springmvc默认无法自动封装枚举类，解决方法如下：
1.枚举类
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;
}
}
</div>
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);
}
}
</div>
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>
</div>
