1.将对象转换为JSON字符串,返回值为一个JSON字符串
public static String toJson(Object value) {
try {
return mapper.writevalueAsString(value);
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
2. 将JSON字符串转换为实体对象,返回值为实体对象
public staticT toObject(String json, Class valueType) { Assert.hasText(json); Assert.notNull(valueType); try { SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); mapper.setDateFormat(dateFormat); return mapper.readValue(json, valueType); } catch (Exception e) { e.printStackTrace(); } return null;
