mybatis学习 -每天一记 通用mapper 关于UUID回显的配置

在使用通用mapper插入数据UUID回显

在使用通用mapper插入数据时,发现主键没有回显,我这里的主键是UUID的,解决方案是:配置一个MapperScannerConfigurer.

@Bean
    MapperScannerConfigurer getMapperScannerConfigurer(){
        MapperScannerConfigurer mapperScannerConfigurer = new MapperScannerConfigurer();
        mapperScannerConfigurer.setBasePackage("com.yujiangjun.dao.mybatis.mapper");

        Properties properties = new Properties();
        properties.setProperty("mappers","com.yujiangjun.dao.mybatis.base.BaseMapper");
        properties.setProperty("notEmpty", "false");
        properties.setProperty("IDENTITY","SELECT REPLACE(UUID(),''-'','''')");
        //主键UUID回写方法执行顺序,默认AFTER,可选值为(BEFORE|AFTER)
        properties.setProperty("ORDER","BEFORE");
        mapperScannerConfigurer.setProperties(properties);
        return mapperScannerConfigurer;
    }

说明:我使用的通用mapper是tk.mybatis:mapper.所以在这里导入的tk的MapperScannerConfigurer
