带注释的 bean 配置没有从 XML 配置中看到 bean

【问题标题】：Annotated bean config doesnt see bean from XML config带注释的 bean 配置没有从 XML 配置中看到 bean

【问题描述】：

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>

我也有 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 配置在 xml bean 文件中并且 Spring Security 过滤器在 web.xml 中声明时，这工作正常。

但是...由于我尝试将 Spring Security 配置移动到 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，因此 Spring 在 database.xml 中找不到 DataSource bean 和将其绑定到我的 Jpa 配置中。我真的很困惑为什么......

这是我的堆栈跟踪：

有什么想法吗？

【问题讨论】：

  • 你没有加载你的 xml...

标签： java spring spring-mvc spring-security spring-data-jpa


【解决方案1】：

您必须加载 x​​ml。见docs

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

【讨论】：

    【解决方案2】：

    使用@ImportResource 加载您的xml 文件。

    @Configuration
@ImportResource(locations = "classpath:/database.xml")
....
public class PersistenceJpaConfig {

    适当更改位置。
