使用Eclipse搭建一個簡單的springboot框架

項目結構

1新建Spring Start Project

　　找到File——>New ——>Other…spring start project點擊next新建項目

輸入自己的包名項目名

根據個人情況選擇

 2.配置文件

　　配置默認端口號

server.port=8888

　　配置數據源

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/student?useUnicode=true&characterEncoding=utf8 spring.datasource.username=root spring.datasource.password=root spring.datasource.type=com.alibaba.druid.pool.DruidDataSource

 　　配置掃描包

mybatis.type-aliases-package=com.boot.pojo
mybatis.mapper-locations=classpath:Mapper/*.xml
spring.thymeleaf.prefix=classpath:/template/

　　POM文件

        </plugins>
    </build>

</project>

3.啟動類以及controller

啟動類
@RestController
@MapperScan(basePackages= {"com.boot.Mapper"})
@SpringBootApplication
public class SpringbootApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootApplication.class, args);
    }
}

Controller
@Controller
public class TestController {//controller和SSM的一樣
 @Autowired private TestService testService; //查詢數據 @RequestMapping("/findAll") public String findAll(Model model) { List<TestPojo> list = testService.findAll(); System.out.println("進入方法" + list.get(0)); model.addAttribute("li", list); return "index"; } //測試  @ResponseBody @RequestMapping("/getname") public String userList(@RequestParam(value = "id") String id) { return testService.UserList(Long.parseLong(id)); } //刪除數據 @RequestMapping("/del") public String del(@RequestParam("id") int id) { testService.del(id);//調用service中的del方法 return "redirect:/findAll";//重定向到findAll方法  } //跳轉到添加頁面 @RequestMapping("/addindex") public String del() { return "Add"; } //添加數據 @RequestMapping("/add") public String Add(TestPojo testpojo){ this.testService.Add(testpojo); return "redirect:/findAll"; } //跳轉到數據更新頁面 @RequestMapping("/updateuser") public String Update() { return "update"; } @RequestMapping("/updateselect") public String select(Model model,int id) { TestPojo test =testService.select(id); model.addAttribute("li", test); return "update"; } //更新數據 @RequestMapping("/upda") public String family(TestPojo testpojo ) { System.out.println(testpojo.getAge()); testService.update(testpojo); return "redirect:/findAll"; } }

4.HTML頁面

<body>
    <table border="1" >
        <tr>
            <td>編號</td>
            <td>姓名</td>
            <td>年齡</td>
            <td>入學時間</td>
            <td id="yingcang">地址</td>
            <td colspan="2" >操作</td>
        </tr>
        <tr th:each="list:${li}">
            <td th:text=${list.id} > </td>
            <td th:text="${list.name}"></td>
            <td th:text="${list.age}"></td>
            <td th:text="${list.birthday}"></td>
            <td id="cang" th:text="${list.adress}"></td>
            <td>
                <a th:href="@{/del(id=${list.id})}" > 刪除</a>
            </td>
            <td>
                <a th:href="@{/updateselect(id=${list.id})}">修改</a>
            </td>
        </tr>
    </table>
    <input type="button" value="顯示" onclick="ceshow()" >
    <a th:href="@{/addindex}">增加數據</a>
</body>

剩余接口以及實現類與SSM框架無異
