影视后台管理day1

一、前言

两周的实训后，对所学的进行复盘（也是混博客）

​ 后端技术栈使用springboot 、mybatisplus，前端技术栈 使用 vue.js、elmentui、vue-admin-template，进行整体架构的搭建实现前后端分离。spring Security 、redis 、knife4j（swagger2）、阿里云OSS、阿里云视频点播(VOD)、Spring等技术。

二、搭建工程

搭建聚合工程 movie-parent是父工程，

common、model、service-system-v是子工程

common-util、service-util是common的子工程

具体的功能，将在后面实现

三、导入依赖

要使用到Maven，自行配置本地仓库

如果需要手动添加，下面是Maven repository（会抽风，试着切换不同网络）

https://mvnrepository.com/

3.1 movie-paremt的pom.xml

添加修改如下

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

四、新建数据库

新建数据库movie-auth

CREATE TABLE `sys_role` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT '角色id',
  `role_name` varchar(20) NOT NULL DEFAULT '' COMMENT '角色名称',
  `role_code` varchar(20) DEFAULT NULL COMMENT '角色编码',
  `description` varchar(255) DEFAULT NULL COMMENT '描述',
  `create_time` datetime DEFAULT NULL COMMENT '创建时间',
  `update_time` datetime DEFAULT NULL COMMENT '修改时间',
  `is_deleted` tinyint(3) NOT NULL DEFAULT '0' COMMENT '删除标记（0:可用 1:已删除）',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=14 DEFAULT CHARSET=utf8 COMMENT='角色';

数据库脚本 （蓝奏云不能分享sql，请先修改后缀名在运行

https://kirei7.lanzouy.com/itCbb11jj9id
密码:c74q

五、实体类和vo对象

在model工程创建如下包

BaseEntity

@Data
public class BaseEntity implements Serializable {

   @TableId(type = IdType.AUTO)
   private Long id;
   //private String id;

    @TableField(value = "create_time",fill = FieldFill.INSERT)
    private Date createTime;

    @TableField(value = "update_time",fill = FieldFill.INSERT_UPDATE)
    private Date updateTime;

    @TableLogic  //逻辑删除 默认效果 0 没有删除 1 已经删除
    @TableField("is_deleted")
    private Integer isDeleted;

    @TableField(exist = false)
    private Map<String,Object> param = new HashMap<>();
}

SysRole

@Data
@TableName("sys_role")
public class SysRole extends BaseEntity {
   
   private static final long serialVersionUID = 1L;

   @TableField("role_name")
   private String roleName;

   @TableField("role_code")
   private String roleCode;

   @TableField("description")
   private String description;

}

SysRoleQueryVo

public class SysRoleQueryVo implements Serializable {


   private static final long serialVersionUID = 1L;
   
   private String roleName;

   public String getRoleName() {
      return roleName;
   }

   public void setRoleName(String roleName) {
      this.roleName = roleName;
   }
}

六、工具类和配置类

• 导入 mybatisplus 分页插件配置类
• 导入自动填充的插件配置类

以上是放在 service-util

自动填充配置类

// 做自动填充  工具类
@Component
public class MybatisplusObjectMetaHandler implements MetaObjectHandler {


    // mp 在执行添加的时候，这个方法会被执行
    @Override
    public void insertFill(MetaObject metaObject) {

        this.setFieldValByName("createTime",new Date(),metaObject);

    }

    // mp 在执行修改的时候，这个方法会执行
    @Override
    public void updateFill(MetaObject metaObject) {
        this.setFieldValByName("updateTime",new Date(),metaObject);

    }
}

分页插件配置类

package org.kirei.system.config;

import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.transaction.annotation.EnableTransactionManagement;

/**
 * MybatisPlus配置类
 *
 */

// 这里主要是配置分页插件
@EnableTransactionManagement
@Configuration
@MapperScan("org.kirei.system.mapper")
public class MybatisPlusConfig {

    /**
     *
     * @return
     */
    @Bean
    public MybatisPlusInterceptor addPaginationInnerInterceptor(){
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        //向Mybatis过滤器链中添加分页拦截器
        PaginationInnerInterceptor innerInterceptor = new PaginationInnerInterceptor(DbType.MYSQL);
        interceptor.addInnerInterceptor(innerInterceptor);
        return interceptor;
    }

}

七、配置文件

application-dev.yml、application.yml

在 service-system-v工程下resources里

application-dev.yml

server:
  port: 8088
mybatis-plus:
  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl # 查看日志
    type-aliases-package: org.kirei.model.system #配置实体类的别名
spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/movie-auth?characterEncoding=utf-8&useSSL=false
    username: root
    password: 123456

application.yml

spring:
  application:
    name: service-system-v
  profiles:
    active: dev

八、角色模块开发

九、编写mapper接口

package com.kirei.system.mapper;

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.kirei.model.system.SysRole;

public interface SysRoleMapper extends BaseMapper<SysRole> {

}

十、编写接口和实现类

接口

public interface SysRoleService extends IService<SysRole>{
    
}

实现类

@Service
public class SysRoleServiceImpl extends ServiceImpl<SysRoleMapper, SysRole> implements SysRoleService {
    
}

十一、编写controller

@Api(tags = "角色管理控制器")
@RestController
@RequestMapping("/admin/system/sysRole")
public class SysRoleController {

    @Autowired
    private SysRoleService sysRoleService;

    // http://localhost:8088/admin/system/sysRole/findAll

    // http://localhost:8088/admin/system/sysRole/findAll

    // 查询全部记录
    @ApiOperation("查询全部接口")
    @GetMapping("/findAll")
    public List<SysRole> findAll()
    {
        List<SysRole> list = this.sysRoleService.list();
        return list;
    }

    // 根据id 去逻辑删除
    @ApiOperation("逻辑删除接口")
    @DeleteMapping("/remove/{id}")
    public boolean removeRole(@PathVariable Long id)
    {
        boolean isDel = this.sysRoleService.removeById(id);
        return isDel;
    }
}

十二、使用Swagger2

service-util下

添加依赖

<dependency>
    <groupId>com.github.xiaoymin</groupId>
    <artifactId>knife4j-spring-boot-starter</artifactId>
</dependency>

添加配置类

/**
 * knife4j配置信息
 */
@Configuration
@EnableSwagger2WebMvc
public class Knife4jConfig {

    @Bean
    public Docket adminApiConfig(){
        List<Parameter> pars = new ArrayList<>();
        ParameterBuilder tokenPar = new ParameterBuilder();
        tokenPar.name("token")
                .description("用户token")
                .defaultValue("")
                .modelRef(new ModelRef("string"))
                .parameterType("header")
                .required(false)
                .build();
        pars.add(tokenPar.build());
        //添加head参数end

        Docket adminApi = new Docket(DocumentationType.SWAGGER_2)
                .groupName("adminApi")
                .apiInfo(adminApiInfo())
                .select()
                //只显示admin路径下的页面
                .apis(RequestHandlerSelectors.basePackage("com.kirei"))
                .paths(PathSelectors.regex("/admin/.*"))
                .build()
                .globalOperationParameters(pars);
        return adminApi;
    }

    private ApiInfo adminApiInfo(){

        return new ApiInfoBuilder()
                .title("后台管理系统-API文档")
                .description("本文档描述了管理系统微服务接口定义")
                .version("1.0")
                .contact(new Contact("kirei", "http://qq.com", "kirei@qq.com"))
                .build();
    }


}

十三、测试

十四、统一返回结果

14.1 导入工具类

• 导入统一结果集 Reuslt 对象

• 导入统一的结果状态码对象 ResultCodeEnum

  以上是放在 common-util

  

  package org.kirei.system.util;
  
  
  import lombok.Data;
  
  /**
   * 全局统一返回结果类
   *
   */
  @Data
  public class Result<T> {
  
      //返回码
      private Integer code;
  
      //返回消息
      private String message;
  
      //返回数据
      private T data;
  
      public Result(){}
  
      // 返回数据
      protected static <T> Result<T> build(T data) {
          Result<T> result = new Result<T>();
          if (data != null)
              result.setData(data);
          return result;
      }
  
      public static <T> Result<T> build(T body, Integer code, String message) {
          Result<T> result = build(body);
          result.setCode(code);
          result.setMessage(message);
          return result;
      }
  
      public static <T> Result<T> build(T body, ResultCodeEnum resultCodeEnum) {
          Result<T> result = build(body);
          result.setCode(resultCodeEnum.getCode());
          result.setMessage(resultCodeEnum.getMessage());
          return result;
      }
  
      public static<T> Result<T> ok(){
          return Result.ok(null);
      }
  
      /**
       * 操作成功
       * @param data  baseCategory1List
       * @param <T>
       * @return
       */
      public static<T> Result<T> ok(T data){
          Result<T> result = build(data);
          return build(data, ResultCodeEnum.SUCCESS);
      }
  
      public static<T> Result<T> fail(){
          return Result.fail(null);
      }
  
      /**
       * 操作失败
       * @param data
       * @param <T>
       * @return
       */
      public static<T> Result<T> fail(T data){
          Result<T> result = build(data);
          return build(data, ResultCodeEnum.FAIL);
      }
  
      public Result<T> message(String msg){
          this.setMessage(msg);
          return this;
      }
  
      public Result<T> code(Integer code){
          this.setCode(code);
          return this;
      }
  }
  

package org.kirei.system.util;

import lombok.Getter;

/**
 * 统一返回结果状态信息类
 *
 */
@Getter
public enum ResultCodeEnum {

    SUCCESS(200,"成功"),
    FAIL(201, "失败"),
    SERVICE_ERROR(2012, "服务异常"),
    DATA_ERROR(204, "数据异常"),
    ILLEGAL_REQUEST(205, "非法请求"),
    REPEAT_SUBMIT(206, "重复提交"),
    ARGUMENT_VALID_ERROR(210, "参数校验异常"),

    LOGIN_AUTH(208, "未登陆"),
    PERMISSION(209, "没有权限"),
    ACCOUNT_ERROR(214, "账号不正确"),
    PASSWORD_ERROR(215, "密码不正确"),
    LOGIN_MOBLE_ERROR( 216, "账号不正确"),
    ACCOUNT_STOP( 217, "账号已停用"),
    NODE_ERROR( 218, "该节点下有子节点，不可以删除")
    ;

    private Integer code;

    private String message;

    private ResultCodeEnum(Integer code, String message) {
        this.code = code;
        this.message = message;
    }
}

14.2 修改controller

@ApiOperation("查询全部接口")
@GetMapping("/findAll")
public Result findAll()
{

    List<SysRole> list = this.sysRoleService.list();
   return Result.ok(list);
}

// 根据id 去逻辑删除
@ApiOperation("逻辑删除接口")
@DeleteMapping("/remove/{id}")
public Result removeRole(@PathVariable Long id)
{
    boolean isSuccess = this.sysRoleService.removeById(id);
    if (isSuccess)
    {
        return Result.ok();
    }
    else
    {
        return Result.fail();
    }
}

十五、统一异常处理

15.1 全局和特定异常

package org.kirei.system.exception;

import org.kirei.system.util.Result;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;

@ControllerAdvice
public class GlobalException {

    //1.全局异常
    @ExceptionHandler(Exception.class)
    @ResponseBody
    public Result error(Exception e)
    {
        System.out.println("全局执行....");;
        e.printStackTrace();
        return Result.fail().message("执行了全局异常处理...");
    }
    //2.特定异常处理
    @ExceptionHandler(ArithmeticException.class)
    @ResponseBody
    public Result error(ArithmeticException e)
    {
        System.out.println("特定执行.");
        e.printStackTrace();
        return Result.fail().message("执行了特定异常处理..");
    }

}

15.2 自定义异常

package org.kirei.system.exception;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class MyCustomerException extends RuntimeException{
    private Integer code;
    private String msg;
}

十六、角色管理开发

16.1 分页查询

16.1.1 controller添加

// 分页 + 查询
@ApiOperation("角色分页查询")
@GetMapping("/{page}/{limit}")
public Result findRoleByPageQuery(@PathVariable Long page,
                                  @PathVariable Long limit,
                                  SysRoleQueryVo roleQueryVo)
{
    IPage<SysRole> page1 = new Page<>(page,limit);
    page1 =   this.sysRoleService.selectPage(page1,roleQueryVo);
    return Result.ok(page1);
}

16.1.2 service添加

public interface SysRoleService extends IService<SysRole>{

IPage<SysRole> selectPage(IPage<SysRole> page1, SysRoleQueryVo roleQueryVo);
}

16.1.3 实现类添加

@Service
public class SysRoleServiceImpl extends ServiceImpl<SysRoleMapper,SysRole> implements SysRoleService {

    @Override
    public IPage<SysRole> selectPage(IPage<SysRole> page1, SysRoleQueryVo roleQueryVo) {
        IPage<SysRole> iPage =   this.baseMapper.selectPage(page1,roleQueryVo);
        return iPage;
    }
}

16.4 mapper编写

@Repository
public interface SysRoleMapper extends BaseMapper<SysRole> {
    public IPage<SysRole> selectPage(IPage<SysRole> page1, @Param("vo") SysRoleQueryVo roleQueryVo);
}

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="org.kirei.system.mapper.SysRoleMapper">

    <resultMap id="RoleMap" type="org.kirei.model.system.SysRole" autoMapping="true">
    </resultMap>

    <!-- 用于select查询公用抽取的列 -->
    <sql id="columns">
        id,role_name,role_code,description,create_time,update_time,is_deleted
    </sql>

    <select id="selectPage" resultMap="RoleMap">
        select <include refid="columns" />
        from sys_role
        <where>
            <if test="vo.roleName != null and vo.roleName != ''">
                and role_name like CONCAT('%',#{vo.roleName},'%')
            </if>
            and is_deleted = 0
        </where>
        order by id desc
    </select>

</mapper>

16.5 swagger测试一下

16.2 添加角色

16.2.1 controller

    // 添加
    @ApiOperation("添加角色")
    @PostMapping("addRole")
    public Result addRole(@RequestBody SysRole sysRole)
    {
        boolean isAdd = this.sysRoleService.save(sysRole);
        return isAdd?Result.ok():Result.fail(); //对比使用if else语句
    }

16.2.2 service

直接利用mp的service中的方法，所以不用自己写

可以自行去官方文档学习

extends IService

具体方法如下

public interface IService<T> {
    int DEFAULT_BATCH_SIZE = 1000;

default boolean save(T entity) {
    return SqlHelper.retBool(this.getBaseMapper().insert(entity));
}

16.3 修改角色

16.3.1 controller

// 根据id 去获取一个role
@GetMapping("findRoleById/{id}")
@ApiOperation("根据id查询")
public Result findRoleById(@PathVariable Long id)
{
    SysRole sysRole = this.sysRoleService.getById(id);
    return Result.ok(sysRole);
}
// 修改
@ApiOperation("修改角色")
@PostMapping("updateRole")
public Result updateRole(@RequestBody SysRole sysRole)
{
    boolean isUpdate = this.sysRoleService.updateById(sysRole);
    return isUpdate?Result.ok():Result.fail();
}

16.3.2 service

使用mp中自带的方法，可以自行去官方文档学习

16.4 删除单个角色

删除角色时，表中的字段 is_delete的值作为逻辑删除的具现

16.4.1 controller

//删除单个角色信息
@ApiOperation("根据主键id删除角色信息")
@DeleteMapping("removeById/{id}")
public Result deleteById(@PathVariable Long id){
    boolean isDel = this.sysRoleService.removeById(id);
    return isDel?Result.ok():Result.fail();
}

16.5 批量删除角色

16.5.1 controller

// 批量删除
@ApiOperation("批量删除")
@DeleteMapping("batchRemove")
public Result batchRemove(@RequestBody List<Long> ids) {
    boolean isRmove = this.sysRoleService.removeByIds(ids);
    return isRmove ? Result.ok() : Result.fail();
}

swagger测试一下上述功能，查看数据库表中字段的变化
