package br.com.devdojo.app.endpoint;

import br.com.devdojo.app.model.Student;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

import static java.util.Arrays.asList;

@RestController
@RequestMapping("student")
public class StudentEndPoint {
    @RequestMapping(method = RequestMethod.GET, path = ("/list"))
    public List<Student> listAll(){
        return asList(new Student("Aluno1"), new Student("Aluno2"));
    }

}

Answer 1

您的 Student 类(class)必须如下所示:

public class Student {

    private String name;

    public Student() {
    }

    public Student(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}
