无法删除特定键：YAML 文件中的值

Question

目标：我想从 YAML 文件中删除特定键及其关联值。

预期结果：orginalRef 键及其值应从 YAML 文件中删除，并应生成新的 YAML 文件。

实际结果：responses 属性下的orginalRef 值不会被删除。

错误消息：没有错误消息。

我尝试过什么：我有一个大摇大摆的 YAML 文件，我只是将它加载到 Jackson ObjectMapper 并尝试从该 YAML 文件中删除一些键。然后使用我所做的更改生成一个新的 YAML 文件。

代码： 下面是我巨大的 YAML 文件的一部分。它的名字是api.yaml

如您所见，我只想从上述 YAML 文件中的 responses 属性中删除 originalRef 键和它的值。

下面是我的 YamlProcessor.java 类，它完成了所有必要的事情。

package com.aos.tools.aostool.yaml;

import com.fasterxml.jackson.core.type.TypeReference;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.dataformat.yaml.YAMLFactory;
import org.springframework.stereotype.Service;

import java.io.File;
import java.io.IOException;
import java.util.*;
import java.util.stream.Stream;

@Service
public class YamlProcessor {

    public YamlProcessor() throws IOException {
        process();
    }

    public void process() throws IOException {
        final ObjectMapper objectMapper = new ObjectMapper(new YAMLFactory());

        final Map<String, Object> api = objectMapper.readValue(new File("api.yaml"),
                new TypeReference<Map<String, Object>>() {
                });

        final Map<String, Object> path = (Map<String, Object>) api.get("paths");
        processPath(path);

        // write YAML file
        final Date date = Calendar.getInstance().getTime();
        objectMapper.writeValue(new File(date.toString() + "api-updated.yaml"), api);
    }

    private void processPath(final Map<String, Object> paths) {
        paths.entrySet().forEach(path -> {
            if (null != path) {
                final Map<String, Object> level1Child = (Map<String, Object>) path.getValue();
                if (null != level1Child) {
                    level1Child.entrySet().forEach(method -> {
                        final Map<String, Object> methodValues = (Map<String, Object>) method.getValue();
                        methodValues.entrySet().forEach(methodValue -> {
                            if (null != methodValue && methodValue.getKey().equals("parameters")) {
                                final List<Object> paramValue = (List<Object>) methodValue.getValue();
                                paramValue.forEach(paramValueChild -> {
                                    if (null != paramValueChild) {
                                        final Map<String, Object> paramMap = (HashMap<String, Object>) paramValueChild;
                                        paramMap.entrySet().forEach(k -> {
                                            if (k.getKey().contains("schema")) {
                                                final Map<String, Object> schema = (HashMap<String, Object>) k.getValue();
                                                // this line works fine , this will remove all the originalRef keys under parameters property
                                                schema.remove("originalRef"); 
                                            }
                                        });
                                    }
                                });
                            }

                            // this is where I'm currently getting stucked.
                            if (null != methodValue && methodValue.getKey().equals("responses")) {
                                Map<String,Object> value = (HashMap<String,Object>) methodValue.getValue();
                                if(value.containsKey("200")) {
                                    value.entrySet().forEach(k -> {
                                        if(k.getKey().contains("schema")) {
                                            Map<String,Object> responseSchema = (HashMap<String,Object>)k.getValue();
                                            responseSchema.remove("originalRef");
                                        }
                                    });
                                }
                            }
                        });
                    });
                }
            }
        });
    }
}

当我运行应用程序时，它运行良好，没有任何错误。同时生成新的 YAML 文件。 但在新的 YAML 文件中，responses 属性下仍然包含 originlaRef 键。 任何人都在这里指导我做错了什么。 任何帮助将不胜感激。 干杯!美好的一天！

Answer 1

您正在迭代 value 的内容，而不是 value.200

 if(value.containsKey("200")) {
          value.entrySet().forEach(k -> {

应该是

 if(value.containsKey("200")) {
          value.get("200").entrySet().forEach(k -> {

在任何情况下，您都可以将日志语句放入循环中以调试此类事情。

Answer 2

我终于可以通过我的代码进行实验来获得所需的输出。

下面是我的工作解决方案。

if(value.containsKey("200")) {
    value.entrySet().forEach(k -> {
        Map<String,Object> responseSchema = (HashMap<String,Object>) k.getValue();
        responseSchema.entrySet().forEach(a -> {
            if(a.getKey().contains("schema")) {
                Map<String,Object> reSchema = (HashMap<String,Object>)a.getValue();
                reSchema.entrySet().forEach(c -> {
                    if(c.getKey().contains("items")) {
                        Map<String,Object> innerSchema = (HashMap<String,Object>) c.getValue();
                        innerSchema.remove("originalRef");
                    }
                });
            }
        });
    });
}
