测试代码:
import org.apache.commons.jexl.*;
public class Demo
{
public static void main(String[] args) throws Exception
{
// Create an expression object
String jexlExp = “df.format(foo.getTime());”;
Expression e = ExpressionFactory.createExpression( jexlExp );
// Create a context and add data
JexlContext jc = JexlHelper.createContext();
java.text.SimpleDateFormat df=new java.text.SimpleDateFormat(“yyyy-MM-dd HH:mm:ss”);
jc.getVars().put(“df”, df);
jc.getVars().put(“foo”, new java.util.Date() );
// Now evaluate the expression, getting the result
String o = (String)e.evaluate(jc);
System.out.println(o);
}
}
