先定义数据类型

package com.whereta.common;/** * Created by vincent on 15-9-24. */public enum JavaBasicTypeEnum {    STRING(String.class),    INTEGER(Integer.class),    BOOLEAN(Boolean.class),    BYTE(Byte.class),    LONG(Long.class),    SHORT(Short.class),    FLOAT(Float.class),    DOUBLE(Double.class),    CHAR(Character.class);    private Class sClass;    JavaBasicTypeEnum(Class sClass) {        this.sClass = sClass;    }    protected static boolean isBasicType(Class sClass) {        for (JavaBasicTypeEnum en : JavaBasicTypeEnum.values()) {            Class aClass = en.getsClass();            if (aClass.equals(sClass)) {                return true;            }        }        return false;    }    public Class getsClass() {        return sClass;    }    public void setsClass(Class sClass) {        this.sClass = sClass;    }}

数据类型判断
