SpringBoot 踩坑实录：PageHelper不生效

试了一晚上，PageHelper一直不生效。最后发生是因为重新定义了SqlSessionFactory但是并没有配置对应的PageHelper插件，所以导致使用PageHelper.startPage(1,1);无效.

 @Bean
    public SqlSessionFactory sqlSessionFactory() throws Exception {

        SqlSessionFactoryBean sessionFactory = new SqlSessionFactoryBean();
        sessionFactory.setDataSource(dataSource);
        sessionFactory.setTypeAliasesPackage("com.lcheng.mango.**.entity");

        PathMatchingResourcePatternResolver resolver=new PathMatchingResourcePatternResolver();
        sessionFactory.setMapperLocations(resolver.getResources("classpath*:**/sqlmap/*.xml"));

        Interceptor[] plugins =  new Interceptor[]{pageHelper()};

        sessionFactory.setPlugins(plugins);

        return sessionFactory.getObject();

    }

重点是这一段：

Interceptor[] plugins =  new Interceptor[]{pageHelper()};

sessionFactory.setPlugins(plugins);
