1、创建项目

点击“Create New Project”,新建项目

spring框架构建 spring框架步骤_spring

选择Maven项目

spring框架构建 spring框架步骤_Spring_02

项目配置

spring框架构建 spring框架步骤_xml_03

使用本地安装的Maven

spring框架构建 spring框架步骤_Spring_04

一直点击Next,最后点击完成
当控制台中出现“BUILD SUCCESS”,项目创建成功

2、加载依赖

在pom.xml文件中添加Spring依赖和日志相关依赖

<dependencies>
  <!--测试相关-->
  <dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.11</version>
    <scope>test</scope>
  </dependency>
  <!--Spring核心基础依赖-->
  <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>5.0.2.RELEASE</version>
  </dependency>
  <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>5.0.2.RELEASE</version>
  </dependency>
  <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-beans</artifactId>
    <version>5.0.2.RELEASE</version>
  </dependency>
  <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-expression</artifactId>
    <version>5.0.2.RELEASE</version>
  </dependency>
  <!--日志相关-->
  <dependency>
    <groupId>commons-logging</groupId>
    <artifactId>commons-logging</artifactId>
    <version>1.2</version>
  </dependency>
  <dependency>
    <groupId>log4j</groupId>
    <artifactId>log4j</artifactId>
    <version>1.2.17</version>
  </dependency>
</dependencies>

 

 

3、代码实现

在main目录下面创建java和resources目录

spring框架构建 spring框架步骤_Spring_06

分别在java和resources目录上点击右键,分别选择Mark Directory as-->Sources Root 和 Mark Directory as -->Resources Root,设置为源码目录和资源目录

spring框架构建 spring框架步骤_Test_07

创建dao包,在dao包下创建TestDao接口和TestDao接口的实现类,结构如下图:

spring框架构建 spring框架步骤_Test_08

TestDao接口代码示例:

package dao;

public interface TestDao {
    public void sayHello();
}

TestDaoImpl实现类代码示例:

package dao;

public class TestDaoImpl implements TestDao {
    @Override
    public void sayHello() {
        System.out.println("Hello,Spring!");
    }
}

在resources资源目录点击右键,依次选择New-->XML Configuration File-->Spring Config,创建applicationContext.xml的配置文件

spring框架构建 spring框架步骤_spring_09

applicationContext.xml配置文件代码示例:

<?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.xsd">

    <!--把testDao对象的创建权交给Spring-->
    <bean id="testDao" class="dao.TestDaoImpl"></bean>

</beans>

创建test包,在test包下创建测试类SpringTest

spring框架构建 spring框架步骤_spring_10

SpringTest类代码示例:

package test;

import dao.TestDao;
import org.junit.jupiter.api.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class SpringTest {

    @Test
    public void demo(){
        //初始化Spring容器ApplicationContext,加载配置文件
        ApplicationContext application = new ClassPathXmlApplicationContext("applicationContext.xml");
        //通过容器获取testDao实例
        TestDao testDao = (TestDao) application.getBean("testDao");
        testDao.sayHello();
    }

}

点击测试方法左侧的运行按钮,选择Run,测试代码
