Spring-引导配置

Question

我有一个带应用程序的spring boot应用程序。属性文件和spring数据jpa。在应用程序中，我有一个外部依赖项，需要加载外部Spring项目的bean，该项目具有基于xml的配置。外部xml有自己的组件扫描和spring jpa设置，可以与应用程序中提供该DB属性的其他DB进行交互。属性文件，我正在使用@ImportResources将其bean注入父应用程序。但是，当我在做这个spring时，jpa并没有加载接口存储库bean。

问题是它加载了xml的bean，但无法加载父项目的存储库bean。

Appconfig。班

@Configuration
@ComponentScan(basePackages = {"com.xx.xx"})
public class AppConfig {

}

配置属性。班

@Configuration
@Import({AppConfig.class})
@ImportResource("classpath:xx-context.xml")
public class ConfigProperties {

}

xx上下文。xml（示例）

<mvc:annotation-driven />

    <import resource="yy-repository.xml" />
    <import resource="classpath:zz-config.xml" />

    <context:component-scan base-package="com.yy.yy" />

    <bean id="bean_id" 
         //defination
    </bean>

    <bean>
        //defination
    </bean>

</beans>

MainApp.java

@SpringBootApplication
public class MainApp extends SpringBootServletInitializer {

例外

申请无法启动

描述：

在com中输入AARepo。xx。xx。服务。实施。yyImpl需要“com”类型的bean。xx。x、 存储库。找不到AARepo。

行动

考虑定义“com”类型的bean。xx。xx。存储库。您的配置中的AARepo`

@Configuration
@EnableTransactionManagement(proxyTargetClass = true)
@EnableJpaRepositories(basePackages = {"com.arcvideo.cloudagent.repo", "com.arcvideo.cloudagent.customer"})
@PropertySource("classpath:database.properties")

public class DatabaseConfig {

    @Autowired
    private Environment env;

    @Bean(destroyMethod = "close")
    DataSource dataSource() {
        HikariConfig dataSourceConfig = new HikariConfig();
        dataSourceConfig.setPoolName("springHikariCP");
        dataSourceConfig.setConnectionTestQuery("SELECT 1");
        dataSourceConfig.setDataSourceClassName(env.getProperty("hibernate.connection.driver_class"));
        Properties dataSourceProperties = new Properties();
        dataSourceProperties.put("url", env.getProperty("hibernate.connection.url"));
        dataSourceProperties.put("user", env.getProperty("hibernate.connection.username"));
        dataSourceProperties.put("password", env.getProperty("hibernate.connection.password"));
        dataSourceConfig.setDataSourceProperties(dataSourceProperties);

        return new HikariDataSource(dataSourceConfig);
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean entityManagerFactory = new LocalContainerEntityManagerFactoryBean();
        entityManagerFactory.setDataSource(dataSource());
        entityManagerFactory.setPackagesToScan(env.getProperty("entitymanager.packagesToScan"));

        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        entityManagerFactory.setJpaVendorAdapter(vendorAdapter);

        Properties additionalProperties = new Properties();
        additionalProperties.put("hibernate.dialect", env.getProperty("hibernate.dialect"));
        additionalProperties.put("hibernate.cache.use_query_cache", env.getProperty("hibernate.cache.use_query_cache"));
        additionalProperties.put("hibernate.cache.use_second_level_cache", env.getProperty("hibernate.cache.use_second_level_cache"));
        additionalProperties.put("hibernate.cache.region.factory_class", env.getProperty("hibernate.cache.region.factory_class"));
        additionalProperties.put("hibernate.autoReconnect", env.getProperty("hibernate.autoReconnect"));
        additionalProperties.put("hibernate.hbm2ddl.auto", env.getProperty("hibernate.hbm2ddl.auto"));
        additionalProperties.put("hibernate.show_sql", env.getProperty("hibernate.show_sql"));
        additionalProperties.put("hibernate.format_sql", env.getProperty("hibernate.format_sql"));
        additionalProperties.put("javax.persistence.sharedCache.mode", env.getProperty("javax.persistence.sharedCache.mode"));
        additionalProperties.put("hibernate.generate_statistics", env.getProperty("hibernate.generate_statistics"));
        entityManagerFactory.setJpaProperties(additionalProperties);

        return entityManagerFactory;
    }
}

Answer 2

Springboot似乎看不到您的Repo类。您可以尝试将以下内容添加到主应用程序类中：@EnableJpaRepositories（“com.xx.x.repository”）？！

---更新---

更新主应用程序中的完整配置。你能试试这个吗？！

@SpringBootApplication
@EnableJpaRepositories("com.xx.x.repository")
@EntityScan("com.xx.x.repository.entity")
public class MainApp extends SpringBootServletInitializer {

希望这有帮助。

使用AppConfigClass顶部的EnableAutoConfiguration
