 开发四年只会写业务代码，分布式高并发都不会还做程序员？->>>    @wenshao 你好，想跟你请教个问题： 我是在用activiti工作流的时候  初始化生成流程表产生了下面的问题 工作流引擎代码： ProcessEngineConfiguration config = ProcessEngineConfiguration     .createStandaloneProcessEngineConfiguration();    config.setDataSource(dataSource).setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE).buildProcessEngine(); 报错信息： Caused by: java.sql.SQLException: sql injection violation, syntax error: TODO UNIQUE unique : alter table ACT_RE_PROCDEF  add constraint ACT_UNIQ_PROCDEF  unique (KEY_,VERSION_, TENANT_ID_) at com.alibaba.druid.wall.WallFilter.check(WallFilter.java:724) at com.alibaba.druid.wall.WallFilter.statement_execute(WallFilter.java:396) at com.alibaba.druid.filter.FilterChainImpl.statement_execute(FilterChainImpl.java:2487) at com.alibaba.druid.filter.FilterAdapter.statement_execute(FilterAdapter.java:2451) at com.alibaba.druid.filter.FilterEventAdapter.statement_execute(FilterEventAdapter.java:188) at com.alibaba.druid.filter.FilterChainImpl.statement_execute(FilterChainImpl.java:2487) at com.alibaba.druid.proxy.jdbc.StatementProxyImpl.execute(StatementProxyImpl.java:137) at com.alibaba.druid.pool.DruidPooledStatement.execute(DruidPooledStatement.java:421) at org.activiti.engine.impl.db.DbSqlSession.executeSchemaResource(DbSqlSession.java:1368) ... 32 more Caused by: com.alibaba.druid.sql.parser.ParserException: TODO UNIQUE unique at com.alibaba.druid.sql.dialect.mysql.parser.MySqlStatementParser.parseAlterTable(MySqlStatementParser.java:2375) at com.alibaba.druid.sql.dialect.mysql.parser.MySqlStatementParser.parseAlter(MySqlStatementParser.java:2297) at com.alibaba.druid.sql.parser.SQLStatementParser.parseStatementList(SQLStatementParser.java:217) at com.alibaba.druid.sql.parser.SQLStatementParser.parseStatementList(SQLStatementParser.java:145) at com.alibaba.druid.wall.WallProvider.checkInternal(WallProvider.java:620) at com.alibaba.druid.wall.WallProvider.check(WallProvider.java:574) at com.alibaba.druid.wall.WallFilter.check(WallFilter.java:711) ... 40 more druid版本：1.0.15,1.0.21（测试了这两版本） mysql驱动版本：5.1.32 语句： alter table ACT_RE_PROCDEF  add constraint ACT_UNIQ_PROCDEF  unique (KEY_,VERSION_, TENANT_ID_) 单独拿出来跑是没有问题的 另：我换了HikariCP 没有出现问题，是不是我对Druid的配置出现了问题
