springboot整合mybatis逆向工程

1.添加依赖
<!--mysql依赖-->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>

<!-- SpringBoot - MyBatis -->
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.3.1</version>
</dependency>

<!-- SpringBoot - MyBatis 逆向工程 -->
<dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-core</artifactId>
<version>1.3.5</version>
</dependency>

2.添加插件<!-- MyBatis 逆向工程 插件 -->
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.5</version>
<configuration>
<!--允许移动生成的文件 -->
<verbose>true</verbose>
<!-- 是否覆盖 -->
<overwrite>true</overwrite>
</configuration>

<dependencies>
<dependency>
<groupId> mysql</groupId>
<artifactId> mysql-connector-java</artifactId>
<version>5.1.30</version>
</dependency>
</dependencies>
</plugin>3.application配置mysql连接
spring:
datasource:
driver-class-name: com.mysql.jdbc.Driver
url: jdbc:mysql://127.0.0.1:3306/wechat
username: root
password: root4.generatorConfig.xml配置文件<?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">
<!--去掉注释-->
<commentGenerator>
<property name="suppressAllComments" value="true"/>
</commentGenerator>
<!--需要配置数据库连接-->
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://****:3306/competition?characterEncoding=utf-8&useSSL=false"
userId="****"
password="****">
</jdbcConnection>
<javaTypeResolver >
<property name="forceBigDecimals" value="false" />
</javaTypeResolver>

<!--指定entity生成的位置-->
<javaModelGenerator targetPackage="com.example.competition.dao.entity" targetProject="./src/main/java">
<property name="enableSubPackages" value="true" />
<property name="trimStrings" value="true" />
</javaModelGenerator>

<!--sql映射文件生成的位置 mapper.xml-->
<sqlMapGenerator targetPackage="mapper" targetProject="./src/main/resources">
<property name="enableSubPackages" value="true" />
</sqlMapGenerator>

<!--指定DaoMapper生成的位置 mapper.java-->
<javaClientGenerator type="XMLMAPPER" ta
c90c
rgetPackage="com.example.competition.dao.mapper" targetProject="./src/main/java">
<property name="enableSubPackages" value="true" />
</javaClientGenerator>

<!--table是指定每个表的生成策略-->
<!--<table tableName="department" domainObjectName="Department"></table>-->
<!--<table tableName="group_teacher_rel" domainObjectName="Group_teacher_rel"></table>-->
<!--<table tableName="groups" domainObjectName="Groups"></table>-->
<!--<table tableName="specialty" domainObjectName="Specialty"></table>-->
<!--<table tableName="student" domainObjectName="Student"></table>-->
<!--<table tableName="teacher" domainObjectName="Teacher"></table>-->
<table tableName="test" domainObjectName="Test"></table>
</context>
</generatorConfiguration>
5.启动类Generator

public class Generator {
public static void main(String[] args){
List<String> warnings = new ArrayList<>();
boolean overwrite = true;
String genCfg = "/generatorConfig.xml";
File configFile = new File(Generator.class.getResource(genCfg).getFile());
ConfigurationParser cp = new ConfigurationParser(warnings);
Configuration config = null;
try {
config = cp.parseConfiguration(configFile);
} catch (IOException e) {
e.printStackTrace();
} catch (XMLParserException e) {
e.printStackTrace();
}
DefaultShellCallback callback = new DefaultShellCallback(overwrite);
MyBatisGenerator myBatisGenerator = null;
try {
myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
} catch (InvalidConfigurationException e) {
e.printStackTrace();
}
try {
myBatisGenerator.generate(null);
} catch (SQLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}

1.springboot，mybatis 开启驼峰转换
