2.实体类：ChannelBaseVO.java,ChannelListVO.java

@Data可以直接建getset方法

package com.ysotek.wms.microservice.model.infrastructure.vo.tnb;

import com.ysotek.wms.microservice.model.infrastructure.vo.IChannelBaseVO;
import lombok.Data;

import java.util.Date;

/**
* Created by Cherry on 0013 13 十月.
*/
public @Data
class ChannelBaseVO implements IChannelBaseVO {
Long channelId;
String channelNameCn;
String parentOwnerName;
String channelTel;
String channelEmail;
String linkMan;
Date createDate;
}

package com.ysotek.wms.microservice.model.infrastructure.vo.tnb;

import com.ysotek.wms.microservice.model.infrastructure.vo.IChannelListVO;
import lombok.Data;

import java.util.Date;

/**
* Created by Cherry on 0012 12 十月.
*/
public @Data
class ChannelListVO implements IChannelListVO {
Long channelId;
String channelNameCn;
String channelNameEn;
String parentOwnerName;
boolean activityTrue;
String invoiceDesc;
Double feeRate;
String channelTel;
String channelFax;
String channelWeb;
String channelEmail;
String linkMan;
String channelProvince;
String channelCity;
String channelArea;
String channelAddress;
boolean channelTrue;
boolean consigneeTrue;
boolean deliverTrue;
String property;
Date createDate;
Date updateDate;

}

package com.ysotek.wms.microservice.model.infrastructure.vo;

/**
* Created by Cherry on 0013 13 十月.
*/
public interface IChannelBaseVO {

}

package com.ysotek.wms.microservice.model.infrastructure.vo;

/**
* Created by Cherry on 0012 12 十月.
*/
public interface IChannelListVO {
}

3.Dao数据层：ChannelListMapper.java

package com.ysotek.wms.microservice.infrastructure.mapper.impl.tnb;import com.ysotek.wms.microservice.infrastructure.mapper.impl.IChannelListMapper;import org.springframework.stereotype.Component;/*** Created by Cherry on 0012 12 十月.*/@Component("TnbChannelListMapper")public interface ChannelListMapper<T> extends IChannelListMapper<T> {}

package com.ysotek.wms.microservice.infrastructure.mapper.impl;import java.util.List;import java.util.Map;/*** Created by Cherry on 0012 12 十月.*/public interface IChannelListMapper<T> {List<T> getList(Map<String, Object> map);Long getCount(Map<String, Object> map);List<T> getChannelsList(Map<String, Object> map);}

4.service层ChannelServiceImpl.java

package com.ysotek.wms.microservice.infrastructure.service.impl.tnb;import com.ysotek.wms.microservice.core.model.PageModel;import com.ysotek.wms.microservice.infrastructure.mapper.impl.IChannelListMapper;import com.ysotek.wms.microservice.infrastructure.service.IChannelService;import com.ysotek.wms.microservice.model.infrastructure.vo.IChannelListVO;import org.springframework.beans.factory.annotation.Autowired;import org.springbeecframework.beans.factory.annotation.Qualifier;import org.springframework.stereotype.Service;import java.util.List;import java.util.Map;/*** Created by Cherry on 0012 12 十月.*/@Service("TnbChannelService")public class ChannelServiceImpl implements IChannelService{@Autowired@Qualifier(value = "TnbChannelListMapper")IChannelListMapper<IChannelListVO> channelListMapper;@Overridepublic PageModel queryChannels(Map<String, Object> map) {List result=channelListMapper.getList(map);Long total=channelListMapper.getCount(map);return new PageModel(total,result);}@Overridepublic List<IChannelListVO> queryChannelsList(Map<String, Object> map) {return channelListMapper.getChannelsList(map);}@Overridepublic void createChannel() {}}

package com.ysotek.wms.microservice.infrastructure.service.impl.tnb;import com.ysotek.wms.microservice.core.model.PageModel;import com.ysotek.wms.microservice.infrastructure.mapper.impl.IChannelListMapper;import com.ysotek.wms.microservice.infrastructure.service.IChannelService;import com.ysotek.wms.microservice.model.infrastructure.vo.IChannelListVO;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Qualifier;import org.springframework.stereotype.Service;import java.util.List;import java.util.Map;/*** Created by Cherry on 0012 12 十月.*/@Service("TnbChannelService")public class ChannelServiceImpl implements IChannelService{@Autowired@Qualifier(value = "TnbChannelListMapper")IChannelListMapper<IChannelListVO> channelListMapper;@Overridepublic PageModel queryChannels(Map<String, Object> map) {List result=channelListMapper.getList(map);Long total=channelListMapper.getCount(map);return new PageModel(total,result);}@Overridepublic List<IChannelListVO> queryChannelsList(Map<String, Object> map) {return channelListMapper.getChannelsList(map);}@Overridepublic void createChannel() {}}

5.Api控制层：InfrastructureAPI.java

package com.ysotek.wms.microservice.infrastructure.api;import com.ysotek.wms.microservice.core.logging.LogSource;import com.ysotek.wms.microservice.core.logging.WMSLogger;import com.ysotek.wms.microservice.core.model.ApiReturnModel;import com.ysotek.wms.microservice.core.model.PageModel;import com.ysotek.wms.microservice.infrastructure.service.IChannelService;import com.ysotek.wms.microservice.model.infrastructure.vo.IChannelListVO;import org.apache.commons.lang.StringUtils;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Qualifier;import org.springframework.web.bind.annotation.*;import java.util.HashMap;import java.util.List;import java.util.Map;@RestController@RequestMapping( path = {"/api/tnb/infrastructure", "/api/dev/infrastructure","/api/demo/infrastructure"})public class InfrastructureAPI {@Autowired@Qualifier(value = "TnbChannelService")IChannelService channelService;/***查询渠道商*/@RequestMapping(value = "/channel", method = {RequestMethod.GET})@ResponseBodypublic ApiReturnModel queryChannel(@RequestParam(required = false) Integer from,@RequestParam(required = false) Integer to,@RequestParam(required = false) Integer page,@RequestParam(required = false) Integer rows){WMSLogger.trace(LogSource.CHANNEL_QUERY,String.format("渠道商查询开始"));Map<String, Object> map = new HashMap<String, Object>();if (rows == null){rows = 20;}if (from == null){if (page == null){map.put("from",0);}else{from = (page - 1) * rows;map.put("from",from);}}else{map.put("from",from);}if (to == null){map.put("to",rows);}else{map.put("to",to);}PageModel result = channelService.queryChannels(map);WMSLogger.trace(LogSource.CHANNEL_QUERY,  String.format("渠道商查询结束，结果条数 %s",result.getTotalNum()));return new ApiReturnModel(200,result);}/*** 根据id或name查询渠道商* @param channelNameCn* @return*/@RequestMapping(value = "/channels", method = {RequestMethod.GET})@ResponseBodypublic ApiReturnModel queryChannelDetailByName(@RequestParam(required = false) String channelId,@RequestParam(required = false)  String channelNameCn){WMSLogger.trace(LogSource.CHANNEL_QUERY,String.format("单个渠道商查询开始,参数channelId:%s,channelNameCn:%s",channelId,channelNameCn));Map<String, Object> map = new HashMap<String, Object>();if (StringUtils.isNotBlank(channelId)){map.put("channelId", channelId);}if (StringUtils.isNotBlank(channelNameCn)){map.put("channelNameCn", "%"+channelNameCn+"%");}List<IChannelListVO> channelListVOList=channelService.queryChannelsList(map);if (channelListVOList == null){return new ApiReturnModel<String>(203,"订单不存在");}return new ApiReturnModel(200,channelListVOList);}@RequestMapping(method = {RequestMethod.POST})@ResponseBodypublic ApiReturnModel create(){return null;}}
