SpringBoot-整合Mybatis

1. 加入依賴

<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>2.1.1</version>
</dependency>

2. 配置數據源信息

#集成mysql數據庫的配置
spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/community?useUnicode=true&characterEncoding=utf-8
spring.datasource.username=root
spring.datasource.password=root

3. 編寫數據庫的實體類com.july.community.model.User
   屬性與數據庫的字段對齊

public class User{
    private Integer id;
    private String name;
    private String accountId;
    private String token;
    private Long timeCreate;
    private Long timeModified;
    
 public User( String name, String accountId, String token, Long timeCreate, Long timeModified) {
        this.name = name;
        this.accountId = accountId;
        this.token = token;
        this.timeCreate = timeCreate;
        this.timeModified = timeModified;
    }
    public Integer getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getAccountId() {
        return accountId;
    }

    public void setAccountId(String accountId) {
        this.accountId = accountId;
    }

    public String getToken() {
        return token;
    }

    public void setToken(String token) {
        this.token = token;
    }

    public Long getTimeCreate() {
        return timeCreate;
    }

    public void setTimeCreate(Long timeCreate) {
        this.timeCreate = timeCreate;
    }

    public Long getTimeModified() {
        return timeModified;
    }

    public void setTimeModified(Long timeModified) {
        this.timeModified = timeModified;
    }
}

4. 寫Mapper
   com.july.community.mapper.

package com.july.community.mapper;

import com.july.community.model.User;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Mapper;

@Mapper
public interface UserMapper {
    @Insert("insert into tbl_user (name,account_id,token,time_create,time_modified) values (#{name},#{accountId},#{token},#{timeCreate},#{timeModified})")
    void insert(User user);
}

5. 編寫controller中的代碼

 //存入數據庫
            User user = new User(githubUser.getName(),String.valueOf(githubUser.getId()), UUID.randomUUID().toString(),System.currentTimeMillis(),System.currentTimeMillis());
            userMapper.insert(user);

6. 運行測試
   查看數據庫，成功！
