@Configuration
@ImportResource("classpath:config.xml")
public class StoreConfig {
@Value("${jdbc.url}")
private String url;
@Value("${jdbc.username}")
private String username;
@Value("${jdbc.password}")
private String password;
@Bean
public MyDriverManager myDriverManager(){
return new MyDriverManager(url,username,password);
}
}
@Value 不需要get、set方法
ConfigurationProperties 注解,是需要的,他能帮你自动将配置文件的对应的 prefix开头的属性,注入。
@ConfigurationProperties(locations = "classpath:mail.properties",
ignoreUnknownFields = false,
prefix = "mail")
public class MailProperties {
public static class Smtp {
private boolean auth;
private boolean starttlsEnable;
// ... getters and setters
}
@NotBlank private String host;
private int port;
private String from;
private String username;
private String password;
@NotNull private Smtp smtp;
// ... getters and setters
}
mail.host=localhost
mail.port=25
mail.smtp.auth=false
mail.smtp.starttls-enable=false
mail.from=me@localhost
mail.username=
mail.password=
