java - 解析 Hibernate Man.hbm.xml 时出错

Question

我无法运行我的 hibernate 应用程序。我经常收到此错误:

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/C:/Users/MAG/.m2/repository/org/slf4j/slf4j-jdk14/1.7.2/slf4j-jdk14-1.7.2.jar!/org/slf4j/impl/StaticLoggerBinder.class]

我的程序的想法是:Man 是Owner 和Renter 的父类(super class)。
业主可以拥有多个单位，但单位只能有一个业主。
Renter 可以有多个 RenterBill，但 RenterBill 可以有一个 Renter。
承租人可以有很多公寓，公寓也可以有很多承租人。

我的 Man.hbm.xml:

<class name="Man" table="MEN">
    <id name="id" column="MAN_ID">
        <generator class="native" />
    </id>
    <property name="pesel" column="MAN_PESEL" />
    <property name="idNumber" column="MAN_ID_NUMBER" />
    <property name="email" column="MAN_EMAIL" />
    <property name="name" column="MAN_NAME" />
    <property name="surname" column="MAN_SURNAME" />
    <property name="telephoneNumber" column="MAN_TELEPHONE_NUMBER" />
    <many-to-one name="address" column="ADDRESS_ID" not-null="true" />

    <joined-subclass name="Owner" table="OWNERS">
        <key column="MAN_ID" />
        <property name="password" column="OWNER_PASSWORD" not-null="true" />
        <property name="seed" column="OWNER_SEED" not-null="true" />
        <set name="flats" table="OWNER_FLATS">
            <key column="MAN_ID" />
            <many-to-many name="flats" column="FLAT_ID" class="Flat" />
        </set>
    </joined-subclass>

    <joined-subclass name="Renter" table="RENTERS">
        <key column="MAN_ID" />
        <set name="flats" table="RENTER_FLATS">
            <key column="MAN_ID" />
            <many-to-many name="flats" column="FLAT_ID" class="Flat" />
        </set>
        <set name="bills" table="RENTER_BILLS">
            <key column="MAN_ID" />
            <many-to-one name="bills" column="RENTER_BILL_ID" class="RenterBill" />
        </set>
    </joined-subclass>
</class>

Java 类:人.java

import model.flat.Flat;

public class Owner extends Man implements Iterable<Flat> {

    private String password;
    private String seed;
    private Set<Flat> flats;

    /* getters setters */
}

租客.java

package model.man;

import model.bills.RenterBill;
import model.flat.Flat;

public class Renter extends Man {

    private Set<Flat> flats = new HashSet<Flat>();

尝试从多对多标签中删除“名称”属性。

更新

您也有一个映射为多对一的集合。这通常在您的 Java POJO 中显示为引用类的单个实例。您可能打算在那里使用一对多标记。
