Question

我的hbm文件条目

        <property name="rideType">
            <column name="rideType" />
            <type name="org.hibernate.type.EnumType">
                <param name="enumClass">com.mcruiseon.common.Globals.RideType</param>
                <param name="type">12</param>               
            </type>
        </property>

异常

代码

public class Globals {
     ...whole bunch of code...
     public enum RideType {
        PER_KM("PER_KM"), PER_HOUR_1("PER_HOUR_1"), PER_HOUR_2("PER_HOUR_2"), PER_HOUR_4(
                "PER_HOUR_4"), PER_HOUR_8("PER_HOUR_8"), PER_HOUR_10(
                "PER_HOUR_10"), PER_HOUR_12("PER_HOUR_12"), PER_HOUR_16(
                "PER_HOUR_16");
        private String description;

        RideType(String description) {
            this.description = description;
        }

        public String getDescription() {
            return new String(description);
        }

        public static RideType getRideType(String value) {
            if ("PER_KM".equalsIgnoreCase(value))
                return PER_KM;
            else if ("PER_HOUR_1".equalsIgnoreCase(value))
                return PER_HOUR_1;
            else if ("PER_HOUR_2".equalsIgnoreCase(value))
                return PER_HOUR_2;
            else if ("PER_HOUR_4".equalsIgnoreCase(value))
                return PER_HOUR_4;
            else if ("PER_HOUR_8".equalsIgnoreCase(value))
                return PER_HOUR_8;
            else if ("PER_HOUR_10".equalsIgnoreCase(value))
                return PER_HOUR_10;
            else if ("PER_HOUR_12".equalsIgnoreCase(value))
                return PER_HOUR_12;
            else if ("PER_HOUR_16".equalsIgnoreCase(value))
                return PER_HOUR_16;
            return null;
        }
    };
    ...whole bunch of code...
}

我已经尝试了所有的SO问题和答案，并且由于一些疯狂的原因它仍然抛出这个例外。我在这里缺少什么？

Answer 1

这看起来像是在类（内部类枚举）中声明的枚举。如果这是真的。

更改：

<param name="enumClass">com.mcruiseon.common.Globals.RideType</param>

要：

<param name="enumClass">com.mcruiseon.common.Globals$RideType</param>

引起：java.lang.ClassNotFoundException：com.mcruiseon.common.Globals.RideType
