springboot(三)整合mybatis

本文整合mybatis根据传统方式,基于注解的方式在上篇博客中

  • 添加依赖

  • 配置build,解决打包时没有xml文件的问题

在pom.xml文件中添加如下内容

<resources>
        <resource>
            <directory>src/main/resources</directory>
        </resource>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.xml</include>
            </includes>
            <filtering>true</filtering>
        </resource>
    </resources>
  • 配置文件
#mybatis的配置
# 需要在resources目录下新建mapper文件夹存放xml
mybatis:
  mapper-locations: classpath:mapper/*.xml
  • mapper接口
Account findAccountById(int id);

对应的xml
<select id="findAccountById" resultType="com.bean.Account" parameterType="int">
        SELECT * from account where id= #{id}
    </select>
  • controller
 @RequestMapping("/findAccountById")
    public Account findAccountById(int id){
        return accountService.findAccountById(id);
    }

结果:{“id”:2,”name”:”bbb”,”money”:1000.0}
