Question

下面是我的RestController类

@RestController
public class EmployeeRestController {

    @RequestMapping(value = "/employees", produces={MediaType.APPLICATION_JSON_VALUE, MediaType.APPLICATION_XML_VALUE})
    public EmployeeList getEmployeesJson() {
        System.out.println("EMPLOYEES");

        return this.getEmployee();

    }
}

这是我的spring-dispatcher-servlet.xml

        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

无论何时击中网址，它都会以xml格式给出响应，但是当基于扩展区分它时，即.xml / .json工作正常。但我想根据参数来区分响应，请帮助

Spring Rest api，根据参数区分响应格式
