@Bean
public SqlSessionFactory sqlSessionFactoryBean(DataSource dataSource) throws Exception {
  SqlSessionFactoryBean factory = new SqlSessionFactoryBean();

  factory.setTypeAliasesPackage(MODEL_PACKAGE);
  //配置分页插件，详情请查阅官方文档
  PageHelper pageHelper = new PageHelper();
  Properties properties = new Properties();
  properties.setProperty("pageSizeZero", "true");//分页尺寸为0时查询所有纪录不再执行分页
  properties.setProperty("reasonable", "true");//页码<=0 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 接口参数来传递分页参数
  pageHelper.setProperties(properties);
  //添加插件
  factory.setPlugins(new Interceptor[]{pageHelper});
  //添加XML目录
  ResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
  factory.setMapperLocations(resolver.getResources("classpath:mapper/*.xml"));
  return factory.getObject();
