未找到Hibernate映射異常類

Question

我在這個關於hibernate映射的問題上工作了好幾個小時。我認爲錯誤可能是一個簡單的語法錯誤，但我找不到它！

我跑進了以下異常，當我執行我的代碼：

Initial SessionFactory creation failed.org.hibernate.MappingException: entity class not found: LegalFee 
Exception in thread "main" java.lang.ExceptionInInitializerError 
    at com.plm.dao.util.HibernateUtil.buildSessionFactory(HibernateUtil.java:33) 
    at com.plm.dao.util.HibernateUtil.getSessionFactory(HibernateUtil.java:39) 
    at com.plm.dao.AppTest.main(AppTest.java:15) 

首先，我使用Hibernate 4.2和Java 8和MariaDB的10

請參見下面的所有配置。

我的hibernate.cfg.xml，我刪除C3P0配置：

<hibernate-configuration> 
    <session-factory> 
     <!-- Database connection settings --> 
     <property name='connection.driver_class'>com.mysql.jdbc.Driver</property> 
     <property name='connection.url'>jdbc:mysql://localhost:3306/PokerLeagueManager</property> 
     <property name='connection.username'>root</property> 
     <property name='connection.password'>mypassword</property> 
     <property name="show_sql">true</property> 

     <!-- SQL dialect --> 
     <property name='dialect'>org.hibernate.dialect.MySQL5InnoDBDialect</property> 

     <!-- Enable Hibernate's automatic session context management --> 
     <property name="current_session_context_class">thread</property> 
     <!-- Disable the second-level cache --> 
     <property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property> 


     <!-- Echo all executed SQL to stdout --> 
     <property name='show_sql'>true</property> 

     <mapping resource="mappings/BlindStructure.hbm.xml"/> 
     <mapping resource="mappings/Tournament.hbm.xml"/> 
     <mapping resource="mappings/LegalFee.hbm.xml"/> 
    </session-factory> 
</hibernate-configuration> 

錯誤是LegalFee豆所以重點關注一下。 見legalFee的SQL創建表：

CREATE TABLE `legalFee` (
    `idFee` int(11) NOT NULL, 
    `shortName` varchar(50) NOT NULL, 
    `description` varchar(200) DEFAULT NULL, 
    `feePercent` int(11) DEFAULT NULL, 
    `feeFixed` int(11) DEFAULT NULL, 
    PRIMARY KEY (`idFee`) 
) ENGINE=InnoDB DEFAULT CHARSET=utf8; 

類：

public class LegalFee implements Serializable { 

/** 
* generated serial uid 
*/ 
private static final long serialVersionUID = -2259355205530727294L; 

private int idFee; 
private String shortName; 
private String description; 
private Integer feePercent; 
private Integer feeFixed; 
private Set<Tournament> tournaments = new HashSet<Tournament>(0); 

public LegalFee() { 
} 

public LegalFee(int idFee, String shortName) { 
    this.idFee = idFee; 
    this.shortName = shortName; 
} 

public LegalFee(int idFee, String shortName, String description, 
     Integer feePercent, Integer feeFixed, Set<Tournament> tournaments) { 
    this.idFee = idFee; 
    this.shortName = shortName; 
    this.description = description; 
    this.feePercent = feePercent; 
    this.feeFixed = feeFixed; 
    this.tournaments = tournaments; 
} 

public int getIdFee() { 
    return this.idFee; 
} 

public void setIdFee(int idFee) { 
    this.idFee = idFee; 
} 

public String getShortName() { 
    return this.shortName; 
} 

public void setShortName(String shortName) { 
    this.shortName = shortName; 
} 

public String getDescription() { 
    return this.description; 
} 

public void setDescription(String description) { 
    this.description = description; 
} 

public Integer getFeePercent() { 
    return this.feePercent; 
} 

public void setFeePercent(Integer feePercent) { 
    this.feePercent = feePercent; 
} 

public Integer getFeeFixed() { 
    return this.feeFixed; 
} 

public void setFeeFixed(Integer feeFixed) { 
    this.feeFixed = feeFixed; 
} 

public Set<Tournament> getTournaments() { 
    return this.tournaments; 
} 

public void setTournaments(Set<Tournament> tournaments) { 
    this.tournaments = tournaments; 
} 

} 

最後是LegalFee.hbm.xml：

<?xml version="1.0"?> 
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" 
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> 

<hibernate-mapping> 
    <class name="LegalFee" table="legalFee" catalog="PokerLeagueManager" optimistic-lock="version"> 
     <id name="idFee" type="int"> 
      <column name="idFee" /> 
      <generator class="identity" /> 
     </id> 
     <property name="shortName" type="string"> 
      <column name="shortName" length="50" not-null="true" /> 
     </property> 
     <property name="description" type="string"> 
      <column name="description" length="200" /> 
     </property> 
     <property name="feePercent" type="java.lang.Integer"> 
      <column name="feePercent" /> 
     </property> 
     <property name="feeFixed" type="java.lang.Integer"> 
      <column name="feeFixed" /> 
     </property> 
     <set name="tournaments" table="tournament" inverse="true" lazy="true" fetch="select"> 
      <key> 
       <column name="legalFee_feeId" /> 
      </key> 
      <one-to-many class="Tournament" /> 
     </set> 
    </class> 
</hibernate-mapping> 

感謝您的幫助。

如果您的LegalFee類不是默認包，您需要提供該類的完整分類名稱。例如「class name =」com.abc.xyx.LegalFee「table =」legalFee「」
