spring boot+mybatis+swagger整合增删查改代码
1.目录结构
2.配置文件（application.properties）
spring.datasource.name=shixi
spring.datasource.url=jdbc:mysql://你的地址/数据库名
spring.datasource.username=root
spring.datasource.password=密码
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
#mybatis.mapper-locations=classpath:mapper/PeopleMapper.xml,classpath:mapper/AdminMapper.xml,classpath:mapper/EmployMapper.xml
mybatis.mapper-locations=classpath:mapper/*.xml
mybatis.type-aliases-package=com.example.demo.entity
#spring.profiles.active=dev3.entity层
package com.example.demo.entity;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
@ApiModel("父类people实体类")
public class People {
@ApiModelProperty("people的id")
public Integer id; //people表的主键,也是两个子表关联的外键
@ApiModelProperty("people的姓名")
public String name; //姓名
@ApiModelProperty("people的年龄")
public Integer age; //年龄
@ApiModelProperty("people的性别")
public String sex; //性别
@ApiModelProperty("people的电话号码")
public String tel; //电话号码
@ApiModelProperty("people的工资")
public Integer wage; //工资
@ApiModelProperty("people的登录账号")
public String username; //登录账号
@ApiModelProperty("people的登录密码")
public String password; //登录密码
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 Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public String getTel() {
return tel;
}
public void setTel(String tel) {
this.tel = tel;
}
public Integer getWage() {
return wage;
}
public void setWage(Integer wage) {
this.wage = wage;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
4.mapper层的接口
package com.example.demo.mapper;
import com.example.demo.entity.People;
import org.springframework.stereotype.Repository;
import java.util.List;
@Repository
public interface PeopleMapper {
//插入
void save(People people);
//删除
int delete(int id);
//根据id查找单个
People findById(int id);
//展示全部人员
List findAll();
//根据id修改该id值的人的信息
int update(People people);
//登录验证
People login(String username,String password);
}
5.对应的mapper.xml文件的sql语句
INSERT INTO people (id,name,age,sex,tel,wage,username,password) values (null,#{name},#{age},#{sex},#{tel},#{wage},#{username},#{password})
DELETE FROM people WHERE id=#{id}
UPDATE people SET name =#{name},age=#{age},sex=#{sex},tel=#{tel},wage=#{wage}, username=#{username},password=#{password} WHERE id=#{id}
6.service层接口定义方法
package com.example.demo.service;
import com.example.demo.entity.People;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public interface PeopleService {
void save(People people);
int delete(int id);
People findById(int id);
List findAll();
int update(People people);
People login(String username,String password);
}
7.serviceImpl层接口实现类（这里并不能直接调用service层的方法，不然会报错栈溢出）
package com.example.demo.serviceImpl;
import com.example.demo.entity.People;
import com.example.demo.mapper.PeopleMapper;
import com.example.demo.service.PeopleService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import java.util.List;
@Service
@Transactional
public class PeopleServiceImpl implements PeopleService {
@Autowired
private PeopleMapper peopleMapper;
@Override
public void save(People people) {
peopleMapper.save(people);
}
@Override
public int delete(int id) {
return peopleMapper.delete(id);
}
@Override
public People findById(int id) {
return peopleMapper.findById(id);
}
@Override
public List findAll() {
return peopleMapper.findAll();
}
@Override
public int update(People people) {
return peopleMapper.update(people);
}
@Override
public People login(String username,String password){
return peopleMapper.login(username, password);
}
}
8.controller层
package com.example.demo.controller;
import com.example.demo.entity.People;
import com.example.demo.serviceImpl.PeopleServiceImpl;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.apache.shiro.authz.annotation.RequiresPermissions;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import java.util.List;
@Api(tags = "people控制类")
@RestController
@RequestMapping("people")
public class PeopleController {
@Autowired
private PeopleServiceImpl peopleServiceImpl;
//增加用户
@ApiOperation("增加一个people对象，用post方法")
@RequestMapping("add")
public void save(@RequestBody People people) {
peopleServiceImpl.save(people);
}
//删除用户
@ApiOperation("删除一个people对象，用get方法")
@RequestMapping("delete/{id}")
public int delete(@PathVariable int id) {
return peopleServiceImpl.delete(id);
}
//根据id查找单个用户
@ApiOperation("根据id查找单个people对象，用get方法")
@RequestMapping("get/{id}")
public People findById(@PathVariable int id) {
return peopleServiceImpl.findById(id);
}
//展示所有用户的列表
@ApiOperation("展示出所有people对象，用get方法")
@RequestMapping("list")
public List findAll() {
return peopleServiceImpl.findAll();
}
//修改用户信息 修改的信息中，id是？，修改的就是id为？的人员的信息
@ApiOperation("修改id对应的一个people对象，用post方法")
@RequestMapping("update")
public int update(@RequestBody People people) {
return peopleServiceImpl.update(people);
}
//登录验证
@ApiOperation("根据账号密码判断登录，用post方法")
@RequestMapping("login/{username}/{password}")
public Object login(@PathVariable String username, @PathVariable String password){
People people= peopleServiceImpl.login(username, password);
if(people!=null){
return people;
}else {
return "账号或密码错误,请重新输入！！！";
}
}
}
9.config层的SwaggerConfig插件
package com.example.demo.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;
import org.springframework.core.env.Profiles;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.service.VendorExtension;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
import java.util.ArrayList;
//url：http://localhost:8080/swagger-ui.html
@Configuration
@EnableSwagger2
public class SwaggerConfig {
//配置Swagger信息
private ApiInfo apiInfo(){
return new ApiInfo(
"ZTY",
"张天钰的Swagger API文档",
"1.0",
"https://blog.csdn.net/haiOKba?spm=1001.2014.3001.5343/",
new Contact("ZTY","https://blog.csdn.net/haiOKba?spm=1001.2014.3001.5343/","[email protected]"),

"http://www.apache.org/licenses/LICENSE-2.0",
new ArrayList());
}
//配置Swagger的Docket的bean实例
@Bean
public Docket docket(Environment environment){
Profiles profiles=Profiles.of("dev","test");
boolean flag=environment.acceptsProfiles(profiles);
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.groupName("zty")
.enable(true)
.select()
.apis(RequestHandlerSelectors.basePackage("com.example.demo.controller"))
.paths(PathSelectors.any())
.build();
}
// @Bean
// public Docket docket1(){
// return new Docket(DocumentationType.SWAGGER_2).groupName("cf");
// }
//
// @Bean
// public Docket docket2(){
// return new Docket(DocumentationType.SWAGGER_2).groupName("lh");
// }
}
