在IDEA下快速创建一个Spring项目

在这里需要特别注意的是，将create empty spring-config.xml选中，这样会自动生成一个xml文件，然后将xml文件的名字改成自己需要的名字，楼主在这里改成了beans.xml。

给工程命名和选择工作空间，点击finisn，这里将会自动下载需要的配置。

package com.sakura.spring.helloworld.bean;
    
    public class HelloWorld {
        private String name;
        private int age;
        private String gender;
    
        public Void hello(){
            System.out.println("Hello:" + name );
            return null;
        }
    
        public HelloWorld(){}
    
        public HelloWorld(String name, int age, String gender) {
            this.name = name;
            this.age = age;
            this.gender = gender;
        }
    
        public String getName() {
            return name;
        }
    
        public void setName(String name) {
            this.name = name;
        }
    
        public int getAge() {
            return age;
        }
    
        public void setAge(int age) {
            this.age = age;
        }
    
        public String getGender() {
            return gender;
        }
    
        public void setGender(String gender) {
            this.gender = gender;
        }
    
        @Override
        public String toString() {
            return "HelloWorld{" +
                    "name='" + name + '\'' +
                    ", age=" + age +
                    ", gender='" + gender + '\'' +
                    '}';
        }
    }

1使用传统的调用方式调用； 2ApplicationContext容器调用方式调用；3 XmlBeanFactory容器调用。如下所示。

package com.sakura.spring.helloworld.main;
    
    import com.sakura.spring.helloworld.bean.HelloWorld;
    import org.springframework.beans.factory.xml.XmlBeanFactory;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    import org.springframework.core.io.ClassPathResource;
    
    public class MainApplication {
        public static void main(String[] args) {
    
    //       1  传统方法
    //        HelloWorld helloWorld = new HelloWorld();
    //        helloWorld.setAge(10);
    //        helloWorld.setName("Roc Lau");
    //        helloWorld.setGender("Male");
    //        helloWorld.hello();
    
    //        2  Spring ApplicationContext容器
    //        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("beans.xml");
    //        HelloWorld helloWorld = (HelloWorld) applicationContext.getBean("HelloWorld");
    //
    //        System.out.println("HelloWorld:" + helloWorld);
    
    //       3   Spring XmlBeanFactory容器
            XmlBeanFactory xmlBeanFactory = new XmlBeanFactory(new ClassPathResource("beans.xml"));
            HelloWorld helloWorld = (HelloWorld) xmlBeanFactory.getBean("HelloWorld");
            System.out.println("HelloWorld:" + helloWorld);
        }
    }

3.配置bean文件。

<?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:util="http://www.springframework.org/schema/util"
           xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd">
        <bean id="HelloWorld" class="com.sakura.spring.helloworld.bean.HelloWorld">
            <property name="name" value="Roc Lau"></property>
        </bean>
        
    </beans>

4.运行结果如下:
