How to pass array parameters in get request

Mode one

You can pass array parameters multiple times ,springmvc Multiple parameters with the same name will be automatically encapsulated into an array or collection object , Examples are as follows ：

#  request URL
http://127.0.0.1:8080/getUsers?name= Zhang San &name= Li Si 
 
#  Background interface code 
@RestController
@RequestMapping("/")
public class SpringMvcController {
    
 
    @RequestMapping(value = "/getUsers", method = RequestMethod.GET)
    # String[] name You can also switch to List<String,String> name
    public String getUsers(@RequestParam String[] name) {
    
        return name[0] + " " + name[1];
    }
}

Mode two

Directly separate array fingers with commas , Examples are as follows ：

#  request URL
http://127.0.0.1:8080/getTeachers?name= Wang Wu , Liu Mazi 
 
#  Background interface code 
@RestController
@RequestMapping("/")
public class SpringMvcController {
    
 
    @RequestMapping(value = "/getTeachers", method = RequestMethod.GET)
    # String[] name You can also switch to List<String,String> name
