MyBatis-Plus 逆向生成tinyint类型的字段对应JAVA类型为boolean

当前使用版本(必填,否则不予处理)

mybatis-plus-boot-starter: 3.4.3.4 mybatis-plus-generator: 3.5.1

该问题是如何引起的？(确定最新版也有问题再提!!!)

问题：数据库设计字段 类型为tinyint，且长度为1时，逆向生成代码后该字段的对应的JAVA类型为boolean， 但本意该字段的类型不是boolean

逆向代码： public static void autoGenerator(String database, String username, String password, String host, String port, String author, String tablePrefix, String parent, String moduleName) {

    String url = "jdbc:mysql://"+ host +":"+port+"/"+ database +"?useUnicode=true&useSSL=false&characterEncoding=utf8";
    String projectPath = System.getProperty("user.dir") + "/src/main/java";

    FastAutoGenerator.create(url, username, password)
            .globalConfig(builder -> builder.author(author)
                    .fileOverride()
                    .disableOpenDir()
                    .outputDir(projectPath))
            .packageConfig(builder -> {
                builder.parent(parent);
                if (StrUtil.isNotBlank(moduleName)) builder.moduleName(moduleName);
                builder.pathInfo(Collections.singletonMap(OutputFile.mapperXml, System.getProperty("user.dir") + "/src/main/resources/mappers/"));
            })
            .strategyConfig((scanner, builder) -> {
                builder.addInclude(getTables(scanner.apply("请输入表名，多个英文逗号分隔？所有输入 all")))
                        .addTablePrefix(tablePrefix)
                        .mapperBuilder()
                        .enableBaseColumnList()
                        .enableBaseResultMap()
                        .build();
            })
            .templateEngine(new FreemarkerTemplateEngine())
            .execute();

}

重现步骤(如果有就写完整)

生成Boolean的相关代码在这： https://github.com/baomidou/generator/blob/develop/mybatis-plus-generator/src/main/java/com/baomidou/mybatisplus/generator/config/converts/MySqlTypeConvert.java#L44 我以前也遇到过类似问题，规避方法是指定为自己写的typeConvert，相关配置：https://baomidou.com/pages/981406/#%E5%8F%AF%E9%80%89%E9%85%8D%E7%BD%AE

你好，为什么添加自己写的typeConvert但是不生效。使用MySqlTypeConvert，debug也不会跳到MySqlTypeConvert中。就好像不是在这里控制的类型转换的一样。 依赖版本:
