Web项目搭建&集成Spring框架

Web项目搭建

1.新建Maven项目：springmvc-mybatisdemo

2.配置Maven仓库文件

3.Maven项目创建，添加Web文件夹：点击参考岁岁博客

 

集成Spring框架

1.添加spring相关依赖：pop.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <project xmlns="http://maven.apache.org/POM/4.0.0"

87         </dependency>
88     </dependencies>
89 </project>

 

2.在resources文件下新建配置文件：applicationContext.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4        xmlns:context="http://www.springframework.org/schema/context"
 5        xmlns:tx="http://www.springframework.org/schema/tx"
 6        xsi:schemaLocation="http://www.springframework.org/schema/beans
 7        http://www.springframework.org/schema/beans/spring-beans.xsd
 8         http://www.springframework.org/schema/tx
 9         http://www.springframework.org/schema/tx/spring-tx.xsd
10         http://www.springframework.org/schema/context
11         http://www.springframework.org/schema/context/spring-context.xsd">
12     <context:component-scan base-package="com"/>
13 </beans>

 

3.在web文件夹中添加配置文件：web.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
 3          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4          xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
 5          version="4.0">
 6     <display-name>
 7         Archetype Created Web Application
 8     </display-name>
 9     <context-param>
10         <param-name>contextConfigLocation</param-name>
11         <param-value>classpath:applicationContext.xml</param-value>
12     </context-param>
13     <listener>
14         <listener-class>
15             org.springframework.web.context.ContextLoaderListener
16         <stener-class>
17     <stener>
18 </web-app>

 

4.在src/main/test目录下创建一个包"com",在包里新建一个类:SpringTest.java

 1 package com;
 2 
 3 
 4 import org.junit.jupiter.api.Test;
 5 import org.springframework.context.ApplicationContext;
 6 import org.springframework.context.support.ClassPathXmlApplicationContext;
 7 import org.springframework.stereotype.Service;
 8 
 9 @Service
10 public class SpringTest {
11 
12     @Test
13     public void testSpring(){
14         ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
15 
16         SpringTest springTest = (SpringTest) applicationContext.getBean("springTest");
17 
18         springTest.sayHello();
19     }
20     public  void  sayHello(){
21         System.out.println("hello ss");
22     }
23 }

 

执行结果：

 

 

 

总结：

@Service: Spring会自动扫描到@Service注解的类，并把这些类放入Spring容器中管理。

<context:component-scan>注解：扫描base-package包或者子包下的所有Java类，并把匹配的Java类注册成Bean。
