使用Mybatis generator生成代码

环境信息

构建工具为Maven

数据库为MySQL

准备pom.xml

<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion>
<groupId>my.test</groupId>
<artifactId>mybatis</artifactId>
<version>1.0.0</version>

<build>
<plugins>

<dependencies>
<dependency>

</dependency>
</dependencies>

<configuration>
<configurationFile>${basedir}/src/main/resources/generatorConfig.xml</configurationFile>
</configuration>
</plugin>
</plugins>
</build>
</project>

configurationFile可以不指定，默认就是${basedir}/src/main/resources/generatorConfig.xml

准备generatorConfig.xml

<?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="servicesupport" targetRuntime="MyBatis3">
<property name="javaFileEncoding" value="UTF-8" />

<jdbcConnection connectionURL="jdbc:mysql://10.23.0.79:3306/servicesupport"
driverClass="com.mysql.jdbc.Driver" password="location" userId="location" />

<javaModelGenerator targetPackage="my.test.mybatis.model" targetProject="MAVEN" />

<sqlMapGenerator targetPackage="mybatis" targetProject="MAVEN" />

<javaClientGenerator targetPackage="my.test.mybatis.persist" targetProject="MAVEN" type="XMLMAPPER" />

<table tableName="t_safe_apkrightlist_bak" domainObjectName="ApkRightlistBak">
<generatedKey column="id" sqlStatement="JDBC" identity="true" />
</table>

</context>
</generatorConfiguration>

在Maven工程中将targetProject设置为MAVEN有特殊含义，表示生成的代码会放在MAVEN的target目录中，且会自动生成targetPackage指定的目录结构

执行mvn mybatis-generator:generate

业务代码

ApkRightlistBakMapper apkRightlistBakMapper = sqlTemplate.getMapper(ApkRightlistBakMapper.class);

ApkRightlistBakExample apkRightlistBakExample = new ApkRightlistBakExample();
apkRightlistBakExample.or().andApknameEqualTo("xxx").andTypeEqualTo(1);
apkRightlistBakExample.or().andApknameEqualTo("yyy").andTypeEqualTo(2);
apkRightlistBakExample.setOrderByClause("id asc");

List<ApkRightlistBakWithBLOBs> apkRightlistBakWithBLOBsList = apkRightlistBakMapper.selectByExampleWithBLOBs(apkRightlistBakExample);
