创建对象类

package com.example.demo.Hello;

public class User {

    private String name;

    private String address;

    public String getName() {
        return name;
    }

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

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }
}

Java List 操作

package com.example.demo.Hello;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import java.util.ArrayList;
import java.util.List;

@RestController
public class HelloController {

    @RequestMapping(value = "/say", method = RequestMethod.GET)
    public String say() {
        return "hello world";
    }

    @RequestMapping(value = "/users", method = RequestMethod.GET)
    public List<User> getUsers() {

        List<User> users = new ArrayList<>();

        User userA = new User();
        userA.setName("zq");
        userA.setAddress("wuhan");

        User userB = new User();
        userB.setName("zq2");
        userB.setAddress("wuhan2");

        User userC = new User();
        userC.setName("zq3");
        userC.setAddress("wuhan3");

        User userD = new User();
        userD.setName("zq4");
        userD.setAddress("wuhan4");

        users.add(userA);
        users.add(userB);
        users.add(userC);
        users.add(userD);

        return users;
    }
}
