直接.fieldName += 就会报错

已成功解决,在朋友的帮忙下,试出来的!
一下加粗字段,不要进行gson的转换操作,查阅源码 脚本的参数Map<String,? extends Object>,可将Map直接使用@test
public void testRestClient() throws IOException {
RestClient restClient = RestClient.builder(new HttpHost("10.12.31.110", 9200, "http")).build();

Map<String, String> param = new HashMap<>();
String script = "def f = ctx._source.student; f.books.findAll{ f.books +=listValue}";

Map<String, String> params = new HashMap<>();
Map<String, String> objectParam = new HashMap<>();
objectParam.put("name", "http");
objectParam.put("id", "15");
List<Map<String, String>> listParam = new ArrayList<>();
listParam.add(objectParam);

//params.put("listValue", GSON.toJson(listParam));
//params.put("objectValue", GSON.toJson(objectParam));

 
params.put("listValue", objectParam);
params.put("objectValue", listParam);


param.put("listValue", GSON.toJson(listParam));
param.put("objectValue", GSON.toJson(objectParam));

param.put("params", GSON.toJson(params));

StringBuilder dBuilder = new StringBuilder();
dBuilder.append("%20-d%20'").append(GSON.toJson(param)).append("'");

final Script groovyScript = new Script(script, ScriptService.ScriptType.INLINE, "groovy", params);
HttpEntity entity = new StringEntity(GSON.toJson(groovyScript), ContentType.APPLICATION_JSON);

final Response post = restClient.performRequest("POST", "/test_ool/ool/1/_update" /*+ dBuilder.toString()*/,
Collections.emptyMap(), entity);

System.out.println(post);
}
