hibernate 自定义枚举类型映射

自定义类型MyEnumType

定义枚举类型

package com.binarysource.hibernate.enumeration;public enum SexType {Male("0","男"),Female("1","女");private String type;private String name;public static String getNameByType(String type){SexType[] modes = SexType.values();for (SexType mode : modes) {if(mode.type.equals(type)){return mode.name;}}return null;}public static SexType getSexTypeByName(String name){SexType[] modes = SexType.values();for (SexType mode : modes) {if(mode.name.equals(name)){return mode;}}return null;}private SexType(String type,String name){this.type = type;this.name = name;}public String getType() {return type;}public void setType(String type) {this.type = type;}public String getName() {return name;}public void setName(String name) {this.name = name;}}

entity中使用枚举

   private SexType sexType;    @Type(type="com.binarysource.hibernate.MyEnumType",parameters={@Parameter(name="enumClass",value="com.binarysource.hibernate.SexType")})    public SexType getSexType() {        return sexType;    }    public void setSexType(SexType sexType) {        this.sexType = sexType;    }
