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; } } |
2.编写自定义处理类,继承Converter接口

public class StringToGoodsConverter implements Converter<String, GoodsPromoteEnum> { @Override public GoodsPromoteEnum convert(String value) { if (StringUtils.isBlank(value)) { return null ; } return GoodsPromoteEnum.get(value); } } |
3.在springmvc配置文件里配置

<!--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 > |
