Spring Boot入门——集成Mybatis

步骤：

1、新建maven项目

2、在pom.xml文件中引入相关依赖

 

    <!-- mysql依赖 -->
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.42</version>
    </dependency>
    
　　<!-- mybatis依赖 -->
    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>1.1.1</version>
    </dependency>

 

3、在application.properties文件中添加配置信息

 

#mysql数据库配置
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/test
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

 

4、编写Grade类

 

package com.wyl.bean;

public class Grade {

    private int id;
    private String gradeNm;
    private int teacherId;
    
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getGradeNm() {
        return gradeNm;
    }
    public void setGradeNm(String gradeNm) {
        this.gradeNm = gradeNm;
    }
    public int getTeacherId() {
        return teacherId;
    }
    public void setTeacherId(int teacherId) {
        this.teacherId = teacherId;
    }
}

Grade class
