实现AMF3与Java之间数组的传递(动态创建数组)...
首先,AMF3似乎并不支持List.ArrayList等数组的解析...Java客户端传递List对象,AMF3无法解析为Array...
原因是:AMF3只支持基础数据类型...
故,需要将List等数据转换为Object[] !这样AMF3才能将Java传递的数组解析为Array...
由于数组的创建,即便一开始不赋值,也需要设置数组的length,如:String[] myString = new String[5];
故,需要动态创建Object[]数组.但往往,length一开始是并不知道,比如JDBC中ResultSet...
@SuppressWarnings("unchecked")
public Seed_Warehouse[] findSeedWarehouseByUserID(int userID)
throws SQLException {
String sql = "SELECT * from LESOGO_SEED_WAREHOUSE WHERE USER_ID = ?";
db.doPstm(sql, new Object[] { userID });
ResultSet rs = db.getRs();
if (rs != null) {
int i = 0; // 获得数据库表的行数!
while (rs.next()) {
i++;
}
Seed_Warehouse[] sws = new Seed_Warehouse[i];
rs.beforeFirst(); // 光标指向起始位置!
int j = 0;
while (rs.next()) {
Seed_Warehouse sw = new Seed_Warehouse();
sw.setId(rs.getInt(1));
sw.setCrop_class_name(rs.getString(2));
sw.setCrop_count(rs.getInt(3));
sw.setUser_id(rs.getInt(4));
sws[j++] = sw; // 为数据具体位置下的对象赋值!
}
return sws;
}
return null;
}
总结:
是要认真学习下AMF3协议了...

Closing a URLClassLoader
By Michael McMahon
Complex Java programs, such as application servers, sometimes create their own class loaders using the URLClassLoader type. With URLClassLoader, applications can load classes and resources from a search path of URLs. The following URL types are ......
