context
 *  version: 4.3.9.RELEASE

保存pom.xml后如果显示下图说明Spring环境搭建成功了：

3、创建bean类

package com.gisxx.springTest;
    
    public class TestBean {
        private String name;
    
        public TestBean() {
    
        }
    
        public TestBean(String name) {
            super();
            this.name = name;
        }
    
        public String getName() {
            return name;
        }
    
        public void setName(String name) {
            this.name = name;
        }
    
        public void hello(){
            System.out.println("Hello "+this.getName());
        }
    
    
    }

4、创建Bean配置文件  
我在bean的同级目录下创建`beans.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" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd">
    
            <bean id="testBean" class="com.gisxx.springTest.TestBean">
                    <property name="name" value="肖大昕 " />
            </bean>
    </beans>

5、测试

package com.gisxx.springTest;
    
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    
    public class App { 
        public static void main( String[] args )
        {
            ApplicationContext context=new ClassPathXmlApplicationContext("com/gisxx/springTest/beans.xml");
            TestBean test=(TestBean)context.getBean("testBean");
            test.hello();
            ((ClassPathXmlApplicationContext)context).close();
    
        }
    }

控制台输出：

> Hello 肖大昕
