我是Java新手。
我正在尝试使用JsonSchema验证Json。我已经提到Java / Android-针对String模式验证String JSON ..我尝试使用#Tihamer代码,但遇到了JsonParserException,但我没有使用过它。
下面是我的代码
import java.util.Iterator;
import com.fasterxml.jackson.databind.JsonNode;
import com.github.fge.jackson.JsonLoader;
import com.github.fge.jsonschema.core.report.ProcessingMessage;
import com.github.fge.jsonschema.core.report.ProcessingReport;
import com.github.fge.jsonschema.main.JsonSchema;
import com.github.fge.jsonschema.main.JsonSchemaFactory;
public class JsonValidation {
public static void main(String[] args)
{
JsonValidation jv = new JsonValidation();
String jsonData = "{\"dispatcherMode\":\"standard\",\"noOfdispatcher\":\"3\",\"dispatcherInfo\":[{\"dispatcher\":\"Dispatcher 0 = 156.95.53.243:6108<--current\"},{\"dispatcher\":\"Dispatcher 1 = 156.95.53.220:6108\"},{\"dispatcher\":\"Dispatcher 2 = 172.26.41.113:6108\"}],\"noOfAuthServer\":\"3\",\"connected\":\"3\",\"authorizationInfo\":[{\"authServer\":\"authserver 0 = 172.26.41.114:6115(connected)<--current\",\"requests\":\"1503\",\"failures\":\"1\",\"queued\":\"0\",\"delay\":\"10225\"},{\"authServer\":\"authserver 1 = 156.95.53.220:6115(connected)\",\"requests\":\"10745\",\"failures\":\"0\",\"queued\":\"0\",\"delay\":\"5762\"},{\"authServer\":\"authserver 2 = 172.26.41.113:6115(connected)\",\"requests\":\"12545\",\"failures\":\"1\",\"queued\":\"0\",\"delay\":\"9756\"}],\"noOfCache\":\"2\",\"cacheInfo\":[{\"cacheNumber\":\"cache 0\",\"request\":\"0\",\"hits\":\"0\",\"entries\":\"0\",\"size\":\"10000\",\"ttl\":\"600sec\"},{\"cacheNumber\":\"cache 1\",\"request\":\"1\",\"hits\":\"1\",\"entries\":\"1\",\"size\":\"12000\",\"ttl\":\"300sec\"}]}";
String jsonSchema = "{\"type\": \"object\",\"properties\": {\"dispatcherMode\": {\"type\": \"string\"},\"noOfdispatcher\": {\"type\": \"string\"},\"dispatcherInfo\": {\"type\": \"array\",\"items\": [{\"type\": \"object\",\"properties\": {\"dispatcher\": {\"type\": \"string\"}}},{\"type\": \"object\",\"properties\": {\"dispatcher\": {\"type\": \"string\"}}},{\"type\": \"object\",\"properties\": {\"dispatcher\": {\"type\": \"string\"}}}]},\"noOfAuthServer\": {\"type\": \"string\"},\"connected\": {\"type\": \"string\"},\"authorizationInfo\": {\"type\": \"array\",\"items\": [{\"type\": \"object\",\"properties\": {\"authServer\": {\"type\": \"string\"},\"requests\": {\"type\": \"string\"},\"failures\": {\"type\": \"string\"},\"queued\": {\"type\": \"string\"},\"delay\": {\"type\": \"string\"}}},{\"type\": \"object\",\"properties\": {\"authServer\": {\"type\": \"string\"},\"requests\": {\"type\": \"string\"},\"failures\": {\"type\": \"string\"},\"queued\": {\"type\": \"string\"},\"delay\": {\"type\": \"string\"}}},{\"type\": \"object\",\"properties\": {\"authServer\": {\"type\": \"string\"},\"requests\": {\"type\": \"string\"},\"failures\": {\"type\": \"string\"},\"queued\": {\"type\": \"string\"},\"delay\": {\"type\": \"string\"}}}]},\"noOfCache\": {\"type\": \"string\"},\"cacheInfo\": {\"type\": \"array\",\"items\": [{\"type\": \"object\",\"properties\": {\"cacheNumber\": {\"type\": \"string\"},\"request\": {\"type\": \"string\"},\"hits\": {\"type\": \"string\"},\"entries\": {\"type\": \"string\"},\"size\": {\"type\": \"string\"},\"ttl\": {\"type\": \"string\"}}},{\"type\": \"object\",\"properties\": {\"cacheNumber\": {\"type\": \"string\"},\"request\": {\"type\": \"string\"},\"hits\": {\"type\": \"string\"},\"entries\": {\"type\": \"string\"},\"size\": {\"type\": \"string\"},\"ttl\": {\"type\": \"string\"}}}]}},\"required\": [\"dispatcherMode\",\"noOfdispatcher\",\"dispatcherInfo\",\"noOfAuthServer\",\"connected\",\"authorizationInfo\",\"noOfCache\",\"cacheInfo\"]}";
jv.validation(jsonData, jsonSchema);
}
public boolean validation(String jsonData, String jsonSchema)
{
ProcessingReport report = null;
boolean result = false;
try{
JsonNode schemaNode = JsonLoader.fromString(jsonSchema);
JsonNode dataNode = JsonLoader.fromString(jsonData);
JsonSchemaFactory factory = JsonSchemaFactory.byDefault();
JsonSchema schema = factory.getJsonSchema(schemaNode);
report = schema.validate(dataNode);
}
catch(Exception ex){
ex.printStackTrace();
}
if (report != null) {
Iterator<ProcessingMessage> iter = report.iterator();
while (iter.hasNext()) {
ProcessingMessage pm = iter.next();
System.out.println("Processing Message: "+pm.getMessage());
}
result = report.isSuccess();
}
System.out.println(" Result=" +result);
return result;
}
}
下面是错误

我解决了之前的错误,但现在却遇到了类似的错误

我没有使用过objectMapper类,但是却遇到了异常。
请参阅堆栈跟踪中的以下部分:
Caused by: java.lang.ClassNotFoundException: com.fasterxml.jackson.core.JsonParseException
at java.net.URLClassLoader$1.run(Unknown Source)
...
它清楚地表明error
是由JVM尝试加载但由于不在类路径中而找不到它JsonParseException
的包的类所引起的com.fasterxml.jackson.core
。
只需将com.fasterxml.jackson.core
jar文件添加到您的类路径中即可。
