今天遇到一个druid不支持clickhouse的问题,druid执行clickhouse报错:sql injection violation, dbType clickhouse , druid-version 1.2.2, syntax error

错误如下:

	Caused by: java.sql.SQLException: sql injection violation, dbType clickhouse, , druid-version 1.2.2, syntax error: syntax error, error in :'icle r where first_appear_time    <, pos 36, line 1, column 36, token IDENTIFIER r : delete from bd_first_visit_vehicle r where first_appear_time    <   ?;

上面执行sql报错,乍一看还以为是数据源混乱的问题,我的项目是多数据源的,有pg,有clickhouse,上面执行的语句是pg的,是不会报clickhouse的错误的,但仔细看上面的报错信息中有WallFilter.checkInternal方法,它在检查clickhouse sql语法,说我的语句有问题,我看了半天,实在是看不出哪有问题,百度了下看到druid官网有人遇到过这个问题,说是WallFilter在druid版本1.2.3之前不支持clickhouse,我用的druid版本为1.2.2所以我把clickhouse的druid数据源配置中WallFilter删除掉,就不会有问题了。

注释如下:

import com.alibaba.druid.pool.DruidDataSource;

@Configuration

     */

    @Bean("clickHouseDataSource")
    @ConfigurationProperties(prefix = "spring.datasource.clickhouse")

        DruidDataSource dataSource = DruidDataSourceBuilder.create().build();

//        List<Filter> filterList = new ArrayList<>();

        return dataSource;
    }

    @Bean("clickHouseSqlSessionFactory")
    public SqlSessionFactory clickHouseSqlSessionFactory(@Qualifier("clickHouseDataSource") DataSource clickhouseDataSource) throws Exception {
        SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
        bean.setDataSource(clickhouseDataSource);
        bean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath*:/clickhouse/*.xml"));
        Properties properties = new Properties();
        properties.put("dbname", clickHouseDb);
        properties.put("clusterName", clusterName);
        bean.setConfigurationProperties(properties);

        return bean.getObject();
    }

    @Bean
    public SqlSessionTemplate clickhouseSqlSessionTemplate(@Qualifier("clickHouseSqlSessionFactory") SqlSessionFactory clickHouseSqlSessionFactory) throws Exception {
        return new SqlSessionTemplate(clickHouseSqlSessionFactory);
    }

    //配置过滤
//    @Bean
//    public WallFilter ckWallFilter() {
//        WallFilter wallFilter = new WallFilter();
//        wallFilter.setConfig(ckWallConfig());
//        wallFilter.setDbType(DbType.clickhouse);
//        return wallFilter;
//    }
//
//    @Bean
//    public StatFilter ckStatFilter(){
//        StatFilter statFilter = new StatFilter();
//        return statFilter;
//    }
//
//    @Bean
//    public WallConfig ckWallConfig() {
//        WallConfig config = new WallConfig();
//        config.setMultiStatementAllow(true);//允许一次执行多条语句
//        return config;
//    }

}

官方已经发布了druid1.2.4,说是修改了支持clickhouse,但是针对我现在的多数据源场景还是会报如上错误。
