一、

1. pom

<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.2.5.RELEASE</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.gblfy</groupId><artifactId>springboot-mybatisplus</artifactId><version>0.0.1-SNAPSHOT</version><name>springboot-mybatisplus</name><description>Demo project for Spring Boot</description><properties><java.version>1.8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><scope>runtime</scope></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency><!--Mybatis-Plus 啟動器--><dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-boot-starter</artifactId><version>3.3.1.tmp</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><!-- https://mvnrepository.com/artifact/org.jmock/jmock-junit4 --><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.13</version><scope>test</scope></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins><resources><resource><directory>src/main/resources</directory><filtering>true</filtering></resource><resource><directory>src/main/java</directory><includes><include>**/*.xml</include></includes></resource></resources></build></project>

2. application.yml

#數據庫庫配置信息 spring:datasource:driver-class-name: com.mysql.cj.jdbc.Driverurl: jdbc:mysql://localhost:3306/ssm?useSSL=false&serverTimezone=GMT%2B8username: rootpassword: root#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# 日志級別 日志內容 換行 logging:level:root: warncom.gblfy.springboot.mybatisplus.mapper: tracepattern:console: '%p%m%n'

3. dao層接口集成baseMapper

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. 啟動類上+掃描

package com.gblfy.springboot.mybatisplus;import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication @MapperScan("com.gblfy.springboot.mybatisplus.mapper") public class SpringbootMybatisplusApplication {public static void main(String[] args) {SpringApplication.run(SpringbootMybatisplusApplication.class, args);} }

5. 創建數據庫

數據庫名：ssm
編碼：utf-8

6. 初始化表結構

/*Navicat Premium Data TransferSource Server : 127.0.0.1Source Server Type : MySQLSource Server Version : 50721Source Host : 127.0.0.1:3306Source Schema : ssmTarget Server Type : MySQLTarget Server Version : 50721File Encoding : 65001Date: 14/03/2020 20:23:26 */SET NAMES utf8mb4; SET FOREIGN_KEY_CHECKS = 0;-- ---------------------------- -- Table structure for user -- ---------------------------- DROP TABLE IF EXISTS `user`; CREATE TABLE `user` (`id` bigint(20) NOT NULL COMMENT '主鍵ID',`name` varchar(30) CHARACTER SET utf8 COLLATE utf8_bin NULL DEFAULT NULL COMMENT '姓名',`age` int(11) NULL DEFAULT NULL COMMENT '年齡',`email` varchar(50) CHARACTER SET utf8 COLLATE utf8_bin NULL DEFAULT NULL COMMENT '郵箱',PRIMARY KEY (`id`) USING BTREE ) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_bin ROW_FORMAT = Dynamic;-- ---------------------------- -- Records of user -- ---------------------------- INSERT INTO `user` VALUES (1, 'Jone', 18, 'test1@baomidou.com'); INSERT INTO `user` VALUES (2, 'Jack', 20, 'test2@baomidou.com'); INSERT INTO `user` VALUES (3, 'Tom', 28, 'test3@baomidou.com'); INSERT INTO `user` VALUES (4, '郭軒', 26, 'test4@baomidou.com'); INSERT INTO `user` VALUES (5, '郭振', 26, 'test5@baomidou.com'); INSERT INTO `user` VALUES (1238735228017610754, '郭雨昕', 2, 'gblfy@qq.com'); INSERT INTO `user` VALUES (1238735794525503489, '郭雨澤', 22, 'gblfy@qq.com');SET FOREIGN_KEY_CHECKS = 1;

7. 瀏覽器驗證

http://localhost:8080/user/queryList

8. 源碼地址

https://github.com/gb-heima/springboot-mybatisplus
