新しい Spring 3.2.4 アプリケーションの開発を開始し、以前使用していた XML ファイルの代わりに Java ベースの構成を使用しようとしています。ただし、移行に問題があります。
XML を使用して、次のようにコーディングします。
<!-- application datasource -->
<bean id="dataSource.jndi" class="org.springframework.jndi.JndiObjectFactoryBean" scope="singleton" lazy-init="true">
<property name="jndiName" value="java:comp/env/jdbc/liment" />
</bean>
<bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>
<tx:annotation-driven mode="aspectj" transaction-manager="transactionManager"/>
<bean class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" id="entityManagerFactory">
<property name="persistenceUnitName" value="persistenceUnit"/>
<property name="dataSource" ref="dataSource.jndi"/>
</bean>
ただし、Javaでこれを行う方法を理解しようとして、私は非常に行き詰まっています。構成を複製しようとしていますが、問題が発生しています:
@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages={"com.ia"})
public class AppConfigJPA {
@Bean
public DataSource dataSource() {
// configure and return the necessary JDBC DataSource
JndiObjectFactoryBean dataSource = new JndiObjectFactoryBean();
dataSource.setJndiName("java:comp/env/jdbc/liment");
try {
dataSource.afterPropertiesSet();
} catch (IllegalArgumentException | NamingException e) {
// rethrow
throw new RuntimeException(e);
}
return (DataSource)dataSource.getObject();
}
@Bean
public EntityManagerFactory entityManagerFactory(){
LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
emf.setPersistenceUnitName("persistenceUnit");
emf.setDataSource(dataSource());
emf.afterPropertiesSet
return emf.getObject();
}
@Bean
public PlatformTransactionManager transactionManager() {
return new JpaTransactionManager(entityManagerFactory());
}
}
ただし、次のエラー メッセージが表示されます。
Caused by: java.lang.IllegalStateException: No persistence exception translators found in bean factory. Cannot perform exception translation.

私は何が欠けているか、間違っていますか?

@SotiriosDelimanolis の応答に従って、次のようにコードを変更しました。
@Autowired DataSource dataSource;
@Autowired EntityManagerFactory entityManagerFactory;
@Bean
public JndiObjectFactoryBean dataSource() {
// configure and return the necessary JDBC DataSource
JndiObjectFactoryBean dataSource = new JndiObjectFactoryBean();
dataSource.setJndiName("java:comp/env/jdbc/josak");
return dataSource;
}
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(){
LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
emf.setPersistenceUnitName("persistenceUnit");
emf.setDataSource(dataSource);
return emf;
}
@Bean
public PlatformTransactionManager transactionManager() {
return new JpaTransactionManager(entityManagerFactory);
}
しかし、代わりに Autowired 例外が発生しています:
