1.导入依赖

2.创建实体类

3.写dao层接口

4.写mybatis核心配置文件和接口配置文件

5.用spring整合Mybatis层也就是Dao层

6.spring整合Service层

7.spring整合Conteoller层

8.添加web支持

9.完整的目录结构

1.导入依赖

junitjunit4.12mysqlmysql-connector-java5.1.47com.mchangec3p00.9.5.2

javax.servletservlet-api2.5javax.servlet.jspjsp-api2.2javax.servletjstl1.2

org.mybatismybatis3.5.2org.mybatismybatis-spring2.0.2

org.springframeworkspring-webmvc5.1.9.RELEASEorg.springframeworkspring-jdbc5.1.9.RELEASE

org.springframeworkspring-context5.1.9.RELEASE

com.fasterxml.jackson.corejackson-databind2.12.1com.alibabadruid-spring-boot-starter1.1.10

src/main/java**/*.properties**/*.xmlfalsesrc/main/resources**/*.properties**/*.xmlfalse

2.创建实体类

package pojo;

public class books {private int bookId;private String bookName;private int bookCounts;private String detail;

public books(int bookId, String bookName, int bookCounts, String detail) {this.bookId = bookId;this.bookName = bookName;this.bookCounts = bookCounts;this.detail = detail;}

public books() {}

public int getBookId() {return bookId;}

public void setBookId(int bookId) {this.bookId = bookId;}

public String getBookName() {return bookName;}

public void setBookName(String bookName) {this.bookName = bookName;}

public int getBookCounts() {return bookCounts;}

public void setBookCounts(int bookCounts) {this.bookCounts = bookCounts;}

public String getDetail() {return detail;}

public void setDetail(String detail) {this.detail = detail;}}

3.写dao层接口

这里暂时只有一个方法package Dao;

import pojo.books;

import java.util.List;

public interface BooksMapper {List selectbooks();}

4.写mybatis核心配置文件和接口配置文件

这个是接口配置文件

mybatis核心配置文件

5.用spring整合Mybatis层也就是Dao层

这个是spring整合Mybatis的xml文件

数据库配置文件，这里你们改一下数据库就OKjdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/ssmbuild jdbc.username=root jdbc.password=root

6.spring整合Service层

写接口和实现类package Service;

import org.springframework.stereotype.Service;import pojo.books;

import java.util.List;

public interface BooksService {List selectbooks();}实现类@Service public class BooksServicelmpl implements BooksService{/*这里是把Dao的接口引进来了因为Service层调用Dao层*/@Autowired private BooksMapper booksMapper;public void setBooksMapper(BooksMapper booksMapper) {this.booksMapper = booksMapper;}@Override public List selectbooks() {return booksMapper.selectbooks();}}写spring配置文件

关联spring配置文件，我们写个总的配置文件到进去就ok

7.spring整合Conteoller层

写Controller的类@RestController public class bookController {@Autowired private BooksService booksService;public void setBooksService(BooksService booksService) {this.booksService = booksService;}@RequestMapping("/books") public List selectbooks(){List list = booksService.selectbooks();return list;}}把三个配置文件关联

8.添加web支持

写web.xml文件里面都是死的

springmvcorg.springframework.web.servlet.DispatcherServletcontextConfigLocationclasspath:applicationContext.xml1springmvc/

encodingFilterorg.springframework.web.filter.CharacterEncodingFilterencodingutf-8encodingFilter/*

15

创建一个lib包把依赖导进去

添加工件测试

9.完整的目录结构
