数据库表asm_log存放的是某金融机构所有自助机的操作日志：
CREATE TABLE `atm_log` (
`log_no` int(11) NOT NULL AUTO_INCREMENT COMMENT '日志编号',
`atm_no` varchar(32) NOT NULL COMMENT '自助机编号',
`card_id` varchar(32) NOT NULL COMMENT '卡号',
`operate_name` varchar(32) NOT NULL COMMENT '操作名称',
`operate_context` text COMMENT '操作内容',
`operate_time` datetime NOT NULL COMMENT '操作时间',
PRIMARY KEY (`log_no`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='自助机日志表';
表中数据如下：
现在要对自助机的日志进行统计分析，形式如下：
1、数据库表atm_log的实体类
package com.cn.demo.count.entity;
import java.io.Serializable;
import java.util.Date;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name = "atm_log")
public class AtmLog implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
@Id
@Column(name = "log_no")
private Integer logNo;
@Column(name = "atm_no")
private String atmNo;
@Column(name = "card_id")
private String cardId;
@Column(name = "operate_name")
private String operateName;
@Column(name = "operate_context")
private String operateContext;
@Column(name = "operate_time")
private Date operateTime;
public Integer getLogNo() {
return logNo;
}
public void setLogNo(Integer logNo) {
this.logNo = logNo;
}
public String getAtmNo() {
return atmNo;
}
public void setAtmNo(String atmNo) {
this.atmNo = atmNo;
}
public String getCardId() {
return cardId;
}
public void setCardId(String cardId) {
this.cardId = cardId;
}
public String getOperateName() {
return operateName;
}
public void setOperateName(String operateName) {
this.operateName = operateName;
}
public String getOperateContext() {
return operateContext;
}
public void setOperateContext(String operateContext) {
this.operateContext = operateContext;
}
public Date getOperateTime() {
return operateTime;
}
public void setOperateTime(Date operateTime) {
this.operateTime = operateTime;
}
}
有两种方式实现统计：
方法一：
2、创建一个用来访问统计结果的实体CountClass
package com.cn.demo.count.entity;
import java.io.Serializable;
public class CountClass implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
private String atmNo;
private String operateName;
private long count;
public CountClass(String atmNo, String operateName, long count) {
this.atmNo = atmNo;
this.operateName = operateName;
this.count = count;
}
public String getAtmNo() {
return atmNo;
}
public void setAtmNo(String atmNo) {
this.atmNo = atmNo;
}
public String getOperateName() {
return operateName;
}
public void setOperateName(String operateName) {
this.operateName = operateName;
}
public long getCount() {
return count;
}
public void setCount(long count) {
this.count = count;
}
}
3、接口层CountAtmLogRepository.java
package com.cn.demo.count.repository;
import java.util.Date;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import com.cn.demo.count.entity.AtmLog;
import com.cn.demo.count.entity.CountClass;
public interface CountAtmLogRepository extends JpaRepository{
@Query(value = "select new com.cn.demo.count.entity.CountClass(z.atmNo as atmNo, "
+ " z.operateName as operateName, count(z) as count) "
+ " from AtmLog z "
+ " where z.atmNo like %?1% and z.operateName like %?2% and z.operateTime>=?3 and z.operateTime<=?4 "
+ " group by z.operateName, z.atmNo")
public Page countLog(String atmNo, String operateName, Date startDate, Date endDate, Pageable pageable);
}
4、服务层CountAtmLogService.java
package com.cn.demo.count.service;
import java.util.Date;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.stereotype.Service;
import com.cn.demo.count.entity.CountClass;
import com.cn.demo.count.repository.CountAtmLogRepository;
@Service
public class CountAtmLogService {
@Autowired
private CountAtmLogRepository countAtmLogRepository;
public Page countLog(String atmNo, String operateName, Date startDate, Date endDate, Pageable pageable) {
Page list = countAtmLogRepository.countLog(atmNo, operateName, startDate, endDate, pageable);
return list;
}
}
5、控制层CountAtmLogController.java
package com.cn.demo.count.controller;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import com.cn.demo.count.entity.CountClass;
import com.cn.demo.count.service.CountAtmLogService;
@RestController
@RequestMapping("/count")
public class CountAtmLogController {
@Autowired
private CountAtmLogService service;
@RequestMapping(value = "/countLog", method = RequestMethod.GET)
public Page countLog(@RequestParam(value = "atmNo", required = false, defaultValue = "") String atmNo,
@RequestParam(value = "operateName", required = false, defaultValue = "") String operateName,
@RequestParam(value = "operateTime1", required = false, defaultValue = "") String operateTime1,
@RequestParam(value = "operateTime2", required = false, defaultValue = "") String operateTime2,
Pageable pageable){
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
if(operateTime1.equals("")) {
operateTime1 = "1999-01-01 00:00:00";
}
if(operateTime2.equals("")) {
operateTime2 = "2999-01-01 00:00:00";
}
Date startDate = null;
Date endDate = null;
Page list = null;
try {
startDate = sdf.parse(operateTime1);
endDate = sdf.parse(operateTime2);
list = service.countLog(atmNo, operateName, startDate, endDate, pageable);
}catch (ParseException e) {
e.printStackTrace();
}
return list;
}
}
运行程序，在浏览器地址栏输入http://localhost:9000/test/count/countLog?page=0&size=20
content中是查询到的内容
可以根据需要添加查询条件，例如：http://localhost:9000/test/count/countLog?atmNo=ATM001&operateName=存款&operateTime1=2019-10-15 15:29:00&operateTime2=2019-10-16 00:00:00&page=0&size=20。
方法二：
2、接口层AtmLogRepository.java
package com.cn.demo.count.repository;
import java.util.Date;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import com.cn.demo.count.entity.AtmLog;
public interface AtmLogRepository extends JpaRepository{
@Query(nativeQuery = true, value = "select z.atm_no as atmNo, z.operate_name as operateName,count(*) as count from atm_log z where z.atm_no like %?1% and z.operate_name like %?2% and z.operate_time>=?3 and z.operate_time <=?4 group by z.atm_no,z.operate_name")
Page countLog(String atmNo, String operateName, Date operateTime1, Date operateTime2, Pageable pageable);
}
3、服务层AtmLogService.java
package com.cn.demo.count.service;
import java.util.Date;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.stereotype.Service;
import com.cn.demo.count.repository.AtmLogRepository;
@Service
public class AtmLogService {
@Autowired
private AtmLogRepository atmLogRepository;
public Page countLog(String atmNo, String operateName, Date startDate, Date endDate, Pageable pageable) {
return atmLogRepository.countLog(atmNo, operateName, startDate, endDate, pageable);
}
}
4、控制层AtmLogController.java
package com.cn.demo.count.controller;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import com.cn.demo.count.service.AtmLogService;
@RestController
@RequestMapping("/api")
public class AtmLogController {
@Autowired
private AtmLogService atmLogService;
@RequestMapping(value = "/countLog", method = RequestMethod.GET)
public Page countLog(@RequestParam(value = "atmNo", required = false, defaultValue = "") String atmNo,
@RequestParam(value = "operateName", required = false, defaultValue = "") String operateName,
@RequestParam(value = "operateTime1", required = false, defaultValue = "") String operateTime1,
@RequestParam(value = "operateTime2", required = false, defaultValue = "") String operateTime2,
Pageable pageable){
if(operateTime1.equals("")) {
operateTime1 = "1999-01-01 00:00:00";
}
if(operateTime2.equals("")) {
operateTime2 = "2999-01-01 00:00:00";
}
Date startDate = null;
Date endDate = null;
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
try {
startDate = sdf.parse(operateTime1);
endDate = sdf.parse(operateTime2);
} catch (ParseException e) {
e.printStackTrace();
}
Page arr = atmLogService.countLog(atmNo, operateName, startDate, endDate, pageable);
return arr;
}
}
运行程序，在浏览器地址栏输入http://localhost:9000/test/api/countLog?page=0&size=20
content中是查询到的内容
可以根据需要添加查询条件，例如：http://localhost:9000/test/api/countLog?atmNo=ATM001&operateName=存款&operateTime1=2019-10-15 15:29:00&operateTime2=2019-10-16 00:00:00&page=0&size=20。
