属性加public 修饰可解决。
例:
public static class Apple {
int price;
}
public void test2() {
ObjectMapper objectMapper = new ObjectMapper();
String jsonApple = "{\"price\":100}";
Apple apple = new Apple();
try {
apple = objectMapper.readValue(jsonApple, Apple.class);
System.out.println("apple price:" + apple.price);
} catch (IOException e) {
e.printStackTrace();
}
}
com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "price"
price 属性加public 修饰可解决:
public static class Apple {
public int price;
}
