Jackson用spring接口列表反序列化对象

我认为您需要添加自定义解串器

public class UserAccountAuthenticationSerializer extends JsonDeserializer<UserAccountAuthentication> {@Overridepublic UserAccountAuthentication deserialize(JsonParser jsonParser, DeserializationContext deserializationContext)        throws IOException {    UserAccountAuthentication userAccountAuthentication = new UserAccountAuthentication();    ObjectCodec oc = jsonParser.getCodec();    JsonNode node = oc.readTree(jsonParser);    userAccountAuthentication.setAuthenticated(node.get("authenticated").booleanValue());    Iterator<JsonNode> elements = node.get("authorities").elements();    while (elements.hasNext()) {        JsonNode next = elements.next();        JsonNode authority = next.get("authority");        userAccountAuthentication.getAuthorities().add(new SimpleGrantedAuthority(authority.asText()));    }    return userAccountAuthentication;}

}

这是我的json

{"authenticated":true,"authorities":[{"authority":"role1"},{"authority":"role2"}],"details":null,"principal":null,"credentials":null,"name":null}

然后在您的POJO顶部

@JsonDeserialize(using = UserAccountAuthenticationSerializer.class)public class UserAccountAuthentication  implements Authentication {

这是测试

@Testpublic void test1() throws IOException {UserAccountAuthentication userAccountAuthentication = new UserAccountAuthentication();userAccountAuthentication.setAuthenticated(true);userAccountAuthentication.getAuthorities().add(new SimpleGrantedAuthority("role1"));userAccountAuthentication.getAuthorities().add(new SimpleGrantedAuthority("role2"));String json1 = new ObjectMapper().writevalueAsString(userAccountAuthentication);UserAccountAuthentication readValue = new ObjectMapper().readValue(json1, UserAccountAuthentication.class);String json2 = new ObjectMapper().writevalueAsString(readValue);assertEquals(json1, json2);

}
