1.創(chuàng)建Springboot項(xiàng)目
參考鏈接-如何使用IntelliJ IDEA創(chuàng)建Spring Boot項(xiàng)目
2.修改SpringBoot配置文件默認(rèn)application.properties 我習(xí)慣用application.yml 都可
server:
port: 8081
# context-path: /
#配置mysql數(shù)據(jù)源
spring:
datasource:
url: jdbc:mysql://127.0.0.1:3306/study?useUnicode=true&characterEncoding=utf-8&useSSL=false
driver-class-name: com.mysql.jdbc.Driver
username: 'root'
password: 'root'
#配置mybatis
mybatis:
mapper-locations: classpath*:/mappers/*Mapper.xml #注意：一定要對(duì)應(yīng)mapper映射xml文件的所在路徑
type-aliases-package: com.example.demo.domain # 注意：對(duì)應(yīng)實(shí)體類的路徑
# config-location: classpath:mapping/config/mybatis-config.xml
# configuration.map-underscore-to-camel-case: true
3.修改pom.xml文件
<!-- dependency-->
<!-- mybatis整合springboot的jar包 -->
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.3.2</version>
</dependency>
<!-- mysql -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>${mysql.version}</version>
<scope>runtime</scope>
</dependency>
<!--添加plugin-->
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.6</version>
<dependencies>
<!-- 需要注意dependency mysql-connector-java 直接寫在上面不好用-->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.38</version>
</dependency>
</dependencies>
<configuration>
<!-- 是否覆蓋邓嘹，true表示會(huì)替換生成的JAVA文件惧眠，false則不覆蓋 -->
<overwrite>true</overwrite>
</configuration>
</plugin>
4.mybatis-generator 配置文件
<?xml version="1.0" encoding="UTF-8"?>

<!-- 數(shù)據(jù)庫連接眼溶，直接通過${}讀取application.properties里的配置 -->
<jdbcConnection

<!-- table標(biāo)簽可以有多個(gè)，至少一個(gè)，tableName指定表名肮塞，可以使用_和%通配符 -->
<table tableName="record_entity">
<!-- 是否只生成POJO對(duì)象 -->
<property name="modelOnly" value="false"/>
<!-- 數(shù)據(jù)庫中表名有時(shí)我們都會(huì)帶個(gè)前綴襟齿，而實(shí)體又不想帶前綴，這個(gè)配置可以把實(shí)體的前綴去掉 -->
<domainObjectRenamingRule searchString="^" replaceString=""/>
