Mysql多数据源Springboot+mybatis+druid+dynamic-datasource

一、添加POM引用

二、配置连接属性

三、代码

1、Application代码

import com.alibaba.druid.spring.boot.autoconfigure.DruidDataSourceAutoConfigure;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication(exclude = DruidDataSourceAutoConfigure.class)
public class Application {
    public static void main(String[] args)
    {
        SpringApplication.run(Application.class);
    }
}

2、Mapper代码

3、controller代码

import com.lubansoft.model.Poi;
import com.lubansoft.service.Poi1Service;
import com.lubansoft.service.PoiService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.Arrays;
import java.util.List;

@RequestMapping("/poi")
@RestController
@Api("PoiController")
public class PoiController {
    @Autowired
    private PoiService poiService;
    @Autowired
    private Poi1Service poi1Service;

    @ApiOperation("insert")
    @PostMapping("/insert")
    public String insert(@RequestParam("poi") Poi poi){
        poiService.insert(Arrays.asList(poi));
        return "插入成功";
    }

    @ApiOperation("获取全部主数据库")
    @GetMapping("/getAll")
    public List<Poi> getAll(){
        return poiService.getAll();
    }

    @ApiOperation("获取全部从数据库")
    @GetMapping("/getAll1")
    public List<Poi> getAll1(){
        return poi1Service.getAll();
    }
}

4、model

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Getter;
import lombok.Setter;

@ApiModel("Poi")
@Getter
@Setter
public class Poi {
    @ApiModelProperty("id")
    private String id;
    @ApiModelProperty("poiid")
    private String poiid;
    @ApiModelProperty("title")
    private String title;
    @ApiModelProperty("address")
    private String address;
    @ApiModelProperty("lon")
    private String lon;
    @ApiModelProperty("lat")
    private String lat;
    @ApiModelProperty("city")
    private String city;
    @ApiModelProperty("category_name")
    private String category_name;
    @ApiModelProperty("checkin_num")
    private String checkin_num;
    @ApiModelProperty("photo_num")
    private String photo_num;
}

5、services

import com.baomidou.dynamic.datasource.annotation.DS;
import com.lubansoft.mapper.PoiMapper;
import com.lubansoft.model.Poi;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@DS("master")
@Service
public class PoiService {
    @Autowired
    PoiMapper poiMapper;

    public Boolean insert(List<Poi> pois){
        poiMapper.insert(pois);
        return Boolean.TRUE;
    }

    public List<Poi> getAll(){
        return poiMapper.getAll();
    }
}

import com.baomidou.dynamic.datasource.annotation.DS;
import com.lubansoft.mapper.PoiMapper;
import com.lubansoft.model.Poi;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@DS("slave")
@Service
public class Poi1Service {
    @Autowired
    PoiMapper poiMapper;

    public Boolean insert(List<Poi> pois){
        poiMapper.insert(pois);
        return Boolean.TRUE;
    }

    public List<Poi> getAll(){
        return poiMapper.getAll();
    }
}

 

6、swagger

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;

@Configuration
public class SwaggerConfig {
    Boolean swaggerEnabled=true;
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_12).apiInfo(apiInfo())
                // 是否开启
                .enable(swaggerEnabled).select()
                // 扫描的路径包
                .apis(RequestHandlerSelectors.basePackage("com.test.controller"))
                // 指定路径处理PathSelectors.any()代表所有的路径
                .paths(PathSelectors.any()).build().pathMapping("/");
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("SpringBoot-Swagger3集成和使用-demo示例")
                .description("springboot | swagger")
                // 作者信息
                .contact(new Contact("name", "个人主页url", "email"))
                .version("1.0.0")
                .build();
    }
}
