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"?>

</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,

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.technologyInvestmentSpeedUp,jdbcType=FLOAT}, #{item.infrastructureTotal,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);
PageInfo pageInfo = new PageInfo(fromDB);
return pageInfo;
}
public FixedAssetsIndicator get(String id) {
return fixedAssetsIndicatorMapper.selectByPrimaryKey(id);
}
public void save(FixedAssetsIndicator toDB) {
fixedAssetsIndicatorMapper.insertSelective(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)
