1.创建maven工程

添加一个resources文件夹

2.在pom文件导入springboot依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <groupId>com.cwh</groupId>
  <artifactId>webDemo</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>jar</packaging>
  
  <!-- 引入springboot parent-->
  <parent>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-parent</artifactId>
      <version>1.5.10.RELEASE</version>
      <relativePath/>
  </parent>

  <name>webDemo</name>
  <url>http://maven.apache.org</url>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>

  <dependencies>
  
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
    
    <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        
        <!--thymeleaf 模板引擎-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>
    
  </dependencies>
  
</project>

3.在resource文件夹创建application.properties

server.port=8006
logging.level.com.cwh.webDemo=debug

4.在java文件夹下分好包

image.png

在最顶层的包中创建springboot启动类SpringDemoApplication.java

package com.cwh.webDemo;

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

@SpringBootApplication
public class SpringDemoApplication {

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

5.测试springboot是否搭建成功

在控制层写个testController

package com.cwh.webDemo.Controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@RequestMapping("/test")
public class TestController {
    
    @RequestMapping("/sayHello")
    @ResponseBody
    public String sayHello() {
        return "hello";
        
    }

}

启动springDemoApplicationg.java

6.在pom文件添加mybatis，逆向生成mapper及数据库依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

  </parent>

        </plugins>
        
    </build> 
  
</project>

7.在resources文件夹下创建逆向生成的配置文件generatorConfig.xml

<?xml version="1.0" encoding="UTF-8"?>  
<!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">  
<generatorConfiguration>  
    <!-- 数据库驱动包位置 -->  
    <classPathEntry    
        location="E:\apache\repository\mysql\mysql-connector-java\8.0.11\mysql-connector-java-8.0.11.jar" />    
    <context id="Tables" targetRuntime="MyBatis3">  
        <commentGenerator>  
            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->  
            <property name="suppressAllComments" value="true" />  
        </commentGenerator>  
        <!-- 数据库链接URL、用户名、密码 -->  
        <jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"  
            connectionURL="jdbc:mysql://127.0.0.1:3306/shop_system?serverTimezone=GMT" userId="root"  
            password="123456">  
        </jdbcConnection>  
        <javaTypeResolver>  
            <!-- 默认false，把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer， 为 true时把JDBC DECIMAL和NUMERIC类型解析为java.math.BigDecimal -->  
            <property name="forceBigDecimals" value="true" />  
        </javaTypeResolver>  
        <!-- 生成实体类的包名和位置，这里配置将生成的实体类放在com.loan.test.entity这个包下 -->  
        <javaModelGenerator targetPackage="com.cwh.webProject.bean"  
            targetProject="E:\generator">  
            <!-- enableSubPackages:是否让schema作为包的后缀 -->  
            <property name="enableSubPackages" value="true" />  
            <!-- 从数据库返回的值被清理前后的空格 -->  
            <property name="trimStrings" value="true" />  
        </javaModelGenerator>  
        <!-- 生成的SQL映射文件包名和位置，这里配置将生成的SQL映射文件放在com.loan.test.dao.xml这个包下 -->  
        <sqlMapGenerator targetPackage="com.cwh.webProject.mapper"  
            targetProject="E:\generator">  
            <!-- enableSubPackages:是否让schema作为包的后缀 -->  
            <property name="enableSubPackages" value="true" />  
        </sqlMapGenerator>  
        <!-- 生成DAO的包名和位置，这里配置将生成的dao类放在com.loan.test.dao.mapper这个包下 -->  
        <javaClientGenerator type="XMLMAPPER"  
            targetPackage="com.cwh.webProject.dao" targetProject="E:\generator">  
            <!-- enableSubPackages:是否让schema作为包的后缀 -->  
            <property name="enableSubPackages" value="true" />  
        </javaClientGenerator>  
        <!-- 要生成那些表(更改tableName和domainObjectName就可以) -->  
      <!-- <table tableName="user" domainObjectName="User" enableCountByExample="true" enableUpdateByExample="true" enableDeleteByExample="true" enableSelectByExample="true" selectByExampleQueryId="true"></table>       
       <table tableName="client" domainObjectName="Client" enableCountByExample="true" enableUpdateByExample="true" enableDeleteByExample="true" enableSelectByExample="true" selectByExampleQueryId="true"></table>  -->
    </context>  
</generatorConfiguration>

需要对应项目修改生成的包及表名

8.在applicationg.xml配置数据库

server.port=8006

logging.level.com.cwh.webProject=debug

spring.datasource.driverClassName = com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/shop_system?serverTimezone=GMT&useSSL=false
spring.datasource.username=root
spring.datasource.password=123456

mybatis.type-aliases-package=com.cwh.webDemo.Entity
mybatis.mapper-locations: classpath:mapper/*Mapper.xml

后面指定的是mapper.xml文件的位置

9.开始逆向生成

将生成的文件放到项目对应的位置

10.编写server测试能否走通

在启动类中添加dao扫描

package com.cwh.webDemo;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@MapperScan({"com.cwh.webDemo.Dao"})
public class SpringDemoApplication {

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

ClientServer


import java.util.List;

import com.cwh.webDemo.Entity.Client;

public interface ClientServer {
    
    public List<Client> getAll();

}

ClientServerImpl

package com.cwh.webDemo.ServerImpl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.cwh.webDemo.Dao.ClientMapper;
import com.cwh.webDemo.Entity.Client;
import com.cwh.webDemo.Entity.ClientExample;
import com.cwh.webDemo.Server.ClientServer;

@Service
public class ClientServerImpl implements ClientServer {
    
    @Autowired
    private ClientMapper clientMapper;

    public List<Client> getAll() {
        ClientExample clientExample = new ClientExample();
        
        return clientMapper.selectByExample(clientExample);
    }

}

Controller

@RequestMapping("/getClient")
    @ResponseBody
    public void getClient() {
        
         System.out.println(clientServer.getAll());
        
    }
