maven 项目简单搭建spring运行环境

1.idea 新建maven项目。

2.pom.xml中引入spring的核心jar包。

       <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>5.2.8.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>5.2.8.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-beans</artifactId>
            <version>5.2.8.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>5.2.8.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.13</version>
            <scope>test</scope>
        </dependency>

3.配置bean.xml在resources下（刚开始引入的路径错误，在src下maven项目并不能找到）

<?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-2.5.xsd">
    <bean id="user" class="zdc.User"></bean>
</beans>

4.在test目录下编写测试类进行测试。

    @Test
    public void demo(){
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("bean.xml");
        User user = applicationContext.getBean("user",User.class);
        user.setName("zdc");
        String s = user.toString();
        System.out.println(s);
    }
