通过java反射实现对javabean生成各种sql语句，有请大家评论，更改
Java代码:
package com.pdt.util;
import java.lang.reflect.Field;
import java.util.ArrayList;
import java.util.List;
public class BeanUtil {
/** 原文地址：http://www.software8.co/wzjs/java/2875.html
* @param args
*/
public static void main(String[] args) {
System.out.println(getBeanFilesList("com.pdt.bean.Dictionary"));
System.out.println(genCreateTableSql("com.pdt.bean.Dictionary"));
System.out.println(genInsertSql("com.pdt.bean.Dictionary"));
}
public static String getBeanName(String bean){
try {
Class clz = Class.forName(bean);
String clzStr = clz.toString();
//得到类名
String beanName = clzStr.substring(clzStr.lastIndexOf(".")+1).toLowerCase();
return beanName;
} catch (ClassNotFoundException e) {
e.printStackTrace();
return "";
}
}
public static List<String> getBeanPropertyList(String bean){
try {
Class clz = Class.forName(bean);
Field[] strs = clz.getDeclaredFields();
List<String> propertyList = new ArrayList<String>();
for (int i = 0; i < strs.length; i++) {
String protype = strs[i].getType().toString();
propertyList.add(protype.substring(protype.lastIndexOf(".")+1)+"`"+strs[i].getName());
}
return propertyList;
} catch (ClassNotFoundException e) {
e.printStackTrace();
return null;
}
}
public static String getBeanFilesList(String bean){
try {
Class clz = Class.forName(bean);
Field[] strs = clz.getDeclaredFields();
StringBuffer sb = new StringBuffer();
for (int i = 0; i < strs.length; i++) {

if (!strs[i].getName().equals("tableName")&&!strs[i].getType().equals("List")) {
sb.append(strs[i].getName()+",");
}
}
sb.deleteCharAt(sb.toString().lastIndexOf(","));
return sb.toString();
} catch (ClassNotFoundException e) {
e.printStackTrace();
return null;
}
}
/**

* @param bean

*/
public static String genCreateTableSql(String bean){
List<String> beanPropertyList = getBeanPropertyList(bean);

}
