使用@JsonProperty将多个类似数据源写在一起
一、需求
原来已经有了自爬取的APP列表解析信息，现在增加一个渠道的APP列表，字段意思一样，但是字段名不一样。为了方便数据存储不变和下游部门代码不变，决定存储在一起，这就需要将字段映射成一样的。
二、实现
1、原来代码
package com.credithc.sea.entity.deviceinfo;
import com.fasterxml.jackson.annotation.JsonProperty;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
public class AppListInfo extends DeviceInfoBase {
private List apps = new ArrayList<>();
public List getApps() {
return apps;
}
public void setApps(List apps) {
if (apps == null)
this.apps = Collections.emptyList();
else
this.apps = apps;
}
public static class AppInfo {
@JsonProperty(value = "app_label")
private String appLabel; //App名称
@JsonProperty(value = "pkg_name")
private String pkgName; //App包名
@JsonProperty(value = "firstInstallTime")
private String firstInstallTime;
@JsonProperty(value = "lastUpdateTime")
private String lastUpdateTime;
public String getFirstInstallTime() {
return firstInstallTime;
}
public void setFirstInstallTime(String firstInstallTime) {
this.firstInstallTime = firstInstallTime;
}
public String getLastUpdateTime() {
return lastUpdateTime;
}
public void setLastUpdateTime(String lastUpdateTime) {
this.lastUpdateTime = lastUpdateTime;
}
public String getAppLabel() {
return appLabel;
}
public void setAppLabel(String appLabel) {
this.appLabel = appLabel;
}
public String getPkgName() {
return pkgName;
}
public void setPkgName(String pkgName) {
this.pkgName = pkgName;
}
@Override
public boolean equals(Object o) {
if (this == o) {
return true;
}
if (!(o instanceof AppInfo)) {
return false;
}
AppInfo appInfo = (AppInfo) o;
if (appLabel != null ? !appLabel.equals(appInfo.appLabel) : appInfo.appLabel != null) {
return false;
}
if (firstInstallTime != null ? !firstInstallTime.equals(appInfo.firstInstallTime) : appInfo.firstInstallTime != null) {
return false;
}
if (lastUpdateTime != null ? !lastUpdateTime.equals(appInfo.lastUpdateTime) : appInfo.lastUpdateTime != null) {
return false;
}
return pkgName != null ? pkgName.equals(appInfo.pkgName) : appInfo.pkgName == null;
}
@Override
public int hashCode() {
int result = appLabel != null ? appLabel.hashCode() : 0;
result = 31 * result + (pkgName != null ? pkgName.hashCode() : 0);
return result;
}
}
}
对应需要解析的数据是:
{
"params": {
"crawler_time": "2020-01-02 08:20:22",
"biz_channel": "API001",
"user_id": "0000000001",
"idCard": "证件号码",
"app_ver": "app_ver",
"biz_type": "ISS001",
"imei": "imei",
"crawler_type": "lend",
"type": "APP_LIST",
"apps": [
{
"app_label": "Solusindo",
"pkg_name": "com.ecreditpal.solusindo"
},
{
"app_label": "搜狗浏览器",
"pkg_name": "sogou.mobile.explorer"
}
]
}
}后来需要解析的是：
{
"params": {
"crawler_time": "2020-01-02 08:20:22",
"biz_channel": "API001",
"user_id": "0000000002",
"idCard": "证件号码",
"app_ver": "app_ver",
"biz_type": "ISS001",
"imei": "imei",
"crawler_type": "lend",
"type": "APP_LIST",
"apps": [
{
"app_name": "Solusindo",
"package_name": "com.ecreditpal.solusindo"
},
{
"app_label": "搜狗浏览器",
"pkg_name": "sogou.mobile.explorer"
}
]
}
}可以看到，APP名原来是app_label、pkg_name，新渠道是app_name、package_name，需要统一存储为app_label、pkg_name。
实现：
package com.credithc.sea.entity.deviceinfo;
import com.fasterxml.jackson.annotation.JsonProperty;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
public class AppListInfo extends DeviceInfoBase {
private List apps = new ArrayList<>();
public List getApps() {
return apps;
}
public void setApps(List apps) {
if (apps == null)
this.apps = Collections.emptyList();
else
this.apps = apps;
}
public static class AppInfo {
@JsonProperty(value = "app_label")
private String appLabel; //App名称
@JsonProperty(value = "pkg_name")
private String pkgName; //App包名
@JsonProperty(value = "firstInstallTime")
private String firstInstallTime;
@JsonProperty(value = "lastUpdateTime")
private String lastUpdateTime;
public String getFirstInstallTime() {
return firstInstallTime;
}
public void setFirstInstallTime(String firstInstallTime) {
this.firstInstallTime = firstInstallTime;
}
public String getLastUpdateTime() {
return lastUpdateTime;
}
public void setLastUpdateTime(String lastUpdateTime) {
this.lastUpdateTime = lastUpdateTime;
}
public String getAppLabel() {
return appLabel;
}
public void setAppLabel(String appLabel) {
this.appLabel = appLabel;
}
@JsonProperty(value = "app_name")
public void setAppName(String appName) {
this.appLabel = appName;
}
@JsonProperty(value ="package_name")
public void packageName(String packageName) {
this.pkgName = packageName;
}
public String getPkgName() {
return pkgName;
}
public void setPkgName(String pkgName) {
this.pkgName = pkgName;
}
@Override
public boolean equals(Object o) {
if (this == o) {
return true;
}
if (!(o instanceof AppInfo)) {
return false;
}
AppInfo appInfo = (AppInfo) o;
if (appLabel != null ? !appLabel.equals(appInfo.appLabel) : appInfo.appLabel != null) {
return false;
}
if (firstInstallTime != null ? !firstInstallTime.equals(appInfo.firstInstallTime) : appInfo.firstInstallTime != null) {
return false;
}
if (lastUpdateTime != null ? !lastUpdateTime.equals(appInfo.lastUpdateTime) : appInfo.lastUpdateTime != null) {
return false;
}
return pkgName != null ? pkgName.equals(appInfo.pkgName) : appInfo.pkgName == null;
}
@Override
public int hashCode() {
int result = appLabel != null ? appLabel.hashCode() : 0;
result = 31 * result + (pkgName != null ? pkgName.hashCode() : 0);
return result;
}
}
}
增加代码：
@JsonProperty(value = "app_name")
public void setAppName(String appName) {
this.appLabel = appName;
}
@JsonProperty(value ="package_name")
public void packageName(String packageName) {
this.pkgName = packageName;
}存数结果：
