代码生成器
hibernate mybatis 都是在做一件简化工作量的事情，重复简单的事情，认真做一次就可以，何必将宝贵时间花在不必要的事情上呢？？？
单表的增删改查，分页查询等，都是数据库表格建立以后需要做的操作，可是为重复的操作；
根据项目分析，可以抽取很多相同的部分，根据项目常用的功能书写demo；
pojo、vo生成的准备：
client，controller，service生成的准备：
其他的准备：
数据的准备过程:
/**
* 将对象信息存放找map的集合中
* @param basePackage
* @param db
* @param tableName
* @param className
* @param service
* @return
*/
private Map<String, Object> getRoot(String basePackage, String db, String tableName, String className, String service){
String lowerClassName =beanGenUtil.getLowerClassName(className);
Map<String, Object> root = new HashMap<>();
Map<String, Object> map = new HashMap<>();
map.put("table_name", tableName);
map.put("table_schema", db);
Map<String,Object> tableInfo=codeMapper.selectTableInfo(map);
List<Map<String, Object>> listResult = codeMapper.selectColumnsByTablename(map);
beanGenUtil.mapPutJavaType(listResult);
root.put("cols", listResult);
root.put("table", tableName);
root.put("className", className);
root.put("basepackage", basePackage);
root.put("tableInfo",tableInfo);
root.put("lowerClassName",lowerClassName);
root.put("service",service);
root.put("nowDate", DateTime.now().toString("yyyy-MM-dd"));
return root;
}
根据项目的分层代码生成主要有基础的pojo，读写的dao和对应的xml文件，以及单表增删改查的部分
下面展示的单表增删改查的ftl文件模板：
client层（微服务对外提供接口）
package com.${service}.client;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.cloud.netflix.feign.FeignClient;
import org.springframework.web.bind.annotation.*;
import javax.validation.Valid;
@FeignClient("${service}")
@Api(tags = "${tableInfo.TABLE_COMMENT} API文档")
public interface ${className}Client {
@ApiOperation(value = "新建 ${tableInfo.TABLE_COMMENT}")
@PostMapping(value = "/v1-0/${lowerClassName}/save")
Result<Long> save(@RequestBody @Valid ${className}SaveIVO ${lowerClassName}SaveIVO);
@ApiOperation(value = "更新 ${tableInfo.TABLE_COMMENT}")
@PostMapping(value = "/v1-0/${lowerClassName}/update")
Result<Integer> update(@RequestBody @Valid ${className}UpdateIVO ${lowerClassName}UpdateIVO);
@ApiOperation(value = "删除 ${tableInfo.TABLE_COMMENT}")
@PostMapping(value = "/v1-0/${lowerClassName}/delete/{${lowerClassName}Id}")
Result<Integer> delete(@PathVariable("${lowerClassName}Id") Long ${lowerClassName}Id);
@ApiOperation(value = "分页查询 ${tableInfo.TABLE_COMMENT}")
@GetMapping(value = "/v1-0/${lowerClassName}/query")
Result<PageData<${className}OVO>> query(@ModelAttribute("${lowerClassName}PageIVO") ${className}PageIVO ${lowerClassName}PageIVO);
}
controller层
package com.${service}.server.controller;
import com.${service}.client.${className}Client;
import com.${service}.common.vo.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;
import javax.validation.Valid;
@RestController
public class ${className}Controller extends BaseController implements ${className}Client {
@Autowired
private ${className}Service ${lowerClassName}Service;
@Override
public Result<Long> save(@RequestBody @Valid ${className}SaveIVO ${lowerClassName}SaveIVO){
Long data = ${lowerClassName}Service.save(${lowerClassName}SaveIVO);
return Result.ok(data);
}
@Override
public Result<Integer> update(@RequestBody @Valid ${className}UpdateIVO ${lowerClassName}UpdateIVO){
Integer data = ${lowerClassName}Service.update(${lowerClassName}UpdateIVO);
return Result.ok(data);
}
@Override
public Result<Integer> delete(@PathVariable("${lowerClassName}Id") Long ${lowerClassName}Id){
Integer data = ${lowerClassName}Service.delete(${lowerClassName}Id);
return Result.ok(data);
}
@Override
public Result<PageData<${className}OVO>> query(@ModelAttribute("${lowerClassName}PageIVO") ${className}PageIVO ${lowerClassName}PageIVO){
PageData<${className}OVO> data = ${lowerClassName}Service.query(${lowerClassName}PageIVO);
return Result.ok(data);
}
}
service层的部分
package com.${service}.server.service;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.BeanUtils;
import tk.mybatis.mapper.entity.Example;
import com.github.pagehelper.PageHelper;
import java.util.Date;
import java.util.List;
import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Service;
@Service
@Slf4j
public class ${className}Service extends BaseService {
@Autowired
private ${className}WriteMapper ${lowerClassName}WriteMapper;
@Autowired
private ${className}ReadMapper ${lowerClassName}ReadMapper;
public Long save(${className}SaveIVO ${lowerClassName}SaveIVO){
${className} saveBean = new ${className}();
BeanUtils.copyProperties(${lowerClassName}SaveIVO,saveBean);
//FIXME 对应的
int saveNum = ${lowerClassName}WriteMapper.insert(saveBean);
log.debug("新建，其影响条数是：{}",saveNum);
return saveBean.getId();
}
public PageData<${className}OVO> query(${className}PageIVO ${lowerClassName}PageIVO){
Example example = Example.builder(${className}.class).orderByAsc("createTime").build();
PageHelper.startPage(${lowerClassName}PageIVO.getPageNum(),${lowerClassName}PageIVO.getPageSize());
Example.Criteria criteria = example.createCriteria();
// criteria.andEqualTo("",);
//FIXME 添加查询条件
List<${className}> queryList = ${lowerClassName}ReadMapper.selectByExample(example);
return PageData.getCopyPageData(queryList,${className}.class,${className}OVO.class);
}
}
vo等相关的生成
package com.${service}.common.vo;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
import java.util.Date;
import java.math.BigDecimal;
/**
* ${tableInfo.TABLE_COMMENT}
* @Date ${nowDate}
*/
@Data
@ApiModel(value = "${tableInfo.TABLE_COMMENT}OVO")
public class ${className}OVO {
<#list cols as col>
<#if col.field != "isDelete" >
<#if col.COLUMN_COMMENT != "">
/**
* ${col.COLUMN_COMMENT}
*/
@ApiModelProperty(value = "${col.COLUMN_COMMENT}")
</#if>
private ${col.javaType} ${col.field};
</#if>
</#list>
}
基本上就是依样画葫芦。
