OrientDB 3.0.4 Java OValidationException：该字段已声明为EMBEDDEDLIST，但使用了不兼容的类型

时间：2018-07-12 18:43:42

标签： java orientdb embeddedlist

我正在使用OrientDB版本3.0.4 Java和orientdb-client.3.0.4 Java驱动程序/库。

我正尝试使用EMBEDDEDLIST类型，如下所示：

数据库架构：

create class Phone EXTENDS V

create property Phone.number String

create class Profile EXTENDS V

create property Profile.name String

create property Profile.phone embeddedList Phone

使用OrientDB控制台，可以进行以下工作：

CREATE VERTEX Profile SET name = "User1", phone = [{ "number" : "914" }, { "number" : "212" }]


     SELECT * From Profile where name="User1"               

+----+------+-------+-----+-------------------------------------+
|#   |@RID  |@CLASS |name |phone                                |
+----+------+-------+-----+-------------------------------------+
|0   |#198:2|Profile|User1|[Phone{number:914},Phone{number:212}]|
+----+------+-------+-----+-------------------------------------+

使用Java失败：

尝试创建具有两个作为列表（ArrayList）存储的Phone对象的Profile Vertex时，代码失败，但出现以下异常：

com.orientechnologies.orient.core.exception.OValidationException: The field 'Profile.phone' has been declared as EMBEDDEDLIST but an incompatible type is used. Value: Phone{number:212}
    DB name="test"
    Error Code="4"
    at com.orientechnologies.orient.core.record.impl.ODocument.validateEmbedded(ODocument.java:814)

代码如下：

    public void insertProfileTest() throws JsonProcessingException {
        LOGGER.info(dbSession.getMetadata().getSchema().getClass(Profile.class).getProperty("name").toString());
        LOGGER.info(dbSession.getMetadata().getSchema().getClass(Profile.class).getProperty("phone").toString());
        LOGGER.info(dbSession.getMetadata().getSchema().getClass(Phone.class).getProperty("number").toString());

        // Init
        Profile userProfile = new Profile("Jane Doe");
        Phone homePhone = new Phone("212");
        Phone cellPhone = new Phone("718");
        userProfile.addPhone(homePhone);
        userProfile.addPhone(cellPhone);
        final String json = MAPPER.writeValueAsString(userProfile);
        LOGGER.info("Profile JSON:" + json);
        LOGGER.info("Phone Class :" + userProfile.getPhone().getClass().getName());

        // DB
        final OVertex profileVertex = dbSession.newVertex("Profile");
        profileVertex.setProperty("name", userProfile.getName());
        profileVertex.setProperty("phone", userProfile.getPhone(), OType.EMBEDDEDLIST);

        // Fails to Save -
        // The field 'Profile.phone' has been declared as EMBEDDEDLIST but an incompatible type is used. Value: com.sample.profile.Phone@32f232a5
        profileVertex.save();
    }

以下是输出：

以下是Java类：


    package com.sample.profile;

    public class Phone  {
        private String number;

        public Phone() {
        }

        public Phone(String number) {
            this.number = number;
        }

        public String getNumber() {
            return number;
        }

        public void setNumber(String number) {
            this.number = number;
        }

        @Override
        public String toString() {
            return "Phone{" +
                    "number:" + number +
                    '}';

        }
    }


    package com.sample.profile;

    import java.util.ArrayList;
    import java.util.Arrays;
    import java.util.Collection;

    public class Profile {

        private String name;
        private Collection phone;

        public Profile() {
        }

        public Profile(String name) {
            this.name = name;
        }

        public Profile(String name, Collection phone) {
            this.name = name;
            this.phone = phone;
        }

        public void addPhone(Phone phoneNumber)
        {
            if (this.phone == null) {
                this.phone = new ArrayList();
            }
            this.phone.add(phoneNumber);
        }
        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

        public Collection getPhone() {
            return phone;
        }

        public void setPhone(Collection phone) {
            this.phone = phone;
        }

        @Override
        public String toString() {
            return "Profile{" +
                    "name='" + name + '\'' +
                    ", phone=" + Arrays.toString(phone.toArray()) +
                    '}';
        }
    }

解决方案：

我解决了以下问题：

    public void insertProfileTest() throws JsonProcessingException {
        LOGGER.info(dbSession.getMetadata().getSchema().getClass(Profile.class).getProperty("name").toString());
        LOGGER.info(dbSession.getMetadata().getSchema().getClass(Profile.class).getProperty("phone").toString());
        LOGGER.info(dbSession.getMetadata().getSchema().getClass(Phone.class).getProperty("number").toString());

        // Init
        Profile userProfile = new Profile("Jane Doe");
        Phone homePhone = new Phone("212");
        Phone cellPhone = new Phone("718");
        userProfile.addPhone(homePhone);
        userProfile.addPhone(cellPhone);
        final String json = MAPPER.writeValueAsString(userProfile);
        LOGGER.info("Profile JSON:" + json);
        LOGGER.info("Phone Class :" + userProfile.getPhone().getClass().getName());

        // DB
        List phoneVertexList = new ArrayList();
        for (Phone phone: userProfile.getPhone()) {
            final OVertex phoneVertex = dbSession.newVertex("Phone");
            phoneVertex.setProperty("number", phone.getNumber());
            phoneVertexList.add(phoneVertex);
        }

        final OVertex profileVertex = dbSession.newVertex("Profile");
        profileVertex.setProperty("name", userProfile.getName());
        profileVertex.setProperty("phone", phoneVertexList, OType.EMBEDDEDLIST);

        profileVertex.save();
    }

根据位于以下位置的文档，我不清楚什么 https://orientdb.com/docs/last/general/Types.html代表EMBEDDEDLIST 应该是Java类型 List
