java无法从YAML文件中删除特定的key:value
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
值不会删除
错误消息:没有错误消息
我尝试的内容:我有一个招摇过市的YAML文件,我只是将其加载到Jackson ObjectMapper中,并尝试从该YAML文件中删除一些键。然后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originalRef
属性中删除responses
键及其值
下面是我的YamlProcessor。java类,它完成所有必要的事情
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。还将生成新的YAML文件。 但是在新的YAML文件中,responses属性下仍然有originlaRef key contains。 谁来告诉我我做错了什么。 任何帮助都将不胜感激。 干杯你好
