springboot整合mybatis使用三:使用PageHelper 进行分页操作,并整合swagger2。使用正规的开发模式:定义统一的数据返回格式和请求模块
文章目录
前言
- 本博客是基于 springboot整合mybatis使用一:springboot整合mybatis generator,使用逆向工程生成java代码。 和 springboot整合mybatis使用二:创建开发环境架构 的基础上进行编写开发的。
- 上两个博客主要是梳理并开发了springboot整合ORM mybatis的流程,包括
mybatis-generator逆向工程
、mybatis的开发环境和配置
。 - 本博客主要梳理
PageHelper进行分页操作
、整合Swagger2
、定义统一的数据返回格式和请求模块
三大功能。 - GitHub地址如下:https://github.com/fengfanli/springboot-mybatis,在
dev02分支上
。即可给星哦。 - 可使用
git branch -b https://github.com/fengfanli/springboot-mybatis.git
,进行拉取。

二、application.yml配置
1. 新增配置
# 分页配置
pagehelper:
# 分页插件会自动检测当前的数据库链接,自动选择合适的分页方式。你也可以配置helperDialect属性来指定分页插件使用哪种方言
helper-dialect: mysql
# 分页合理化参数,默认值为false。当该参数设置为 true 时,pageNum<=0 时会查询第一页, pageNum>pages(超
# 过总数时),会查询最后一页。默认false 时,直接根据参数进行查询
reasonable: true
# log日志
#mybatis:
# configuration:
# log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
logging:
level:
com.feng.dao: debug
#swagger
swagger2:
enable: true
2. 全配置
server:
port: 8086
spring:
application:
name: company-frame
datasource:
type: com.alibaba.druid.pool.DruidDataSource
druid:
driver-class-name: com.mysql.jdbc.Driver
url: jdbc:mysql://192.168.131.168:3306/CLASS?useUnicode=true&characterEncoding=utf-8&useSSL=false
username: root
password: Dataadt123!
mybatis:
# 配置映射类所在的包名
type-aliases-package: com.feng.bean, com.feng.vo.req, com.feng.vo.resp
# 配置 mapper xml 文件所在的路径, 如果不配置 会报错:org.apache.ibatis.binding.BindingException: Invalid bound statement (not found)
# 也就是 java 找不到 mapper 的 xml 文件中的语句
mapper-locations: classpath:mapper/*.xml
# mybatis 打印 SQL 语句
# configuration:
# log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
pagehelper:
# 分页插件会自动检测当前的数据库链接,自动选择合适的分页方式。你也可以配置helperDialect属性来指定分页插件使用哪种方言
helper-dialect: mysql
# 分页合理化参数,默认值为false。当该参数设置为 true 时,pageNum<=0 时会查询第一页, pageNum>pages(超
# 过总数时),会查询最后一页。默认false 时,直接根据参数进行查询
reasonable: true
# log日志
logging:
level:
com.feng.dao: debug
#swagger
swagger2:
enable: true
3. 打印SQL日志配置(两种)
mybatis:
configuration:
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
logging:
level:
com.feng.dao: debug
这两个配置都可以
区别在于:
第一个是启用mybatis的SQL日志打印
第二个是启用springboot的日志框架。
四、统一的数据返回格式
1. 定义统一数据返回格式(important)
统一数据返回格式包括三个数据:
-
code
:int类型,请求响应编码,0表示请求成功,其他表示失败 -
msg
:String类型,响应客户端的提示 -
data
:T 泛型,响应客户端内容
新建包 utils 存放DataResult.java
类
新建包 exception.code 存放ResponseCodeInterface.java
和BaseResponseCode.java
DataResult.java
为统一数据返回格式的类ResponseCodeInterface.java
为返回数据的code和data的接口BaseResponseCode.java
为返回数据的code和data的各种情况定义。
即 com/feng/utils/DataResult.java
com/feng/exception/code/ResponseCodeInterface.java
com/feng/exception/code/BaseResponseCode.java
2. DataResult.java
编写新包新类:utils/DataResult.java
其中内容如下:
package com.feng.utils;
import com.feng.exception.code.BaseResponseCode;
import com.feng.exception.code.ResponseCodeInterface;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
@Data
public class DataResult<T> {
/*
* 请求响应code,0表示请求成功,其他表示失败
* */
@ApiModelProperty(value = "请求响应code,0表示请求成功,其他表示失败")
private int code = 0;
/*
* 响应客户端的提示
* */
@ApiModelProperty(value = "响应异常码详细情况")
private String msg;
/*
* 响应客户端内容
* */
@ApiModelProperty(value = "响应客户端内容")
private T data;
/*
* 先编写 7个 构造函数,然后再编写静态函数,便于开发
* */
public DataResult() {
this.code = BaseResponseCode.SUCCESS.getCode();
this.msg = BaseResponseCode.SUCCESS.getMsg();
this.data = null;
}
public DataResult(T data) {
this.code = BaseResponseCode.SUCCESS.getCode();
this.msg = BaseResponseCode.SUCCESS.getMsg();
this.data = data;
}
public DataResult(int code, String msg) {
this.code = code;
this.msg = msg;
}
public DataResult(int code, T data) {
this.code = code;
this.msg = null;
this.data = data;
}
public DataResult(int code, String msg, T data) {
this.code = code;
this.msg = msg;
this.data = data;
}
public DataResult(ResponseCodeInterface responseCodeInterface) {
this.code = responseCodeInterface.getCode();
this.msg = responseCodeInterface.getMsg();
this.data = null;
}
public DataResult(ResponseCodeInterface responseCodeInterface, T data) {
this.code = responseCodeInterface.getCode();
this.msg = responseCodeInterface.getMsg();
this.data = data;
}
// 以下 为定义的方法,直接调用上面封装好的 构造方法。 6个
/**
* 操作成功 data 不为null
*/
public static <T> DataResult success(T data) {
return new <T>DataResult(data);
}
/**
* 操作成功 data为null
*/
public static <T> DataResult success() {
return new <T>DataResult();
}
/**
* 自定义 返回操作 data 可控
*/
public static <T> DataResult getResult(int code, String msg, T data) {
return new <T>DataResult(code, msg, data);
}
/**
* 自定义返回 data为null
*/
public static <T> DataResult getResult(int code, String msg) {
return new <T>DataResult(code, msg);
}
/**
* 自定义返回 入参一般是异常code枚举 data为空
*/
public static <T> DataResult getResult(BaseResponseCode responseCode) {
return new <T>DataResult(responseCode);
}
/**
* 自定义返回 入参一般是异常code枚举 data 可控
*/
public static <T> DataResult getResult(BaseResponseCode responseCode, T data) {
return new <T>DataResult(responseCode, data);
}
}
4. ResponseCodeInterface.java 接口
package com.feng.exception.code;
/**
* @ClassName: ResponseCodeInterface
* TODO:类文件简单描述
* @Author: 冯凡利
* @UpdateUser: 冯凡利
* @Version: 0.0.1
*/
public interface ResponseCodeInterface {
int getCode();
String getMsg();
}
3. BaseResponseCode.java枚举类
package com.feng.exception.code;
/**
* @ClassName: BaseResponseCode
* @Description: 响应码约定
* @Author: 冯凡利
* @UpdateUser: 冯凡利
* @Version: 0.0.1
*/
public enum BaseResponseCode implements ResponseCodeInterface {
/**
* 这个要和前段约定好
* code=0:服务器已成功处理了请求。 通常,这表示服务器提供了请求的网页。
* code=4010001:(授权异常) 请求要求身份验证。 客户端需要跳转到登录页面重新登录
* code=4010002:(凭证过期) 客户端请求 刷新凭证接口
* code=4030001:没有权限禁止访问
* code=400xxxx:系统主动抛出的业务异常
* code=5000001:系统异常
*/
SUCCESS(0, "操作成功"),
SYSTEM_ERROR(5000001, "系统异常请稍后再试"),
DATA_ERROR(4000001, "传入数据异常"),
METHOD_IDENTITY_ERROR(4000002, "数据校验异常"),
ACCOUNT_ERROR(4000003, "该账号不存在"),
ACCOUNT_LOCK(4010001, "该账号被锁定,请联系系统管理员"),
ACCOUNT_PASSWORD_ERROR(4000004, "用户名密码不匹配"),
TOKEN_ERROR(4010001, "用户未登录,请重新登录"),
TOKEN_NOT_NULL(4010001, "token 不能为空"),
SHIRO_AUTHENTICATION_ERROR(4010001, "用户认证异常"),
ACCOUNT_HAS_DELETED_ERROR(4010001, "该账号已被删除,请联系系统管理员"),
TOKEN_PAST_DUE(4010002, "token失效,请刷新token"),
NOT_PERMISSION(4030001, "没有权限访问该资源"),
OPERATION_ERROR(4000005, "操作失败"),
OPERATION_MENU_PERMISSION_CATALOG_ERROR(4000006, "操作后的菜单类型是目录,所属菜单必须为默认*菜单或者目录"),
OPERATION_MENU_PERMISSION_MENU_ERROR(4000007, "操作后的菜单类型是菜单,所属菜单必须为目录类型"),
OPERATION_MENU_PERMISSION_BTN_ERROR(4000008, "操作后的菜单类型是按钮,所属菜单必须为菜单类型"),
OPERATION_MENU_PERMISSION_URL_NOT_NULL(4000009, "菜单权限的url不能为空"),
OPERATION_MENU_PERMISSION_URL_PERMS_NULL(4000010, "菜单权限的标识符不能为空"),
OPERATION_MENU_PERMISSION_URL_METHOD_NULL(4000011, "菜单权限的请求方式不能为空"),
ACCOUNT_LOCK_TIP(4010012, "该账号被锁定,请联系系统管理员"),
OPERATION_MENU_PERMISSION_UPDATE(4010013, "操作的菜单权限存在子集关联不允许变更"),
ROLE_PERMISSION_RELATION(4010014, "该菜单权限存在子集关联,不允许删除"),
NOT_PERMISSION_DELETED_DEPT(4010015, "该组织机构下还关联着用户,不允许删除"),
OLD_PASSWORD_ERROR(4010016, "旧密码不匹配"),
OPERATION_MENU_PERMISSION_URL_CODE_NULL(4000011, "菜单权限的按钮标识不能为空"),
;
/**
* 响应码
*/
private int code;
/**
* 提示
*/
private String msg;
BaseResponseCode(int code, String msg) {
this.code = code;
this.msg = msg;
}
@Override
public int getCode() {
return code;
}
@Override
public String getMsg() {
return msg;
}
}
五、请求模块
编写vo
包,此包下,新建 req
和resp
包,即:com/feng/vo/req
和 com/feng/vo/resp
req包,存放请求的数据。
resp包,存放响应的数据。
1. vo/req/StudentPageReqVo.java
@Data
@NoArgsConstructor
@AllArgsConstructor
public class StudentPageReqVo implements Serializable {
@ApiModelProperty(value = "当前第几页")
private Integer pageNum = 1;
@ApiModelProperty(value = "当前页数量")
private Integer pageSize = 10;
}
2. vo/resp/PageRespVo.java
/**
* @ClassName: PageVO
* @Description: 分页 POJO 返回的响应数据
* @createTime: 2020/2/5 15:45
* @Author: 冯凡利
* @UpdateUser: 冯凡利
* @Version: 0.0.1
*/
@Data
@NoArgsConstructor
@AllArgsConstructor
public class PageRespVo<T> implements Serializable {
/**
* 总 记录数
*/
@ApiModelProperty(value = "总记录数")
private Long totalRows;
/**
* 总 页数
*/
@ApiModelProperty(value = "总页数")
private Integer totalPages;
/**
* 当前 第几页
*/
@ApiModelProperty(value = "当前第几页")
private Integer nowPageNum;
/**
* 每页 记录数
*/
@ApiModelProperty(value = "每页记录数")
private Integer pageSize;
/**
* 当前页 记录数
*/
@ApiModelProperty(value = "当前页记录数")
private Integer curPageSize;
/**
* 数据 列表
*/
@ApiModelProperty(value = "数据列表")
private List<T> dataList;
}
六、utils工具模块
1. 定义
utils包存放各种工具类,比如分页工具类,统一数据返回格式类等等。
在utils包中编写分页工具类PageUtil.java
会在业务层用到。
1. 分页工具类:PageUtil.java(important)
package com.feng.utils;
import com.feng.vo.resp.PageRespVo;
import com.github.pagehelper.Page;
import java.util.List;
public class PageUtil {
public PageUtil() {
}
public static <T> PageRespVo<T> getPageVO(List<T> list){
PageRespVo<T> respVo = new PageRespVo<>();
if (list instanceof Page) {
Page page = (Page) list; // 将结果集 list 强转为 page 对象,则
respVo.setTotalRows(page.getTotal()); // 总记录数
respVo.setTotalPages(page.getPages());
respVo.setNowPageNum(page.getPageNum());// 当前页数
respVo.setCurPageSize(page.getPageSize());// 当前页 记录数
respVo.setPageSize(page.size()); // 每页 记录数
respVo.setDataList(page.getResult()); // 数据 列表
}
return respVo;
}
}
七、业务代码
1. bean模型层
Student.java
package com.feng.bean;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import java.io.Serializable;
@Data
@NoArgsConstructor
@AllArgsConstructor
public class Student implements Serializable {
private Integer stuId;
private String name;
private String gender;
private Integer age;
private String nation;
private static final long serialVersionUID = 1L;
@Override
public String toString() {
StringBuilder sb = new StringBuilder();
sb.append(getClass().getSimpleName());
sb.append(" [");
sb.append("Hash = ").append(hashCode());
sb.append(", stuId=").append(stuId);
sb.append(", name=").append(name);
sb.append(", gender=").append(gender);
sb.append(", age=").append(age);
sb.append(", nation=").append(nation);
sb.append(", serialVersionUID=").append(serialVersionUID);
sb.append("]");
return sb.toString();
}
}
2. controller控制层
package com.feng.controller;
import com.feng.bean.Student;
import com.feng.service.StudentService;
import com.feng.utils.DataResult;
import com.feng.vo.req.StudentPageReqVo;
import com.feng.vo.resp.PageRespVo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import java.util.List;
@RestController
public class StudentController {
@Autowired
private StudentService studentService;
@RequestMapping("/stu/{userId}")
public DataResult<Student> getStuByIdPath(@PathVariable Integer userId){
Student student = studentService.getStuById(userId);
DataResult result = DataResult.success(student);
return result;
}
@GetMapping(value = "/stu")
@ResponseBody
public DataResult<Student> getCompanyByIdGET(@RequestParam(value = "userId") Integer id) {
Student student = studentService.getStuById(id);
DataResult result = DataResult.success(student);
return result;
}
@PostMapping(value = "/stuPageInfo")
@ResponseBody
public DataResult<PageRespVo<Student>> getStuPageInfo(@RequestBody StudentPageReqVo studentPageReqVo){
PageRespVo<Student> stuPageInfo = studentService.getStuPageInfo(studentPageReqVo);
DataResult result = DataResult.success(stuPageInfo);
return result;
}
@GetMapping(value = "/allStu")
@ResponseBody
public DataResult<List<Student>> getAllStu(){
List<Student> students = studentService.getAllStu();
DataResult result = DataResult.success(students);
return result;
}
}
3. service业务层
a. StudentService 接口
package com.feng.service;
import com.feng.bean.Student;
import com.feng.vo.req.StudentPageReqVo;
import com.feng.vo.resp.PageRespVo;
import java.util.List;
public interface StudentService {
Student getStuById(Integer userId);
PageRespVo<Student> getStuPageInfo(StudentPageReqVo studentPageReqVo);
List<Student> getAllStu();
}
b. StudentServiceImpl 实现类(分页二行语句)
impl包下的StudentServiceImpl.java 实现类
package com.feng.service.impl;
import com.feng.bean.Student;
import com.feng.dao.StudentMapper;
import com.feng.service.StudentService;
import com.feng.utils.PageUtil;
import com.feng.vo.req.StudentPageReqVo;
import com.feng.vo.resp.PageRespVo;
import com.github.pagehelper.PageHelper;
import org.springframework.stereotype.Service;
import javax.annotation.Resource;
import java.util.List;
@Service
public class StudentServiceImpl implements StudentService {
@Resource
private StudentMapper studentMapper;
@Override
public Student getStuById(Integer userId) {
return studentMapper.selectByPrimaryKey(userId);
}
@Override
public PageRespVo<Student> getStuPageInfo(StudentPageReqVo studentPageReqVo) {
PageHelper.startPage(studentPageReqVo.getPageNum(), studentPageReqVo.getPageSize());
List<Student> students = studentMapper.getAllStudent();
return PageUtil.getPageVO(students);
}
@Override
public List<Student> getAllStu() {
return studentMapper.getAllStudent();
}
}
4. dao数据层
目前只有getAllStudent()
是我写的其余都是mybatis-generator自动生成的。
package com.feng.dao;
import com.feng.bean.Student;
import com.feng.vo.req.StudentPageReqVo;
import org.apache.ibatis.annotations.Param;
import java.util.List;
public interface StudentMapper {
int deleteByPrimaryKey(Integer stuId);
int insert(Student record);
int insertSelective(Student record);
Student selectByPrimaryKey(Integer stuId);
int updateByPrimaryKeySelective(Student record);
int updateByPrimaryKey(Student record);
List<Student> getAllStudent();
}
5. mapper SQL语句
其余的我就不在复制了,都是mybatis-generator逆向生成的,都在GitHub中可以查看
<select id="getAllStudent" resultType="com.feng.bean.Student">
SELECT stu_id AS stuId, name, gender, age, nation
FROM STUDENT
</select>
八、整合Swagger配置
1. Swagger2config.java
编写包 config,新建类 Swagger2config.java
package com.feng.config;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.ParameterBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.schema.ModelRef;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Parameter;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import java.util.ArrayList;
import java.util.List;
@Configuration
public class Swagger2Config {
/**
* 引入 yml 配置文件中的自定义属性
* 用来控制 swagger2 接口文档的开关,因为在生产环境中,是要关闭掉 swagger2 接口文档的
*/
@Value("${swagger2.enable}")
private boolean enable;
@Bean
public Docket createRestApi() {
/*
* 这是为了我们在用 swagger 测试接口的时候添加头部信息
* 模拟使用 header 参数,非必填
* */
List<Parameter> pars = new ArrayList<>();
ParameterBuilder tokenPar = new ParameterBuilder();
ParameterBuilder refreshTokenPar = new ParameterBuilder();
tokenPar.name("authorization").description("swagger测试用(模拟authorization传入)非必填 header").modelRef(new ModelRef("string")).parameterType("header").required(false);
refreshTokenPar.name("refresh_token").description("swagger测试用(模拟刷新token传入)非必填 header").modelRef(new ModelRef("string")).parameterType("header").required(false);
/**
* 多个的时候 就直接添加到 pars 就可以了
*/
pars.add(tokenPar.build());
pars.add(refreshTokenPar.build());
return new Docket(DocumentationType.SWAGGER_2)
// 自定义的 描述表头信息
.apiInfo(apiInfo())
// 函数返回一个ApiSerlectorBuilder 实例来控制哪些接口暴露给 Swagger ui 来展示
.select()
// 指定需要扫描的包路径
.apis(RequestHandlerSelectors.basePackage("com.feng.controller"))
.paths(PathSelectors.any())
.build()
// 添加请求头等信息
.globalOperationParameters(pars)
// 设置swagger文档的开关
.enable(enable);
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("springboot-mybatis")
.description("springboot 整合 mybatis 实战系列")
.termsOfServiceUrl("")
.version("1.0")
.build();
}
}
2. 启动类开启
开启Swagger配置,需要在主类上启动,使用 @EnableSwagger2
注解即可。
//@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
@MapperScan(value = {"com.feng.dao"})
@SpringBootApplication
@EnableSwagger2
public class SpringbootMybatisApplication {
public static void main(String[] args) {
SpringApplication.run(SpringbootMybatisApplication.class, args);
}
}
九、postman调用
1. 请求/allStu
GET http://localhost:8086/allStu
2. 分页请求/stuPageInfo
POST http://localhost:8086/stuPageInfo
请求头:Content-Type
: application/json
请求体raw中的JSON:
{
"pageNum":2,
"pageSize":2
}
3. swagger2 UI展示
http://localhost:8086/swagger-ui.html#/
