可以使用 JSON 解析库，如 Jackson 或者 Gson，将 JSON 字符串解析成 Java 对象，然后通过对象的相应字段获取到 personPhoto 字段。假设使用 Jackson 库，代码如下：

import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;

String jsonStr = "{ \"code\": \"0\", \"msg\": \"success\", \"data\": { \"total\": 1, \"list\": [ { \"personId\": \"3377634\", \"personName\": \"杨博\", \"gender\": 1, \"orgIndexCode\": \"13211331\", \"certificateType\": 111, \"certificateNo\": \"642223199811280016\", \"jobNo\": \"90223505\", \"birthday\": \"1998-11-28\", \"phoneNo\": \"18309540994\", \"email\": \"\", \"pinyin\": \"yangbo\", \"createTime\": \"2022-09-16T02:03:01.622+08:00\", \"updateTime\": \"2022-11-14T19:10:59.071+08:00\", \"faceNum\": 1, \"fingerprintNum\": 0, \"orgName\": \"宁夏宝丰能源集团股份有限公司信息化部\", \"orgPath\": \"@root000000@a1d7bcc3-7e73-4aa5-be78-e7448aed6111@13201129@13211280@13211331@\", \"orgPathName\": \"宝丰集团/员工同步组织/宁夏宝丰集团/宁夏宝丰能源集团股份有限公司/宁夏宝丰能源集团股份有限公司信息化部\", \"orgList\": [ \"13211331\" ], \"personPhoto\": [ { \"serverIndexCode\": \"b0c6e000-091c-4144-a95d-cbea801812d2\", \"personPhotoIndexCode\": \"0f5fb936-3172-4a11-82ec-51356ff0be30\", \"picUri\": \"/pic?0df926994e9do-bel*41-e05*8o0=6=4705*9l5944279166*7t==312**ps8=1b3=07c2*135e71327-a5308d-2pi1e4o=00c50=805\" } ] } ] } }";
ObjectMapper objectMapper = new ObjectMapper();
JsonNode jsonNode = objectMapper.readTree(jsonStr);
JsonNode personPhoto = jsonNode.at("/data/list/0/personPhoto");
System.out.println(personPhoto);

其中，`jsonStr` 是待解析的 JSON 字符串，`JsonNode` 是 Jackson 库中的 JSON 对象，`objectMapper` 是 Jackson 的解析器，`at` 方法是用来获取指定 JSON 节点的方法。运行上面的代码，会输出 `personPhoto` 字段的值，即：

[ {
  "serverIndexCode" : "b0c6e000-091c-4144-a95d-cbea801812d2",
  "personPhotoIndexCode" : "0f5fb936-3172-4a11-82ec-51356ff0be30",
  "picUri" : "/pic?0df926994e9do-bel*41-e05*8o0=6=4705*9l5944279166*7t==312**ps8=1b3=07c2*135e71327-a5308d-2pi1e4o=00c50=805"
} ]
