springboot搭建mybatis框架

从数据库反向生成model,mapper,xml映射文件

1）安装mybatis_generator插件

<build>
<plugins>
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.5</version>
<configuration>
<configurationFile>src/main/resources//generatorConfig.xml</configurationFile>
<overwrite>true</overwrite>
<verbose>true</verbose>
</configuration>
<dependencies>
<!-- https://mvnrepository.com/artifact/org.springframework/spring-jdbc -->                    <dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-core</artifactId>
<version>1.3.5</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>6.0.6</version>
</dependency>
</dependencies>
</plugin>
</plugins>
</build>

这样插件就配置好了

2）generator文件

<?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>

<context id="DB2Tables" targetRuntime="MyBatis3">
<commentGenerator>
<property name="suppressDate" value="true"/>
<property name="suppressAllComments" value="true"/>
</commentGenerator>
<!--数据库链接地址账号密码-->
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://127.0.0.1:3306/spring"
userId="root"
password="116368">
</jdbcConnection>
<javaTypeResolver>
<property name="forceBigDecimals" value="false"/>
</javaTypeResolver>
<!--生成Model类存放位置-->
<javaModelGenerator targetPackage="com.example.demo.model" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
<property name="trimStrings" value="true"/>
</javaModelGenerator>
<!--生成映射文件存放位置-->
<sqlMapGenerator targetPackage="com.example.demo.sqlmap" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
</sqlMapGene

rator>
<!--生成Dao类存放位置-->
<javaClientGenerator type="XMLMAPPER" targetPackage="com.example.demo.map" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
</javaClientGenerator>
<!--生成对应表及类名-->
<table tableName="test" schema="spring" domainObjectName="Test">
<generatedKey column="id" sqlStatement="MySql" identity="true"/>
</table>
<!--<table tableName="message" domainObjectName="Messgae" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>-->
</context>
</generatorConfiguration>

至此，忘了一件事，generatorConfig.xml最后有个建表的，我们要手动在数据库中新建一个表，要有表结构，就结束了
