How to send multiple rows of data to Spring Controller
Common requirement would be sending multiple rows of data to Spring Controller.
We use @RequestParam String value to hold the single form field. But when we dealing with multiple rows @RequestParam String value won’t work.
If It is single row like below like below
S.NO | First Name | Last Name | Age |
1 | AAA | BBB | 23 |
We can use @RequestParam annotation to capture the form data:
public String saveEmployee(@RequestParam Integer sNo, @RequestParam String firstName, @RequestParam String firstName, @RequestParam Integer age){ //here we can access the form data. }
Suppose we have a form with multiple rows. Then We have to use @RequestParam String[] values,
Let’s see the example below:
S.NO | First Name | Last Name | Age |
1 | AAA | BBB | 23 |
2 | CCC | DDD | 24 |
3 | EEE | FFF | 28 |
And here is the Controller Code:
public String saveEmployees(@RequestParam Integer[] sNo, @RequestParam[] String firstName, @RequestParam[] String lastName, @RequestParam[] Integer age){ //first row data Integer sNo_0 = sNo[0]; String firstName_0 = firstName[0]; String lastName_0 = lastName[0]; Integer age_0 = age[0]; //second row data Integer sNo_1 = sNo[1]; String firstName_1 = firstName[1]; String lastName_1 = lastName[1]; Integer age_1 = age[1]; //third row data Integer sNo_2 = sNo[2]; String firstName_2 = firstName[2]; String lastName_2 = lastName[2]; Integer age_2 = age[2]; }
