简介

前面个已经讲过mybatis的批量更新操作。批量操作还有时分页查询，针对项目的完善性，来讲解一下分页工具的植入pagerHelper和tk.mybatis使用。其实官网已经有具体代码，代价有空可以多多参考官网操作。链接地址MyBatis-Spring-Boot

技术方案

maven jar导入

查看官方说明引入依赖，如下：

<!--mybatis-->
<dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>1.3.1</version>
</dependency>
<!--mapper-->
<dependency><groupId>tk.mybatis</groupId><artifactId>mapper-spring-boot-starter</artifactId><version>1.2.4</version>
</dependency>
<!--pagehelper-->
<dependency><groupId>com.github.pagehelper</groupId><artifactId>pagehelper-spring-boot-starter</artifactId><version>1.2.3</version>
</dependency>

maven plugin配置

引入完jar依赖之后，配置plugin插件，插件时根据maven来识别的，可以直接拷贝官网的配置即可，如下：

 <plugin><groupId>org.mybatis.generator</groupId><artifactId>mybatis-generator-maven-plugin</artifactId><version>1.3.2</version><configuration><configurationFile>${basedir}/src/main/resources/generator/generatorConfig.xml</configurationFile><overwrite>true</overwrite><verbose>true</verbose></configuration><dependencies><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>${mysql.version}</version></dependency><dependency><groupId>tk.mybatis</groupId><artifactId>mapper-generator</artifactId><version>1.0.0</version></dependency></dependencies></plugin>

配置generatorConfig.xml

根据自己喜欢，可以定制化配置generatorConfig.xml，下面是我个人基本配置，更多配置说明，请查看官方说明MyBatis Generator 详解

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfigurationPUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN""http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"><generatorConfiguration><properties resource="generator/application-dev.properties"/><context id="Mysql" targetRuntime="MyBatis3Simple" defaultModelType="flat"><property name="beginningDelimiter" value="`"/><property name="endingDelimiter" value="`"/><plugin type="tk.mybatis.mapper.generator.MapperPlugin"><property name="mappers" value="com.lgh.common.util.MyMapper"/></plugin><jdbcConnection driverClass="${spring.datasource.driver-class-name}"connectionURL="${spring.datasource.url}"userId="${spring.datasource.username}"password="${spring.datasource.password}"></jdbcConnection><javaModelGenerator targetPackage="com.lgh.model" targetProject="src/main/java"/><sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources"/><javaClientGenerator targetPackage="com.lgh.mapper" targetProject="src/main/java"type="XMLMAPPER"/><!-- 数据库表 以及实体类命名 --><!-- <table schema="CL_DEMO" tableName="tb_user" domainObjectName="User"enableCountByExample="false" enableDeleteByExample="false"enableSelectByExample="false" enableUpdateByExample="false"selectByExampleQueryId="false" /><table schema="CL_DEMO" tableName="tb_role" domainObjectName="Role"enableCountByExample="false" enableDeleteByExample="false"enableSelectByExample="false" enableUpdateByExample="false"selectByExampleQueryId="false" /><table schema="CL_DEMO" tableName="tb_menu" domainObjectName="Menu"enableCountByExample="false" enableDeleteByExample="false"enableSelectByExample="false" enableUpdateByExample="false"selectByExampleQueryId="false" /><table schema="CL_DEMO" tableName="tb_resource" domainObjectName="Resource"enableCountByExample="false" enableDeleteByExample="false"enableSelectByExample="false" enableUpdateByExample="false"selectByExampleQueryId="false" /><table schema="CL_DEMO" tableName="user_role" domainObjectName="UserRole"enableCountByExample="false" enableDeleteByExample="false"enableSelectByExample="false" enableUpdateByExample="false"selectByExampleQueryId="false" /><table schema="CL_DEMO" tableName="role_menu" domainObjectName="RoleMenu"enableCountByExample="false" enableDeleteByExample="false"enableSelectByExample="false" enableUpdateByExample="false"selectByExampleQueryId="false" /><table schema="CL_DEMO" tableName="menu_resource" domainObjectName="MenuResource"enableCountByExample="false" enableDeleteByExample="false"enableSelectByExample="false" enableUpdateByExample="false"selectByExampleQueryId="false" /><table schema="CL_DEMO" tableName="role_resource" domainObjectName="RoleResource"enableCountByExample="false" enableDeleteByExample="false"enableSelectByExample="false" enableUpdateByExample="false"selectByExampleQueryId="false" /><table schema="CL_DEMO" tableName="logon" domainObjectName="Logon"enableCountByExample="false" enableDeleteByExample="false"enableSelectByExample="false" enableUpdateByExample="false"selectByExampleQueryId="false" />--></context>
