SSMP图书管理系统

1. 项目结构

2. 页面展示

3. 使用技术

SpringBoot + MybatisPlus + SqlServer

4. 数据准备

create table tbl_book(
id int primary key identity(1,1),
type varchar(20)  COLLATE Latin1_General_100_BIN2_UTF8 NULL,
name varchar(50)  COLLATE Latin1_General_100_BIN2_UTF8 NULL,
description varchar(255)  COLLATE Latin1_General_100_BIN2_UTF8 NULL
)

insert into tbl_book(type,name,description) values('计算机理论','spring实战第五版','Spring入门经典教程')
insert into tbl_book(type,name,description) values('计算机理论','Java编程思想','Java学习必读经典')
insert into tbl_book(type,name,description) values('计算机理论','深入理解java虚拟机','5个维度全面剖析JVM')

7. Dao层

package com.itheima.dao;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.itheima.domain.Book;
import org.apache.ibatis.annotations.Mapper;

@Mapper
public interface BookDao extends BaseMapper<Book> {


}

8. Book实体类

//lombok
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Book {
    private Integer id;
    private String type;
    private String name;
    private String description;

}

9. Service层

BookServiceImpl

package com.itheima.service.impl;
import com.baomidou.mybatisplus.core.metadata.IPage;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.itheima.dao.BookDao;
import com.itheima.domain.Book;
import com.itheima.service.BookService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class BookServiceImpl implements BookService {
    @Autowired
    BookDao bookDao;

    @Override
    public Boolean save(Book book) {
        return bookDao.insert(book)>0;
    }

    @Override
    public Boolean update(Book book) {
        return bookDao.updateById(book)>0;
    }

    @Override
    public Boolean delete(Integer id) {
        return bookDao.deleteById(id)>0;
    }

    @Override
    public Book getById(Integer id) {
        return bookDao.selectById(id);
    }

    @Override
    public List<Book> getAll() {
        return bookDao.selectList(null);
    }

    @Override
    public IPage<Book> getPage(int currentPage, int pageSize) {
        IPage<Book> page=new Page<>(currentPage,pageSize);
        return bookDao.selectPage(page,null);
    }
}

IBookServiceImpl

package com.itheima.service.impl;

import com.baomidou.mybatisplus.core.conditions.query.LambdaQueryWrapper;
import com.baomidou.mybatisplus.core.metadata.IPage;
import com.baomidou.mybatisplus.extension.plugins.pagination.Page;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.itheima.dao.BookDao;
import com.itheima.domain.Book;
import com.itheima.service.IBookService;
import org.apache.logging.log4j.util.Strings;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class IBookServiceImpl extends ServiceImpl<BookDao, Book> implements IBookService {
    @Autowired
    private BookDao bookDao;

    @Override
    public IPage<Book> getPage(int currentPage, int pageSize) {
        IPage page=new Page(currentPage,pageSize);
        return bookDao.selectPage(page,null);
    }

    @Override
    public IPage<Book> getPage(int currentPage, int pageSize,Book book) {
        LambdaQueryWrapper<Book> lqw=new LambdaQueryWrapper<Book>();
        lqw.like(Strings.isNotEmpty(book.getType()),Book::getType,book.getType());
        lqw.like(Strings.isNotEmpty(book.getDescription()),Book::getDescription,book.getDescription());
        lqw.like(Strings.isNotEmpty(book.getName()),Book::getName,book.getName());
        IPage<Book> page=new Page(currentPage,pageSize);
        bookDao.selectPage(page,lqw);
        return page;
    }
}

BookService接口

package com.itheima.service;
import com.baomidou.mybatisplus.core.metadata.IPage;
import com.itheima.domain.Book;
import java.util.List;

public interface BookService {
    Boolean save(Book book);
    Boolean update(Book book);
    Boolean delete(Integer id);
    Book getById(Integer id);
    List<Book> getAll();
    IPage<Book> getPage(int currentPage, int pageSize);
}

IBookService接口

package com.itheima.service;
import com.baomidou.mybatisplus.core.metadata.IPage;
import com.baomidou.mybatisplus.extension.service.IService;
import com.itheima.domain.Book;

public interface IBookService extends IService<Book> {
    IPage<Book> getPage(int currentPage, int pageSize, Book book);
    IPage<Book> getPage(int currentPage, int pageSize);
}

10. Controller层

ProjectExceptionAdvice

package com.itheima.controller.utils;


import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RestControllerAdvice;

//作为springmvc的异常处理器
//@ControllerAdvice
@RestControllerAdvice
public class ProjectExceptionAdvice {
     //拦截所有的异常信息
     @ExceptionHandler(Exception.class)
     public Result doException(Exception e){
        //记录日志
        //通知运维
        //通知开发
        e.printStackTrace();
        return new Result(false,"服务器故障，请稍后再试");
     }
}

Result

package com.itheima.controller.utils;

import lombok.Data;

@Data
public class Result {
    private Boolean flag;
    private Object data;
    private String msg;

    public Result(Boolean flag){
        this.flag=flag;
    }

    public Result() {
    }

    public Result(Boolean flag, Object data) {
        this.flag = flag;
        this.data = data;
    }

    public Result(Boolean flag,String msg) {
        this.flag = flag;
        this.msg = msg;
    }

}

BookController

package com.itheima.controller;
import com.baomidou.mybatisplus.core.metadata.IPage;
import com.itheima.controller.utils.Result;
import com.itheima.domain.Book;
import com.itheima.service.IBookService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

@RestController
@RequestMapping("/books")
public class BookController {

    @Autowired
    private IBookService bookService;
    @GetMapping
    public Result getAll(){
        return new Result(true,bookService.list());
    }
    @GetMapping("{id}")
    public Result getById(@PathVariable Integer id){
        return new Result(true,bookService.getById(id));
    }
    @PostMapping
    public Result save(@RequestBody Book book){
        Boolean flag=bookService.save(book);
        return new Result(flag,flag?"添加成功^_^":"添加失败-_-!");
    }
    @PutMapping
    public Result update(@RequestBody Book book){
        return new Result(bookService.updateById(book));
    }
    @DeleteMapping("{id}")
    public Result delete(@PathVariable  Integer id){
        return new Result(bookService.removeById(id));
    }
   @GetMapping("{currentPage}/{pageSize}")
   public Result getPage(@PathVariable int currentPage,@PathVariable int pageSize,Book book){
       System.out.println("参数===>"+book);
       IPage<Book> page=bookService.getPage(currentPage, pageSize,book);
       //如果当前页码值大于总页码值,那么重新执行查询操作,使得最大页码值作为当前页码值
       if(currentPage>page.getPages()){
           page= bookService.getPage((int) page.getPages(), pageSize,book);
       }
       return new Result(true,page);
   }
}

11. 分页配置类

MPConfig

package com.itheima.config;

import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class MPConfig {
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor(){
        MybatisPlusInterceptor interceptor=new MybatisPlusInterceptor();
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor());
        return interceptor;
    }
}

12. SpringBoot启动类

SSMPApplication

package com.itheima;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SSMPApplication {

    public static void main(String[] args) {
        SpringApplication.run(SSMPApplication.class, args);
    }

}
