spring boot +mybatis + tk 整合扫描不到mapper.xml的问题解决

直接上代码

 * MybatisConfiguration 主要是配置的sqlSessionFactory和sqlSessionTemplate，以及Mybatis的扩展框架Mapper的配置，如果不需要Mapper，可以不用配置scannerConfigurer

@Configuration

@Slf4j
public class MybatisConfiguration {

    @Bean(name = "sqlSessionFactory")
    @Autowired
    public SqlSessionFactory sqlSessionFactory(DynamicDataSource dynamicDataSource) {
        SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
        bean.setDataSource(dynamicDataSource);
        //因为new了一个SqlSessionFactoryBean 所以yml的mapper-locations的配置没有用，需要手动配置扫描的包
        ResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
        try {
            bean.setMapperLocations(resolver.getResources("classpath:mapping/*.xml"));
        } catch (Exception e) {
            e.printStackTrace();
            throw new RuntimeException(e);
        }
        //分页插件设置(pom.xml 引入了pagehelper-spring-boot-starter 再这里再配置 会配置重复报错)
        /*bean.setTypeAliasesPackage("com.pbh.springbootdemo.model.*");//设置扫描的实体包
        //PageHelper pageHelper = new PageHelper();
        PageInterceptor pageInterceptor = new PageInterceptor();
        Properties properties = new Properties();
        properties.setProperty("helperDialect", "mysql");
        properties.setProperty("reasonable", "true");
        properties.setProperty("supportMethodsArguments", "true");
        properties.setProperty("returnPageInfo", "check");
        properties.setProperty("params", "count=countSql");
        //pageHelper.setProperties(properties);
        pageInterceptor.setProperties(properties);
        //添加分页插件到ibatis拦截器
        bean.setPlugins(new Interceptor[]{pageInterceptor});*/

       //配置通用Mapper
        try {
            SqlSessionFactory session = bean.getObject();
            MapperHelper mapperHelper = new MapperHelper();
            //特殊配置
            Config config = new Config();
            //具体支持的参数看后面的文档
            config.setNotEmpty(true);
            //设置配置
            mapperHelper.setConfig(config);
            // 注册自己项目中使用的通用Mapper接口，这里没有默认值，必须手动注册
            mapperHelper.registerMapper(Mapper.class);
            //配置完成后，执行下面的操作
            mapperHelper.processConfiguration(session.getConfiguration());
            return session;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

    @Bean(name = "sqlSessionTemplate")
    @Autowired
    public SqlSessionTemplate sqlSessionTemplate(SqlSessionFactory sqlSessionFactory) {
        return new SqlSessionTemplate(sqlSessionFactory);
    }

    @Bean
    public MapperScannerConfigurer scannerConfigurer(){
        MapperScannerConfigurer configurer = new MapperScannerConfigurer();
        configurer.setSqlSessionFactoryBeanName("sqlSessionFactory");
        configurer.setSqlSessionTemplateBeanName("sqlSessionTemplate");
        configurer.setBasePackage("com.pbh.springbootdemo.mapper.*");
        configurer.setMarkerInterface(Mapper.class);
        return configurer;
    }
}

主要在这段

 ResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
 try {
     bean.setMapperLocations(resolver.getResources("classpath:mapping/*.xml"));
 } catch (Exception e) {
     e.printStackTrace();
     throw new RuntimeException(e);
 }

后来在tk的gitee上找到了相关文档
https://gitee.com/free/Mapper/wikis/1.3-spring-boot?sort_id=208198

<dependency>
  <groupId>tk.mybatis</groupId>
  <artifactId>mapper-spring-boot-starter</artifactId>
  <version>版本号</version>
</dependency>

注意：引入该 starter 时，和 MyBatis 官方的 starter 没有冲突，但是官方的自动配置不会生效！
