配置文件:

1).

package com.warrior.config;

import javax.sql.DataSource;

import org.springframework.boot.context.properties.ConfigurationProperties;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import org.springframework.jdbc.datasource.DataSourceTransactionManager;

import com.alibaba.druid.pool.DruidDataSource;

/**

* 数据源配置

*/

@Configuration

public class DataSourceConfig {

@Bean(name="dataSource")

@ConfigurationProperties(prefix="spring.datasource")

public DataSource dataSource(){

return new DruidDataSource();

}

// 配置事物管理器

@Bean(name="transactionManager")

public DataSourceTransactionManager transactionManager(){

return new DataSourceTransactionManager(dataSource());

}

}

2). MybatisPlusConfig.java:

package com.warrior.config;

import org.mybatis.spring.annotation.MapperScan;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import com.baomidou.mybatisplus.plugins.PaginationInterceptor;

@Configuration

//扫描dao或者是Mapper接口

@MapperScan("com.warrior.mapper*")

public class MybatisPlusConfig {

/**

* mybatis-plus 分页插件

*/

@Bean

public PaginationInterceptor paginationInterceptor(){

PaginationInterceptor page = new PaginationInterceptor();

page.setDialectType("mysql");

return page;

}

}

// 自定义模板配置,可以 copy 源码 mybatis-plus/src/main/resources/templates 下面内容修改,

// mpg.setTemplate(tc);

// 执行生成

mpg.execute();

// 打印注入设置【可无】

System.err.println(mpg.getCfg().getMap().get("abc"));

}

}

生成的文件如下,只要将对应文件拷到项目对应包即可:

下面把对应类展示出来:

.entity-->Student.java

package com.warrior.entity;

import com.baomidou.mybatisplus.enums.IdType;

import com.baomidou.mybatisplus.annotations.TableId;

import com.baomidou.mybatisplus.annotations.TableField;

import com.baomidou.mybatisplus.activerecord.Model;

import com.baomidou.mybatisplus.annotations.TableName;

import java.io.Serializable;

/**

*

*

*

*

* @author lqh

* @since 2018-05-25

*/

@TableName("tb_student")

public class Student extends Model {

private static final long serialVersionUID = 1L;

@TableId(value="id", type= IdType.AUTO)

private Integer id;

@TableField("stu_name")

private String stuName;

@TableField("stu_number")

private String stuNumber;

private Integer age;

public Integer getId() {

return id;

}

public Student setId(Integer id) {

this.id = id;

return this;

}

public String getStuName() {

return stuName;

}

public Student setStuName(String stuName) {

this.stuName = stuName;

return this;

}

public String getStuNumber() {

return stuNumber;

}

public Student setStuNumber(String stuNumber) {

this.stuNumber = stuNumber;

return this;

}

public Integer getAge() {

return age;

}

public Student setAge(Integer age) {

this.age = age;

return this;

}

@Override

protected Serializable pkVal() {

return this.id;

}

}

.mapper-->StudentMapper.java

package com.warrior.mapper;

import com.warrior.entity.Student;

import com.baomidou.mybatisplus.mapper.Bhttp://aseMapper;

/**

*

* Mapper 接口

*

*

* @author lqh

* @since 2018-05-25

*/

public interface StudentMapper extends BaseMapper {

}

mapperXml-->StudentMapper.xml(这个文件要放到src/main/resources/mapper)

id, stu_name AS stuName, stu_number AS stuNumber, age

.service-->IStudentService.java

package com.warrior.service;

import com.warrior.entity.Student;

import com.baomidou.mybatisplus.service.IService;

/**

*

* 服务类

*

*

* @author lqh

* @since 2018-05-25

*/

public interface IStudentService extends IService {

}

.serviceImpl-->StudentServiceImpl.java

package com.warrior.serviceImpl;

import com.warrior.entity.Student;

import com.warrior.mapper.StudentMapper;

import com.warrior.service.IStudentService;

import com.baomidou.mybatisplus.service.impl.ServiceImpl;

import org.springframework.stereotype.Service;

/**

*

* 服务实现类

*

*

* @author lqh

* @since 2018-05-25

*/

@Service

public class StudentServiceImpl extends ServiceImpl implements IStudentService {

}

.controler-->StudentController.java

package com.warrior.controler;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

/**

*

http://* 前端控制器

*

*

* @author lqh

* @since 2018-05-25

*/

@Controller

@RequestMapping("/warrior/student")

public class StudentController {

}

经过以上六步项目已经搭建完成,下面就是写业务代码了,只需要实现controller即可,下面对StudentController.java进行修改:

package com.warrior.controler;

import com.warrior.entity.Student;

import com.warrior.service.IStudentService;

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.ResponseBody;

/**

*

* 前端控制器

*

*

* @author lqh

* @since 2018-05-05

*/

@Controller

@RequestMapping("/warrior/student")

public class StudentController {

@Autowired

IStudentService iStudentService;

@RequestMapping("/hello")

@ResponseBody

public String hello() {

//insert

Student student = new Student()

.setStuName("zhangsan")

.setStuNumber("54")

.setAge(23);

boolean res = iStudentService.insert(student);

return res ? "success" : "fail";

}

}

运行项目,直接访问,搞定!!
