基于弹簧MVC注释的多模块项目配置

我实现了两个基于maven的独立Web项目，使用Spring MVC，hibernate和Jax-RS实现。

但是我的要求改变了，现在我需要将这两个项目作为子项目合并到另一个项目中，即我们的父项目。所以我使用maven multimodule配置。

项目 1：父项目

<packaging>pom</packaging>
<modules>
    <module>../child1</module>
    <module>../child2</module>
</modules>

儿童 1：

<packaging>jar</packaging>
<parent>
    <groupId>com.xyz.alpha</groupId>
    <artifactId>parent</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <relativePath>../parent</relativePath>
</parent>

儿童 2：

<packaging>jar</packaging>

<dependency>
        <groupId>com.xyz.alpha</groupId>
        <artifactId>child1</artifactId>
        <version>2.0.2</version>
</dependency>
<parent>
    <groupId>com.xyz.alpha</groupId>
    <artifactId>parent</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <relativePath>../parent</relativePath>
</parent>

但是我需要在Java中配置项目，以便它将扫描父项目和子项目的组件并执行项目。目前，我对每个项目都有单独的配置，如下所示：

应用集成器.java

public class AppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class[] { AppConfig.class };
    }
 
    @Override
    protected Class<?>[] getServletConfigClasses() {
        return null;
    }
 
    @Override
    protected String[] getServletMappings() {
        return new String[] { "/" };
    }
}

应用配置.java

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.x.y")
public class AppConfig extends WebMvcConfigurerAdapter{
     
    @Bean
    public ViewResolver viewResolver() {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setViewClass(JstlView.class);
        viewResolver.setPrefix("/WEB-INF/views/");
        viewResolver.setSuffix(".jsp");
        return viewResolver;
    }
    
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**");
    }
    
    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }
    
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
      
    }
}

休眠配置.java

@Configuration
@EnableTransactionManagement
@ComponentScan({ "com.x.y.configuration" })
@PropertySource(value = { "classpath:application.properties" })
public class HibernateConfiguration {
 
    @Autowired
    private Environment environment;
 
    @Bean
    public LocalSessionFactoryBean sessionFactory() {
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource());
        sessionFactory.setPackagesToScan(new String[] { "com.x.y.model" });
        sessionFactory.setHibernateProperties(hibernateProperties());
        return sessionFactory;
     }
     
    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName"));
        dataSource.setUrl(environment.getRequiredProperty("jdbc.url"));
        dataSource.setUsername(environment.getRequiredProperty("jdbc.username"));
        dataSource.setPassword(environment.getRequiredProperty("jdbc.password"));
        return dataSource;
    }
     
    private Properties hibernateProperties() {
        Properties properties = new Properties();
        properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect"));
        properties.put("hibernate.show_sql", environment.getRequiredProperty("hibernate.show_sql"));
        properties.put("hibernate.format_sql", environment.getRequiredProperty("hibernate.format_sql"));
        properties.put("hibernate.hbm2ddl.auto", environment.getRequiredProperty("hibernate.hbm2ddl.auto"));
        return properties;        
    }
     
    @Bean
    @Autowired
    public HibernateTransactionManager transactionManager(SessionFactory s) {
       HibernateTransactionManager txManager = new HibernateTransactionManager();
       txManager.setSessionFactory(s);
       return txManager;
    }
}
