mybatis常用配置类

@Configuration

public class MybatisConfig {

    public SqlSessionFactory sqlSessionFactoryBean(DataSource dataSource) throws Exception {

        SqlSessionFactoryBean factroy =new SqlSessionFactoryBean();

        factory.setDataSource(dataSource);

        VFS.addImplClass(SpringBootVFS.class) ;

       factory.setTypeAliasesPackage(com.cn.test.bean); //实体包路径

       ResourcePatternResolver resolver =new PathMatchingResourcePatternResolver();

       factory.setMapperLoccations(resolver.getResources("classPath:mapper/*.xml"));

       //配置分页插件

       PageHelper pageHelper =new PageHelper();

       Properties properties =new Properties();

       properties.setProperty("pageSizeZero","true"); //分页尺寸为0时候查询所有记录不再执行分页

      properties.setProperty("reasonable","true"); //页码<=查询第一页 ，页码>=总页数查询最后一页

      properties.setProperty("supportMethodsArguments","true"); // 支持通过mapper接口参数传递分页参数

     pageHelper.setProperties(properties);

     //添加插件

    factory.setPlugings(new Interceptor[ ]{pageHelper});

   try{

           //开启驼峰命名转换

         factory.getObject.getConfiguration.setMapUnderscoreToCameCase(true);

         return factory.getObject();

      }catch(Exception e){

           throw new RuntimeException(e);

      }

}

public MapperScannerConfigurer mapperScannerConfigurer(){

    MapperScannerConfigurer mapperScannerConfigurer =new MapperScannerConfigurer();

    mapperScannerConfigurer.setSqlSessionFactoryBeanName("sqlSessionFactoryBean");

    mapperScannerConfigurer.setBasePackage(com.cn.test.web.dao.mapper);  //存放mapper接口的包路径

    //配置通用mapper

   Properties properties =new Properties();

    properties.setProerty("mappers",com.cin.test.dao.base.mapper);  //mapper插件基础接口的全限定明 此包下的Mapper 继承 BaseMapper,ConditionMapper,IdsMapper,InsertListMapper 接口，如需其他接口可以参考官方文档。

    properties.setProperty("notEmpty","false");

    properties.setProperty("IDENTITY","MYSQL");

    mapperScannerConfigurer.setProperties(properties);

    return mapperScannerConfigurer;
