配置：

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.github.pagehelper.PageInterceptor;

@Value("${pagehelper.helperDialect}")
private String helperDialect;

@Bean
public PageInterceptor pageInterceptor() {
PageInterceptor pageInterceptor = new PageInterceptor();
Properties properties = new Properties();
properties.setProperty("helperDialect", helperDialect);
pageInterceptor.setProperties(properties);
return pageInterceptor;
}
}

        fb.setDataSource(dataSource);
        // 该配置非常重要，如果不将PageInterceptor 设置到SqlSessionFfactory中，导致分页失效
        fb.setPlugins(new Interceptor[] {PageInterceptor});

        fb.setMapperLocations(new PathMatchingResourcePatternResolver()

        return fb.getObject();
    }

    @Bean

        DataSourceTransactionManager dataSourceTransactionManager =

配置文件配置

pagehelper.helperDialect = oracle
pagehelper.reasonable = true
pagehelper.supportMethodsArguments = true
pagehelper.params = count=countSql
pagehelper.returnPageInfo = check

使用：
@RequestParam(name="pageNum",required =false,defaultValue="1") int pageNum,
@RequestParam(name="pageSize",required =false,defaultValue="1") int pageSize

PageHelper.startPage( pageNum,pageSize);
