spring入门步骤

步骤一:下载spring的开发包

http://repo.spring.io/webapp/search/artifact/?0&q=spring-framework

解压:(Spring目录结构:)

* docs :API和开发规范.

* libs :jar包和源码.

* schema :约束.

步骤二:创建Web项目,引入spring开发jar包

核心jar包四个:bean/Core/Context/Expression Language

两个开发包 : log日志包/log4j包

步骤三:创建包结构

    com.itheima.spring.demo1

    * UserService

    * UserServiceImpl

步骤四:创建Spring的配置文件

文件名最好叫:  applicationContext.xml

引入Schema约束:    查找方法>

* spring-framework-3.2.0.RELEASE\docs\spring-framework-reference\html\xsd-config.html

<? 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">
</ beans >

完成配置:

<? 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">
<!-- bean definitions here -->
    < bean id = "studentService" class = "com.mickeymouse.ioc.StudentServiceImpl" ></ bean >
</ beans >

步骤五:编写测试代码

@Test
    public void test1(){
        //获取配置文件
        String path = "applicationContext.xml";
        //加载配置文件
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext(path);
        StudentService studentService = (StudentService) applicationContext.getBean("studentService");
        studentService.addStudent();
    }
