实验： spring-boot 整合 fluent-mybatis 实验过程！！！！

1.参考：

简单整合，会报错误

利用maven编译，

打开目标显示才不会错误。

2. 新建工程

附：idea 建立spring-boot程序抓图：参考连接。  https://www.cnblogs.com/cqmcu/p/15926462.html

添加pom

        <java.version>1.8</java.version>
        <fluent-mybatis.version>1.6.13</fluent-mybatis.version>
    </properties>

        </dependency>

        <!-- 引入fluent-mybatis 运行依赖包, scope为compile -->
        <dependency>
            <groupId>com.github.atool</groupId>
            <artifactId>fluent-mybatis</artifactId>
            <version>${fluent-mybatis.version}</version>
        </dependency>
        <!-- 引入fluent-mybatis-processor, scope设置为provider 编译需要，运行时不需要 -->
        <dependency>
            <groupId>com.github.atool</groupId>
            <artifactId>fluent-mybatis-processor</artifactId>
            <version>${fluent-mybatis.version}</version>

    </dependencies>

    <build>
        <plugins>
            <plugin>

            </plugin>

            <plugin>

            </plugin>
        </plugins>
    </build>

注意，mawen编译插件，没有则有问题。

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>3.1.0</version>
</plugin>

3. application.yml配置

server:
  port: 8080 # 端口号
spring:
  datasource: # 数据库参数配置
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/test_db?useUnicode=true&characterEncoding=utf8
    username: root
    password: 123456

4.  EntityGeneratorTests.java 自动代码生成

package com.example.helloworld;

import cn.org.atool.generator.FileGenerator;
import cn.org.atool.generator.annotation.Table;
import cn.org.atool.generator.annotation.Tables;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
public class EntityGeneratorTests {

    // 数据源 url
    static final String url = "jdbc:mysql://127.0.0.1:3306/test_db?useUnicode=true&characterEncoding=utf8";
    // 数据库用户名
    static final String username = "root";
    // 数据库密码
    static final String password = "123456";

    @Test
    public void generate() {
        // 引用配置类，build方法允许有多个配置类
        FileGenerator.build(Empty.class);
    }

    @Tables(
            // 设置数据库连接信息
            url = url, username = username, password = password,
            // 设置entity类生成src目录, 相对于 user.dir
            srcDir = "src/main/java",
            // 设置entity类的package值
            basePack = "com.example.helloworld",
            // 设置dao接口和实现的src目录, 相对于 user.dir
            daoDir = "src/main/java",
            // 设置哪些表要生成Entity文件
            tables = {@Table(value = {"person"})}
    )
    static class Empty { //类名随便取, 只是配置定义的一个载体
    }

}

5. 利用maven编译

 6.显示target

 7.编译产生代码

8. 产生目标代码

9.添加映射扫描

 10.Controller测试代码编写

@RestController
@RequestMapping("/person")
public class PersonController {
    @Resource
    PersonDao personDao;

    @Resource
    PersonMapper personMapper;

    //数据库的操作：增删改查
    /**
     * 根据ID查询数据1
     * @param id
     * @return
     */
    @GetMapping("/getById")
    public PersonEntity getById(Integer id){
        return personDao.selectById(id);
    }

    /**
     * 根据ID删除
     * @param id
     */
    @GetMapping("/deleteById")
    public void deleteById(Integer id){
        personDao.deleteById(id);
    }

    /**
     * 根据ID进行更新
     * @param personEntity
     * @return
     */
    @PostMapping("/updateById")
    public PersonEntity updateById(@RequestBody PersonEntity personEntity){
        boolean b = personDao.updateById(personEntity);
        if (b){
            return personDao.selectById(personEntity.getId());
        }
        return null;
    }

    /**
     * 新增
     * @param personEntity
     * @return
     */
    @PostMapping("/insert")
    public Integer insert(@RequestBody PersonEntity personEntity){
        return personDao.save(personEntity);
    }

}

11.利用postman工具测试
