Java – spring 3.1: datasource is not automatically connected to the @ configuration class

I am using spring MVC 3.1 0m2 and try to move my configuration to java bean But I encountered the following errors:

From the web XML Mapping:

<context-param>
    <param-name>spring.profiles.default</param-name>
    <param-value>dev</param-value>
</context-param>

<servlet>
    <servlet-name>spring</servlet-name>
    <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
    <init-param>
        <param-name>contextClass</param-name>
        <param-value>
            org.springframework.web.context.support.AnnotationConfigWebApplicationContext
        </param-value>
    </init-param>

        </param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

DbConfig. java:

@Configuration
@EnableTransactionManagement
@ImportResource("classpath:spring/datasource.xml")
public class DbConfig {

    @Autowired
    private DataSource dataSource;

    @Bean
    public JpaVendorAdapter jpaVendorAdapter() {
        final HibernateJpaVendorAdapter jpaVendorAdapter =
            new HibernateJpaVendorAdapter();

        jpaVendorAdapter.setDatabasePlatform(dialectClassName);
        jpaVendorAdapter.setShowsql(showsql);

        return jpaVendorAdapter;
    }

    @Bean
    public LocalContainerEntityManagerfactorybean entityManagerFactory() {
        final LocalContainerEntityManagerfactorybean entityManagerFactory =
            new LocalContainerEntityManagerfactorybean();

        entityManagerFactory.setJpaVendorAdapter(jpaVendorAdapter());
        entityManagerFactory.setDataSource(dataSource);

        final Map<String,String> jpaProperties = new HashMap<String,String>();
        jpaProperties.put("hibernate.format_sql",formatsql);
        jpaProperties.put("hibernate.connection.charset","UTF-8");
        jpaProperties.put("hibernate.hbm2ddl.auto",hbm2ddl);
        entityManagerFactory.setJpaPropertyMap(jpaProperties);

        return entityManagerFactory;
    }

    @Bean
    public PlatformTransactionManager transactionManager() {
        final JpaTransactionManager transactionManager =
            new JpaTransactionManager();

        transactionManager.setEntityManagerFactory(entityManagerFactory().getObject());

        return transactionManager;
    }

    ...
}

Spring / datasource xml:

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:jdbc="http://www.springframework.org/schema/jdbc"
    xsi:schemaLocation="http://www.springframework.org/schema/beans

    http://www.springframework.org/schema/jdbc
    http://www.springframework.org/schema/jdbc/spring-jdbc-3.1.xsd">

    <context:property-placeholder location="classpath:spring/database.properties" />

    <beans profile="dev">
        <bean id="dataSource"
            class="org.apache.commons.dbcp.BasicDataSource"
            destroy-method="close">
            <property name="driverClassName" value="${db.driverClassName}" />
            <property name="url" value="${db.url}" />
            <property name="username" value="${db.username}" />
            <property name="password" value="${db.password}" />
        </bean>
    </beans>

    <beans profile="test">
        <jdbc:embedded-database id="dataSource" type="Hsql">
            <jdbc:script location="classpath:test-data.sql" />
        </jdbc:embedded-database>
    </beans>

</beans>

I want to import datasource Create bean datasource after XML, but I always encounter this error

TIA

Solution

I found the cause of the error. The error occurs only when I manually define the persistenceannotationbeanpostprocessor:

@Bean
   public PersistenceAnnotationBeanPostProcessor persistenceAnnotationBeanPostProcessor() {
           // enable injection of EntityManager to beans with @PersistenceContext annotation
           return new PersistenceAnnotationBeanPostProcessor();
   }

Sorry, because I didn't release the complete code in the problem (because I think this bean doesn't matter) When I delete this definition, everything works as expected In addition, I found that in my case, this bean has been registered:

(quoted from the comments of org.springframework.orm/src/main/java/org/springframework/orm/jpa/support/persistenceannotationbeanpostprocessor.java)
