Summer rolls are made of fresh vegetables, rolled in a rice paper wrapper. They sometimes include pork, shrimp, or shredded chicken. They are generally not fried and are typically served with a peanut dipping sauce. Spring rolls, on the other hand, are typically vegetarian, though they can sometimes include pork. They're also generally wrapped in a crunchy spring roll wrapper and deep fried, served with a sweet chili or hoisin dipping sauce.
