springCloud+mybatis搭建项目

一、新建项目

1：

点击next

2、

3、下一步选择插件（可不选）

web下我选择spring web

项目新建完成

此时我的项目如下图

二、相关项目配置

1：打开swagger web服务

我们需要在Application启动程序上添加@EnableSwagger2注解同时添加swagger依赖，否则打开页面会显示

a、添加依赖1

<dependency>
    <groupId>io.github.wilson-he</groupId>
    <artifactId>swagger2-spring-boot-starter</artifactId>
    <version>LATEST</version>
</dependency>

并且在yml文件中添加下面配置

swagger:
  print-init: true
  enabled: true
  security-configuration:
    client-id: client-1
    client-secret: secretA
    scope-separator: \,
    use-basic-authentication-with-access-code-grant: true
  dockets:
    docket-api:
      base-package: cn.yufeng.transport.controller
      group-name: api
      api-info:
        title: 要展示的接口名称
        description: RESTful接口描述
        version: 版本号
        license: 版权
      global-parameters:
      - name: token
        description: Access Token
        param-type: header

swagger为

b、添加依赖2

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>2.7.0</version>
</dependency>
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>2.7.0</version>
</dependency>

swagger页面

两种依赖任选一种

三、环境管理配置

1、application.yml与对应版本yml文件配置

到此可以启动开始写接口了

四、书写一个接口案例

1、项目目录设置如下

实体类：

package com.example.myproject.pojo;

import lombok.Data;

/**
 * @Title: Company
 * @author: andy
 * @date: 2020/1/8 11:35
 */
@Data
public class Company {
    private String id;
    private String mySubjectId;
    private String custSubjectName;
    private String companyContact;
    private String contactWay;
}

创建CompanyInfoMapper.java

package com.example.myproject.mapper;

import com.example.myproject.bean.DataResult;

/**
 * @Title: CompanyInfoMapper
 * @author: andy
 * @date: 2020/1/8 11:44
 */
public interface CompanyInfoMapper {
    DataResult getCompanyList();
}

创建对应的CompanyInfoMapper.xml

<?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="com.example.myproject.mapper.CompanyInfoMapper">
    <resultMap id="baseResultMap" type="com.example.myproject.pojo.Company">
        <id column="id_" property="id" jdbcType="VARCHAR"/>
        <result column="my_subject_id" property="mySubjectId" />
        <result column="company_contact" property="companyContact" jdbcType="VARCHAR" />
        <result column="contact_way" property="contactWay" jdbcType="VARCHAR" />
        <result column="cust_subject_name" property="custSubjectName" jdbcType="VARCHAR" />
    </resultMap>
    <select id="getCompanyList" resultMap="baseResultMap" >
        select id_, my_subject_id, company_contact, contact_way, cust_subject_name from set_company_info
    </select>
</mapper>

创建CompanyInfoService.java

package com.example.myproject.service;

import com.example.myproject.bean.DataResult;

/**
 * @Title: CompanyInfoService
 * @author: andy
 * @date: 2020/1/8 15:12
 */
public interface CompanyInfoService {
    DataResult getCompanyList();
}

CompanyInfoServiceImpl.java

package com.example.myproject.service.impl;

import com.example.myproject.bean.DataResult;
import com.example.myproject.mapper.CompanyInfoMapper;
import com.example.myproject.service.CompanyInfoService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
 * @Title: CompanyInfoServiceImpl
 * @author: andy
 * @date: 2020/1/8 17:21
 */
@Service
public class CompanyInfoServiceImpl implements CompanyInfoService {

    @Autowired
    private CompanyInfoMapper companyInfoMapper;

    @Override
    public DataResult getCompanyList() {
        return companyInfoMapper.getCompanyList();
    }
}

创建CompanyInfoController.java

package com.example.myproject.controller;

import com.example.myproject.bean.DataResult;
import com.example.myproject.service.CompanyInfoService;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @Title: CompanyInfoController
 * @author: andy
 * @date: 2020/1/8 18:29
 */
@RestController
@RequestMapping("/companyInfo")
public class CompanyInfoController {

    @Autowired
    private CompanyInfoService companyInfoService;

    @ApiOperation("获取企业列表")
    @PostMapping(value = "/v1/getCompanyList")
    public DataResult getCompanyList() {
        return companyInfoService.getCompanyList();
    }
}

到此一个完整的接口开发完了，启动项目swagger显示如图

要记得在yml下添加mapper.xml的扫描

mybatis-plus:
  mapper-locations: /mybatis/mapper/*Mapper.xml（mapper.xml的地址）

如果有参数填写完参数点击try it out 就能访问你的接口了

如果觉得不好，不要喷，请指出了，谢谢
