一、通用部分

1. 通用依賴

<dependency><groupId>com.github.pagehelper</groupId><artifactId>pagehelper-spring-boot-starter</artifactId><version>1.2.5</version></dependency><dependency><groupId>org.mybatis.generator</groupId><artifactId>mybatis-generator-core</artifactId><version>1.3.2</version></dependency><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>1.3.2</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>druid-spring-boot-starter</artifactId><version>1.1.10</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency>

2. 通用配置 yml

spring:datasource:username: rootpassword: rooturl: jdbc:mysql://127.0.0.1:3306/xxx?useUnicode=true&characterEncoding=UTF-8&useSSL=false&autoReconnect=true&failOverReadOnly=false&serverTimezone=CTTdriver-class-name: com.mysql.cj.jdbc.Drivertype: com.alibaba.druid.pool.DruidDataSourcedruid:# 下面為連接池的補充設置，應用到上面所有數據源中# 初始化大小，最小，最大initial-size: 5min-idle: 5max-active: 20# 配置獲取連接等待超時的時間max-wait: 60000stat-view-servlet:enabled: truelogin-username: adminlogin-password: adminallow:deny:url-pattern: /druid/*

二、 springboot3.x 集成通用mapper

2.1. pom.xml

<dependency><groupId>tk.mybatis</groupId><artifactId>mapper</artifactId><version>4.0.3</version></dependency>

2.2. yml

mybatis:mapper-locations: classpath:mapper/*/*Mapper.xmltype-aliases-package: com.coderman.api.*.pojoconfiguration:map-underscore-to-camel-case: true

2.3. mapper接口

package com.coderman.api.system.mapper;import com.coderman.api.system.pojo.User; import tk.mybatis.mapper.common.Mapper;/*** @Author gblfy* @Date 2020/3/7 15:03* @Version 1.0**/ public interface UserMapper extends Mapper<User> { }

2.4. 啟動類加@MapperScan注解

import tk.mybatis.spring.annotation.MapperScan;

@MapperScan("com.coderman.api.*.mapper")

2.5. 啟動類加@ComponentScan注解

import org.springframework.context.annotation.ComponentScan;

@ComponentScan("com.coderman.*")

注：掃描包，例如：掃描配置類上有@Configuration注解的類

三、 springboot3.x 集成通用Mybatis

3.1. pom.xml

<dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>1.3.2</version></dependency>

3.2. yml

mybatis:mapper-locations: classpath:mapper/*/*Mapper.xmltype-aliases-package: com.coderman.api.*.pojoconfiguration:map-underscore-to-camel-case: true

3.3. mapper接口

package com.coderman.api.system.mapper;import com.coderman.api.system.pojo.User; import tk.mybatis.mapper.common.Mapper;/*** @Author gblfy* @Date 2020/3/7 15:03* @Version 1.0**/ public interface UserMapper{ }

3.4. 啟動類加@MapperScan注解

import org.mybatis.spring.annotation.MapperScan;

@MapperScan("com.coderman.api.*.mapper")

3.5. 啟動類加@ComponentScan注解

import org.springframework.context.annotation.ComponentScan;

@ComponentScan("com.coderman.*")

注：掃描包，例如：掃描配置類上有@Configuration注解的類

四、 springboot3.x 集成通用MybatisPlus

4.1. pom.xml

<!--Mybatis-Plus 啟動器--><dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-boot-starter</artifactId><version>3.3.1.tmp</version></dependency>

4.2. yml

#實體掃描，多個package用逗號或者分號分隔 mybatis-plus:typeAliasesPackage: com.gblfy.springboot.mybatisplus.entitymapper-locations:- classpath*:com/gblfy/springboot/**/mapping/*.xml

4.3. mapper接口

package com.gblfy.springboot.mybatisplus.mapper;import com.baomidou.mybatisplus.core.conditions.Wrapper; import com.baomidou.mybatisplus.core.mapper.BaseMapper; import com.baomidou.mybatisplus.core.metadata.IPage; import com.baomidou.mybatisplus.core.toolkit.Constants; import com.baomidou.mybatisplus.extension.plugins.pagination.Page; import com.gblfy.springboot.mybatisplus.entity.User; import org.apache.ibatis.annotations.Param;import java.util.List;public interface UserMapper extends BaseMapper<User> {}

4.4. 啟動類加@MapperScan注解

import org.mybatis.spring.annotation.MapperScan;

@MapperScan("com.gblfy.springboot.mybatisplus.mapper")

4.5. 啟動類加@ComponentScan注解

import org.springframework.context.annotation.ComponentScan;

@ComponentScan("com.coderman.*")

注：掃描包，例如：掃描配置類上有@Configuration注解的類
