eclipse下整合springboot和mybatis的方法步骤

2019-03-28 11:00 1091 查看

1.新建maven项目

先新建一个maven项目，勾选上creat a simple project，填写groupid，artifactid

2.建立项目结构

3.添加依赖

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.3.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>

<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>
</properties>

<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.3.2</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>

4.代码编写

在包的最外层添加启动类

package com.lee.test;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cache.annotation.EnableCaching;
@SpringBootApplication
@EnableCaching
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}

实体类

package com.lee.test.pojo;

import org.springframework.stereotype.Component;

@Component
public class User {

private int id;

private String name;

private String telephone;

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 String getTelephone() {
return telephone;
}

public void setTelephone(String telephone) {
this.telephone = telephone;
}

}

mapper接口

package com.lee.test.mapper;

import java.util.List;

import org.apache.ibatis.annotations.Mapper;

import com.lee.test.pojo.User;

@Mapper
public interface UserMapper {

List<User> getUser(int id);

}

service接口

package com.lee.test.service;

import java.util.List;

import com.lee.test.pojo.User;

public interface UserService {
public List<User> getUser(int id);

}

service接口实现

package com.lee.test.service;

import java.util.List;

import com.lee.test.pojo.User;

public interface UserService {
public List<User> getUser(int id);

}

controller层

package com.lee.test.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import com.lee.test.pojo.User;
import com.lee.test.service.UserService;

@RestController
public class UserController {

@Autowired
private UserService userService;

@RequestMapping("/getUser")
public List<User> getUser(@RequestParam("id") int id) {
return userService.getUser(id);
}

}

还有mapper.xml的实现

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://www.mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.lee.test.mapper.UserMapper">
<select id="getUser" parameterType="java.lang.Integer" resultType="com.lee.test.pojo.User">
select * from t_user where id = #{id}
</select>
</mapper>

最后是一些配置在application.properties中

spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8
spring.datasource.username=root
spring.datasource.password=root
mybatis.mapper-locations: classpath:mapper/*.xml
