这是我的应用程序:
public static void main( String[] args ) {
AnnotationConfigApplicationContext ctx = new AnnotationConfigApplicationContext(Config.class);
//run the importer
final ImportNewOrders importer = (ImportNewOrders) ApplicationContextProvider.getApplicationContext().getBean("importNewOrders");
importer.run();
//importer.runInBackground();
}
这是我的配置:
@Configuration
@ComponentScan(basePackages = {
"com.production"
})
@PropertySource(value = {
"classpath:/application.properties",
"classpath:/environment-${MY_ENVIRONMENT}.properties"
})
@EnableJpaRepositories("com.fettergroup.production.repositories")
@EnableTransactionManagement
public class Config {
.... skipping things that aren't relevant
@Bean
public ImportNewOrders importNewOrders() {
return new ImportNewOrders();
}
这是我的课...
@Component
public class ImportNewOrders implements Task {
private final static Logger logger = Logger.getLogger(ImportNewOrders.class.getName());
@Autowired
private OrderService orderService;
@Autowired
private ImportOrderRequest importOrderRequest;
@Value("${api.user}")
private String apiUser;
@Value("${api.password}")
private String apiPassword;
@Value("${api.orders.pingFrequency}")
private String pingFrequency;
最后是application.properties
:
# ------------------- Application settings -------------------
#Base URL to the API application
api.baseUrl=http://localhost:9998
#Unique token used to authenticate this vendor
api.vendor.token=asdf
#API credentials
api.user=myuser
api.password=mypassword
#How often to check for new orders; frequency is in seconds
api.orders.pingFrequency=60
这在一两个小时前有效,现在决定它不喜欢这些值。我不知道为什么。一切对我来说都是正确的。
更新
@Configuration
@ComponentScan(basePackages = {
"com.production"
})
@PropertySource(value = {
"classpath:/application.properties",
"classpath:/environment-${MY_ENVIRONMENT}.properties"
})
@EnableJpaRepositories("com.production.repositories")
@EnableTransactionManagement
public class Config {
@Value("${db.url}")
private static String PROPERTY_DATABASE_URL;
@Bean
public DataSource dataSource() {
MysqlDataSource dataSource = new MysqlDataSource();
dataSource.setUrl(PROPERTY_DATABASE_URL); //is null
/*dataSource.setUser(environment.getRequiredProperty(PROPERTY_NAME_DATABASE_USER));
dataSource.setPassword(environment.getRequiredProperty(PROPERTY_NAME_DATABASE_PASSWORD));*/
return dataSource;
}
@Bean
public PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer () {
return new PropertySourcesPlaceholderConfigurer();
}
}
