Question

我有一个看起来像这样的课程。

@Repository("myService")
@Transactional
public class MyDaoImpl implements MyDao
{
@PersistenceContext(unitName="blPU")
protected EntityManager em;

@Resource(name="blEntityConfiguration")
protected EntityConfiguration entityConfiguration;

    @Override
    @Transactional
    public Person findPersonByUsername(String username)
    {       
        System.out.println("The entity manager is "+em);
                // ....
    }

}

以及位于persistence.xml

的src/main/resources/META-INF/persistence.xml

<persistence-unit name="blPU" transaction-type="RESOURCE_LOCAL">
    <non-jta-data-source>jdbc/web</non-jta-data-source>
    <class>com.mycompany.dao.MyDaoImpl</class>
    <exclude-unlisted-classes/>
<properties>
  <property name="hibernate.hbm2ddl.auto" value="update" />
  <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>
  <property name="hibernate.show_sql" value="true"/>
  <property name="hibernate.cache.use_second_level_cache" value="true"/>
  <property name="hibernate.cache.use_query_cache" value="true"/>
  <property name="hibernate.hbm2ddl.import_files" value="/sql/import_storage.sql"/>
</properties>
</persistence-unit>

但我收到以下错误..

[artifact:mvn] org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'blPU' is defined
[artifact:mvn]  at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeanDefinition(DefaultListableBeanFactory.java:568)

jta数据源声明如下..

 <Resource name="jdbc/web"
              auth="Container"
              type="javax.sql.DataSource"
              factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
              testWhileIdle="true"
              testOnBorrow="true"
              testOnReturn="false"
              validationQuery="SELECT 1"
              timeBetweenEvictionRunsMillis="30000"
              maxActive="15"
              maxIdle="10"
              minIdle="5"
              removeAbandonedTimeout="60"
              removeAbandoned="false"
              logAbandoned="true"
              minEvictableIdleTimeMillis="30000"
              jdbcInterceptors="org.apache.tomcat.jdbc.pool.interceptor.ConnectionState;org.apache.tomcat.jdbc.pool.interceptor.StatementFinalizer"
              username="${database.user}"
              password="${database.password}"
              driverClassName="${database.driver}"
              url="${database.url}"/>

Answer 1

将以下内容添加到applicationContext.xml解决了问题。

<bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"/>
<context:annotation-config/>

感谢@geoand的有用评论

NoSuchBeanDefinitionException - 没有定义名为blPU的bean - 无法注入EntityManager JPA
