比如我httpclient调用的接口返回的格式是这样的：
一：data里是个对象
{
"code": 200,
"message": "执行成功",
"data": {
"userId": 1,
"userName": "Jamie",
"roles": "admin",
"realName": "测试人员",
"tel": "13651046002",
"email": "12345@qq.com",
"enabled": true
}
}
1.添加pom依赖
<!--集成lombok-->
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<optional>true</optional>
</dependency>
<!-- 集成json-->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
<version>1.2.58</version>
</dependency>
2.定义一个返回报文实体
/**
* @author: sujing
* @version: 1.0.0
* @ClassName: Return.java
* @date: 2019/10/11 16:24
* 返回报文封装
*/
@Data
public class Return<T> {
String code;
String message;
T data;
public Return() {
}
public Return(String code, String message) {
this.code = code;
this.message = message;
}
public Return(String code, String message, T data) {
this.code = code;
this.message = message;
this.data = data;
}
}
3.解析httpclient返回的参数
//httpClient调用接口，返回String字符串
String httpClientReturn = HttpClientUtil.get("http://xxxxx:9099/jwtauthsvr/api/getUserInfoByName", request.getHeader("Authorization"));
//转成JsonObject JSONObject UserInfoReturn = JSON.parseObject(httpClientReturn);
//转成自定义Return报文对象 Return returnMsg = JSON.toJavaObject(UserInfoReturn, Return.class);
//获取报文里data参数 String JSONData = JSON.toJSONString(returnMsg.getData());
//转成UserInfo对象 UserInfo userInfo = JSON.parseObject(JSONData, UserInfo.class);
二：data里是个集合
{
"code": 200,
"message": "success",
"data": {
"total": 16,
"list": [
{
"userId": 1,
"userName": "Jamie",
"roles": "admin",
"realName": "测试人员",
"tel": "13651046002",
"email": "12345@qq.com",
"idCard": "1111111111",
"enabled": true,
"relType": 0,
"relId": 111098,
"password": "xxx",
"registrationTime": "2019-08-04 20:35:44",
"updateTime": "2019-08-04 20:35:44"
},
{
"userId": 2,
"userName": "Bruce",
"roles": "admin",
"realName": "测试人员2",
"tel": "13651046888",
"email": "wwee@qq.com",
"idCard": "370214199555555555",
"enabled": true,
"relType": 0,
"relId": 111099,
"password": "xxx",
"registrationTime": "2019-08-04 20:50:15",
"updateTime": "2019-08-04 20:50:15"
}
],
"pageNum": 1,
"pageSize": 25,
"size": 16,
"startRow": 1,
"endRow": 16,
"pages": 1,
"prePage": 0,
"nextPage": 0,
"isFirstPage": true,
"isLastPage": true,
"hasPreviousPage": false,
"hasNextPage": false,
"navigatePages": 8,
"navigatepageNums": [
1
],
"navigateFirstPage": 1,
"navigateLastPage": 1,
"firstPage": 1,
"lastPage": 1
}
}
1.解析httpclient返回的参数
//httpClient调用接口，返回String字符串
String httpClientReturn = HttpClientUtil.get("http://xxxxx:9099/jwtauthsvr/api/getUserInfoByName", request.getHeader("Authorization"));
//转成JsonObject
JSONObject UserInfoReturn = JSON.parseObject(httpClientReturn);
//获取返回报文格式
Return returnMsg = JSON.toJavaObject(UserInfoReturn, Return.class);
//获取报文里data参数
String JSONData = JSON.toJSONString(returnMsg.getData());
//获取data里的list
List<UserInfo> userInfoList = JSON.parseObject(JSONData, new TypeReference<List<UserInfo>>() {});
