我有一个带有 spring 数据 jpa 1.2.0.RELEASE 的 spring 3.2.0.M2 设置。
我也有java配置。这是我的存储库配置类。
@Configuration
@EnableJpaRepositories(basePackages = {"xxx.xxx.xxx.core.dao"})
@EnableTransactionManagement
public class Repository {
@Bean
public DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName("com.mysql.jdbc.Driver");
dataSource.setUrl("jdbc:mysql://localhost:3306/xxxx");
dataSource.setUsername("xxxx");
dataSource.setPassword("xxxx");
return dataSource;
}
@Bean
public EntityManagerFactory entityManagerFactory() {
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
vendorAdapter.setGenerateDdl(true);
LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
factory.setJpaVendorAdapter(vendorAdapter);
factory.setPackagesToScan("xx.xxxx.xxxx.xxxx.domain");
factory.setDataSource(dataSource());
factory.afterPropertiesSet();
return factory.getObject();
}
@Bean
public PlatformTransactionManager transactionManager() {
JpaTransactionManager txManager = new JpaTransactionManager();
txManager.setEntityManagerFactory(entityManagerFactory());
return txManager;
}
当我部署我的应用程序时，出现以下异常:
(org.springframework.web.context.ContextLoader:307) - Context initialization failed

当我删除 @EnableJpaRepositores 注释时，它起作用了。至少我是这么认为的，因为我的应用程序上下文将加载，但它会说我使用了依赖注入(inject)。当然是通过删除注释来实现的。
有人可以帮帮我吗？
最佳答案
我遇到了同样的问题，发现这是因为我的 中有 .spring-data-jpa 和 spring-data-commons-core 作为依赖项pom.xml
</dependencies>
...
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-commons-core</artifactId>
<version>1.3.2.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-jpa</artifactId>
<version>1.2.0.RELEASE</version>
</dependency>
...
</dependencies>
删除 spring-data-commons-core 依赖项，然后仅使用 spring-data-jpa 依赖项修复它。
