2.5 DDL 统计数据在结构上基本功能安全及

化解新增注记在结构上函数调用，版公布新增 SQL 安全及问题，迄今为止支持 mysql、PostgreSQL。

@Componentpublic class PostgresDdl implements IDdl {/*** 继续执行 SQL CGI方式为*/@Overridepublic List getSqlFiles() {return Arrays.asList(// 可用自带方式为"db/tag-schema.sql",// 元数据绝对路径方式为"D:\db\tag-data.sql");}}

不仅仅可以比较简单继续执行，也可以特性继续执行！！

ddlScript.run(new StringReader("DELETE FROM user;" +"INSERT INTO user (id, username, password, sex, email) VALUES" +"(20, 'Duo', '123456', 0, 'Duo@baomidou.com');"));

它还支持多统计数据采集继续执行！！！

@Componentpublic class MysqlDdl implements IDdl {@Overridepublic void Sharding(Consumer consumer) {// 多统计数据采集选定，主库函数调用从库基本功能同步String group = "mysql";ShardingGroupProperty sgp = ShardingKey.getDbGroupProperty(group);if (null != sgp) {// 主库sgp.getMasterKeys().forEach(key -> {ShardingKey.change(group + key);consumer.accept(this);});// 从库sgp.getSlaveKeys().forEach(key -> {ShardingKey.change(group + key);consumer.accept(this);});}}/*** 继续执行 SQL CGI方式为*/@Overridepublic List getSqlFiles() {return Arrays.asList("db/user-mysql.sql");}}

2.6 特性多统计数据采集于其自由待机

@Sharding 梗概使统计数据采集不限制任意常用待机，你可以在 mapper 层移除梗概，按所需指哪打哪！！

@Mapper@Sharding("mysql")public interface UserMapper extends BaseMapper {@Sharding("postgres")Long selectByUsername(String username);}

你也可以自定方式而确立调兵遣将

@Componentpublic class MyShardingStrategy extends RandomShardingStrategy {/*** 决定待机统计数据采集 key {@link ShardingDatasource}** @param group 特性统计检索分组* @param invocation {@link Invocation}* @param sqlCommandType {@link SqlCommandType}*/@Overridepublic void determineDatasourceKey(String group, Invocation invocation, sqlCommandType sqlCommandType) {// 统计数据采集分组 group 自定选择需， keys 为统计数据采集分组内于其多路由器，可随机选择或者自己依靠this.changeDatabaseKey(group, sqlCommandType, keys -> chooseKey(keys, invocation));}}

可以敞开于其方式而，当然也是可以敞开体检！具体内容可用：

mybatis-mate:sharding:health: true # 健康检测primary: mysql # 除此以外用户选择统计数据采集datasource:mysql: # 统计检索分组- key: node1...- key: node2cluster: slave # 从库算数受控时候负责 sql 检索操纵，主库 master 除此以外用户可以不写出...postgres:- key: node1 # 统计数据路由器...

2.7 分布式外交事务会话存储

均可用如下：

/***

* 安全性分析拦截器，用于反向上面 SQL 语句及其继续执行时间*

*/@Slf4j@Component@Intercepts({@Signature(type = statementHandler.class, method = "query", args = {Statement.class, ResultHandler.class}),@Signature(type = StatementHandler.class, method = "update", args = {Statement.class}),@Signature(type = StatementHandler.class, method = "batch", args = {Statement.class})})public class PerformanceInterceptor implements Interceptor {/*** SQL 继续执行最小时长，少于基本功能停止运行，借以发掘出问题。*/private long maxTime = 0;/*** SQL 是否是模板*/private Boolean format = false;/*** 是否是写出入会话元数据
* true 写出入会话元数据，不阻断程序继续执行！
* 少于设定的最小继续执行时长异常提醒！*/private boolean writeInLog = false;@Overridepublic Object intercept(Invocation invocation) throws Throwable {Statement statement;Object firstArg = invocation.getArgs()[0];if (Proxy.isProxyClass(firstArg.getClass())) {statement = (Statement) SystemMetaObject.forObject(firstArg).getValue("h.statement");} else {statement = (Statement) firstArg;}MetaObject stmtMetaObj = SystemMetaObject.forObject(statement);try {statement = (Statement) stmtMetaObj.getValue("stmt.statement");} catch (Exception e) {// do nothing}if (stmtMetaObj.hasGetter("delegate")) {//Hikaritry {statement = (Statement) stmtMetaObj.getValue("delegate");} catch (Exception e) {}}String originalSql = null;if (originalSql == null) {originalSql = statement.toString();}originalSql = originalSql.replaceAll("[\s]+", " ");int index = indexOfSqlStart(originalSql);if (index> 0) {originalSql = originalSql.substring(index);}// 算出继续执行 SQL 耗时long start = SystemClock.now();Object result = invocation.proceed();long timing = SystemClock.now() - start;// 模板 SQL 存储继续执行结果Object target = PluginUtils.realTarget(invocation.getTarget());MetaObject metaObject = SystemMetaObject.forObject(target);MappedStatement ms = (MappedStatement) metaObject.getValue("delegate.mappedStatement");StringBuilder formatSql = new StringBuilder();formatSql.append(" Time：").append(timing);formatSql.append(" ms - ID：").append(ms.getId());formatSql.append(" Execute SQL：").append(sqlFormat(originalSql, format)).append("");if (this.isWriteInLog()) {if (this.getMaxTime()>= 1 BellBell timing> this.getMaxTime()) {log.error(formatSql.toString());} else {log.debug(formatSql.toString());}} else {System.err.println(formatSql);if (this.getMaxTime()>= 1 BellBell timing> this.getMaxTime()) {throw new RuntimeException(" The SQL execution time is too large, please optimize ! ");}}return result;}@Overridepublic Object plugin(Object target) {if (target instanceof StatementHandler) {return Plugin.wrap(target, this);}return target;}@Overridepublic void setProperties(Properties prop) {String maxTime = prop.getProperty("maxTime");String format = prop.getProperty("format");if (StringUtils.isNotEmpty(maxTime)) {this.maxTime = Long.parseLong(maxTime);}if (StringUtils.isNotEmpty(format)) {this.format = boolean.valueOf(format);}}public long getMaxTime() {return maxTime;}public PerformanceInterceptor setMaxTime(long maxTime) {this.maxTime = maxTime;return this;}public boolean isFormat() {return format;}public PerformanceInterceptor setFormat(boolean format) {this.format = format;return this;}public boolean isWriteInLog() {return writeInLog;}public PerformanceInterceptor setWriteInLog(boolean writeInLog) {this.writeInLog = writeInLog;return this;}public Method getMethodRegular(Class clazz, String methodName) {if (Object.class.equals(clazz)) {return null;}for (Method method : clazz.getDeclaredMethods()) {if (method.getName().equals(methodName)) {return method;}}return getMethodRegular(clazz.getSuperclass(), methodName);}/*** 给予sql语句开头均** @param sql* @return*/private int indexOfSqlStart(String sql) {String upperCaseSql = sql.toUpperCase();Set set = new HashSet<>();set.add(upperCaseSql.indexOf("SELECT "));set.add(upperCaseSql.indexOf("UPDATE "));set.add(upperCaseSql.indexOf("INSERT "));set.add(upperCaseSql.indexOf("DELETE "));set.remove(-1);if (CollectionUtils.isEmpty(set)) {return -1;}List list = new ArrayList<>(set);Collections.sort(list, Integer::compareTo);return list.get(0);}private final static SqlFormatter sqlFormatter = new SqlFormatter();/*** 文件格式sql** @param boundSql* @param format* @return*/public static String sqlFormat(String boundSql, boolean format) {if (format) {try {return sqlFormatter.format(boundSql);} catch (Exception ignored) {}}return boundSql;}}

常用：

@RestController@AllArgsConstructorpublic class TestController {private BuyService buyService;// 统计检索 test 注记 t_order 在外交事务赞同情况下无法断开统计数据，必需断开详述多统计数据采集外交事务作废// 测试者会见 // 所制造外交事务回老家滚 也可通过修改注记在结构上所制造差错// 注释 ShardingConfig 流经 dataSourceProvider 可测试者外交事务作废情况下@GetMapping("/test")public String test(Boolean error) {return buyService.buy(null != error BellBell error);}}

2.8 统计数据司法权

mapper 层移除梗概:

// 测试者 test 种类统计数据司法权范围，结合分页模式@DataScope(type = "test", value = {// 关联注记 user 又叫 u 选定政府机构字符串司法权@DataColumn(alias = "u", name = "department_id"),// 关联注记 user 又叫 u 选定手机号字符串（自己说明解决问题）@DataColumn(alias = "u", name = "mobile")})@Select("select u.* from user u")List selectTestList(IPage page, Long id, @Param("name") String username);

模拟业务范围解决问题逻辑：

@Beanpublic IDataScopeProvider dataScopeProvider() {return new AbstractDataScopeProvider() {@Overrideprotected void setWhere(PlainSelect plainSelect, Object[] args, DataScopeProperty dataScopeProperty) {// args 中构成 mapper 作法的允诺值，需要常用可以而无须给予/*// 测试者统计数据司法权，最终继续执行 SQL 语句SELECT u.* FROM user u WHERE (u.department_id IN ('1', '2', '3', '5'))AND u.mobile LIKE '%1533%'*/if ("test".equals(dataScopeProperty.getType())) {// 业务范围 test 种类List dataColumns = dataScopeProperty.getColumns();for (DataColumnProperty dataColumn : dataColumns) {if ("department_id".equals(dataColumn.getName())) {// 附加政府机构字符串 IN 条件，也可以是 SQL 语句Set deptIds = new HashSet<>();deptIds.add("1");deptIds.add("2");deptIds.add("3");deptIds.add("5");ItemsList itemsList = new ExpressionList(deptIds.stream().map(StringValue::new).collect(Collectors.toList()));InExpression inExpression = new InExpression(new Column(dataColumn.getAliasDotName()), itemsList);if (null == plainSelect.getWhere()) {// 不存在 where 条件plainSelect.setWhere(new Parenthesis(inExpression));} else {// 存在 where 条件 and 解决问题plainSelect.setWhere(new AndExpression(plainSelect.getWhere(), inExpression));}} else if ("mobile".equals(dataColumn.getName())) {// 支持一个自定条件LikeExpression likeExpression = new LikeExpression();likeExpression.setLeftExpression(new Column(dataColumn.getAliasDotName()));likeExpression.setRightExpression(new StringValue("%1533%"));plainSelect.setWhere(new AndExpression(plainSelect.getWhere(), likeExpression));}}}}};}

最终继续执行 SQL 反向：

SELECT u.* FROM user uWHERE (u.department_id IN ('1', '2', '3', '5'))AND u.mobile LIKE '%1533%' LIMIT 1, 10
