我有一个复杂的 json 文件，我需要解析/读取下面的文件并显示它的每个值
{
"spl": "{\"e\":{\"h\":{\"ak\":\"1c8d1d7eaa32ff3f58a882\",\"at\":\"app\"},\"c\":{\"dt\":\"MEmulator\",\"mi\":\"D56BF292F1FC16F\",\"ui\":\"m4J\/2s=\",\"av\":\"0.2\",\"pn\":\"WP\",\"pv\":\"7.10\",\"nv\":\"C# 1.1.0\",\"al\":\"en\"},\"b\":[{\"ts\":139658547,\"tz\":-400,\"s\":\"StartUpScreen\",\"et\":8,\"ev\":\"sessionStart\",\"si\":\"19477682-de55-414f-82c9-19bec331dc33\",\"tt\":{\"DaySessionStarted\":\"Tuesday\"}},{\"ts\":1319549658751,\"tz\":-400,\"s\":\"StartUpScreen\",\"et\":3,\"ev\":\"AutomaticFeedRefresh\",\"si\":\"19477682-de5ec331dc33\",\"tt\":{}},{\"ts\":1319549675609,\"tz\":-400,\"s\":\"MainScreen\",\"et\":3,\"ev\":\"MainScreen Event\",\"si\":\"19477682-de55-414f-82c9-19bec331dc33\",\"tt\":{}},{\"ts\":1319549677179,\"tz\":-400,\"s\":\"MainScreen\",\"et\":3,\"ev\":\"MainScreen Event\",\"si\":\"19477682-de55-414f-82c9-19bec331dc33\",\"tt\":{}},{\"ts\":1319549678401,\"tz\":-400,\"s\":\"MainScreen\",\"et\":3,\"ev\":\"MainScreen Event\",\"si\":\"19477682-de55-414f-82c9-19bec331dc33\",\"tt\":{}},{\"ts\":1319549679973,\"tz\":-400,\"s\":\"MainScreen\",\"et\":3,\"ev\":\"MainScreen Event\",\"si\":\"19477682-c9-19bec331dc33\",\"tt\":{}}],\"tt\":{\"OSV\":\"ME\"}}}",

我开始使用 Jackson pull API，虽然工作量太大，但我发现它更容易......这是我的代码：
import com.fasterxml.jackson.core.JsonFactory;
import com.fasterxml.jackson.core.JsonParser;
import com.fasterxml.jackson.core.JsonToken;
import com.fasterxml.jackson.databind.MappingJsonFactory;
import java.io.File;
public class HugeJson1 {
public static void main(String[] args) throws Exception {
try {
JsonFactory f = new MappingJsonFactory();
JsonParser jp = f.createJsonParser(new File("C:\\json1.json"));
jp.nextToken();
while (jp.nextToken() != JsonToken.END_OBJECT) {
String fieldName1 = jp.getCurrentName();
jp.nextToken();
if ("spl".equals(fieldName1)) {
while (jp.nextToken() != JsonToken.END_OBJECT){
String fieldName2 = jp.getCurrentName();
jp.nextToken();
if("e".equals(fieldName2)){
while (jp.nextToken() != JsonToken.END_OBJECT) {
String fieldName3 = jp.getCurrentName();
jp.nextToken();
if("h".equals(fieldName3)) {
while (jp.nextToken() != JsonToken.END_OBJECT) {
String fieldName4 = jp.getCurrentName();
jp.nextToken();
if("ak".equals(fieldName4)){
jp.nextToken();
System.out.println(jp.getText());
}
else if("at".equals(fieldName4)) {
jp.nextToken();
System.out.println(jp.getText());
}
jp.nextToken();
if ("c".equals(fieldName4)){
while (jp.nextToken() != JsonToken.END_OBJECT) {
String fieldName5 = jp.getCurrentName();
jp.nextToken();
if ("dt".equals(fieldName5)){
jp.nextToken();
System.out.println(jp.getText());
}
else if ("mi".equals(fieldName5)) {
jp.nextToken();
System.out.println(jp.getText());
}
else if ("ui".equals(fieldName5)) {
jp.nextToken();
System.out.println(jp.getText());
}
else if ("av".equals(fieldName5)) {
jp.nextToken();
System.out.println(jp.getText());
}
else if ("pn".equals(fieldName5)) {
jp.nextToken();
System.out.println(jp.getText());
}
else if ("pv".equals(fieldName5)) {
jp.nextToken();
System.out.println(jp.getText());
}
else if ("nv".equals(fieldName5)) {
jp.nextToken();
System.out.println(jp.getText());
}
else if ("al".equals(fieldName5)) {
jp.nextToken();
System.out.println(jp.getText());
}
}
}
}
}
}
}
}
}
}
}catch (JsonGenerationException e) {
e.printStackTrace();
} catch (JsonMappingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
问题是这段代码没有显示任何输出，也没有抛出异常。有人可以帮我找到这个问题吗？
谢谢
