一、配置pom.xml文件
引入相關的jar包
<!-- springdata和springboot的依賴包 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
整個的pom.xml(根據自身項目所需進行jar包的添加)
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.8.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<java.version>1.8</java.version>
</properties>
<dependencies>
<dependency>

<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<!-- 添加對JSP支持的依賴包 -->
<dependency>

</dependency>
<dependency>

<!-- 支持熱佈署 -->

<!-- 整合mybatis -->

二、定義接口
package com.mingde.dao;
import org.springframework.data.repository.PagingAndSortingRepository;
import com.mingde.po.Student;
public interface StudentDao extends PagingAndSortingRepository<Student, Integer> {
}
三、定義Service層
StudentService
package com.mingde.services;
import java.util.List;
import com.mingde.po.Student;
public interface StudentService {
public List<Student> findAll()throws Exception;
}
StudentServiceImpl
package com.mingde.services.impl;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.mingde.dao.StudentDao;
import com.mingde.po.Student;
import com.mingde.services.StudentService;
@Service
public class StudentServiceImpl implements StudentService {
@Autowired
private StudentDao studentDao;
@Override
public List<Student> findAll() throws Exception {
return (List<Student>) studentDao.findAll();
}
}
四、定義控制層
package com.mingde.controller;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import com.mingde.po.Student;
import com.mingde.services.StudentService;
@Controller
@RequestMapping("/stu")
public class StudentController {
@Autowired
private StudentService studentService;
@RequestMapping("/list")
public ModelAndView list()throws Exception{
List<Student> list = (List<Student>) studentService.findAll();
return new ModelAndView("stu/list", "list",list);
}
}
五、SpringBoot的配置文件:
#配置數據源
spring:
datasource:
driver-class-name: com.mysql.jdbc.Driver
url: jdbc:mysql:///test
username: root
password: 123
#配置SpringMVC視圖
mvc:
view:
prefix: /WEB-INF/
suffix: .jsp
#切換不同的配置文件
# profiles:
# active: dev
#如果當前目錄(resources)及其下面的config目錄中都有application.yml文件
#則config目錄下的優先級要高於當前目錄resources中的優先級
server:
port: 90
六、定義啓動器
package com.mingde;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SpringBootDemo {
public static void main(String[] args) {
SpringApplication.run(SpringBootDemo.class, args);
}
}
