簡單的說一下spring的搭建流程,內容偏基礎,底子很差的能夠看一下!java
如圖所示:找到以前準備好的文件路徑面試
一、新建UserService接口
二、新建UserService實現類
三、經過bean將UserService放入容器
四、經過context的getbean方法拿到UserService對象spring
代碼以下:express
<dependencies> <!-- https://mvnrepository.com/artifact/org.springframework/spring-core --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>5.2.13.RELEASE</version> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework/spring-beans --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>5.2.13.RELEASE</version> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework/spring-context --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>5.2.13.RELEASE</version> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework/spring-expression --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-expression</artifactId> <version>5.2.13.RELEASE</version> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework/spring-aop --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>5.2.13.RELEASE</version> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework/spring-jcl --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jcl</artifactId> <version>5.2.13.RELEASE</version> </dependency>
後刷新Maven.架構
<?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 https://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/util https://www.springframework.org/schema/util/spring-util.xsd "> </beans>
點右上角提示的「Configure application context」就能夠了。

編寫代碼學習
代碼以下
測試
新建class文件UserServiceImpl
spa
public class DemoTest { public static void main(String[] args){ ApplicationContext context = new ClassPathXmlApplicationContext ("classpath:applicationContext.xml"); UserSvice service = (UserSvice) context.getBean("userService"); service.saveUser(); } }
如圖:
