愿意接受关于如何使之更好的建议

这是我的胡子枚文件

  /**

   */
  @Getter
  @AllArgsConstructor
  public enum {{#datatypeWithEnum}}{{{.}}}{{/datatypeWithEnum}}{{^datatypeWithEnum}}{{classname}}{{/datatypeWithEnum}} {
    {{#gson}}
        {{#allowableValues}}
            {{#enumVars}}
    @SerializedName({{#isInteger}}"{{/isInteger}}{{#isDouble}}"{{/isDouble}}{{#isLong}}"{{/isLong}}{{#isFloat}}"{{/isFloat}}{{{value}}}{{#isInteger}}"{{/isInteger}}{{#isDouble}}"{{/isDouble}}{{#isLong}}"{{/isLong}}{{#isFloat}}"{{/isFloat}})
    {{{name}}}({{{value}}}){{^-last}},
    {{/-last}}{{#-last}};{{/-last}}

    {{/gson}}
    {{^gson}}
        {{#allowableValues}}
            {{#enumVars}}
    {{{name}}}({{{value}}}){{^-last}},
    {{/-last}}{{#-last}};{{/-last}}
            {{/enumVars}}
        {{/allowableValues}}
    {{/gson}}

    private {{{dataType}}} value;

    @Override
    public String toString() {
      return String.valueOf(value);
    }

    @JsonCreator
    public static {{#datatypeWithEnum}}{{{.}}}{{/datatypeWithEnum}}{{^datatypeWithEnum}}{{{classname}}}{{/datatypeWithEnum}} fromValue({{{dataType}}} value) {
      for ({{#datatypeWithEnum}}{{{.}}}{{/datatypeWithEnum}}{{^datatypeWithEnum}}{{{classname}}}{{/datatypeWithEnum}} b : {{#datatypeWithEnum}}{{{.}}}{{/datatypeWithEnum}}{{^datatypeWithEnum}}{{{classname}}}{{/datatypeWithEnum}}.values()) {
        if (b.value.equals(value)) {
          return b;
        }
      }
      {{#isNullable}}return null;{{/isNullable}}{{^isNullable}}throw new IllegalArgumentException("Unexpected value '" + value + "'");{{/isNullable}}
    }
  }

这里是enum外胡子类。

{{#jackson}}
import com.fasterxml.jackson.annotation.JsonCreator;
{{/jackson}}
import lombok.AllArgsConstructor;
import lombok.Getter;

/**

@Getter
@AllArgsConstructor
public enum {{#datatypeWithEnum}}{{{.}}}{{/datatypeWithEnum}}{{^datatypeWithEnum}}{{{classname}}}{{/datatypeWithEnum}} {
  {{#gson}}
      {{#allowableValues}}
          {{#enumVars}}
              @SerializedName({{#isInteger}}"{{/isInteger}}{{#isDouble}}"{{/isDouble}}{{#isLong}}"{{/isLong}}{{#isFloat}}"{{/isFloat}}{{{value}}}{{#isInteger}}"{{/isInteger}}{{#isDouble}}"{{/isDouble}}{{#isLong}}"{{/isLong}}{{#isFloat}}"{{/isFloat}})
              {{{name}}}({{{value}}}){{^-last}},
              {{/-last}}{{#-last}};{{/-last}}
          {{/enumVars}}
      {{/allowableValues}}
  {{/gson}}
  {{^gson}}
      {{#allowableValues}}
          {{#enumVars}}
              {{{name}}}({{{value}}}){{^-last}},
              {{/-last}}{{#-last}};{{/-last}}
          {{/enumVars}}
      {{/allowableValues}}
  {{/gson}}

  private {{{dataType}}} value;

  @JsonCreator
  public static {{#datatypeWithEnum}}{{{.}}}{{/datatypeWithEnum}}{{^datatypeWithEnum}}{{{classname}}}{{/datatypeWithEnum}} fromValue({{{dataType}}} value) {
    for ({{#datatypeWithEnum}}{{{.}}}{{/datatypeWithEnum}}{{^datatypeWithEnum}}{{{classname}}}{{/datatypeWithEnum}} b : {{#datatypeWithEnum}}{{{.}}}{{/datatypeWithEnum}}{{^datatypeWithEnum}}{{{classname}}}{{/datatypeWithEnum}}.values()) {
      if (b.value.equals(value)) {
        return b;
      }
    }
    {{#isNullable}}return null;{{/isNullable}}{{^isNullable}}throw new IllegalArgumentException("Unexpected value '" + value + "'");{{/isNullable}}
  }
}

下面是一个非常大的json文件的例子。

    "knowledgeLevelCode": {
        "type": "string",
        "enum": [
            "EXTENSIVE",
            "GOOD",
            "LIMITED",
            "NONE",
            "DECLINED"
        ],
        "description": "Knowledge Level Code."

这里是代码

  @Getter
  @AllArgsConstructor
  public enum KnowledgeLevelCodeEnum {
    EXTENSIVE("EXTENSIVE"),

    GOOD("GOOD"),

    LIMITED("LIMITED"),

    NONE("NONE"),

    DECLINED("DECLINED");

    private  value;

    @Override
    public String toString() {
      return String.valueOf(value);
    }

    @JsonCreator
    public static KnowledgeLevelCodeEnum fromValue( value) {
      for (KnowledgeLevelCodeEnum b : KnowledgeLevelCodeEnum.values()) {
        if (b.value.equals(value)) {
          return b;
        }
      }
      throw new IllegalArgumentException("Unexpected value '" + value + "'");
    }
  }

不知道是什么原因导致错过了数据类型。

有趣的是，如果我使用OpenApi，数据类型就会被放入，但是嵌套的includes有一个问题，导致它把几个实际类型变成了普通的对象。

好吧，经过大量的搜索，我找到了答案。 基本上是数据类型的大小写敏感性问题。 他们在某个地方把数据类型改成了dataType，但我用来生成的版本需要它是小写的t，所以改成这样就可以了。

{{#jackson}}
import com.fasterxml.jackson.annotation.JsonCreator;
{{/jackson}}
import lombok.AllArgsConstructor;
import lombok.Getter;

/**
 * {{^description}}Gets or Sets {{{name}}}{{/description}}{{#description}}{{{description}}}{{/description}}
 */
@Getter
@AllArgsConstructor
public enum {{#datatypeWithEnum}}{{{.}}}{{/datatypeWithEnum}}{{^datatypeWithEnum}}{{{classname}}}{{/datatypeWithEnum}} {
  {{#gson}}
      {{#allowableValues}}
          {{#enumVars}}
              @SerializedName({{#isInteger}}"{{/isInteger}}{{#isDouble}}"{{/isDouble}}{{#isLong}}"{{/isLong}}{{#isFloat}}"{{/isFloat}}{{{value}}}{{#isInteger}}"{{/isInteger}}{{#isDouble}}"{{/isDouble}}{{#isLong}}"{{/isLong}}{{#isFloat}}"{{/isFloat}})
              {{{name}}}({{{value}}}){{^-last}},
              {{/-last}}{{#-last}};{{/-last}}
          {{/enumVars}}
      {{/allowableValues}}
  {{/gson}}
  {{^gson}}
      {{#allowableValues}}
          {{#enumVars}}
              {{{name}}}({{{value}}}){{^-last}},
              {{/-last}}{{#-last}};{{/-last}}
          {{/enumVars}}
      {{/allowableValues}}
  {{/gson}}

  private {{{datatype}}} value;

  @JsonCreator
  public static {{#datatypeWithEnum}}{{{.}}}{{/datatypeWithEnum}}{{^datatypeWithEnum}}{{{classname}}}{{/datatypeWithEnum}} fromValue({{{datatype}}} value) {
    for ({{#datatypeWithEnum}}{{{.}}}{{/datatypeWithEnum}}{{^datatypeWithEnum}}{{{classname}}}{{/datatypeWithEnum}} b : {{#datatypeWithEnum}}{{{.}}}{{/datatypeWithEnum}}{{^datatypeWithEnum}}{{{classname}}}{{/datatypeWithEnum}}.values()) {
      if (b.value.equals(value)) {
        return b;
      }
    }
    {{#isNullable}}return null;{{/isNullable}}{{^isNullable}}throw new IllegalArgumentException("Unexpected value '" + value + "'");{{/isNullable}}
  }
}
