Now that LoaderOptions provide the setAllowDuplicateKeys option, we don't need the StrictMapAppenderConstructor anymore?

Suggested change

	StrictMapAppenderConstructor constructor = new StrictMapAppenderConstructor();
	Representer representer = new Representer();
	DumperOptions dumperOptions = new DumperOptions();
	dumperOptions.setDefaultFlowStyle(representer.getDefaultFlowStyle());
	dumperOptions.setDefaultScalarStyle(representer.getDefaultScalarStyle());
	dumperOptions.setAllowReadOnlyProperties(representer.getPropertyUtils().isAllowReadOnlyProperties());
	dumperOptions.setTimeZone(representer.getTimeZone());
	LoaderOptions loadingConfig = new LoaderOptions();
	loadingConfig.setAllowDuplicateKeys(false);
	return new Yaml(constructor, representer, dumperOptions, loadingConfig);
	LoaderOptions loadingConfig = new LoaderOptions();
	loadingConfig.setAllowDuplicateKeys(false);
	return new Yaml(new SafeConstructor(), new Representer(), new DumperOptions(), loadingConfig);

BTW, why would we need to set the configs of DumperOptions?

[shoothzj]

@nobodyiam I test the setAllowDuplicateKeys, it doesn't work. SnakeYaml library will use LoaderOptions to override the Consurtor option. If you don't pass the LoaderOptions, the default value is true. I am not sure if it's a bug or a feature.

public Yaml(BaseConstructor constructor, Representer representer) {
        this(constructor, representer, initDumperOptions(representer));
    }

    private static DumperOptions initDumperOptions(Representer representer) {
        DumperOptions dumperOptions = new DumperOptions();
        dumperOptions.setDefaultFlowStyle(representer.getDefaultFlowStyle());
        dumperOptions.setDefaultScalarStyle(representer.getDefaultScalarStyle());
        dumperOptions.setAllowReadOnlyProperties(representer.getPropertyUtils().isAllowReadOnlyProperties());
        dumperOptions.setTimeZone(representer.getTimeZone());
        return dumperOptions;
    }

    /**
     * Create Yaml instance. It is safe to create a few instances and use them
     * in different Threads.
     *
     * @param representer   Representer to emit outgoing objects
     * @param dumperOptions DumperOptions to configure outgoing objects
     */
    public Yaml(Representer representer, DumperOptions dumperOptions) {
        this(new Constructor(), representer, dumperOptions, new LoaderOptions(), new Resolver());
    }

For DumperOptions, I copy the code in YamlParser for compatibility.

Summarize, we can't config AllowDuplicateKeys through constructor param

[shoothzj]

@nobodyiam And If we remove the StrictMapAppenderConstructor, the testcase9 in com.ctrip.framework.apollo.util.yaml.YamlParserTest can't paas

[nobodyiam]

@shoothzj

To make testcase9 work, I think we need to use SafeConstructor instead of Constructor.
BTW, I also tried the setAllowDuplicateKeys option as below and testcase2 which tests the duplicate key scenario works as expected. Is there any difference in your test case setup?

  private Yaml createYaml() {
    LoaderOptions loadingConfig = new LoaderOptions();
    loadingConfig.setAllowDuplicateKeys(false);
    return new Yaml(new SafeConstructor(), new Representer(), new DumperOptions(), loadingConfig);
  }

[shoothzj]

@nobodyiam I have misunderstood your meaning. I thought you want to remove the constructor, only keep the LoadOptions.
Please take a look again @nobodyiam
