Question

我正在开发一个项目，我需要在创建或更新实体时收到通知。但不幸的是，@RepositoryEventHandler没有用。所以我准备了一个简单的版本，但我也没有运气。下面，我已经编写了我认为重新生成问题所需的所有组件。

我的配置

@Configuration
@ComponentScan(basePackages = "db")
@EnableJpaRepositories(basePackages = {"db"})
//@EnableSpringDataWebSupport
public class Config {

@Bean
@Autowired
public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource) throws Exception {
    HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
    vendorAdapter.setShowSql(Boolean.TRUE);
    LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
    factory.setJpaVendorAdapter(vendorAdapter);

    factory.setPackagesToScan("db");
    factory.setDataSource(dataSource);
    factory.setJpaProperties(getHibernateProperties());
    return factory;
}

@Bean
public DataSource getDataSource() throws Exception {
    Properties p = new Properties();
    Class.forName("org.h2.Driver");
    p.put("driverClassName", "org.h2.Driver");
    p.put("user", "admin");
    p.put("password", "123");
    DataSource ds = new DriverManagerDataSource("jdbc:h2:~/desktop/test;", p);
    return ds;
}

@Bean(name = "transactionManager")
public PlatformTransactionManager getTransactionManager(DataSource ds) {
    DataSourceTransactionManager txManager = new DataSourceTransactionManager();
    try {
        txManager.setDataSource(getDataSource());
    } catch (Exception e) {
        e.printStackTrace();
    }
    return txManager;
}

private Properties getHibernateProperties() {
    Properties properties = new Properties();
    properties.put("hibernate.show_sql", "true");
    properties.put("hibernate.dialect", "org.hibernate.dialect.H2Dialect");
    properties.put("hibernate.hbm2ddl.auto", "create");
    properties.put("hibernate.connection.charSet", "UTF-8");
    properties.put("hibernate.id.new_generator_mappings", "false");
    properties.put("hibernate.max_fetch_depth", "3");

    properties.put("hibernate.connection.autocommit", "false");
    properties.put("hibernate.connection.release_mode", "on_close");

    return properties;
}

}

我的POJO定义：

@javax.persistence.Entity
public class Entity {
private static final long serialVersionUID = 3501352854892096642L;


@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private long id ;

private String name ;

public long getId() {
    return id;
}

public void setId(long id) {
    this.id = id;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}
}

我的存储库：

    @RepositoryRestResource
public interface EntityRep extends PagingAndSortingRepository<Entity,Long> {
}

最后，这是我的事件处理程序定义类：

@Component
@RepositoryEventHandler(Entity.class)
public class EventHandler {

    @HandleBeforeSave
    @HandleBeforeCreate
    public void doSomething(Entity e){
        System.out.println("Hi...");
    }
}

我应该注意到我正在使用Spring Data Rest 2.6.4，Hibernate 5.2.10.Final和Tomcat 8.5.12作为容器。此外，我在Web.xml中使用了以下配置：

<listener>
    <listener-class>
        org.springframework.web.context.ContextLoaderListener
    </listener-class>
</listener>

<context-param>
    <param-name>contextClass</param-name>
    <param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value>
</context-param>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>db</param-value>
</context-param>

<servlet>
    <servlet-name>rest</servlet-name>
    <servlet-class>org.springframework.data.rest.webmvc.RepositoryRestDispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>rest</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

提前感谢您的帮助。
