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> <init-param> <param-name>contextConfigLocation</param-name> <param-value> ru.mystamps.web.config.MvcConfig,ru.mystamps.web.config.DbConfig </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/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd 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:
