SpringBoot整合SSM框架

Spring Boot可以帮助我们快速的搭建一个[SSM框架][SSM]，那建立spring boot项目之后怎样和SSM整合呢？  
1.新建[Model][]时，选择项目需要的核心依赖包

Students.java

package com.ssm.springboot02.model;
    
    
    public class Students {
        private Integer sid;
        private String sname;
    
        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 Students(Integer sid, String sname) {
            this.sid = sid;
            this.sname = sname;
        }
    
        public Students() {
        }
    }

StudentsServicesImpl.java

package com.ssm.springboot02.services.Impl;
    
    import com.ssm.springboot02.mapper.StudentsMapper;
    import com.ssm.springboot02.model.Students;
    import com.ssm.springboot02.services.StudentsServices;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Service;
    
    import java.util.List;
    
    //放入bean管理
    @Service
    public class StudentsServicesImpl implements StudentsServices {
    //自动注入
        @Autowired
        private StudentsMapper studentsMapper;
    
        @Override
        public List<Students> getAllStudents() {
            return studentsMapper.getAllStudents();
        }
    }

StudentsServices.java

package com.ssm.springboot02.services;
    
    import com.ssm.springboot02.model.Students;
    
    import java.util.List;
    
    
    public interface StudentsServices {
        public List<Students> getAllStudents();
    }

mybatis：

StudentsMapper.java

package com.ssm.springboot02.mapper;
    
    import com.ssm.springboot02.model.Students;
    
    import java.util.List;
    
    
    public interface StudentsMapper {
        public List<Students> getAllStudents();
    }

Students.xml

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
    <mapper namespace="com.ssm.springboot02.mapper.StudentsMapper">
        <select id="getAllStudents" resultType="Students">
            select * from students
        </select>
    </mapper>

3.如果此时启动Springboot02Application文件，因为没有配置application.properties，所以会报错  
此时需要配置项目启动的基本信息

#### 第一种方式：xml方式 ####

application.properties

#服务配置
    server.port=8090
    server.servlet.context-path=/ssm
    
    #数据源配置
    spring.datasource.username=root
    spring.datasource.password=
    spring.datasource.url=jdbc:mysql://localhost:3306/zs?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false
    spring.datasource.driver-class-name=com.mysql.jdbc.Driver
    
    
    #mybatis配置
    mybatis.type-aliases-package=com.ssm.springboot02.model
    mybatis.mapper-locations=classpath:com/ssm/springboot02/model/*.xml

项目application.properties也可以将此文件改为application.yml  
application.yml

selectStudentController.java

package com.ssm.springboot02.controller;
    
    import com.ssm.springboot02.model.Students;
    import com.ssm.springboot02.services.StudentsServices;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    import java.util.List;
    
    
    @RestController
    public class selectStudentController {
    
        @Autowired
        private StudentsServices studentsServices;
    
        @RequestMapping("/getStudents")
        public List<Students> getAllStudents(){
            System.out.println("学生集合长度："+studentsServices.getAllStudents().size());
            return studentsServices.getAllStudents();
        }
    
    
    }

Springboot02Application.java(一定要注意加入MapperScan)

package com.ssm.springboot02;
    
    import org.mybatis.spring.annotation.MapperScan;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    @MapperScan("com.ssm.springboot02.mapper")
    @SpringBootApplication
    public class Springboot02Application {
    
        public static void main(String[] args) {
            SpringApplication.run(Springboot02Application.class, args);
        }
    }
