JSON unmarshalling to POJO and inserting - json

Question

I would like to unmarshal a json string to a pojo class.
I am reading it from an existing url:
https://builds.apache.org/job/Accumulo-1.5/api/json
I am using apache camel to unmarshal the url
#Component
public class RouteBuilder extends SpringRouteBuilder {
private Logger logger = LoggerFactory.getLogger(RouteBuilder.class);
#Override
public void configure() throws Exception {
logger.info("Configuring route");
//Properties die hij niet vindt in de klasse negeren
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.configure(DeserializationConfig.Feature.FAIL_ON_UNKNOWN_PROPERTIES, false);
DataFormat reportFormat = new JacksonDataFormat(objectMapper, HealthReport.class);
from("timer://foo?fixedRate=true&delay=0&period=2000&repeatCount=1")
.routeId("accumoloToJsonRoute")
.setHeader(Exchange.HTTP_METHOD, constant("GET"))
.to("https://builds.apache.org:443/job/Accumulo-1.5/api/json")
.convertBodyTo(String.class)
.unmarshal(reportFormat) //instance van Build
.log(LoggingLevel.DEBUG, "be.kdg.teamf", "Project: ${body}")
.to("hibernate:be.kdg.teamf.model.HealthReport");
}
}
So far so good. I would like to only insert the 'healthReport' node using hibernate annotations.
#XmlRootElement(name = "healthReport")
#JsonRootName(value = "healthReport")
#Entity(name = "healthreport")
public class HealthReport implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int Id;
#Column
#JsonProperty("description")
private String description;
#Column
#JsonProperty("iconUrl")
private String iconUrl;
#Column
#JsonProperty("score")
private int score;
public HealthReport() {
}
public HealthReport(int score, String iconUrl, String description) {
this.score = score;
this.iconUrl = iconUrl;
this.description = description;
}
public String getDescription() {
return description;
}
public String getIconUrl() {
return iconUrl;
}
public int getId() {
return Id;
}
public int getScore() {
return score;
}
public void setDescription(String description) {
this.description = description;
}
public void setIconUrl(String iconUrl) {
this.iconUrl = iconUrl;
}
public void setId(int id) {
Id = id;
}
public void setScore(int score) {
this.score = score;
}
}
This is where the problem is. It does not recognize the annotations
and only null values are inserted in my database
#XmlRootElement(name = "healthReport")
#JsonRootName(value = "healthReport")
Does anybody know how to fix this?
Thanks

Answer 1

Fixed it using a Processor for my Route
public class HealthReportProcessor implements Processor {
#Autowired
private ConfigurationService configurationService;
#Override
public void process(Exchange exchange) throws Exception {
ObjectMapper mapper = new ObjectMapper();
JsonNode root = mapper.readTree(exchange.getIn().getBody().toString());
ArrayNode report = (ArrayNode) root.get("healthReport");
int configId = configurationService.findJenkinsConfigurationByName(root.get("displayName").asText()).getId();
for (JsonNode node : report) {
JsonObject obj = new JsonObject();
obj.addProperty("description", node.get("description").asText());
obj.addProperty("iconUrl", node.get("iconUrl").asText());
obj.addProperty("score", node.get("score").asInt());
obj.addProperty("jenkinsConfig", configId);
exchange.getIn().setBody(obj.toString());
}
}
}
It is working but I think there is a better solution.
If you have a better solution please let me know ;)

Can you try this,
from("timer://foo?fixedRate=true&delay=0&period=2000&repeatCount=1")
.routeId("accumoloToJsonRoute")
.setHeader(Exchange.HTTP_METHOD,constant("GET"))
.to("https://builds.apache.org:443/job/Accumulo-1.5/apijson")
.unmarshal().json(JsonLibrary.Jackson, HealthReport.class)
And make sure the response params match the POJO fields.
Let me know if it works.
