我使用帶有@一起@EnableCaching註解噴射/ @自動裝配Autowired在@Configuration上課的時候發現了一個問題：春@EnableCaching與@噴射/ @自動裝配Autowired問題
@Configuration
@EnableCaching
public class CacheConfig {
@Inject
private DataSource dataSource;
@Bean
public CacheManager cacheManager(){
SimpleCacheManager cacheManager = new SimpleCacheManager();
cacheManager.setCaches(Arrays.asList(new ConcurrentMapCache("books")));
return cacheManager;
}
@Configuration
static class DevProfileConfig {
@Bean(destroyMethod = "shutdown")
public DataSource dataSource() {
EmbeddedDatabaseFactory factory = new EmbeddedDatabaseFactory();
factory.setDatabaseType(EmbeddedDatabaseType.HSQL);
return factory.getDatabase();
}
}
}
應用程序上下文啓動：
public class CacheConfigLauncher {
public static void main(String args[]){
ApplicationContext springAppContext = new AnnotationConfigApplicationContext(CacheConfig.class);
}
}
埃羅r：

但是，如果您註釋掉@ Inject'ed字段或@EnableCaching註釋配置將被引導而沒有錯誤！
它接縫就像一個bug對我來說。有人遇到同樣的問題，或者我錯過了smth？
謝謝
