我只是试图手动读取dropwizard配置文件与SnakeYAML问题从YAML文件中创建对象
我的代码如下所示：
FileReader reader = new FileReader("/Users/novotny/IdeaProjects/fingage-platform/config-local.yml");
Yaml yaml = new Yaml();
FingageConfiguration config = yaml.loadAs(reader, FingageConfiguration.class);
System.err.println(config);
FingageConfiguration样子：
public class FingageConfiguration extends Configuration {
@Valid
@NotNull
private String env;
@JsonProperty("env")
public String getEnv() {
return env;
}
而我的config-local.yml看起来像：
env: local
server:
requestLog:
timeZone: UTC
applicationConnectors:
- type: http
port: 9370
adminConnectors:
- type: http
port: 9371
我不明白为什么Dropwizard在构建对象时没有困难，但我似乎无法用SnakeYAML来做，或者我做错了什么？我得到以下以下错误：
Exception in thread "main" Cannot create property=server for JavaBean=FingageConfiguration{server=DefaultServerFactory{applicationConnectors=[[email protected]], adminConnectors=[[email protected]], adminMaxThreads=64, adminMinThreads=1, applicationContextPath=/, adminContextPath=/}, logging=DefaultLoggingFactory{level=INFO, loggers={}, appenders=[[email protected]]}}
in 'reader', line 1, column 1:
env: "local"
