    解决办法

    修改mapper.xml:

    SpringBoot集成Mybatis时mybatis.mapper-locations和@MapperScan的作用

    之前与数据交互一直使用的ORM框架,新公司使用的是mybatis,现做一些总结。

    1、mybatis.mapper-locations的作用
    mybatis.mapper-locations在SpringBoot配置文件中使用,作用是扫描Mapper接口对应的XML文件,如图中所示:扫描的是resources下的mapper文件夹中所有的xml结尾的文件。
    注:如果全程使用@Mapper注解,可以不使用该配置,即@Mapper可以替代Mapper接口对应的.xml文件,SpringBoot提倡“约定优于配置”。*
    在这里插入图片描述
    我们可以点进去,可以看到是@ConfigurationProperties修饰的类,它的作用是将配置文件中的属性映射到对象中
    在这里插入图片描述
    此处是会将配置文件中以mybatis前缀的属性映射到对应字段上,即将mybatis.mapper-locations通过set方法映射到MapperLocations属性上
    在这里插入图片描述
    在这里插入图片描述
    2、@MapperScan的作用
    @MapperScan写在SpringBoot的启动类上(xxxApplication.java),作用是扫描Mapper接口类。
    在这里插入图片描述
    点进去可以看到@MapperScan会注册BeanDefinition到BeanFactory中,即生成接口对应的实现类。具体怎么实现不在此处赘述,有兴趣可以自行查看源码
    在这里插入图片描述
    @Retention作用是定义被它所注解的注解保留多久
    @Target表明注解的作用目标
    Documented注解表明这个注解应该被 javadoc工具记录
    @Import注解就是之前xml配置中的import标签,可以用于依赖第三方包中bean的配置和加载
    @Repeatable注解表明标记的注解可以多次应用于相同的声明或类型

    ----------------------------------------------------分割线--------------------------------

    总结:
    1、mybatis.mapper-locations在SpringBoot配置文件中使用,作用是扫描Mapper接口对应的XML文件
    2、@MapperScan会扫描Mapper接口类,并生成对应的实现类。

    mybatis-plus今天遇到一个问题,就是mybatis 没有读取到mapper.xml 文件。

    特此记录一下,问题如下:

    org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.husy.mapper.SystemUserMapper.findUserByName
    
        at com.baomidou.mybatisplus.core.override.MybatisMapperMethod$SqlCommand.<init>(MybatisMapperMethod.java:242)
        at com.baomidou.mybatisplus.core.override.MybatisMapperMethod.<init>(MybatisMapperMethod.java:54)
        at com.baomidou.mybatisplus.core.override.MybatisMapperProxy.lambda$cachedMapperMethod$0(MybatisMapperProxy.java:65)
        at java.util.concurrent.ConcurrentHashMap.computeIfAbsent(ConcurrentHashMap.java:1660)
        at com.baomidou.mybatisplus.core.override.MybatisMapperProxy.cachedMapperMethod(MybatisMapperProxy.java:65)
        at com.baomidou.mybatisplus.core.override.MybatisMapperProxy.invoke(MybatisMapperProxy.java:60)
        at com.sun.proxy.$Proxy72.findUserByName(Unknown Source)
        at com.husy.service.impl.SystemUserServiceImpl.findUserByName(SystemUserServiceImpl.java:23)


    错误代码如下:

    mapper.xml 目录(在resources目录中的mapper)

    代码如下:

    单元测试

    @Test
    public void findUser(){
        SystemUser systemUser= systemUserService.findUserByName("admin");
        System.out.println(systemUser.toString());
    }


    mybatis-puls 配置

    @EnableTransactionManagement
    @Configuration
    @MapperScan("com.husy.mapper")
    public class MybatisConfig {
    
        /**
         * mybatis-plus 分页插件
         */
        @Bean
        public PaginationInterceptor paginationInterceptor() {
            return new PaginationInterceptor();
        }
    }


    service实现

    @Service
    public class SystemUserServiceImpl implements SystemUserService {
        @Autowired
        private SystemUserMapper userMapper;
    
        @Override
        public SystemUser findUserByName(String name) {
            return userMapper.findUserByName(name);
        }
    }


    mapper 接口

    @Component
    public interface SystemUserMapper {
        SystemUser findUserByName(@Param("userAccount") String name);
    }


    mapper.xml

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
    <mapper namespace="com.husy.mapper.SystemUserMapper">
        <resultMap id="systemUserMap" type="com.husy.domain.SystemUser" >
            <id column="user_id" property="userId"  />
            <result column="user_account" property="userAccount" />
            <result column="user_password" property="userPassword"  />
            <result column="user_phone" property="userPhone"  />
        </resultMap>
        <select id="findUserByName" resultMap="systemUserMap">
             SELECT
                user_id,
                user_account,
                user_password,
                user_phone
             FROM t_system_user
             where user_account = #{userAccount}
        </select>
    </mapper>


    通过上面的代码可以看出。mapper接口中的方法和映射文件中的方法名称是一样的。不存在名称错误导致的情况,返回值,参数类型等你都正确。如果找不到方法,那一定是映射文件配置问题,只有没有读取到,才会出现找不到的情况。
    我的配置如下:

    问题出错的关键位置
    我这里引用的是 mybatis-plus-boot-starte 依赖

    <dependency>
        <groupId>com.baomidou</groupId>
         <artifactId>mybatis-plus-boot-starter</artifactId>
         <version>3.1.0</version>
     </dependency>


    mapper.xml 的文件引用路径配置如下:

    mybatis.mapper-locations=classpath:mapper/*.xml


    这就导致,mybatis 读取不到 mapper映射文件。

    经过查阅:

    如果引用mybatis-plus-boot-starter 依赖,需要配置 mybatis-plus.mapper-locations
    如果引用mybatis-plus 依赖,需要配置 mybatis.mapper-locations
    如下:

    引用 mybatis-plus 包

    <dependency>
       <groupId>com.baomidou</groupId>
        <artifactId>mybatis-plus</artifactId>
        <version>3.1.0</version>
    </dependency>
    mybatis.mapper-locations=classpath:mapper/*.xml


    引用 mybatis-plus-boot-starter 包

     

    mybatis-plus.mapper-locations=classpath:mapper/*.xml
