如何在Config类
中使用application.properties文件datasource.username =测试
Config.class
@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
entityManagerFactoryRef = "abcFactory",
transactionManagerRef = "abcmanager",
basePackages = { "com.emp.repository" })
public class EmpConfig {
@Value("${datasource.username}")
String username;
@Bean(name = "empDataSource")
public DataSource empDataSource(String url, String userName, String pwd) {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName("XXX");
dataSource.setUrl(url);
dataSource.setUsername(userName);
dataSource.setPassword(pwd);
return dataSource;
}
}
如何将属性传递到用户名设置字段。

取决于您初始化应用的方式,但通常会添加类似
的内容@EnableAutoConfiguration
@PropertySource("classpath:application.properties")
@ComponentScan
@SpringBootApplication
@EnableTransactionManagement
确保你的配置中有其中一个
@Bean
public static PropertySourcesPlaceholderConfigurer propertyPlaceholderConfigurer() {
return new PropertySourcesPlaceholderConfigurer();
}
然后你可以访问这样的值
@Value("${datasource.username}")
@NotNull //optional
String username;
