Java Spring MVC 開發 RESTful API

1.建立一個可以被掃描的Controller

StudentController.java

package com.nsc.platform.common.web;

import org.springframework.web.bind.annotation.*;

/**
 * @author: rc
 * @create: 2019/05/05 17:43
 */
@RestController
@RequestMapping("/api/student")
public class StudentController {
    @RequestMapping(value = "login",method = RequestMethod.GET)
    public String login(String username,String password) {
        if (username == "111" && password == "111"){
            return "true";
        }else {
            return "false";
        }
    }

    @RequestMapping(method = RequestMethod.GET)
    public String Get() {
        return "{\"id\":\"1\",\"name\":\"1111111111\"}";
    }

    @RequestMapping(method = RequestMethod.POST)
    public String Post() {
        return "{\"id\":\"2\",\"name\":\"2222222222\"}";
    }

    @RequestMapping(method = RequestMethod.PUT)
    public String Put() {
        return "{\"id\":\"3\",\"name\":\"3333333333\"}";
    }

    @RequestMapping(method = RequestMethod.DELETE)
    public String DELETE() {
        return "{\"id\":\"4\",\"name\":\"4444444444\"}";
    }

    @RequestMapping(value = "/{id}",method = RequestMethod.GET)
    public String Get(@PathVariable("id") Integer id) {
        return "{\"id\":\""+id+"\",\"name\":\"get path variable id\"}";
    }
}
           

2.實體類

package com.nsc.platform.common.entity;

import com.nsc.platform.common.persistence.DataEntity;

/**
 * @author: rc
 * @create: 2019/05/05 17:45
 */
public class Student extends DataEntity<Student> {
    String name;
    String age;

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

    public String getName() {
        return name;
    }

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

    public String getAge() {
        return age;
    }

    public void setAge(String age) {
        this.age = age;
    }
}
           

通路位址：http://localhost:8080/XXX/api/student

通路位址根據自己項目名修改
