spring boot 读取新增配置文件信息

1、在resources文件下创建配置文件database.properties

mongodb.uri=xxxxxxxxxx
mongodb.username=ceshi
mongodb.password=123456
mongodb.schema=xxxxx

2、在mogodb配置方法中读取配置文件信息

@Configuration  //等价于XML中配置bean
@PropertySource(value = "classpath:database.properties",ignoreResourceNotFound = true)
public class MongoDBConfig {
    @Value("${mongodb.schema}")
    private String databaseName;

    @Value("${mongodb.uri}")
    private String uri;

    @Value("${mongodb.username}")
    private String userName;

    @Value("${mongodb.password}")
    private String password;

    @Bean
    public MongoDbFactory mongoDbFactory() throws UnknownHostException {
        String uriStr="mongodb://"+userName+":"+password+"@"+uri+"/"+databaseName;
        System.out.println(uriStr);
        MongoClientURI mongoClientURI=new MongoClientURI(uriStr);
        MongoDbFactory mongoDbFactory=new SimpleMongoDbFactory(mongoClientURI);
        return mongoDbFactory;
    }
}
