Question

我有一个项目，我使用Spring-data-jpa和Hibernate，我正在编写一个在内存数据库中使用H2的集成测试。

在我的数据库脚本中，创建表后，我实际上运行了一些插入语句

    <?php
// Add the code below to your theme's functions.php file to add a confirm password field on the register form under My Accounts.
add_filter('woocommerce_registration_errors', 'registration_errors_validation', 10,3);
function registration_errors_validation($reg_errors, $sanitized_user_login, $user_email) {
    global $woocommerce;
    extract( $_POST );
    if ( strcmp( $password, $password2 ) !== 0 ) {
        return new WP_Error( 'registration-error', __( 'Passwords do not match.', 'woocommerce' ) );
    }
    return $reg_errors;
}
add_action( 'woocommerce_register_form', 'wc_register_form_password_repeat' );
function wc_register_form_password_repeat() {
    ?>
    <p class="form-row form-row-wide">
        <label for="reg_password2"><?php _e( 'Password Repeat', 'woocommerce' ); ?> <span class="required">*</span></label>
        <input type="password" class="input-text" name="password2" id="reg_password2" value="<?php if ( ! empty( $_POST['password2'] ) ) echo esc_attr( $_POST['password2'] ); ?>" />
    </p>
    <?php
}
?>

运行我的集成测试后，我看到返回了4个条目而不是2个。

日志证实测试是初始化数据源两次，我想了解原因。任何帮助将不胜感激。

在我的Spring配置文件中，用@EnableJpaRepositories注释，然后我创建了持久性相关的bean，如下所示

INSERT INTO COST (paymentType, costValue, costCategory) VALUES ('INTERNATIONAL', 100, 'LICENSES');
INSERT INTO COST (paymentType, costValue, costCategory) VALUES ('INTERNATIONAL', 20, 'HARDWARE');

    @Bean
public JpaTransactionManager transactionManager() {
    if (transactionManager == null) {
        transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(entityManagerFactory().getObject());
    }
    return transactionManager;
}

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
    if (entityManagerFactoryBean == null) {

        entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
        entityManagerFactoryBean.setDataSource(dataSource());
        entityManagerFactoryBean.setPersistenceProviderClass(HibernatePersistenceProvider.class);
        entityManagerFactoryBean.setPackagesToScan(env.getRequiredProperty(ENTITYMANAGER_PACKAGES_TO_SCAN));
        entityManagerFactoryBean.setJpaProperties(hibProperties());      
    }
    return entityManagerFactoryBean;
}

@Bean
public DriverManagerDataSource dataSource() {

    if (dataSource == null) {
        dataSource = new DriverManagerDataSource();

        dataSource.setDriverClassName(env.getRequiredProperty(DATABASE_DRIVER));
        dataSource.setUrl(env.getRequiredProperty(DATABASE_URL));
        dataSource.setUsername(env.getRequiredProperty(DATABASE_USERNAME));
        dataSource.setPassword(env.getRequiredProperty(DATABASE_PASSWORD));
    }
    return dataSource;
}

Answer 1

从db.url属性中删除'DB_CLOSE_DELAY = -1'后，我开始获取正确数量的数据行;这是2。

但是，我检查了日志，仍然创建了2个数据源实例，我不确定为什么实例没有被重用

日志行位于

Answer 2

您不需要创建自己的dataSource，Spring已经在这样做了。您的数据源是第二个。这就是您的脚本运行两次的原因，因为JDBC URL被调用了两次。

我建议：

1）删除dataSource bean。

2）将您的JDBC URL更改为

jdbc:h2:mem:test;DB_CLOSE_DELAY=-1"

3）将create-data.sql重命名为data.sql并将其添加到资源目录中，使其位于类路径中。

Spring应该完成其余的工作，请参阅here手册。
