spring boot +shiro+mybaits 多數據源項目搭建【一】項目創建，mybatis plus配置

一、項目創建

打開開發工具idea,按下圖截圖方式創建項目。

直接下一步

修改相關信息

 這裏可以直接下一步不用選，後面直接修改pom.xml 文件即可。

 項目創建完成，修改pom.xml

</project>

 

二、項目配置

編輯配置文件application.yml

spring:
  profiles:
    active: dev  #對應loc表示本地，dev表示生產或者測試表的配置

新增application-dev.yml

# 項目相關配置
xiaobao:
  # 名稱
  name: spring boot
  # 版本
  version: 1.0.0
  # 版權年份
  copyrightYear: 2020

server:       #配置服務
  port: 8081         #配置服務端口

spring:
  devtools:
    restart:
      enabled: true   #熱部署啓用
  datasource:
    dynamic:
      primary: master
      datasource:
        master:
          username: root
          password: 1234
          driver-class-name: com.mysql.cj.jdbc.Driver
          url: jdbc:mysql://127.0.0.1:3306/githubspringboot?characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=GMT%2B8&nullCatalogMeansCurrent=true
        slave_1:
          username: root
          password: 1234
          driver-class-name: com.mysql.cj.jdbc.Driver
          url: jdbc:mysql://127.0.0.1:3306/xiaobaoplus?characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=GMT%2B8&nullCatalogMeansCurrent=true

新增application-loc.yml，配置同上，也可以不要。

三、代碼生成配置

創建文件

Mybatis-Plus.properties

#此處爲本項目src所在路徑（代碼生成器輸出路徑）
OutputDir=D:\\mygithub\\springboot\\generator\\src\\main\\java
#mapper.xml的生成位置
OutputDirXml=D:\\mygithub\\springboot\\generator\\src\\main\\resources
#數據庫表名(此處切不可爲空，如果爲空，則默認讀取數據庫的所有表名)
#=sys_role
tableName=
 #裝代碼的文件夾名
## F:\\xuan\\xiaobaoplus\\src\\main\\java\\cn\\mvapi\\xiaobaoplus\\xiaobaoplus\\test
className=




#設置作者
author=xiaobao
#自定義包路徑
#F:\\xuan\\xiaobaoplus\\src\\main\\java\\cn\\mvapi\\xiaobaoplus\\xiaobaoplus\\test
parent=cn.mvapi.xiaobao.common.system
#數據庫地址
url=jdbc:mysql://localhost:3306/githubspringboot?characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=GMT%2B8&nullCatalogMeansCurrent=true&tinyInt1isBit=false
userName=root
password=1234

創建生成代碼的類 CodeGenerate.java

package cn.mvapi.xiaobao.generator;

import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.core.toolkit.StringPool;
import com.baomidou.mybatisplus.generator.AutoGenerator;
import com.baomidou.mybatisplus.generator.InjectionConfig;
import com.baomidou.mybatisplus.generator.config.*;
import com.baomidou.mybatisplus.generator.config.po.TableInfo;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;
import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;

import java.util.ArrayList;
import java.util.List;
import java.util.ResourceBundle;

/**
 * @author a1838
 */
public class CodeGenerate {
    public static void main(String[] args) {

        //用來獲取Mybatis-Plus.properties文件的配置信息
        final ResourceBundle rb = ResourceBundle.getBundle("mybatis-plus");

        // 代碼生成器
        AutoGenerator mpg = new AutoGenerator();

        // 全局配置
        GlobalConfig gc = new GlobalConfig();
        gc.setOutputDir(rb.getString("OutputDir"));
        gc.setOpen(false);
        gc.setBaseResultMap(true);
        gc.setBaseColumnList(true);
        gc.setAuthor(rb.getString("author"));
        gc.setMapperName("%sDao");
        gc.setXmlName("%sMapper");
        gc.setServiceName("%sService");
        gc.setServiceImplName("%sServiceImpl");
        gc.setControllerName("%sController");

        mpg.setGlobalConfig(gc);

        // 數據源配置
        DataSourceConfig dsc = new DataSourceConfig();
        dsc.setDbType(DbType.MYSQL);
        dsc.setUrl(rb.getString("url"));
        dsc.setDriverName("com.mysql.cj.jdbc.Driver");
        dsc.setUsername(rb.getString("userName"));
        dsc.setPassword(rb.getString("password"));
        mpg.setDataSource(dsc);


        // 自定義配置
        InjectionConfig cfg = new InjectionConfig() {
            @Override
            public void initMap() {
                // to do nothing
            }
        };
        List<FileOutConfig> focList = new ArrayList<>();
        focList.add(new FileOutConfig("/templates/mapper.xml.ftl") {
            @Override
            public String outputFile(TableInfo tableInfo) {
                // 自定義輸入文件名稱
                return rb.getString("OutputDirXml") + "/mapper/" + rb.getString("className") + "/" + tableInfo.getEntityName() + StringPool.DOT_XML;
            }
        });
        cfg.setFileOutConfigList(focList);
        mpg.setCfg(cfg);
        mpg.setTemplate(new TemplateConfig().setXml(null));

        // 策略配置
        StrategyConfig strategy = new StrategyConfig();
        strategy.setNaming(NamingStrategy.underline_to_camel);
        strategy.setColumnNaming(NamingStrategy.underline_to_camel);
        strategy.setEntityLombokModel(true);
       // strategy.setInclude(new String[]{rb.getString("tableName")});

        // 包配置
        PackageConfig pc = new PackageConfig();
// pc.setModuleName("test");
        pc.setParent(rb.getString("parent"));// 自定義包路徑
/*        pc.setController("controller."+rb.getString("className"));// 這裏是控制器包名，默認 web
        pc.setEntity("model."+rb.getString("className"));
        pc.setMapper("dao."+rb.getString("className"));
        pc.setXml("mapping."+rb.getString("className"));
        pc.setService("service."+rb.getString("className"));
        pc.setServiceImpl("service."+rb.getString("className")+".impl");*/
        mpg.setPackageInfo(pc);

        mpg.setStrategy(strategy);
        mpg.setTemplateEngine(new FreemarkerTemplateEngine());
        mpg.execute();

    }
}

四、啓動上面的類，將生成的代碼拷貝到項目裏面。

在項目啓動類上添加註解，包名填寫自己的

@MapperScan(basePackages = {"cn.mvapi.xiaobao.*"})

package cn.mvapi.xiaobao;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@MapperScan(basePackages = {"cn.mvapi.xiaobao.*"})
@SpringBootApplication
public class XiaobaoApplication {

    public static void main(String[] args) {
        SpringApplication.run(XiaobaoApplication.class, args);
        System.out.println("啓動成功！");
    }

}

添加一個測試的controller

package cn.mvapi.xiaobao.projecttest;

import cn.mvapi.xiaobao.common.system.entity.SysMenu;
import cn.mvapi.xiaobao.common.system.service.SysMenuService;
import cn.mvapi.xiaobao.common.system.service.impl.SysMenuServiceImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import java.util.List;

@Controller
public class testController {
    @Autowired
    private SysMenuServiceImpl sysMenuService;
    @ResponseBody
    @RequestMapping("dbtest")
    public List<SysMenu> dbtest(){
        return sysMenuService.list();
    }
}

 訪問測試地址，能訪問到數據代表成功。
