Spring LOC和DI

Spring LOC和DI
1、Spring jar包下载
https://repo.spring.io/libs-release-local/org/springframework/spring/
创建lib目录，导入jar包，并配置为项目的Library
在这里插入图片描述

2、创建com.gx.model.User类，用于演示IOC和DI
package com.gx.model;import java.io.Serializable;
public class User implements Serializable {
private String name;
public int age;
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;
}
@Override
public String toString() {
return “User{” +
“name='” &#
