Spring Boot整合SSM

Spring Boot可以帮助我们快速的搭建一个SSM框架，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


2.新建项目，建立相关对应的核心包，下图是成功之后的项目结构图

Students.java

package com.ssm.springboot02.model;

/**
 * @author 小思
 * @PackageName:com.ssm.springboot02.model
 * @ClassName: Students
 * @Description:
 * @date 2018/11/20 12:01
 */
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;

/**
 * @author 小思
 * @PackageName:com.ssm.springboot02.services.Impl
 * @ClassName: StudentsServicesImpl
 * @Description:
 * @date 2018/11/20 12:00
 */
@Service
public class StudentsServicesImpl implements StudentsServices {
    @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;

/**
 * @author 小思
 * @PackageName:com.ssm.springboot02.services
 * @ClassName: StudentsServices
 * @Description:
 * @date 2018/11/20 12:00
 */
public interface StudentsServices {
    public List<Students> getAllStudents();
}

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

StudentsMapper.java

package com.ssm.springboot02.mapper;

import com.ssm.springboot02.model.Students;

import java.util.List;

/**
 * @author 小思
 * @PackageName:com.ssm.springboot02.mapper
 * @ClassName: StudentsMapper
 * @Description:对应Students.xml的接口
 * @date 2018/11/20 12:07
 */
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>

</project>

xml方式pom.xml需要下面的编码，注解方式不需要

第二种方式：注解方式

①删除Students.xml
②pom.xml文件的允许Java文件的xml可编译

StudentsMapper.java(开启注解)
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=1234
spring.datasource.url=jdbc:mysql://localhost:3306/t203?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver


##mybatis配置
mybatis.type-aliases-package=com.ssm.springboot02.model

package com.ssm.springboot02.mapper;

import com.ssm.springboot02.model.Students;
import org.apache.ibatis.annotations.Select;

import java.util.List;

/**
 * @author 小思
 * @PackageName:com.ssm.springboot02.mapper
 * @ClassName: StudentsMapper
 * @Description:对应Students.xml的接口
 * @date 2018/11/20 12:07
 */
public interface StudentsMapper {
    @Select("select * from students")
    public List<Students> getAllStudents();
}

注意：测试的时候在浏览器的地址栏输入

http://localhost:8090/ssm/getStudents

注意配置服务器的端口号和项目的全路径

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

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