详解SpringMVC 自动封装枚举类的方法

public enum GoodsPromoteEnum {  /**   * 0 精品   */  fine("精品",0),  /**   * 1 限时购   */  limit("限时购",1),   /**   * 2 特价   */  cheap("特价",2);    private String value;  private int index;  private GoodsPromoteEnum(String value, int index) {    this.value = value;    this.index = index;  }    public static GoodsPromoteEnum get(String value){    for (GoodsPromoteEnum p : GoodsPromoteEnum.values()) {      if (p.getValue().equals(value)) {        return p;      }    }    return null;  }    public static GoodsPromoteEnum get(int index){    for (GoodsPromoteEnum p : GoodsPromoteEnum.values()) {      if (p.getIndex() == index) {        return p;      }    }    return null;  }  public String getValue() {    return value;  }  public void setValue(String value) {    this.value = value;  }  public int getIndex() {    return index;  }  public void setIndex(int index) {    this.index = index;  }}

public class StringToGoodsConverter implements Converter<String, GoodsPromoteEnum> {  @Override  public GoodsPromoteEnum convert(String value) {    if (StringUtils.isBlank(value)) {     return null;    }    return GoodsPromoteEnum.get(value);  }}

  <!--自定义枚举类封装 -->  <bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">    <property name="converters">     <set>      <bean class="com.tentcoo.zbh.util.StringToGoodsConverter" />     </set>    </property>   </bean>
