MyBatisPlus代码生成器
一：引入依赖
<!--mybatisplus-->
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-boot-starter</artifactId>
<version>2.2.0</version>
</dependency>
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-support</artifactId>
<version>2.2.0</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.apache.velocity</groupId>
<artifactId>velocity-engine-core</artifactId>
<version>2.0</version>
</dependency>
<!--mysql-->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
<!--druid连接池-->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.1.9</version>
</dependency>二：resource下创建配置文件mybatisplus-config-system.properties
#代码输出基本路径
OutputDir=D:/JavaSoft/IdeaWorkSpace/Tencent-ymcc/ymcc-service/ymcc-service-system/src/main/java
#mapper.xmlSQL映射文件目录
OutputDirXml=D:/JavaSoft/IdeaWorkSpace/Tencent-ymcc/ymcc-service/ymcc-service-system/src/main/resources
#domain的输出路径
OutputDirBase=D:/JavaSoft/IdeaWorkSpace/Tencent-ymcc/ymcc-pojo/ymcc-pojo-system/src/main/java
#设置作者
author=yang
#自定义包路径:基础包的路径
parent=cn.ybl
#数据库连接信息
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql:///ymcc-system?serverTimezone=UTC
jdbc.user=root
jdbc.pwd=root三：MyBatisPlus注册分页插件
package cn.ybl.config;
import com.baomidou.mybatisplus.plugins.PaginationInterceptor;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.transaction.annotation.EnableTransactionManagement;
@Configuration
//@EnableTransactionManagement
@MapperScan("cn.ybl.mapper")
public class MyBatisPlusConfig {
/**
* 分页插件对象，MyBatisPlus需要手动注册此对象
* @return
*/
@Bean
public PaginationInterceptor paginationInterceptor(){
return new PaginationInterceptor();
}
}四：代码生成器主类
package cn.ybl;
import com.baomidou.mybatisplus.generator.AutoGenerator;
import com.baomidou.mybatisplus.generator.InjectionConfig;
import com.baomidou.mybatisplus.generator.config.*;
import com.baomidou.mybatisplus.generator.config.converts.MySqlTypeConvert;
import com.baomidou.mybatisplus.generator.config.po.TableInfo;
import com.baomidou.mybatisplus.generator.config.rules.DbType;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;
import java.util.*;
/**
* 生成代码的主类
*/
public class GenteratorCode {
public static void main(String[] args) throws InterruptedException {
//用来获取Mybatis-Plus.properties文件的配置信息
ResourceBundle rb = ResourceBundle.getBundle("mybatisplus-config-system"); //不要加后缀
AutoGenerator mpg = new AutoGenerator();
// 全局配置
GlobalConfig gc = new GlobalConfig();
gc.setOutputDir(rb.getString("OutputDir"));
gc.setFileOverride(false);
gc.setActiveRecord(true);// 开启 activeRecord 模式
gc.setEnableCache(false);// XML 二级缓存
gc.setBaseResultMap(true);// XML ResultMap
gc.setBaseColumnList(false);// XML columList
gc.setAuthor(rb.getString("author"));
mpg.setGlobalConfig(gc);
// 数据源配置
DataSourceConfig dsc = new DataSourceConfig();
dsc.setDbType(DbType.MYSQL);
dsc.setTypeConvert(new MySqlTypeConvert());
dsc.setDriverName(rb.getString("jdbc.driver"));
dsc.setUsername(rb.getString("jdbc.user"));
dsc.setPassword(rb.getString("jdbc.pwd"));
dsc.setUrl(rb.getString("jdbc.url"));
mpg.setDataSource(dsc);
// 表策略配置
StrategyConfig strategy = new StrategyConfig();
strategy.setTablePrefix(new String[] { "t_" });// 此处可以修改为您的表前缀
strategy.setNaming(NamingStrategy.underline_to_camel);// 表名生成策略
strategy.setInclude(new String[]{
"t_config",
"t_department",
"t_employee",
"t_operation_log",
"t_systemdictionary",
"t_systemdictionaryitem"
}); // 需要生成的表
mpg.setStrategy(strategy);
// 包配置
PackageConfig pc = new PackageConfig();
pc.setParent(rb.getString("parent")); //cn.ybl.
pc.setController("web.controller"); //cn.ybl.web.controller
pc.setService("service");
pc.setServiceImpl("service.impl");
pc.setEntity("domain");
pc.setMapper("mapper");
mpg.setPackageInfo(pc);
// 注入自定义配置，可以在 VM 中使用 cfg.abc 【可无】
InjectionConfig cfg = new InjectionConfig() {
@Override
public void initMap() {
Map<String, Object> map = new HashMap<String, Object>();
map.put("abc", this.getConfig().getGlobalConfig().getAuthor() + "-rb");
this.setMap(map);
}
};
List<FileOutConfig> focList = new ArrayList<FileOutConfig>();
//controller的输出配置
focList.add(new FileOutConfig("/templates/controller.java.vm") {
@Override
public String outputFile(TableInfo tableInfo) {
//合并好的内容输出到哪儿？
return rb.getString("OutputDir")+ "/cn/ybl/web/controller/" + tableInfo.getEntityName() + "Controller.java";
}
});
//query的输出配置
focList.add(new FileOutConfig("/templates/query.java.vm") {
@Override
public String outputFile(TableInfo tableInfo) {
return rb.getString("OutputDirBase")+ "/cn/ybl/query/" + tableInfo.getEntityName() + "Query.java";
}
});
// 调整 domain 生成目录演示
focList.add(new FileOutConfig("/templates/entity.java.vm") {
@Override
public String outputFile(TableInfo tableInfo) {
return rb.getString("OutputDirBase")+ "/cn/ybl/domain/" + tableInfo.getEntityName() + ".java";
}
});
// 调整 xml 生成目录演示
focList.add(new FileOutConfig("/templates/mapper.xml.vm") {
@Override
public String outputFile(TableInfo tableInfo) {
return rb.getString("OutputDirXml")+ "/cn/ybl/mapper/" + tableInfo.getEntityName() + "Mapper.xml";
}
});
cfg.setFileOutConfigList(focList);
mpg.setCfg(cfg);
// 自定义模板配置，可以 copy 源码 mybatis-plus/src/main/resources/templates 下面内容修改，
// 放置自己项目的 src/main/resources/templates 目录下, 默认名称一下可以不配置，也可以自定义模板名称
TemplateConfig tc = new TemplateConfig();
tc.setService("/templates/service.java.vm");
tc.setServiceImpl("/templates/serviceImpl.java.vm");
tc.setMapper("/templates/mapper.java.vm");
tc.setEntity(null);
tc.setController(null);
tc.setXml(null);
// 如上任何一个模块如果设置 空 OR Null 将不生成该模块。
mpg.setTemplate(tc);
// 执行生成
mpg.execute();
}
}五：因为MyBatisPlus自带的Controller模板并不友好，自定义一个模板controller.java.vm，放在resource/templates下
package ${package.Controller};
import ${package.Service}.${table.serviceName};
import ${package.Entity}.${entity};
import cn.ybl.query.${entity}Query;
import cn.ybl.result.JSONResult;
import cn.ybl.result.PageList;
import com.baomidou.mybatisplus.plugins.Page;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
@RestController
@RequestMapping("/${table.entityPath}")
public class ${entity}Controller {
@Autowired
public ${table.serviceName} ${table.entityPath}Service;
/**
* 保存和修改公用的
*/
@RequestMapping(value="/save",method= RequestMethod.POST)
public JSONResult saveOrUpdate(@RequestBody ${entity} ${table.entityPath}){
if(${table.entityPath}.getId()!=null){
${table.entityPath}Service.updateById(${table.entityPath});
}else{
${table.entityPath}Service.insert(${table.entityPath});
}
return JSONResult.success();
}
/**
* 删除对象
*/
@RequestMapping(value="/{id}",method=RequestMethod.DELETE)
public JSONResult delete(@PathVariable("id") Long id){
${table.entityPath}Service.deleteById(id);
return JSONResult.success();
}
/**
* 获取对象
*/
@RequestMapping(value = "/{id}",method = RequestMethod.GET)
public JSONResult get(@PathVariable("id")Long id){
return JSONResult.success(${table.entityPath}Service.selectById(id));
}
/**
* 查询所有对象
*/
@RequestMapping(value = "/list",method = RequestMethod.GET)
public JSONResult list(){
return JSONResult.success(${table.entityPath}Service.selectList(null));
}
/**
* 带条件分页查询数据
*/
@RequestMapping(value = "/pagelist",method = RequestMethod.POST)
public JSONResult page(@RequestBody ${entity}Query cn.ybl.query){
Page<${entity}> page = new Page<${entity}>(cn.ybl.query.getPage(),cn.ybl.query.getRows());
page = ${table.entityPath}Service.selectPage(page);
return JSONResult.success(new PageList<${entity}>(page.getTotal(),page.getRecords()));
}
}六：自定义一个query模板query.java.vm
package ${package.query};
/**
* @author ${author}
* @since ${date}
*/
public class ${table.entityName}Query extends BaseQuery{
}更改数据库表和配置信息，启动主类即可
