java – Spring 3.1:DataSource没有自动连接到@Configuration类
我正在使用
Spring MVC 3.1.0M2并尝试将我的配置移动到java bean.但我遇到以下错误:
从web.xml映射: <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; } ... } 春/ 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> 我希望在导入datasource.xml之后创建bean dataSource,但我总是遇到这个错误. TIA 解决方法
我发现错误原因,只有在我手动定义PersistenceAnnotationBeanPostProcessor时才会发生错误:
@Bean public PersistenceAnnotationBeanPostProcessor persistenceAnnotationBeanPostProcessor() { // enable injection of EntityManager to beans with @PersistenceContext annotation return new PersistenceAnnotationBeanPostProcessor(); } 对不起,因为我没有在问题中发布完整的代码(因为我认为这个bean没关系).当我删除此定义时,一切都按预期工作.另外我发现在我的情况下这个bean已经注册了:
