list<?>转换成 对应的 class

项目中用到的，list转换成bean。因为查询出来的数据用list 泛型接收，要返回 实体对象。所以需要对应转换。

主要用到的技术：反射。

上代码：

public static <T> List<T> toBean(List<?> list, Class<T> clz) {
        int count = 0;
        Field[] fields = clz.getDeclaredFields();
        List<T> lst = new ArrayList();
        String propertyName = "";
        Object obj = null;
 
        try {
            for(int i = 0; i < list.size(); ++i) {
                obj = clz.newInstance();
                Object[] oo = (Object[])list.get(i);
                Field[] var12 = fields;
                int var11 = fields.length;
 
                for(int var10 = 0; var10 < var11; ++var10) {
                    Field fd = var12[var10];
                    Type t = fd.getGenericType();
                    String className = t.toString().replace("class", "");
                    Class<?> type = Class.forName(className.trim());
                    propertyName = "set" + change(fd.getName());
                    Method mt = obj.getClass().getMethod(propertyName, new Class[]{type});
                    if(!"java.lang.String".equals(className.trim())) {
                        if("java.lang.Integer".equals(className.trim())) {
                            mt.invoke(obj, new Object[]{Integer.valueOf(Integer.parseInt(oo[count] == null?"-1":oo[count].toString()))});
                        } else if("java.lang.Long".equals(className.trim())) {
                            mt.invoke(obj, new Object[]{Long.valueOf(Long.parseLong(oo[count] == null?"-1":oo[count].toString()))});
                        } else {
                            Clob clobs;
                            if("java.sql.Date".equals(className.trim())) {
                                Date date = (Date)oo[count];
                                if(!"".equals(date) && date != null) {
                                    java.sql.Date sd = new java.sql.Date(date.getTime());
                                    mt.invoke(obj, new Object[]{sd});
