java - 带注释的 bean 配置看不到 XML 配置中的 bean

Question

我真的很困惑。我有带有 Spring Security 的网络应用程序。我有带有嵌入式数据库的database.xml配置:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jdbc="http://www.springframework.org/schema/jdbc"
    xsi:schemaLocation="http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-4.1.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">


    <jdbc:embedded-database id="dataSource" type="H2" />

</beans>

我还有 PersistenceJpaConfig:

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories("pl.springsecurity.repositories")
public class PersistenceJpaConfig {

    @Autowired
    private DataSource dataSource;

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean entityManager = new LocalContainerEntityManagerFactoryBean();
        entityManager.setDataSource(dataSource);
        entityManager.setPackagesToScan(new String[] { "pl.springsecurity.domain" });

        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        vendorAdapter.setGenerateDdl(true);
        //vendorAdapter.setShowSql(true);
        entityManager.setJpaVendorAdapter(vendorAdapter);
        return entityManager;
    }

    @Bean
    public PlatformTransactionManager transactionManager(EntityManagerFactory emf) {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(emf);
        return transactionManager;
    }

当我的 Spring Security 配置位于 xml bean 文件中并且 Spring Security 过滤器在 web.xml 中声明时，效果很好。

但是...由于我尝试将 Spring Security 配置移至 Java 类，这意味着 web.xml 中不再需要过滤器，并且由于我创建了 AbstractSecurityWebApplicationInitializer，Spring 无法找到在 database.xml 中删除的 DataSource bean 并且将其绑定(bind)到我的 Jpa 配置中。我真的很困惑为什么......

这是我的堆栈跟踪:

大家有什么想法吗？

您必须加载 x​​ml。请参阅docs

您可以使用@ImportXml("classpath:com/company/app/datasource-config.xml")在你的配置类上
