按照狂神说的SSM框架教程初步尝试整合了SSM

为了方便以后查看和学习所以注解都带上了

做个记录,这周末结束之前要自己实现SSM整合

外加入门JavaScript

首先配置pom.xml,导入web支持

建立一个实体类

Books
package top.moesy.pojo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@AllArgsConstructor
@Data
@NoArgsConstructor
public class Books {
    private int bookID;
    private String bookName;
    private int bookCounts;
    private String detail;

}

配置jdbc

datebase.properties
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?
useSSL=true&useUnicode=true&characterEncoding=utf8
jdbc.username=root
