"Không Persistence Unit Found" lỗi

Question

Tôi nhận được lỗi sau:

persistence.xml nằm trong src/META-INF, nằm trong đường dẫn xây dựng, vì vậy nó sẽ được tìm thấy đúng cách. Ai có ý tưởng gì không?

Answer 1

Tôi cũng thường đặt tệp persistence.xml trong thư mục tài nguyên /src/main/resouces/META-INF/persistence.xml vì tôi nhớ các vấn đề trong bản dựng không sao chép tài nguyên vào thư mục đầu ra.

Tôi chỉ có một cái nhìn vào cấu hình của chúng tôi và có vẻ hơi khác một chút:

<!-- 
    - Drives transactions using local JPA APIs 
--> 
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> 
    <property name="entityManagerFactory" ref="entityManagerFactory"/> 
</bean> 

<tx:annotation-driven mode="aspectj" proxy-target-class="true" /> 

<!-- 
    Custom PersistenceUnitManager, that reads all persistence.xml files in the 
    classpath and merges them to one single virtual persistence.xml. 

    In order to operate properly, all persistence.xml have to define the same 
    persistence unit name. 
--> 
<bean id="persistenceUnitManager" class="de.cware.cweb.jpa.MergingPersistenceUnitManager"> 
    <property name="persistenceXmlLocations"> 
     <list> 
      <value>classpath*:META-INF/persistence.xml</value> 
     </list> 
    </property> 
    <property name="defaultDataSource" ref="dataSource"/> 
</bean> 

<bean id="jpaTemplate" class="org.springframework.orm.jpa.JpaTemplate"> 
    <property name="entityManagerFactory" ref="entityManagerFactory"/> 
</bean> 

<!--

    <property name="defaultTransactionIsolation" value="#{ T(java.sql.Connection).TRANSACTION_READ_COMMITTED}"/> 
</bean> 

Hope this helps :-)

Answer 2

• giữ persistence.xml của bạn trong WEB-INF/classes/META-INF/persistence.xml

• xóa confl hibernate icting thư viện ....

• remove ngủ đông - 3.2.0 jar nếu ngủ đông lõi là có

Answer 3

Lỗi này có thể xảy ra nếu bạn có một hibernate ánh xạ lớp học với các mối quan hệ với một lớp không ánh xạ, một giải pháp là để kiểm tra các mục quan hệ như @transient (hibernate sẽ bỏ qua nó, sử dụng này chỉ để kiểm tra nếu đây là lỗi, và sau đó ánh xạ các lớp liên quan). Ví dụ:

@Entity 
public class City { 

@Id 
@GeneratedValue(strategy=GenerationType.AUTO) 
private int id; 

private String name; 

@Transient 
private State state; 

public int getId() { 
    return id; 
} 

public void setId(int id) { 
    this.id = id; 
} 

public String getName() { 
    return name; 
} 

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

public State getState() { 
    return state; 
} 

public void setState(State state) { 
    this.state = state; 
} 

} 

Và đây là lớp học không ánh xạ có thể cung cấp cho các lỗi:

public class State { 

private String name; 

} 

Answer 4

nơi persistence.xml trong một thư mục nguồn /src/main/resouces/META-INF/persistence.xml đối với tôi nó của công việc này giải pháp
