Spring Boot 2.0.0 M6-添加休眠拦截器 [英] Spring Boot 2.0.0 M6 - Add Hibernate Interceptor

问题描述

从Spring Boot 2.0.0 M2升级到2.0.0 M6后，我的Hibernate拦截器实现不再起作用.

After upgrade from Spring Boot 2.0.0 M2 to 2.0.0 M6 my Hibernate interceptor implementation don't work anymore.

我以前的实现方式:

@Configuration
public class HibernateConfiguration extends HibernateJpaAutoConfiguration {

    private HibernateStatisticsInterceptor hibernateStatisticsInterceptor;

    public HibernateConfiguration(DataSource dataSource, JpaProperties jpaProperties, ObjectProvider<JtaTransactionManager> jtaTransactionManager, ObjectProvider<TransactionManagerCustomizers> transactionManagerCustomizers, ObjectProvider<List<SchemaManagementProvider>> providers, HibernateStatisticsInterceptor hibernateStatisticsInterceptor) {
        super(dataSource, jpaProperties, jtaTransactionManager, transactionManagerCustomizers, providers);
        this.hibernateStatisticsInterceptor = hibernateStatisticsInterceptor;
    }

    @Override
    protected void customizeVendorProperties(Map<String, Object> vendorProperties) {
        vendorProperties.put("hibernate.session_factory.interceptor", hibernateStatisticsInterceptor);
    }
}

但是对于M5或M6，HibernateJpaAutoConfiguration类已更改，并且不再扩展JpaBaseConfiguration.

But with M5 or M6 the HibernateJpaAutoConfiguration class changed and extends JpaBaseConfiguration no more.

我尝试为每个YAML配置文件添加拦截器，但是它不起作用.

I try to add my interceptor per YAML-Configuration file, but it's not working.

我的拦截器:

@Component("hibernateStatisticsInterceptor")
public class HibernateStatisticsInterceptor extends EmptyInterceptor {

    private static final long serialVersionUID = 5278832720227796822L;

    private ThreadLocal<Long> queryCount = new ThreadLocal<>();

    public void startCounter() {
        queryCount.set(0l);
    }

    public Long getQueryCount() {
        return queryCount.get();
    }

    public void clearCounter() {
        queryCount.remove();
    }

    @Override
    public String onPrepareStatement(String sql) {
        Long count = queryCount.get();
        if (count != null) {
            queryCount.set(count + 1);
        }
        return super.onPrepareStatement(sql);
    }

}

如何重新激活拦截器?

你好，

请阅读以下内容: https://github.com/spring-projects /spring-boot/commit/59d5ed58428d8cb6c6d9fb723d0e334fe3e7d9be (使用:HibernatePropertiesCustomizer接口)

Give this a read: https://github.com/spring-projects/spring-boot/commit/59d5ed58428d8cb6c6d9fb723d0e334fe3e7d9be (use: HibernatePropertiesCustomizer interface)

1. 实施.
2. @Override custom()方法，添加拦截器
3. 别忘了 @Lazy注入(如果使用内部bean)
4. 完成=>运行

1. Implement it.
2. @Override customize() method, add your interceptor
3. Don't forget to @Lazy inject in case of internal beans
4. Done => Run

希望这对您有用.

最后一点:总是更新您的Spring/Hibernate版本(尽可能使用最新版本)，随着新版本尝试尽可能减少配置，您将看到大多数代码将变得多余.可能.

As a final note: always update your Spring / Hibernate versions (use the latest as possible) and you will see that most code will become redundant as newer versions try to reduce the configurations as much as possible.
