ObjectMapper String轉集合

` public static final ObjectMapper objectMapper = new ObjectMapper();

public static JavaType getCollectionType(Class<?> collectionClass, Class<?>... elementClasses) {
    return objectMapper.getTypeFactory().constructParametricType(collectionClass, elementClasses);
}

JavaType javaType = getCollectionType(Map.class, String.class, Object.class);
            Map<String, Object> data = objectMapper.readValue(strData, javaType);`
