String转json，多层json解析，并使用JsonElement对比两个json对象的值是否相等

标签：one   数组类   test   需要   dep   导入   artifact   str   stat   

导入需要的jar包：

<dependency>
    <groupId>com.google.code.gson</groupId>
    <artifactId>gson</artifactId>
    <version>2.8.2</version>
</dependency>

示例：

public class JsonTest {


    public static void main(String[] args) {
        String rightAnswer = "{\"unit\":\"单位\",\"year\":\"2018\",\"form\":[{\"subject\":\"数学\",\"summary\":[11,12,13],\"score\":\"88.00\"},{\"subject\":\"语文\",\"summary\":[13,11],\"score\":\"99.00\"},{\"subject\":\"化学\",\"summary\":[],\"score\":\"77.00\"},{\"subject\":\"政治\",\"summary\":[1],\"score\":\"100.00\"}],\"people\":\"花花\"}";
        String answer = "{\"unit\":\"单位\",\"year\":\"2018\",\"form\":[{\"subject\":\"数学\",\"summary\":[11,12,13],\"score\":\"88.00\"},{\"subject\":\"语文\",\"summary\":[13,11],\"score\":\"99.00\"},{\"subject\":\"化学\",\"summary\":[],\"score\":\"77.00\"},{\"subject\":\"政治\",\"summary\":[1],\"score\":\"100.00\"}],\"people\":\"草草\"}";

        String a = "{\"error\":[10,14],\"imgId\":[1]}";
        String b = "{\"error\":[14,10],\"imgId\":[]}";
        
        JsonParser jsonParser = new JsonParser();
        System.out.println("=====" + JsonTest.test(jsonParser.parse(answer), jsonParser.parse(rightAnswer)));
    }

            if (rightAnswerJsonArray.size() == answerElement.getAsJsonArray().size()) {
            //数组类型顺序会影响取值，所以每个数组都要全部匹配验证另外一个对象的数组。
            //例如：[10,14]和[14,10]
                for (int i = 0; i < rightAnswerJsonArray.size(); i ++) {
                    boolean flag = false;
                    JsonArray answerJsonArray = answerElement.getAsJsonArray();
                    for (int j = 0; j < answerJsonArray.size(); j ++) {
                        if (JsonTest.test(answerElement.getAsJsonArray().get(j), rightAnswerJsonArray.get(i))) {

                            break;
                        }
                    }
                    if (!flag) {
                        return false;
                    }
                }
            } else {
                return false;
            }
        } else if (rightAnswerElement.isJsonObject()) {

                    return false;
                }
            }
        } else if (rightAnswerElement.isJsonPrimitive()) {
            String rightAnswer = rightAnswerElement.getAsString();
            String answer = answerElement.getAsString();
            System.out.println("rightAnswer = " + rightAnswer + ", answer = " + answer);
            if (!rightAnswer.equals(answer)) {
                return false;
