在多模块SpringBoot应用程序中扫描外部jar java数据源配置

我想询问如何配置SpringBoot应用程序以包括外部Jar Java数据源配置。实体类在外部Jar实体类中都用@Entity注释，存储库接口用@repository注释和Crudepository扩展。Lib模块打包为一个JAR文件，数据源用Java配置。WAR模块应该导入LIB-jar，并使用它从数据库中提取数据，数据源配置为jar本身

Maven构建提取

<groupId>com.sample.app</groupId>
<artifactId>App-war</artifactId>
<version>1.0.0-SNAPSHOT</version>
<packaging>war</packaging>

<dependencies>
        <dependency>
            <groupId>com.sample.lib</groupId>
            <artifactId>Lib-jar</artifactId>
            <type>jar</type>
        </dependency>
        <dependency>
            <groupId>com.penta.account</groupId>
            <artifactId>AccountService-jar</artifactId>
            <type>jar</type>
        </dependency>
    </dependencies>

所以我认为我应该导入Java数据源配置，然后使用它来存储要扫描的包。可以编译应用程序，但WAR中的组件未编译，导致spring引导使用默认登录页，并忽略WAR包中的任何自定义身份验证

LibDSConfig的数据源Java配置

@Configuration
@EnableJpaRepositories("com.sample.lib.repository")
public class LibDSConfig {

    // Other @Bean classes
    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
        em.setDataSource(local());
        em.setPackagesToScan(new String[]{com.sample.lib.entity});
        JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        em.setJpaVendorAdapter(vendorAdapter);
        em.setJpaProperties(additionalProperties());
        return em;
    }    
}

AppDSConfig的数据源Java配置

@Configuration
    @EnableJpaRepositories("com.sample.app.repository")
    public class AppDSConfig {
    
        // Other @Bean classes
        @Bean
        public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
            LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
            em.setDataSource(local());
            em.setPackagesToScan(new String[]{com.sample.app.entity});
            JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
            em.setJpaVendorAdapter(vendorAdapter);
            em.setJpaProperties(additionalProperties());
            return em;
        }    
    }

Springboot主java配置

@SpringBootApplication()
@ComponentScan({"com.sample.lib.entity","com.sample.lib.entity"})
@Import({
    AppDSConfig.class,
    LibDSConfig .class
})
public class Application{

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

我知道@ComponentScan只扫描上面代码中配置的实体类。我想问一下，是否有其他解决方案可以导入外部jar java配置？

能否从应用程序中删除ComponentScan并查看是否工作正常？@sonus21如果我删除ComponentScan，Springboot将不会处理java数据源配置文件中的EnableJpaRepositories。如果我在springboot主应用程序中添加EnableJpaREpositories，它将不会抛出托管类型错误。@sonus21我刚刚发现我忘记在maven中导入模块的问题。无论如何，谢谢你的帮助！！干杯

@SpringBootApplication()
@ComponentScan({"com.sample.lib.entity","com.sample.lib.entity"})
@Import({
    AppDSConfig.class,
    LibDSConfig .class
})
public class Application{

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}
