Spring boot 整合mybatis

第一步：创建maven项目并添加spring boot依赖：

<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/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>1</groupId>
  <artifactId>11</artifactId>
  <version>0.0.1-SNAPSHOT</version>
 <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.4.0.RELEASE</version>
</parent>
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies> 
</project>

第二步：添加mybatis依赖

    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>1.1.1</version>
    </dependency>

添加内置的H2数据库

        <dependency>
            <groupId>com.h2database</groupId>
            <artifactId>h2</artifactId>
            <scope>runtime</scope>
        </dependency>

第三步：创建数据库连接XML文件SqlMapConfig.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
    PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
    "http://mybatis.org/dtd/mybatis-3-config.dtd">
    
<configuration>
        
   <environments default = "development">
      <environment id = "development">
         <transactionManager type = "JDBC"/> 
            
         <dataSource type = "POOLED">
            <property name = "driver" value = "com.mysql.jdbc.Driver"/>
            <property name = "url" value = "jdbc:mysql://192.168.1.6:3306/yuanzhen"/>
            <property name = "username" value = "root"/>
            <property name = "password" value = "123"/>
         </dataSource>   
         
      </environment>
   </environments>
  
</configuration>

第四步：创建数据库：

/*
Navicat MySQL Data Transfer

Source Server         : yuanzhen
Source Server Version : 50713
Source Host           : 192.168.1.6:3306
Source Database       : yuanzhen

Target Server Type    : MYSQL
Target Server Version : 50713
File Encoding         : 65001

Date: 2016-08-08 14:52:10
*/

SET FOREIGN_KEY_CHECKS=0;

-- ----------------------------
-- Table structure for STUDENT
-- ----------------------------
DROP TABLE IF EXISTS `STUDENT`;
CREATE TABLE `STUDENT` (
  `ID` int(10) NOT NULL AUTO_INCREMENT,
  `NAME` varchar(100) NOT NULL,
  `BRANCH` varchar(255) NOT NULL,
  `PERCENTAGE` int(3) NOT NULL,
  `PHONE` int(11) NOT NULL,
  `EMAIL` varchar(255) NOT NULL,
  PRIMARY KEY (`ID`)
) ENGINE=InnoDB AUTO_INCREMENT=7 DEFAULT CHARSET=utf8;

-- ----------------------------
-- Records of STUDENT
-- ----------------------------
INSERT INTO `STUDENT` VALUES ('1', 'Mohammad', 'It', '80', '984803322', 'Mohammad@gmail.com');
INSERT INTO `STUDENT` VALUES ('2', 'Shyam', 'It', '75', '984800000', 'shyam@gmail.com');
INSERT INTO `STUDENT` VALUES ('3', 'zara', 'EEE', '90', '123412341', 'zara@gmail.com');
INSERT INTO `STUDENT` VALUES ('4', 'zara', 'EEE', '90', '123412341', 'zara@gmail.com');
INSERT INTO `STUDENT` VALUES ('5', 'zara', 'EEE', '90', '123412341', 'zara@gmail.com');
INSERT INTO `STUDENT` VALUES ('6', 'zara', 'EEE', '90', '123412341', 'zara@gmail.com');

第五步：创建

Student.java

package mybatis;

public class Student {
       private int id;
       private String name;
       private String branch;
       private int percentage;
       private int phone;
       private String email;

       public Student(int id, String name, String branch, int percentage, int phone, String email) {
          super();
          this.id = id;
          this.name = name;
          this.branch = branch;
          this.percentage = percentage;
          this.phone = phone;
          this.email = email;
       }
        
       public Student() {}

       public int getId() {
          return id;
       }
        
       public void setId(int id) {
          this.id = id;
       }
        
       public String getName() {
          return name;
       }
        
       public void setName(String name) {
          this.name = name;
       }
        
       public int getPhone() {
          return phone;
       }
        
       public void setPhone(int phone) {
          this.phone = phone;
       }
        
       public String getEmail() {
          return email;
       }
        
       public void setEmail(String email) {
          this.email = email;
       }

       public String getBranch() {
          return branch;
       }

       public void setBranch(String branch) {
          this.branch = branch;
       }

       public int getPercentage() {
          return percentage;
       }

       public void setPercentage(int percentage) {
          this.percentage = percentage;
       }    
      
    }
