三.集成mybatis步骤

1. 处理依赖pom.xml

    4.0.0

    com.xsy
    aurora_mybatis
    1.0-SNAPSHOT

    
    
        org.springframework.boot
        spring-boot-starter-parent
        2.3.5.RELEASE
    

    
    
        
        1.8
        
        3.8.1
        
        UTF-8
        
        UTF-8
        
        8.0.21
        
        1.2.75
        
        3.5.3
    

    
    

        
            org.springframework.boot
            spring-boot-starter-web
        

        
            org.springframework.boot
            spring-boot-starter-test
            test
        

        
        
            org.projectlombok
            lombok
        

        
        
            com.alibaba
            fastjson
            ${fastjson.version}
        

        
        
            mysql
            mysql-connector-java
            ${mysql-connector-java.version}
            runtime
        

        
        
            org.mybatis.spring.boot
            mybatis-spring-boot-starter
            2.1.2
        

    

    
    
        ${project.name}
        
        
            
                src/main/resources
            
            
                src/main/java
                
                    **/*.xml
                
            
        

        
        
            
                
                
                    org.springframework.boot
                    spring-boot-maven-plugin
                    ${spring.boot.version}
                    
                        true
                        ${project.build.finalName}
                    
                    
                        
                            
                                repackage
                            
                        
                    
                

                
                
                    maven-compiler-plugin
                    ${maven.plugin.version}
                    
                        ${java.version}
                        ${java.version}
                        UTF-8
                        
                            -parameters
                        
                    
                
            
        
    

    
    
        
            aliyun-repos
            https://maven.aliyun.com/nexus/content/groups/public/
            
                false
            
        
    

    
    
        
            aliyun-plugin
            https://maven.aliyun.com/nexus/content/groups/public/
            
                false
            
        
    

2. 处理数据库表

登录mysql数据库，创建表 tianchi_resource，并插入数据

CREATE TABLE `tianchi_resource` (
  `id` bigint NOT NULL COMMENT '自增主键',
  `resource_name` varchar(128) DEFAULT NULL COMMENT '资源名称',
  `resource_path` varchar(255) DEFAULT NULL COMMENT '资源路径',
  `resource_icon` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci DEFAULT NULL COMMENT '资源图标',
  `resource_icon_color` varchar(32) DEFAULT NULL COMMENT '资源图标颜色',
  `resource_describe` varchar(255) DEFAULT NULL COMMENT '资源描述',
  `resource_author` varchar(16) DEFAULT NULL COMMENT '资源作者',
  `resource_type` varchar(16) DEFAULT NULL COMMENT '资源类型',
  `create_time` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  `update_time` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;

-- 插入数据验证
INSERT INTO `aurora`.`tianchi_resource` (`id`, `resource_name`, `resource_path`, `resource_icon`, `resource_icon_color`, `resource_describe`, `resource_author`, `resource_type`, `create_time`, `update_time`) VALUES (1, 'colorUI资源包', 'http://baidu.com', 'url(https://ossweb-img.qq.com/images/lol/web201310/skin/big10001.jpg)', NULL, 'uniapp的ui页面资源包，免费提供,uniapp的ui页面资源包，免费提供,uniapp的ui页面资源包，免费提供', '浅夏的猫', NULL, '2024-01-06 00:50:33', '2024-01-07 23:56:58');

3. 处理配置application.yml

#服务配置
server:
  #端口
  port: 7001

#spring配置
spring:
  #应用配置
  application:
    #应用名
    name: aurora_mybatis

  #数据源配置
  datasource:
    #驱动
    driver-class-name: com.mysql.cj.jdbc.Driver
    #连接地址
    url: jdbc:mysql://127.0.0.1:3306/aurora?serverTimezone=UTC&characterEncoding=UTF-8&useUnicode=true&useSSL=false&tinyInt1isBit=false&allowPublicKeyRetrieval=true
    #数据库用户
    username: root
    #数据库密码
    password: yourpassword

#mybatis配置
mybatis:
  #mapper.xml文件扫描路径
  mapper-locations: classpath*:mapper/*Mapper.xml
  #实体类扫描路径，配置这个以后mapper,xml里面写的实体类不需要全路径
  type-aliases-package: com.aurora.entity
  #mybatis拓展配置
  configuration:
    #设置下划线自动转换为大写字母
    map-underscore-to-camel-case: true

4.创建对应的类

（1）主启动类

tips：Application.class 类 springboot程序启动必备

package com.aurora;

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

/**
 * @author 浅夏的猫
 * @description 主启动类
 * @date 22:46 2024/1/13
 */
@SpringBootApplication
@MapperScan("com.aurora.mapper")
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

（2）实体类

tips：ResourceEntity.class 类 创建与数据库表对应的实体类，后续映射需要使用

package com.aurora.entity;

import com.fasterxml.jackson.annotation.JsonFormat;

import java.io.Serializable;
import java.util.Date;


/**
 * @author 浅夏的猫
 * @description 资源实体类
 * @date 22:42 2024/1/13
 */
public class ResourceEntity implements Serializable {

    private static final long serialVersionUID = 1L;

    //资源id
    private Long id;
    //资源名称
    private String resourceName;
    //资源路径
    private String resourcePath;
    //资源图标
    private String resourceIcon;
    //资源图标颜色
    private String resourceIconColor;
    //资源描述
    private String resourceDescribe;
    //资源类型
    private String resourceType;
    //资源作者
    private String resourceAuthor;

    //资源创建时间
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
    private Date createTime;

    //资源更新时间
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
    private Date updateTime;

    //查询结束时间
    private Date endTime;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getResourceName() {
        return resourceName;
    }

    public void setResourceName(String resourceName) {
        this.resourceName = resourceName;
    }

    public String getResourcePath() {
        return resourcePath;
    }

    public void setResourcePath(String resourcePath) {
        this.resourcePath = resourcePath;
    }

    public String getResourceIcon() {
        return resourceIcon;
    }

    public void setResourceIcon(String resourceIcon) {
        this.resourceIcon = resourceIcon;
    }

    public String getResourceIconColor() {
        return resourceIconColor;
    }

    public void setResourceIconColor(String resourceIconColor) {
        this.resourceIconColor = resourceIconColor;
    }

    public String getResourceDescribe() {
        return resourceDescribe;
    }

    public void setResourceDescribe(String resourceDescribe) {
        this.resourceDescribe = resourceDescribe;
    }

    public String getResourceType() {
        return resourceType;
    }

    public void setResourceType(String resourceType) {
        this.resourceType = resourceType;
    }

    public String getResourceAuthor() {
        return resourceAuthor;
    }

    public void setResourceAuthor(String resourceAuthor) {
        this.resourceAuthor = resourceAuthor;
    }

    public Date getCreateTime() {
        return createTime;
    }

    public void setCreateTime(Date createTime) {
        this.createTime = createTime;
    }

    public Date getUpdateTime() {
        return updateTime;
    }

    public void setUpdateTime(Date updateTime) {
        this.updateTime = updateTime;
    }

    public Date getEndTime() {
        return endTime;
    }

    public void setEndTime(Date endTime) {
        this.endTime = endTime;
    }

    @Override
    public String toString() {
        return "ResourceEntity{" +
                "id=" + id +
                ", resourceName='" + resourceName + '\'' +
                ", resourcePath='" + resourcePath + '\'' +
                ", resourceIcon='" + resourceIcon + '\'' +
                ", resourceIconColor='" + resourceIconColor + '\'' +
                ", resourceDescribe='" + resourceDescribe + '\'' +
                ", resourceType='" + resourceType + '\'' +
                ", resourceAuthor='" + resourceAuthor + '\'' +
                ", createTime=" + createTime +
                ", updateTime=" + updateTime +
                ", endTime=" + endTime +
                '}';
    }
}

（3）创建映射类

tips：映射类主要用于编写操作sql的接口方法

package com.aurora.mapper;

import com.aurora.entity.ResourceEntity;
import org.apache.ibatis.annotations.Mapper;

import java.util.List;

/**
 * @author 浅夏的猫
 * @description 资源mapper操作类
 * @date 22:45 2024/1/13
 */
@Mapper
public interface ResourceMapper {

    /**
     * @return java.util.List
     * @description
     * @author 浅夏的猫
     * @datetime 23:19 2024/1/13
     */
    List list();
}

（4）创建sql映射文件

tips： 每一个映射类对应一个mapper映射文件，在resources的mapper包下写映射文件

    
        select * from tianchi_resource
    

（5）创建控制类

tips： 控制类用于浏览器或前端访问使用

package com.aurora.controller;

import com.aurora.entity.ResourceEntity;
import com.aurora.mapper.ResourceMapper;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.annotation.Resource;
import java.util.List;

/**
 * @author 浅夏的猫
 * @description 资源controller
 * @date 22:38 2024/1/13
 */
@RestController
@RequestMapping("/resource")
public class ResourceController {

    @Resource
    private ResourceMapper resourceMapper;

    /**
     * @return java.util.List
     * @description 查询全部资源数据列表
     * @author 浅夏的猫
     * @date 22:40 2024/1/13
     */
    @RequestMapping("/list")
    public List list() {
        return resourceMapper.list();
    }
}

（5）启动应用，控制台访问

tips： 访问地址http://localhost:7001/resource/list
