Ошибка создания бина

Я пытаюсь настроить Hibernate, Spring Data JPA для MySQL. Я был бы очень признателен, если бы кто-нибудь мог указать, что мне не хватает? Кроме того, мне не удалось найти причину IllegalArgumentException.Ошибка создания бина

Учитывая, что вы используете Spring бутс, что цель 'DatabaseConfig'? Spring Boot автоматически настроит все для вас. Вы пытаетесь каким-то образом настроить поведение загрузки по умолчанию? –

Спасибо @ Энди Уилкинсон. Я осознал свою ошибку. – Sp1

Согласие на DefaultPersistenceUnitManager.java: линия 522 Проблема заключается в том, что вы Ждут» t установить packagesToScan

for (String pkg : this.packagesToScan) { 
 
\t \t \t \t try { 
 
\t \t \t \t \t String pattern = ResourcePatternResolver.CLASSPATH_ALL_URL_PREFIX + 
 
\t \t \t \t \t \t \t ClassUtils.convertClassNameToResourcePath(pkg) + CLASS_RESOURCE_PATTERN;

public static String convertClassNameToResourcePath(String className) { 
    Assert.notNull(className, "Class name must not be null"); 
    return className.replace(PACKAGE_SEPARATOR, PATH_SEPARATOR); 
}

Таким образом, вы можете проверить вам код в em.setPackagesToScan (env.getProperty ("em.setPackagesToScan"));

env.getProperty ("em.setPackagesToScan") равно нулю;

Спасибо @ H.Hao. Это было очень полезно. Хотя, я изменил файл application.properties и использовал spring.datasource. * И spring.jpa. * Свойства из [link] (http://docs.spring.io/spring-boot/docs/current/reference/html /common-application-properties.html) и удалил 'DatabaseConfig' – Sp1

вы можете иметь класс Java в ваш пакет, который не является JPA/Entity
