springboot druid 数据库多SQL错误multi-statement not allow

Caused by: java.sql.SQLException: sql injection violation, multi-statement not allowcom.alibaba.druid.wall.WallFilter.check(WallFilter.java:714) atcom.alibaba.druid.wall.WallFilter.connection_prepareStatement(WallFilter.java:240) atcom.alibaba.druid.filter.FilterChainImpl.connection_prepareStatement(FilterChainImpl.java:448) atcom.alibaba.druid.filter.FilterAdapter.connection_prepareStatement(FilterAdapter.java:928) atcom.alibaba.druid.filter.FilterEventAdapter.connection_prepareStatement(FilterEventAdapter.java:122) atcom.alibaba.druid.filter.FilterChainImpl.connection_prepareStatement(FilterChainImpl.java:448) atcom.alibaba.druid.proxy.jdbc.ConnectionProxyImpl.prepareStatement(ConnectionProxyImpl.java:342) atcom.alibaba.druid.pool.DruidPooledConnection.prepareStatement(DruidPooledConnection.java:318)

解决方案：

1、配置数据库连接，添加allowMultiQueries=true

jdbc.url=jdbc:mysql://192.168.11.107:3306/alarm_db?allowMultiQueries=true&useUnicode=true&characterEncoding=UTF-8

2、如果需要开启wall监控，同时允许multiStatementAllow,就不要在application.yml中配置filter，自己定义

//使用连接池dataSource

@Bean

@ConfigurationProperties(prefix = "spring.datasource")

public DataSource dataSource() {

DruidDataSource druidDataSource = new DruidDataSource();

List filterList=new ArrayList<>();

filterList.add(wallFilter());

druidDataSource.setProxyFilters(filterList);

return druidDataSource;

}

@Bean

public WallFilter wallFilter(){

WallFilter wallFilter=new WallFilter();

wallFilter.setConfig(wallConfig());

return wallFilter;

}

@Bean

public WallConfig wallConfig(){

WallConfig config =new WallConfig();

config.setMultiStatementAllow(true);//允许一次执行多条语句

config.setNoneBaseStatementAllow(true);//允许非基本语句的其他语句

return config;

}
