当我尝试使用 javaconfig 实例化 entityManagerFactory bean 时，我参考了以下 spring 文档部分。

我的应用程序启动正常，但是当我打开页面时，出现以下异常：

org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [javax.persistence.EntityManagerFactory] is defined
    org.springframework.beans.factory.support.DefaultListableBeanFactory.getBean(DefaultListableBeanFactory.java:295)
    org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:1125)

    org.springframework.web.filter.HiddenHttpMethodFilter.doFilterInternal(HiddenHttpMethodFilter.java:77)
    org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:107)

我不确定我的数据/JPA 配置有什么问题：

@Configuration
@EnableTransactionManagement(mode = AdviceMode.ASPECTJ)
public class DataConfiguration {

    @Value("${database.driverClassName}")
    private String driverClassName;

    @Value("${database.url}")
    private String url;

    @Value("${database.username}")
    private String username;

    @Value("${database.password}")
    private String password;

    @Value("${database.validationQuery}")
    private String validationQuery;

    @Bean
    public DataSource dataSource() {
        BasicDataSource dataSource = new BasicDataSource();
        dataSource.setDriverClassName(driverClassName);
        dataSource.setUrl(url);
        dataSource.setUsername(username);
        dataSource.setPassword(password);
        dataSource.setTestOnBorrow(Boolean.TRUE);
        dataSource.setTestOnReturn(Boolean.TRUE);
        dataSource.setTestWhileIdle(Boolean.TRUE);
        dataSource.setTimeBetweenEvictionRunsMillis(1800000);
        dataSource.setNumTestsPerEvictionRun(3);
        dataSource.setMinEvictableIdleTimeMillis(1800000);
        dataSource.setValidationQuery(validationQuery);
        dataSource.setMaxActive(5);
        dataSource.setLogAbandoned(Boolean.TRUE);
        dataSource.setRemoveAbandoned(Boolean.TRUE);
        dataSource.setRemoveAbandonedTimeout(10);
        return dataSource;
    }

    @Bean
    public JpaTransactionManager transactionManager() {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(entityManagerFactory().getObject());
        return transactionManager;
    }

    @Bean
    public HibernateJpaVendorAdapter jpaVendorAdapter() {
        return new HibernateJpaVendorAdapter();
    }

    @Bean
    public HibernatePersistence persistenceProvider() {
        return new HibernatePersistence();
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
        entityManagerFactoryBean.setPackagesToScan("com.bignibou.domain");
        entityManagerFactoryBean.setDataSource(dataSource());
        entityManagerFactoryBean.setPersistenceProvider(persistenceProvider());
        entityManagerFactoryBean.setJpaVendorAdapter(jpaVendorAdapter());
        entityManagerFactoryBean.setJpaPropertyMap(propertiesMap());
        //entityManagerFactoryBean.afterPropertiesSet();
        return entityManagerFactoryBean;
    }

    public Map<String, String> propertiesMap() {
        Map<String, String> propertiesMap = new HashMap<>();
        propertiesMap.put("hibernate.dialect", "org.hibernate.dialect.MySQL5InnoDBDialect");
        propertiesMap.put("hibernate.hbm2ddl.auto", "update");
        propertiesMap.put("hibernate.ejb.naming_strategy", "org.hibernate.cfg.ImprovedNamingStrategy");
        propertiesMap.put("hibernate.connection.charSet", "UTF-8");
        propertiesMap.put("hibernate.show_sql", "true");
        propertiesMap.put("hibernate.format_sql", "true");
        propertiesMap.put("hibernate.use_sql_comments", "true");
        return propertiesMap;
    }

    @Bean
    public HibernateExceptionTranslator hibernateExceptionTranslator() {
        return new HibernateExceptionTranslator();
    }

}

有人可以帮忙吗？

编辑：考虑到 Marten 的评论，我改变了我的 webApplicationInitializer 如下：

public class WebAppInitializer implements WebApplicationInitializer {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
        rootContext.register(BaseConfiguration.class);
        rootContext.setConfigLocations(new String[] { "classpath*:META-INF/spring/applicationContext*.xml" });

        servletContext.addListener(new ContextLoaderListener(rootContext));
        servletContext.addListener(new RequestContextListener());
        servletContext.addListener(new HttpSessionEventPublisher());

        servletContext.setInitParameter("defaultHtmlEscape", "true");

        FilterRegistration.Dynamic fr;

        fr = servletContext.addFilter("encodingFilter", new CharacterEncodingFilter());
        fr.setAsyncSupported(Boolean.TRUE);
        fr.setInitParameter("encoding", "UTF-8");
        fr.setInitParameter("forceEncoding", "true");
        fr.addMappingForUrlPatterns(null, true, "/*");

        fr = servletContext.addFilter("hiddenHttpMethodFilter", new HiddenHttpMethodFilter());
        fr.setAsyncSupported(Boolean.TRUE);
        fr.addMappingForUrlPatterns(null, true, "/*");

        fr = servletContext.addFilter("Spring OpenEntityManagerInViewFilter", new OpenEntityManagerInViewFilter());
        fr.setAsyncSupported(Boolean.TRUE);
        fr.addMappingForUrlPatterns(null, true, "/*");

        fr = servletContext.addFilter("springSecurityFilterChain", new DelegatingFilterProxy());
        fr.setAsyncSupported(Boolean.TRUE);
        fr.addMappingForUrlPatterns(null, true, "/*");

        AnnotationConfigWebApplicationContext mvcContext = new AnnotationConfigWebApplicationContext();
        mvcContext.register(WebMvcConfig.class);

        ServletRegistration.Dynamic dispatcher = servletContext.addServlet("bignibou", new DispatcherServlet(mvcContext));
        dispatcher.setLoadOnStartup(1);
        dispatcher.addMapping("/");


    }
}

我原以为我可以：

  • 一个具有@Configuration 类和 xml 文件的 rootContext和
  • 带有 @Configuration 类的 mvcContext

不幸的是，它没有按预期工作：我仍然得到 BeanCreationException 和 NoSuchBeanDefinitionException ...

任何人有任何线索？

编辑2：我只使用一个@ImportResources 移动到所有javaconfig，以便导入一个xml 配置文件。
