JSON File Connector for JAVA

JSON File Connector can be used to extract and output JSON data stored in local files or direct JSON String (variables or DB columns). JSON Connector also supports JSONPath to filter data from nested array/sub-documents. This Connector is optimized to work with very large files.

In this article you will learn how to quickly and efficiently integrate JSON File data in JAVA. We will use high-performance JSON File Connector to easily connect to JSON File and then access the data inside JAVA.

Let's follow the steps below to see how we can accomplish that!

Create Data Source in ZappySys Data Gateway based on JSON Driver

  1. Download and install ZappySys ODBC PowerPack.

  2. Search for gateway in start menu and Open ZappySys Data Gateway:
    Open ZappySys Data Gateway

  3. Go to Users Tab to add our first Gateway user. Click Add; we will give it a name tdsuser and enter password you like to give. Check Admin option and click OK to save. We will use these details later when we create linked server:
    ZappySys Data Gateway - Add User

  4. Now we are ready to add a data source. Click Add, give data source a name (Copy this name somewhere, we will need it later) and then select Native - ZappySys JSON Driver. Finally, click OK. And it will create the Data Set for it and open the ZS driver UI.

  5. You can use pass single file or multiple file path using wildcard pattern in path and you can use select single file by clicking [...] path button or multiple file using wildcard pattern in path.

    Note: If you want to operation with multiple files then use wild card pattern as below 
    (when you use wild card pattern in source path then system will treat target path as folder regardless you end with slash)
    
    C:\SSIS\Test\reponse.json (will read only single reponse.json file)
    C:\SSIS\Test\j*.json (all files starting with file name)
    C:\SSIS\Test\*.json (all files with .json Extension and located under folder subfolder)
    

  6. Now enter JSONPath expression in Array Filter textbox to extract only specific part of JSON file as below ($.value[*] will get content of value attribute from JSON document. Value attribute is array of JSON documents so we have to use [*] to indicate we want all records of that array)

    NOTE: Here, We are using our desired filter, but you need to select your desired filter based on your requirement.


    Click on Test Connection button to view whether the Test Connection is SUCCESSFUL or Not.

  7. Once you configured a data source, you can preview data. Hit Preview tab, and use similar settings to preview data:
    ZappySys ODBC Driver - Preview JSON Driver

  8. Click OK to finish creating the data source

  9. That's it; we are done. In a few clicks we configured the call to JSON File using ZappySys JSON File Connector

Read data in Java from the DSN

  1. Java code to get the data:

    "jdbc:sqlserver://localhost:5000;databasename=JsonFileDSN;user=tdsuser;password=test"
    Java code to Make ZappySys Driver Data Source Call

  2. When you run the code it will make the API call and read the data:
    Java code ZappySys Driver Data Source Results

  3. Here is Java program's code in text format:

    //Step-2:Assuming the Microsoft SQL Server JDBC Driver is in below folder
    //C:\Program Files\Microsoft Jdbc Driver 6.0 for SQL Server\sqljdbc_6.0\enu\auth\x64
    package padaone;
    
    import java.sql.*;
    
    public class zappy {
    
        public static void main(String[] args) {
    
            // Create a variable for the connection string.
            String connectionUrl = "jdbc:sqlserver://localhost:5000;databasename=JsonFileDSN;user=test;password=test";
    
            // Declare the JDBC objects.
            Connection con = null;
            Statement stmt = null;
            ResultSet rs = null;
    
                try {
                    // Establish the connection.
                    Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
                    con = DriverManager.getConnection(connectionUrl);
    
                    // Create and execute an SQL statement that returns some data.
                    String SQL = "SELECT Country , SUM(UnitPrice * Quantity) Total " 
                               + "FROM value " 
                               + "GROUP BY Country "
                               + "WITH (SRC='https://services.odata.org/V3/Northwind/Northwind.svc/Invoices?$format=json')";
                    stmt = con.createStatement();
                    rs = stmt.executeQuery(SQL);
    
                    // Iterate through the data in the result set and display it.
                    while (rs.next()) {
                        System.out.println(rs.getString(1) + " " + rs.getString(2));
                    }
                }
    
            // Handle any errors that may have occurred.
            catch (Exception e) {
                e.printStackTrace();
            } 
            
            finally {
                if (rs != null) try { rs.close(); } catch (Exception e) {}
                if (stmt != null) try { stmt.close(); } catch (Exception e) {}
                if (con != null) try { con.close(); } catch (Exception e) {}
            }
        }
    }

Conclusion

In this article we showed you how to connect to JSON File in JAVA and integrate data without any coding, saving you time and effort. It's worth noting that ZappySys JSON Driver allows you to connect not only to JSON File, but to any Java application that supports JDBC (just use a different JDBC driver and configure it appropriately).

We encourage you to download JSON File Connector for JAVA and see how easy it is to use it for yourself or your team.
