是否可以将以下yaml文件作为Map<String, Map<String, String>
注入到Spring Boot应用程序中,其中tradeType
将是外部映射的键,而P和B将是内部映射的键值。
tradeType:
P: B
S: S
securityCode:
ICI: ICICI Bank
BOB: Bank of Baroda
BOA: Bank of America
BOS: Bank of Singapore
正如建议的那样,这是我班上的样子。
@Configuration
@PropertySource("file:data/referenceDataMapping.yaml")
@ConfigurationProperties(prefix = "map")
public class ReferenceDataMapping {
private final Logger logger = LoggerFactory.getLogger(this.getClass());
private Map<String, Map<String, String>> entries;
@Override
public String toString() {
if (entries != null) {
logger.info(entries.toString());
return entries.toString();
} else {
return null;
}
}
public Map<String, Map<String, String>> getEntries() {
return entries;
}
public void setEntries(Map<String, Map<String, String>> entries) {
this.entries = entries;
}
}
来自build.gradle

是。有可能。
@Configuration
@ConfigurationProperties(prefix="map")
public class Test {
private Map<String,Map<String,String>> entires;
public Map<String, Map<String, String>> getEntires() {
return entires;
}
public void setEntires(Map<String, Map<String, String>> entires) {
this.entires = entires;
}
}
application.yml :
map:
entires:
tradeType:
P: B
S: S
securityCode:
ICI: ICICI Bank
BOB: Bank of Baroda
BOA: Bank of America
BOS: Bank of Singapore
输出:
{tradeType={P=B, S=S}, securityCode={ICI=ICICI Bank, BOB=Bank of Baroda, BOA=Bank of America, BOS=Bank of Singapore}}
更新:
如本github-issue中所述。 @PropertySource不支持Yaml文件。在这种情况下,请遵循本指南PropertySource-with-yaml-files

如果YAML与application.yml位于不同的文件中,
@Component
public class YourClass {
private Map<String, String> tradeType;
private Map<String, String> securityCode;
public Map<String, String> getTradeType() {
return tradeType;
}
public Map<String, String> getSecurityCode() {
return securityCode;
}
@PostConstruct
public void yamlFactory() {
YamlMapFactoryBean factory = new YamlMapFactoryBean();
factory.setResources(new ClassPathResource("your.yml"));
tradeType = (Map<String, String>) factory.getObject().get("tradeType");
securityCode = (Map<String, String>) factory.getObject().get("securityCode");
}
}
