【Spring Boot】啓動執行activiti時數據庫報錯解決辦法

SpringBoot啓動的時候報瞭如下錯誤：

java.sql.SQLException: sql injection violation, syntax error: syntax error, error in :'cade on update cascade',expect ON, actual ON on : alter table ACT_RU_EXECUTION 
add constraint ACT_FK_EXE_PROCINST 
foreign key (PROC_INST_ID_)

解決辦法

這是由於druid的wallfilter引起的，由於配置中用到的是內置的filter，所以要將內置filter的配置去掉。然後在代碼中直接換成自定義的wallfilter，如下所示：

/**
 * 
 * @Description:自定義設置wallFilter
 * @Author:[email protected]
 * @date: 2017-12-6 下午3:01:13
 * @return
 */
@Bean
public WallFilter wallFilter() {
	WallFilter wallFilter = new WallFilter();
	wallFilter.setConfig(wallConfig());
	return wallFilter;
}

/**
 * 
 * @Description:由於activiti查詢的時候有出現同時兩條語句一次執行的情況，所以自定義一個wallfilter
 * @Author:[email protected]
 * @date: 2017-12-6 下午3:01:34
 * @return
 */
@Bean
public WallConfig wallConfig() {
	WallConfig config = new WallConfig();
	config.setMultiStatementAllow(true);// 允許一次執行多條語句
	config.setNoneBaseStatementAllow(true);// 允許非基本語句的其他語句
	return config;
}
