1.idea+mybatis连接mySql自动生成代码,在pom.xml和application.xml的配置

在这里插入图片描述

需要配置三处。

1.pom.xml本次配置需要有

1.Springboot启动类
2.mybatis连接
3.mysql连接
4.swagger–用于后端数据展示接口
5.配置application.yml切换

        </profile>

    </profiles>


</project>

2.application.xml配置

在这里插入图片描述

2.1.application.yml

spring:
  profiles:
   active: dev2

2.2.application-dev.yml

server:
  port: 8088
  servlet:
    context-path: /dev
spring:
  datasource:
    url: jdbc:mysql://localhost:3306/bookdemo?useUnicode=true&characterEncoding=utf-8&useSSL=false&allowPublicKeyRetrieval=true
    username: root
    password: tiger
    driver-class-name: com.mysql.jdbc.Driver


mybatis:
  #驼峰命名
  map-underscore-to-camel-case: true
  #配置xml位置
  mapper-locations: classpath:mapping/*.xml
  #标注实体类位置
  type-aliases-package: com.example.springboot6.bean

3.generatorMapper.xml配置

自动生成mybatis和model代码

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE generatorConfiguration  PUBLIC
        "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
    <!--//驱动包存放的位子-->
    <classPathEntry location="D:\software\Idea\jarPackage\mysql-connector-java-8.0.15\mysql-connector-java-8.0.15.jar" />

    <context id="context" targetRuntime="MyBatis3">
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/bookdemo"
                        userId="root" password="tiger" >
        </jdbcConnection>

        <javaModelGenerator targetPackage="com.example.springboot6.bean" targetProject="src/main/java">
            <!--//实体存放的位子-->
            <property name="enableSubPackages" value="true"></property>
            <property name = "trimStrings" value="false"></property>
        </javaModelGenerator>

        <sqlMapGenerator targetPackage="com.example.springboot6.mapper"  targetProject="src/main/java" >

        </sqlMapGenerator>
        <javaClientGenerator type="XMLMAPPER" targetPackage="com.example.springboot6.mapper" targetProject="src/main/java" >
            <!--//实体存放的位子-->
            <property name="enableSubPackages" value="false"></property>
        </javaClientGenerator>

        <!--//表名和实体名-->
        <table tableName="book" domainObjectName="Book"
               enableCountByExample="false"
               enableUpdateByExample="false"
               enableDeleteByExample="false"
               enableSelectByExample="false"
               selectByExampleQueryId="false">
        </table>
        <table tableName="metadata" domainObjectName="Metadata"
               enableCountByExample="false"
               enableUpdateByExample="false"
               enableDeleteByExample="false"
               enableSelectByExample="false"
               selectByExampleQueryId="false">
        </table>
        <table tableName="type" domainObjectName="Type"
               enableCountByExample="false"
               enableUpdateByExample="false"
               enableDeleteByExample="false"
               enableSelectByExample="false"
               selectByExampleQueryId="false">
        </table>
    </context>
</generatorConfiguration>

完毕。
