 一、SSMP整合案例

1.1 项目搭建

1.1.1 模块搭建

①勾上需要使用的技术

②需要手动导入的依赖 

        
        
            com.baomidou
            mybatis-plus-boot-starter
            3.5.1
        

        
        
            com.alibaba
            druid-spring-boot-starter
            1.2.11
        

        
        
            org.projectlombok
            lombok
        

③修改配置文件为yml格式，并且设置端口号

server:
  port: 80

1.2 实体类开发

package com.learn.domain;

import lombok.Data;

/**
 * @author 咕咕猫
 * @version 1.0
 */
@Data
public class Book {
    private Integer id;
    private String type;
    private String name;
    private String description;

}

1.3 数据层开发

1.3.1 数据层开发——分页功能

    @Test
    void testGetPage(){
        IPage page = new Page(1,5);
        bookDao.selectPage(page,null);
        System.out.println(page.getCurrent());
        System.out.println(page.getSize());
        System.out.println(page.getTotal());
        System.out.println(page.getPages());
        System.out.println(page.getRecords());
    }

package com.learn.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(){
        //1.定义Mp拦截器
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        //2.添加具体的拦截器
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor());
        return interceptor;
    }

}

1.3.2 数据层开发——条件查询功能

1.4 业务层开发

1.4.1 业务层快速开发

1.5 表现层开发

package com.learn.controller;

import com.baomidou.mybatisplus.core.metadata.IPage;
import com.learn.domain.Book;
import com.learn.service.IBookService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.List;

/**
 * @author 咕咕猫
 * @version 1.0
 */
//@RestController
@RequestMapping("/books")
public class BookController2 {

    @Autowired
    private IBookService bookService;

    @GetMapping
    public List getAll() {
        return bookService.list();
    }

    @PostMapping
    public Boolean save(@RequestBody Book book) {
        return bookService.save(book);
    }

    @PutMapping
    public Boolean update(@RequestBody Book book) {
        return bookService.modify(book);
    }

    @DeleteMapping("{id}")
    public Boolean delete(@PathVariable Integer id) {
        return bookService.delete(id);
    }

    @GetMapping("{id}")
    public Book getById(@PathVariable Integer id) {
        return bookService.getById(id);
    }

    @GetMapping("{currentPage}/{pageSize}")
    public IPage getPage(@PathVariable int currentPage, int pageSize) {
        return bookService.getPage(currentPage,pageSize);
    }

}

1.5.1 表现层消息一致性处理

 

package com.learn.controller;

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

import java.util.List;

/**
 * @author 咕咕猫
 * @version 1.0
 */
@RestController
@RequestMapping("/books")
public class BookController {

    @Autowired
    private IBookService bookService;

    @GetMapping
    public R getAll() {
        return new R(true, bookService.list());
    }

    @PostMapping
    public R save(@RequestBody Book book) {
//        R r = new R();
//        boolean flag = bookService.save(book);
//        r.setFlag(flag);
        return new R(bookService.save(book));
    }

    @PutMapping
    public R update(@RequestBody Book book) {
        return new R(bookService.modify(book));
    }

    @DeleteMapping("{id}")
    public R delete(@PathVariable Integer id) {
        return new R(bookService.delete(id));
    }

    @GetMapping("{id}")
    public R getById(@PathVariable Integer id) {
        return new R(true, bookService.getById(id));

    }

    @GetMapping("{currentPage}/{pageSize}")
    public R getPage(@PathVariable int currentPage, int pageSize) {
        return new R(true, bookService.getPage(currentPage, pageSize));
    }

}
