mybtis plus 3.2.0 动态表名sql解析器的配置

一.Configuration

@Configuration
public class MybatisPlusConfiguration {

    public static ThreadLocal<String> inputTableName = new ThreadLocal<>();

    @Bean
    public PaginationInterceptor paginationInterceptor(){
        PaginationInterceptor paginationInterceptor = new PaginationInterceptor();
        List<ISqlParser> sqlParserList = new ArrayList<>();
        DynamicTableNameParser dynamicTableNameParser = new DynamicTableNameParser();
        HashMap<String, ITableNameHandler> map = new HashMap<>();
        map.put("user", (metaObject, sql, tableName) -> inputTableName.get());
        dynamicTableNameParser.setTableNameHandlerMap(map);
        sqlParserList.add(dynamicTableNameParser);
        paginationInterceptor.setSqlParserList(sqlParserList);
        paginationInterceptor.setSqlParserFilter(metaObject -> {
            MappedStatement statement = SqlParserHelper.getMappedStatement(metaObject);
        //如果是selectById方法,则表名不会被替换,其他的会被动态替换表名
return "com.mp.dao.UserMapper.selectById".equals(statement.getId()); }); return paginationInterceptor; } }

二.测试

传入参数

    @Test
    public void testTableNAme(){
        MybatisPlusConfiguration.inputTableName.set("user_2020");
        userMapper.selectList(null);
    }

三.运行结果

 

 可以观察到查询的表名已经被替换
