好久记录笔记,这段时间做政府的项目,数据录入系统基本都是通过excel导入,且数据量大,许多也是单表的录入,这就有很多可以通用的代码,如controller,service层的那一套都是可以代码生成,添加了一个数据库批量添加接口(目前只支持oracle),代码是基于mybatis-generator-1.3.5源码修改后的,具体的源码解析,后面等项目上线后,再好好整理一下,这里就粗鲁的记录如何使用。
1:mybatis-generator.xml 配置文件
- <?xml version="1.0" encoding="UTF-8"?>

- <property name="enableInsertBatchIgnore" value="createDt"></property>
- </table>
- </context>
- </generatorConfiguration>
2:执行生成代码
2-1:最后生成 InsertBatch
- <insert id="insertBatch" parameterType="java.util.List">
- insert into FIXED_ASSETS_INDICATOR (ID, ORDER_MARK, COUNT_TIME,
- CITY, CITY_CODE, FIXED_INVESTMENT_TOTAL,
- FIXED_INVESTMENT_SPEED_UP, FOLK_INVESTMENT_TOTAL,
- FOLK_INVESTMENT_SPEED_UP, REALTY_INVESTMENT_TOTAL,
- REALTY_INVESTMENT_SPEED_UP, EMPLOYMENT_INVESTMENT_TOTAL,
- EMPLOYMENT_INVESTMENT_SPEED_UP, TECHNOLOGY_INVESTMENT_TOTAL,
- TECHNOLOGY_INVESTMENT_SPEED_UP, INFRASTRUCTURE_TOTAL,
- INFRASTRUCTURE_SPEED_UP, HIGH_TECH_TOTAL,
- HIGH_TECH_SPEED_UP, MANUFACTURING_TOTAL,
- MANUFACTURING_SPEED_UP)
- <foreach close=")" collection="list" item="item" open="(" separator="UNION">
- SELECT #{item.id,jdbcType=VARCHAR}, #{item.orderMark,jdbcType=DECIMAL}, #{item.countTime,jdbcType=TIMESTAMP},
- #{item.city,jdbcType=VARCHAR}, #{item.cityCode,jdbcType=VARCHAR}, #{item.fixedInvestmentTotal,jdbcType=DECIMAL},
- #{item.fixedInvestmentSpeedUp,jdbcType=FLOAT}, #{item.folkInvestmentTotal,jdbcType=DECIMAL},
- #{item.folkInvestmentSpeedUp,jdbcType=FLOAT}, #{item.realtyInvestmentTotal,jdbcType=DECIMAL},
- #{item.realtyInvestmentSpeedUp,jdbcType=FLOAT}, #{item.employmentInvestmentTotal,jdbcType=DECIMAL},
- #{item.employmentInvestmentSpeedUp,jdbcType=FLOAT}, #{item.technologyInvestmentTotal,jdbcType=DECIMAL},
- #{item.technologyInvestmentSpeedUp,jdbcType=FLOAT}, #{item.infrastructureTotal,jdbcType=DECIMAL},
- #{item.infrastructureSpeedUp,jdbcType=FLOAT}, #{item.highTechTotal,jdbcType=DECIMAL},
- #{item.highTechSpeedUp,jdbcType=FLOAT}, #{item.manufacturingTotal,jdbcType=DECIMAL},
- #{item.manufacturingSpeedUp,jdbcType=FLOAT} FROM DUAL
- </foreach>
- </insert>
2-2:生成service
- public class FixedAssetsIndicatorServiceImpl implements FixedAssetsIndicatorService {
- @Autowired
- private FixedAssetsIndicatorMapper fixedAssetsIndicatorMapper;
- public int insertBatch(List<FixedAssetsIndicator> list) {
- if(list != null && list.size() > 0 ){
- FixedAssetsIndicatorExample fixedAssetsIndicatorExample = new FixedAssetsIndicatorExample();
- fixedAssetsIndicatorExample.createCriteria().andCountTimeEqualTo(list.get(0).getCountTime());
- fixedAssetsIndicatorMapper.deleteByExample(fixedAssetsIndicatorExample);
- return fixedAssetsIndicatorMapper.insertBatch(list);
- }
- return 0;
- }
- public PageInfo<FixedAssetsIndicator> list(ListFixedAssetsIndicatorParam param) {
- FixedAssetsIndicatorExample example = new FixedAssetsIndicatorExample();
- if(param.getCountTime() != null){
- example.createCriteria().andCountTimeEqualTo(param.getCountTime());
- }
- PageHelper.startPage(param.getPageNum(), param.getPageSize());
- example.setOrderByClause("ORDER_MARK");
- List<FixedAssetsIndicator> fromDB = fixedAssetsIndicatorMapper.selectByExample(example);

- return pageInfo;
- }

- return fixedAssetsIndicatorMapper.selectByPrimaryKey(id);
- }
- public void save(FixedAssetsIndicator toDB) {

- }
- public void delete(String id) {
- fixedAssetsIndicatorMapper.deleteByPrimaryKey(id);
- }
- public void update(FixedAssetsIndicator toDB) {
- fixedAssetsIndicatorMapper.updateByPrimaryKeySelective(toDB);
- }
- }
2-3:生成controller:添加excel导入导出接口(基于easypoi导入导出)
