第二章:Spring框架代码的编写
1. 搭建和测试Spring的开发环境
1. 在resources下创建spring.xml的配置文件,编写具体的配置信息。
<?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:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd">
<!--开启注解扫描,要扫描的是service-->
<context:component-scan base-package="com.qcby"/>
</beans>
2. 在ssm_web项目中,在src下创建test目录,编写测试方法,进行测试
package com.qcby.demo;
import com.qcby.service.AccountService;
import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class TestSpring {
@Test
public void run(){
ClassPathXmlApplicationContext ac = new ClassPathXmlApplicationContext("classpath:spring.xml");
AccountService service = ac.getBean(AccountService.class);
service.findAll();
}
}
测试一下能不能调用测试方法,
出现上述内容测试完成。
