今天完成的事情：

通过映射和工厂模式来初始化对象

UserFactory

package org.example.Factory;

import org.example.dao.UserDao;
import org.example.entity.UserEntity;

public class UserFactory {
    public static UserEntity getUserEntity() throws ClassNotFoundException, InstantiationException, IllegalAccessException {
        Class<?> aClass = Class.forName("org.example.entity.UserEntity");
        UserEntity userEntity = (UserEntity) aClass.newInstance();
        return userEntity;
    }
}

beans.xml

<?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 id="userEntity" class="org.example.entity.UserEntity"/>
</beans>

Test

import org.example.Factory.UserFactory;
import org.example.dao.UserDao;
import org.example.entity.UserEntity;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Test {
    public static void main(String[] args) throws ClassNotFoundException, InstantiationException, IllegalAccessException {
        UserEntity userEntity = UserFactory.getUserEntity();
        userEntity.addUser();
    }
}

明天计划的事情：继续学习spring

遇到的问题：学的有点不太懂

收获：学到了通过映射和工厂模式来初始化对象
