这里有一些示例代码，展示了如何使用 Jackson ObjectMapper 来解析数据。请注意，代码假定数据存储在文件中，您可以根据需要对其进行修改。
这是主类：
package parsing.arrayofarray;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.List;
import com.fasterxml.jackson.core.JsonParseException;
import com.fasterxml.jackson.core.type.TypeReference;
import com.fasterxml.jackson.databind.JsonMappingException;
import com.fasterxml.jackson.databind.ObjectMapper;
public class ArrayOfArray {
public static void main(String[] args) {
ObjectMapper mapper = new ObjectMapper();
String data = null;
try {
data = new String(Files.readAllBytes(Paths.get("src/main/resources/jsonArrayOfArray.json")));
} catch (IOException e1) {
e1.printStackTrace();
}
List<List<CreateDoc>> results = null;
try {
results = mapper.readValue(data, new TypeReference<List<List<CreateDoc>>>(){});
} catch (JsonParseException e) {
e.printStackTrace();
} catch (JsonMappingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
System.out.println(results);
}
}
这里是支持类，首先是 CreateDoc：
package parsing.arrayofarray;
public class CreateDoc {
DocMetData dMetaData;
DocContent dCont;
public DocMetData getdMetaData() {
return dMetaData;
}
public void setdMetaData(DocMetData dMetaData) {
this.dMetaData = dMetaData;
}
public DocContent getdCont() {
return dCont;
}
public void setdCont(DocContent dCont) {
this.dCont = dCont;
}
@Override
public String toString() {
return "CreateDoc [dMetaData=" + dMetaData + ", dCont=" + dCont + "]";
}
}
和文档内容：
package parsing.arrayofarray;
public class DocContent {
@Override
public String toString() {
return "DocContent [data=" + data + "]";
}
String data;
public String getData() {
return data;
}
public void setData(String data) {
this.data = data;
}
}
和 DocMetData：
package parsing.arrayofarray;
public class DocMetData {
String docName;
String docType;
public String getDocNamel() {
return docName;
}
public void setDocName(String docName) {
this.docName = docName;
}
@Override
public String toString() {
return "DocMetData [docNamel=" + docName + ", docType=" + docType + "]";
}
public String getDocType() {
return docType;
}
public void setDocType(String docType) {
this.docType = docType;
}
}
println 的输出是：
[[CreateDoc [dMetaData=DocMetData [docNamel=string, docType=pdf], dCont=DocContent [data=abc]], CreateDoc [dMetaData=DocMetData [docNamel=string, docType=pdf], dCont=DocContent [data=def]], CreateDoc [dMetaData=DocMetData [docNamel=string, docType=pdf], dCont=DocContent [data=ghk]]]]
