0320-springioc+maven/Junit@Test注

• 依赖包：

    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-context</artifactId>
      <version>5.1.13.RELEASE</version>
    </dependency>

会同时加载好多个包，关于spring jar包的依赖：

• 配置applicationContext.xml
  路径为src/main/resources
  内容：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       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 ">
    <!-- 把一个对象放进Spring容器 -->
    <!-- 用property设置对象的属性（要求对象要有setter方法，还要有一个无参数的构造方法 -->
    <bean name="s1" class="com.pojo.User">
        <property name="stuNum" value="20"></property>
        <property name="name" value="小红"></property>
        <property name="Wish" value="laodazuishuai"></property>
    </bean>
    <!-- 另一个对象-->
    <bean name="s2" class="com.pojo.User">
        <property name="stuNum" value="21"></property>
        <property name="name" value="小白"></property>
        <property name="wish" value="老大最帅吗？"></property>
    </bean>
</beans>

• test文件
  和原来的test文件放在同一个文件夹下就好（test-java-com.pojo)

public class test1 {
    //Junit中的一个注解，标注当前这个方法需要做为test case运行
    @Test
    public void studentTest(){
        ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
        //spring容器管理的对象引入（可初始化/aop后构造加强版代理类
        User s1 = applicationContext.getBean("s1", User.class);
        User s2 = applicationContext.getBean("s2", User.class);

        //mybatis配置读取+session/mapper获取
        String resource="mybatis-config.xml";
        Reader reader=null;
        try {
            reader= Resources.getResourceAsReader(resource);
        } catch (IOException e) {
            e.printStackTrace();
        }
        SqlSessionFactory sqlMapper=new SqlSessionFactoryBuilder().build(reader);
        SqlSession session=sqlMapper.openSession();
        UserDao mapper = session.getMapper(UserDao.class);

        //测试与输出
        mapper.setWish(s1);
        mapper.setWish(s2);
        s1=mapper.findById(20);
        s2=mapper.findById(21);
        System.out.println(s1.getWish());
        System.out.println(s1.getName());
        System.out.println(s2.getName());
        session.close();
    }
}
