我是这个.yml文件:
template: Hello, testapp!
storage:
storageUri: ****************
storageAccessKey: ****************
storageSecretKey: *******************
buckets:
"one": one-buck-name
"second": second-buck-name
buckets:
- tag: one
name: one-buck-name
- tag: second
name: second-buck-name
one:
bucket: one-buck-name
second:
bucket: second-buck-name
在" storageSecretKey"我有三种不同的方式来定义我的存储桶的配置。 所以我用java解析这些配置有很多问题。
首次配置时,我使用过:
@NotNull private ImmutableMap<String, String> buckets = ImmutableMap.of();
出现此错误:
testapp.yml has an error: * Unrecognized field at: storage.buckets
Did you mean?:
- storageUri
- storageAccessKey
- storageSecretKey
使用第二种配置(仅适用):
@Valid @NotNull private List buckets = Lists.newArrayList(); public static class Bucket {
@Valid
@NotNull
@JsonProperty
private String tag;
@Valid
@NotNull
@JsonProperty
private String name;
public Bucket(){}
public String getTag() {
return tag;
}
public void setTag(String tag) {
this.tag = tag;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
最后,对于第三种配置:
@Valid
@NotNull
@JsonProperty
private One one;
@Valid
@NotNull
@JsonProperty
private Second second;
public class One {
@Valid
@NotNull
@JsonProperty
private String bucket;
public String getBucket() {
return bucket;
}
}
public class Second {
@Valid
@NotNull
@JsonProperty
private String bucket;
public String getBucket() {
return bucket;
}
}
出现此错误:
testapp.yml has an error:
* Failed to parse configuration at: storage.one.bucket; Can not deserialize instance of java.lang.String out of END_OBJECT token
at [Source: N/A; line: -1, column: -1] (through reference chain: com.testapp.configurations.AppConfiguration["storage"]->com.testapp.configurations.StorageConfiguration["chat"]->com.testapp.configurations.One["one"])
注意:第三种配置与dropwizard 0.6.2完美配合。

解析这个该死的存储配置的正确方法在哪里?
答案 0 :(得分:1)
处理它的最好方法可能就像你的第二个例子。你可以做这样简单的事情(请注意,在我的.yml文件中,我在根目录中有buckets
- 仅用于示例目的。)
example.yml
buckets:
- name: name1
properties:
prop1: moo
prop2: meep
prop3: momp
- name: name2
properties:
prop1: axe
prop2: farid
prop3: tom
SampleConfiguration.java
public class SampleConfiguration extends Configuration
{
@NotNull
@JsonProperty
public List<Bucket> buckets;
public static class Bucket {
@NotNull
@JsonProperty
private String name;
@NotNull
@JsonProperty
private Map<String, String> properties;
public String getBucketName() {
return this.name;
}
public Map<String, String> getProperties() {
return this.properties;
}
}
}
另外,如果
,你的第三个适合我one:
bucket: one-buck-name
second:
bucket: second-buck-name
处于根级别。如果您正在使用storage:
,请务必将所有这些嵌套在您的存储POJO中。
