承接上文：Springboot快速搭建跨域API接口(idea社区版2023.1.4+apache-maven-3.9.3-bin)
MyBatis的Maven包
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <!-- 热部署 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> </dependency> <!-- Web支持 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!-- JDBC --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> </dependency> <!-- MySQL驱动 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <!-- 集成MyBatis --> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>2.1.2</version> </dependency> <!-- junit --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <scope>test</scope> </dependency> <!-- 测试 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> <exclusions> <exclusion> <groupId>org.junit.vintage</groupId> <artifactId>junit-vintage-engine</artifactId> </exclusion> </exclusions> </dependency>
引入后别忘记刷新Maven。
application.properties配置文件位置
添加以下内容：
# 配置数据库驱动 spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver # 配置数据库url spring.datasource.url=jdbc:mysql://rm-bp1zq3879r28p726lco.mysql.rds.aliyuncs.com:3306/test?characterEncoding=utf8 # 配置数据库用户名 spring.datasource.username=qwe8403000 # 配置数据库密码 spring.datasource.password=Qwe8403000 # 指定MyBatis配置文件位置 mybatis.mapper-locations=classpath:mapper/*.xml # 指定模型位置 mybatis.typeAliasesPackage=com.item.model # 修改端口号避免冲突 server.port=8088 # 服务路径 server.servlet.context-path=/MyAPI
项目结构层次
编码过程
按照上图给的顺序一次创建文件并写入给与的示例代码，数据库里面有表，可以直接放心使用。
1、model/Users.java
package com.item.model;
public class Users {
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPwd() {
return pwd;
}
public void setPwd(String pwd) {
this.pwd = pwd;
}
public String getNickName() {
return nickName;
}
public void setNickName(String nickName) {
this.nickName = nickName;
}
@Override
public String toString() {
return "Users{" +
"id=" + id +
", userName='" + userName + '\'' +
", pwd='" + pwd + '\'' +
", nickName='" + nickName + '\'' +
'}';
}
private int id;
private String userName;
private String pwd;
private String nickName;
}2、dao/UsersMapper.java
package com.item.dao;
import com.item.model.Users;
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Repository;
import java.util.List;
/**
* 数据访问组件
*/
@Repository
public interface UsersMapper {
List<Users> GetInfo();
List<Users> SelectName(@Param("nickName") String nickName);
Users UsersSelectById(@Param("id") int id);
int UsersAddInfo(
@Param("userName") String userName,
@Param("pwd") String pwd,
@Param("nickName") String nickName
);
int UsersUpdateInfo(
@Param("pwd") String pwd,
@Param("id") int id
);

select * from users
</select>
<!-- 用做传递参数测试·支持空查询，返回所有信息 -->
<select id="SelectName" resultType="Users">
select * from users where nickName like "%${nickName}%"
</select>
<!-- id精准查询 -->
<select id="UsersSelectById" resultType="Users">
select * from users where id=#{id}
</select>
<!-- 增加 -->
<insert id="UsersAddInfo">
insert into users values(0,"${userName}","${pwd}","${nickName}");
</insert>
<!-- 修改 -->
<update id="UsersUpdateInfo">
update users set pwd="${pwd}" where id=#{id}
</update>
<!-- 删除 -->
<delete id="UsersDeleteById">
delete from users where id=#{id}
</delete>
</mapper>4、service/UsersService.java
package com.item.service;
import com.item.model.Users;
import java.util.List;
public interface UsersService {
/**
* 获取所有
* @return
*/
List<Users> GetInfo();
/**
* 获取nickName的模糊查询结果集
* @param nickName
* @return
*/
List<Users> SelectName(String nickName);
/**
* id精准查询
* @param id
* @return
*/
Users UsersSelectById(int id);
/**

* @param userName
* @param pwd
* @param nickName
* @return
*/
int UsersAddInfo(
String userName,
String pwd,
String nickName
);
/**

}5、serviceimpl/UsersServiceImpl.java

for (int i = 0; i < bytes.length; i++) {
ret.append(HEX_DIGITS[(bytes[i] >> 4) & 0x0f]);
ret.append(HEX_DIGITS[bytes[i] & 0x0f]);
}
return ret.toString();
}
@Override
public int UsersDeleteById(int id) {
return usersMapper.UsersDeleteById(id);
}
}6、controller/UsersController.java
package com.item.controller;
import com.item.model.Users;
import com.item.service.UsersService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.*;
import javax.servlet.http.HttpServletRequest;
import java.util.HashMap;
import java.util.List;
@RestController
@CrossOrigin
public class UsersController {
@Autowired
private UsersService usersService;
@GetMapping("/GetInfoApi")
public Object GetInfoApi(){
List<Users> list=usersService.GetInfo();
HashMap<String,Object> map=new HashMap<String,Object>();
map.put("state",true);
map.put("msg","成功");
map.put("result",list);
return map;
}
@GetMapping("/GetName")
public Object GetName(HttpServletRequest request,Model model){
String nickName = request.getParameter("nickName");
List<Users> list=usersService.SelectName(nickName);
HashMap<String,Object> map=new HashMap<String,Object>();

HashMap<String,Object> map=new HashMap<String,Object>();
map.put("state",true);
map.put("msg","成功");
map.put("result",users);
return map;
}
/**

*/
@PostMapping(value = "/UserUpdateInfoApi")
public Object UserUpdateInfoApi(HttpServletRequest request,Model model){

}
}7、Action.java
package com.item;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
@MapperScan("com.item.dao")
@SpringBootApplication
public class Action extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Action.class);
}
public static void main(String[] args) {
//一定是被@SpringBootApplication标记的类
SpringApplication.run(Action.class, args);
}
}启动校验
查看端口号以及路由设置
端口号以及路由的路径已经设置，根据路径进行访问。
http://localhost:8088/MyAPI/GetName
访问成功。
总结
现在我们已经搭建了服务的基础环境，可以创建跨域的接口，也可以操作数据库，那么也就代表着我们可以正常的写接口项目了，不过我们写好的接口暂时没办法直接提供给前端人员，所以我们还需要配置一个swagger或者是使用Eolink插件一键上传接口来方便与前端人员交互。

下节我们来配置swagger。
