1、spring_helloworld

(1)使用手动加载jar包的方式实现，分为三个步骤，现在几乎不用

导包：导入这五个包即可

commons-logging-1.2.jar

spring-beans-5.2.3.RELEASE.jar

spring-context-5.2.3.RELEASE.jar

spring-core-5.2.3.RELEASE.jar

spring-expression-5.2.3.RELEASE.jar

写配置

Person.java

package com.mashibing.bean; public class Person { private int id; private String name; private int age; private String gender; public int getId() { return id; }public void setId(int id) { this.id = id; }public String getName() { return name; }public void setName(String name) { this.name = name; }public int getAge() { return age; }public void setAge(int age) { this.age = age; }public String getGender() { return gender;

}public void setGender(String gender) { this.gender = gender; }@Override public String toString() { return "Person{" + "id=" + id + ", name='" + name + '\'' + ", age=" + age + ", gender='" + gender + '\'' + '}'; } }
