How to generate Code + paging plug-ins with mybatis-plus-gennretor Code Generator in spring
This article introduces the knowledge about "how to use mybatis-plus-gennertor code generator to generate code + paging plug-in" in spring. In the actual case operation process, many people will encounter such difficulties. Next, let Xiaobian lead you to learn how to deal with these situations! I hope you can read carefully and learn something!
code generator
1 Import the required jar package
com.baomidou mybatis-plus 2.3 junit junit 4.12 log4j log4j 1.2.17 com.mchange c3p0 0.9.5.2 mysql mysql-connector-java 5.1.37 org.springframework spring-context 4.3.10.RELEASE org.springframework spring-orm 4.3.10.RELEASE org.apache.velocity velocity-engine-core 2.0 org.slf4j slf4j-api 1.7.7 org.slf4j slf4j-log4j12 1.7.7
2 Configure applicationContext.xml
3 Database configuration
jdbc.driver=com.mysql.jdbc.Driverjdbc.url=jdbc:mysql://192.168.69.11:3306/shihaifengjdbc.username= username jdbc.password= password
4 Generating code
package com.shi.test;import com.baomidou.mybatisplus.enums.IdType;import com.baomidou.mybatisplus.generator.AutoGenerator;import com.baomidou.mybatisplus.generator.config.DataSourceConfig;import com.baomidou.mybatisplus.generator.config.GlobalConfig;import com.baomidou.mybatisplus.generator.config.PackageConfig;import com.baomidou.mybatisplus.generator.config.StrategyConfig;import com.baomidou.mybatisplus.generator.config.rules.DbType;import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;import org.junit.Test;/** * @author shfeng * @create 2019-07-18 16:59 * My Code Generator */public class MyGeneratorTest { @Test public void myGenerator(){ //1 Global Configuration GlobalConfig globalConfig = new GlobalConfig(); globalConfig.setActiveRecord(false) //Whether AR mode is supported .setAuthor("shiye") //Author .setOutputDir("D:\\project\\shiTest\\shi_Mybatis_Plus\\src\\main\\java") //Set generation path .setFileOverride(true) //file override .setIdType(IdType.AUTO) //Primary key policy auto-increment .setServiceName("%sService") //Set the name of the generated servo interface to remove the initial I .setBaseResultMap(true) //generate sql mapper mapping file .setBaseColumnList(true); //2 Database Configuration DataSourceConfig dataSourceConfig = new DataSourceConfig(); dataSourceConfig.setDbType(DbType.MYSQL) //Set database type .setDriverName("com.mysql.jdbc.Driver") //Set data driver .setUrl("jdbc:mysql://192.168.69.11:3306/shihaifeng") //Set database url .setUsername("") //Set user name .setPassword(""); //Set password //3 Policy Configuration StrategyConfig strategyConfig = new StrategyConfig(); strategyConfig.setCapitalMode(true) //global upper case naming .setDbColumnUnderline(true) //Specifies whether the table name field name is underlined .setNaming(NamingStrategy.underline_to_camel) //Naming method for mapping database tables to entities: hump naming method .setTablePrefix("") //Table prefix .setInclude("machine_item"); //table to be generated //4 Package Name Policy Configuration PackageConfig packageConfig = new PackageConfig(); packageConfig.setParent("com.shi") //global parent package .setController("controller") .setService("service") .setServiceImpl("service.impl") .setMapper("dao") //dao interface .setXml("dao") //mapper mapping file .setEntity("entity"); //5 Integrated Configuration AutoGenerator autoGenerator = new AutoGenerator(); autoGenerator.setGlobalConfig(globalConfig) .setDataSource(dataSourceConfig) .setStrategy(strategyConfig) .setPackageInfo(packageConfig); //6 Implementation autoGenerator.execute(); }}
paging plug-in
1. add configuration
(Method 1: mybatis-config.xml)
(Method 2: applicationContext.xml)
2. test
/** * Add pagination plug-ins Pagination using physical pagination * SELECT id AS id,name_cn AS nameCn,name_us AS nameUs,`desc`,created,creater,updater,updated * FROM machine_item LIMIT 0,1 */ @Test public void testQueryByPage(){ Page page = new Page(1,2); List list = machineItemMapper.selectPage(page, null); System.out.println(list); System.out.println("*************** System.out.println("Total ="+page.getTotal()); System.out.println("current page ="+page.getCurrent()); System.out.println("#of pages ="+page.getSize()); System.out.println("Total Pages ="+page.getPages()); page.setRecords(list); System.out.println("Total Records ="+page.getRecords()); }"Spring how to use mybatis-plus-gennetretor code generator to generate code + paging plug-in" content is introduced here, thank you for reading.
