第一个SSM整个框架完成增删改查的项目（里面的配置文件可以复用）

SSM框架整合的配置

建立和数据库对应的实体类pojo

1.建议自己表名改成首字母大写作为名字

2.要偷懒的记得导入lombok，

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

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

在dao层建立查询数据库的方法，一个接口类和一个接口对应的xml

接口类就注意我们调用的参数和放回的结果集

xml里面好好设计SQL

BookMapper接口类 (要是有参数，都给它规定上自己的名字，在mybatis-config里面规定了别名，类型才可以简写)

package com.mac.dao;

import com.mac.pojo.Books;
import org.apache.ibatis.annotations.Param;

import java.util.List;

public interface BookMapper {

    //增加一本书
    int addBook(Books books);

    //删除一本书
    int deleteBookById(@Param("id") int id);

    //更新一本书
    int apdateBook(Books books);

    //查询一本书
    Books queryBookById(@Param("id") int id);

    //查询全部的书
    List<Books> queryAllBook();

    //搜索框查询功能
    List<Books> queryBookByName(@Param("BookName") String BookName);

}

BookMapper.xml

（在这里编写Mapper接口方法中对应的SQL查询语句，可以多结合动态SQL来优化）

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="com.mac.dao.BookMapper">
    <insert id="addBook" parameterType="books">
        insert into ssmbuild.books(bookID,bookName, bookCounts, detail)
        VALUES (#{bookID},#{bookName},#{bookCounts},#{detail})
    </insert>

    <delete id="deleteBookById" parameterType="int">
        delete from ssmbuild.books where bookID=#{id}
    </delete>

    <update id="apdateBook" parameterType="books">
        update ssmbuild.books
        set  bookName=#{bookName},bookCounts=#{bookCounts},detail=#{detail}
        where bookID=#{bookID};
    </update>

    <select id="queryBookById" parameterType="int" resultType="books">
        select * from ssmbuild.books where bookID=#{id}
    </select>

    <select id="queryAllBook" resultType="books">
        select * from ssmbuild.books
    </select>

    <select id="queryBookByName" resultType="books">
        select * from ssmbuild.books
            <where>
                <if test="BookName != null">
                    bookName like #{BookName}
                </if>
            </where>
    </select>

</mapper>

service层的功能就是去调用dao层，有一个接口类和一个实现类

1.接口的方法就和dao层的接口是基本一致的

2.实现类去继承这个接口，这个实现类的功能就很明确，就是去直接调用dao已经写好的对应方法，可能会有一点小小的变化

BookService:

package com.mac.service;

import com.mac.pojo.Books;
import org.apache.ibatis.annotations.Param;

import java.util.List;

public interface BookService {
    //增加一本书
    int addBook(Books books);

    //删除一本书
    int deleteBookById(int id);

    //更新一本书
    int apdateBook(Books books);

    //查询一本书
    Books queryBook(int id);

    //查询全部的书
    List<Books> queryAllBook();

    //搜索框查询功能
    List<Books> queryBookByName(String BookName);
}

BookServiceImpl

package com.mac.service;

import com.mac.dao.BookMapper;
import com.mac.pojo.Books;

import java.util.List;

public class BookServiceImpl implements BookService {

    //service掉dao层；组合进来
    private BookMapper bookMapper;
    public void setBookMapper(BookMapper bookMapper) {
        this.bookMapper = bookMapper;
    }

    public int addBook(Books books) {
        return bookMapper.addBook(books);
    }

    public int deleteBookById(int id) {
        return bookMapper.deleteBookById(id);
    }

    public int apdateBook(Books books) {
        return bookMapper.apdateBook(books);
    }

    public Books queryBook(int id) {
        return bookMapper.queryBookById(id);
    }

    public List<Books> queryAllBook() {
        return bookMapper.queryAllBook();
    }

    public List<Books> queryBookByName(String BookName) {
        String s="%"+BookName+"%";
        List<Books> list = bookMapper.queryBookByName(s);
        return list;
    }


}

开始编写controller层，controller就是调用service层的方法，并且通过前端的name拿到数据，已经通过Model封装我们在数据库底层查到的数据去放回给前端页面进行展示

1.每个方法都对应一个字节的URL地址，

有的是用来跳转页面的方法，有的是用来做数据操作的，注意区分

BookController

package com.mac.controller;

import com.mac.pojo.Books;
import com.mac.service.BookService;
import com.mac.service.BookServiceImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.ArrayList;
import java.util.List;

@Controller
@RequestMapping("/book")
public class BookController {
    //controller掉service层    必须的操作
    @Autowired
    @Qualifier("BookServiceImpl")
    private BookService bookService =new BookServiceImpl();


    //查询所有的书籍，并且放回到书籍展示页面
    @RequestMapping("/allBook")
    public String list(Model model){
        List<Books> list = bookService.queryAllBook();
        model.addAttribute("list",list);
        return "allBook";
    }

    //跳转到增加书籍页面
    @RequestMapping("/toAddBook")
    public String toAddpaper(){
        return "addBook";
    }

    //添加书籍的请求
    @RequestMapping("/addBook")

这是我第一个前端后端一起写的代码，但是是按照视频学来的，记录一下，

2022/4/27,还有2天五一放假了
