java后端开发-搭建springboot框架

一、开发工具idea

二、用开发工具创建一个springboot

用的是maven管理依赖

三、加载依赖

也可以创建玩了后在pom.xml中配置，本人习惯用pom—

选择项目本地保存路径，然后 Finish

四、创建完成，开始配置

安装插件 Lombok、还有一个是方便mybatis的

五、配置pom.xml依赖

这是我以前的demo加载的，也可以自己去依赖仓库中找你需要的依赖

        </dependency>

六、配置maven

先找到本地maven仓库

设置settings.xml 没有就创建这个文件 下载依赖包就优先从阿里云下载

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

    <!-- Apache Maven 配置 -->
    <pluginGroups/>
    <proxies/>
    
    <!-- 阿里云镜像 https://maven.aliyun.com/repository/public/-->
    <mirrors>
        <mirror>
            <id>alimaven</id>
            <name>aliyun maven</name>
            <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
            <mirrorOf>central</mirrorOf>
        </mirror>
    </mirrors>

    <!-- 配置: java8, 先从阿里云下载, 没有再去私服下载  -->
    <!-- 20190929 hepengju 测试结果: 影响下载顺序的是profiles标签的配置顺序(后面配置的ali仓库先下载), 而不是activeProfiles的顺序 -->
    <profiles>
        <!-- 全局JDK1.8配置 -->
        <profile>
            <id>jdk1.8</id>
            <activation>
                <activeByDefault>true</activeByDefault>

            </activation>
            <properties>
                <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
                <maven.compiler.source>1.8</maven.compiler.source>
                <maven.compiler.target>1.8</maven.compiler.target>
                <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
            </properties>
        </profile>
        <!-- 阿里云配置: 提高国内的jar包下载速度 -->
        <profile>
            <id>ali</id>
            <repositories>
                <repository>
                    <id>alimaven</id>
                    <name>aliyun maven</name>
                    <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
                    <releases>
                        <enabled>true</enabled>
                    </releases>
                    <snapshots>
                        <enabled>true</enabled>
                    </snapshots>
                </repository>
            </repositories>
            <pluginRepositories>
                <pluginRepository>
                    <id>alimaven</id>
                    <name>aliyun maven</name>
                    <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
                </pluginRepository>
            </pluginRepositories>
        </profile>

    </profiles>
    
    <!-- 激活配置 --> 
    <activeProfiles>
        <activeProfile>jdk1.8</activeProfile>
        <activeProfile>dev</activeProfile>
        <activeProfile>ali</activeProfile>
    </activeProfiles>
</settings>

七、配置application.yml

找到resources文件下的 application 配置文件 修改为 application.yml
我这里配置了本地的数据库连接配置、redis连接配置、mybatis-plus配置

#端口
server:
  port: 9999

spring :
  #数据库
  datasource:
    url: jdbc:mysql://localhost:3306/zhaomaolin?serverTimezone=UTC&useunicode=true&characterEncoding=utf8
    username: root
    password: root
    driver-class-name: com.mysql.cj.jdbc.Driver

  #redis配置
  redis:
    #Redis服务器连接地址
    host: 127.0.0.1
    #Redis服务器连接端口
    port: 6379
    #Redis服务器连接密码（默认为空）
    password:
    jedis:
      pool:
        #连接池最大连接数（使用负值表示没有限制）
        max-active: 8
        #连接池最大阻塞等待时间（使用负值表示没有限制）
        max-wait: -1
        #连接池中的最大空闲连接
        max-idle: 8
        #连接池中的最小空闲连接
        min-idle: 0
        #连接超时时间（毫秒）
        timeout: 30000

#持久层框架配置
mybatis-plus:
  global-config:
    db-config:
      id-type: auto
      field-strategy: not_empty
      #驼峰下划线转换
      column-underline: true
      #逻辑删除配置
      logic-delete-value: 0
      logic-not-delete-value: 1
      db-type: mysql
    refresh: false
  configuration:
    map-underscore-to-camel-case: true
    cache-enabled: false
  mapper-locations: classpath:mapper/**/*Mapper.xml

八、mybatis-plus配置类

import com.baomidou.mybatisplus.plugins.PaginationInterceptor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.transaction.annotation.EnableTransactionManagement;

/**
 * 分页配置类
 * @author zhaomaolin
 */
@EnableTransactionManagement
@Configuration
public class MybatisPlusConfig {
     
 
     @Bean
     public PaginationInterceptor paginationInterceptor() {
     

        return new PaginationInterceptor();
     }
}

九、配置完成，开始敲代码了

创建用户表

CREATE TABLE `zhao_user` (
  `user_id` int(11) NOT NULL AUTO_INCREMENT COMMENT '主键',
  `user_name` varchar(36) NOT NULL COMMENT '名字',
  `user_nice` varchar(36) DEFAULT NULL COMMENT '昵称',
  `user_phone` varchar(11) NOT NULL COMMENT '电话',
  `user_password` varchar(64) NOT NULL COMMENT '密码',
  `user_account` varchar(36) NOT NULL COMMENT '登录账号',
  `user_gender` varchar(3) DEFAULT NULL COMMENT '性别',
  `remark` varchar(255) DEFAULT NULL COMMENT '备注',
  `is_active` tinyint(4) DEFAULT '1' COMMENT '是否启用 0禁用，1启用',
  `is_delete` tinyint(4) DEFAULT '1' COMMENT '是否删除 0删除，1正常',
  `create_time` datetime DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
  `create_person_id` int(11) DEFAULT NULL COMMENT '创建者id',
  `update_time` datetime DEFAULT NULL COMMENT '修改时间',
  `update_person_id` int(11) DEFAULT NULL COMMENT '修改者id',
  `delete_time` datetime DEFAULT NULL COMMENT '删除时间',
  `delete_person_id` int(11) DEFAULT NULL COMMENT '删除者id',
  PRIMARY KEY (`user_id`) USING BTREE,
  UNIQUE KEY `account` (`user_account`) USING HASH COMMENT '唯一登录账号'
) ENGINE=MyISAM AUTO_INCREMENT=9 DEFAULT CHARSET=utf8 COMMENT='用户表';

实体类基类配置

import java.io.Serializable;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;
import com.fasterxml.jackson.annotation.JsonFormat;
import lombok.Data;
import org.springframework.format.annotation.DateTimeFormat;

/**
 * Entity基类配置
 *
 * @author zhaomaolin
 */
@Data
public class BaseEntityConfig implements Serializable {
     

    private static final long serialVersionUID = 1L;

    //是否删除
    private Boolean isDelete;

    //是否启用
    private Boolean isActive;

    //备注
    private String remark;

    //创建时间
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    private Date createTime;

    //创建者id
    private Integer createPersonId;

    //更新时间
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    private Date updateTime;

    //更新者id
    private Integer updatePersonId;

    //删除时间
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    private Date deleteTime;

    //删除者
    private Integer deletePersonId;

    //请求参数
    private Map<String, Object> params;
    public Map<String, Object> getParams() {
     
        if (params == null) {
     
            params = new HashMap<>();
        }
        return params;
    }
    public void setParams(Map<String, Object> params) {
     
        this.params = params;
    }
}

创建实体类

import com.zp.vip.centre.config.BaseEntityConfig;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;

import javax.validation.constraints.NotNull;

@Data
public class ZhaoUser extends BaseEntityConfig{
     

    /*主键*/
    @ApiModelProperty(value = "主键" )
    private Integer userId;

    /*名字*/
    @NotNull(message = "参数名字不能为空")
    @ApiModelProperty(value = "名字" )
    private String userName;

    /*昵称*/
    @ApiModelProperty(value = "昵称" )
    private String userNice;

    /*电话*/
    @ApiModelProperty(value = "电话" )
    private String userPhone;

    /*密码*/
    @ApiModelProperty(value = "密码" )
    private String userPassword;

    /*登录账号*/
    @ApiModelProperty(value = "登录账号" )
    private String userAccount;

    /*性别*/
    @ApiModelProperty(value = "性别" )
    private String userGender;

}

创建接收类和返回类

import lombok.Data;


@Data
public class ZhaoUserDTO extends ZhaoUser{
     

}

import lombok.Data;

@Data
public class ZhaoUserVO extends ZhaoUser{
     
    
}

创建控制器

import com.baomidou.mybatisplus.plugins.Page;
import com.zp.vip.centre.domain.dto.PostIds;
import com.zp.vip.centre.domain.vo.BaseResponse;
import com.zp.vip.extend.entity.zhao.user.ZhaoUser;

import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.multipart.MultipartFile;

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

/**

//@Controller
@RestController//(前后端分离使用)
@RequestMapping("/user")
public class ZhaoUserController {
     

    @Resource
    private IZhaoUserService zhaoUserService;

    /**
     * 用户详情
     * @param zhaoUser
     * @return
     */
    @GetMapping("/info")
    public BaseResponse info(ZhaoUserDTO zhaoUser) {
     
        ZhaoUser info = zhaoUserService.selectInfo(zhaoUser);
        return BaseResponse.success(info);
    }

    /**
     * 用户列表
     * @param page
     * @param zhaoUser
     * @return
     */
    @GetMapping("/list")
    public Page<ZhaoUser> list(Page page,ZhaoUserDTO zhaoUser) {
     
        Page<ZhaoUser> list = zhaoUserService.selectUserPage(page,zhaoUser);
        return list;
    }

    /**
     * 添加用户
     * @param zhaoUser
     * @return
     */
    @PostMapping("/add")
    public BaseResponse add(@Validated @RequestBody ZhaoUser zhaoUser) {
     
        boolean res = zhaoUserService.addUser(zhaoUser);
        return BaseResponse.success(res);
    }

    /**
     * 修改用户
     * @param zhaoUser
     * @return
     */
    @PostMapping("/edit")
    public BaseResponse edit(@RequestBody ZhaoUserDTO zhaoUser) {
     
        boolean res = zhaoUserService.editUserById(zhaoUser);
        return BaseResponse.success(res);
    }

    /**
     * 删除用户
     * @param zhaoUser
     * @return
     */
    @PostMapping("/del")
    public BaseResponse del(@RequestBody ZhaoUserDTO zhaoUser) {
     
        try{
     
            zhaoUserService.delUserById(zhaoUser);
        }catch (Exception e){
     
            return BaseResponse.error(e.getMessage());
        }
        return BaseResponse.success();
    }

    /**
     * 批量删除用户
     * @param ids
     * @return
     */
    @PostMapping("/deletes")
    public BaseResponse deletes(@RequestBody PostIds ids) {
     
        int res = 0;

        try{
     
            res = zhaoUserService.delUserByIds(ids.getIds());
        }catch (Exception e){
     
            return BaseResponse.error(e.getMessage());
        }

        return BaseResponse.success(res);
    }

    /**
     * 启用禁用
     * @param zhaoUser
     * @return
     */
    @PostMapping("/active")
    public BaseResponse active(@RequestBody ZhaoUserDTO zhaoUser) {
     
        boolean res = zhaoUserService.activeUserByIds(zhaoUser);
        return BaseResponse.success(res);
    }
}

创建业务逻辑层接口类

import com.baomidou.mybatisplus.plugins.Page;
import com.zp.vip.extend.entity.zhao.user.ZhaoUser;
import com.zp.vip.extend.entity.zhao.user.ZhaoUserDTO;
import com.zp.vip.extend.entity.zhao.user.ZhaoUserVO;

import java.util.List;

public interface IZhaoUserService {
     
    //详情
    ZhaoUserVO selectInfo(ZhaoUserDTO zhaoUser);
    //列表
    Page<ZhaoUserVO> selectUserPage(Page<ZhaoUserVO> page, ZhaoUserDTO zhaoUser);
    //添加
    boolean addUser(ZhaoUser zhaoUser);
    //修改
    boolean editUserById(ZhaoUserDTO zhaoUser);
    //删除
    boolean delUserById(ZhaoUserDTO zhaoUser)throws Exception;
    //批量删除用户
    int delUserByIds(List<Integer> ids)throws Exception;
    //启用禁用
    boolean activeUserByIds(ZhaoUserDTO zhaoUser);
}

创建业务逻辑层实现类

创建mybatis映射接口类

import com.baomidou.mybatisplus.mapper.BaseMapper;
import com.baomidou.mybatisplus.plugins.pagination.Pagination;
import com.zp.vip.extend.entity.zhao.user.ZhaoUser;
import com.zp.vip.extend.entity.zhao.user.ZhaoUserDTO;
import com.zp.vip.extend.entity.zhao.user.ZhaoUserVO;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;

import java.util.List;

@Mapper
public interface ZhaoUserMapper extends BaseMapper<ZhaoUser> {
     

    //详情
    ZhaoUserVO selectPrimaryInfo(Integer userId);
    //列表
    List<ZhaoUserVO> selectPrimaryList(Pagination page, ZhaoUser primary);
    //添加
    int addPrimary(ZhaoUser primary);
    //修改
    int editPrimaryById(ZhaoUserDTO primary);
    //删除
    int delPrimaryById(ZhaoUserDTO primary);
    //批量删除
    int delPrimaryByIds(@Param("ids") String ids,@Param("userId")Integer userId);
    //启用禁用
    int activePrimaryByIds(ZhaoUserDTO primary);
}

十、启动项目

运行后访问接口
就可以看到数据就出来了
