# 首先用idea创建一个springboot项目 #

### 下一步 选择项目名和一些配置 ###

### 勾选web  Mysql  mybatis ###

### 创建对应的包 ###

### 完事之后我来贴上示例代码 ###

### 实体类 ###

package com.hw.entity;
    
    /**
     * @program: Maven
     * @description:
     * @author: hw
     * @create: 2019-01-04 20:17
     **/
    public class Student {
        private Integer sid;
        private String sname;
        private Integer tid;
    
        @Override
        public String toString() {
            return "Student{" +
                    "sid=" + sid +
                    ", sname='" + sname + '\'' +
                    ", tid=" + tid +
                    '}';
        }
    
        public Student(Integer sid, String sname, Integer tid) {
            this.sid = sid;
            this.sname = sname;
            this.tid = tid;
        }
    
        public Integer getTid() {
            return tid;
        }
    
        public void setTid(Integer tid) {
            this.tid = tid;
        }
    
        public Integer getSid() {
            return sid;
        }
    
        public void setSid(Integer sid) {
            this.sid = sid;
        }
    
        public String getSname() {
            return sname;
        }
    
        public void setSname(String sname) {
            this.sname = sname;
        }
    
        public Student(Integer sid, String sname) {
            this.sid = sid;
            this.sname = sname;
        }
    
        public Student() {
        }
    
    }

### server包下的接口 ###

package com.hw.services;
    
    import com.hw.entity.Student;
    
    import java.util.List;
    
    /**
     * @program: Maven
     * @description:
     * @author: hw
     * @create: 2019-01-04 20:19
     **/
    public interface StudentsServices {
        public List<Student> getAllStudents();
    }

### server包下的impl包下的实现类,记得类上面加上@Server的注解 ###

package com.hw.services.impl;
    
    import com.hw.entity.Student;
    import com.hw.mapper.StudentsMapper;
    import com.hw.services.StudentsServices;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Service;
    
    import java.util.List;
    
    /**
     * @program: Maven
     * @description:
     * @author: hw
     * @create: 2019-01-04 20:20
     **/
    @Service
    public class StudentsServicesImpl implements StudentsServices {
        @Autowired
        private StudentsMapper studentsMapper;
    
    
        @Override
        public List<Student> getAllStudents() {
            return studentsMapper.getAllStudents();
        }
    }

### mapper包下和数据库打交道的类 ###

package com.hw.mapper;
    
    import com.hw.entity.Student;
    
    import org.apache.ibatis.annotations.Select;
    
    import java.util.List;
    
    /**
     * @program: Maven
     * @description:
     * @author: hw
     * @create: 2019-01-04 20:21
     **/
    public interface  StudentsMapper {
        @Select("select * from student")
        public List<Student> getAllStudents();
    }

### controller层的控制类 ###

package com.hw.controller;
    
    import com.hw.entity.Student;
    import com.hw.services.StudentsServices;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    import org.springframework.web.bind.annotation.RestController;
    
    import java.util.List;
    
    /**
     * @program: Maven
     * @description:
     * @author: hw
     * @create: 2019-01-04 21:19
     **/
    @RestController
    public class selectStudentController {
        @Autowired  //注入    完成自动装配
        private StudentsServices studentsServices;
    
        @RequestMapping("/getStudents")
        public List<Student> getAllStudents(){
            System.out.println("集合长度："+studentsServices.getAllStudents().size());
            return studentsServices.getAllStudents();
        }
    
    }

### 然后是整个项目的application.properties ###

#设置端口
    server.port=8091
    #设置访问的链接
    server.servlet.context-path=/hw
    
    spring.http.encoding.force=true
    spring.http.encoding.charset=UTF-8
    spring.http.encoding.enabled=true
    server.tomcat.uri-encoding=UTF-8
    
    
    #配置数据库信息
    spring.datasource.username=root
    spring.datasource.password=root
    spring.datasource.url=jdbc:mysql://localhost:3306/mybatis?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false
    spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
    
    #设置别名
    mybatis.type-aliases-package=com.hw.entity

### 最后是启动类,也就是项目自动帮我们建好的类,我们需要加上一个扫码注解 ###

package com.hw;
    
    import org.mybatis.spring.annotation.MapperScan;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    @MapperScan("com.hw.mapper")    //设置指定要扫描的包
    @SpringBootApplication
    public class SpringbootSsmApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(SpringbootSsmApplication.class, args);
        }
    
    }

### 最后启动我们的项目后访问 ###

### 直接返回的是json数据 ###
