public enum GoodsPromoteEnum { /** * 0 精品 */ fine("精品",0), /** * 1 限時購 */ limit("限時購",1), /** * 2 特價 */ cheap("特價",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.編寫自定義處理類，繼承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

<!--自定義枚舉類封裝 --><bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean"> <property name="converters"> <set> <bean class="com.tentcoo.zbh.util.StringToGoodsConverter" /> </set> </property> </bean> |
