springboot中配置druid允許一次執行多條sql

1：在配置文件中不需要指定wall防火牆filter。 
配置如下：

spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://localhost:3306/database?zeroDateTimeBehavior=convertToNull&useUnicode=true&characterEncoding=utf-8&allowMultiQueries=true
    username: root
    password: setpay@123
    type: com.alibaba.druid.pool.DruidDataSource
    druid:
      # 初始化連接大小
      initial-size: 8
      # 最小空閑連接數
      min-idle: 5
      #最大連接數
      max-active: 64
      #查詢超時時間
      query-timeout: 6000
      #事務查詢超時時間
      transaction-query-timeout: 6000
      #關閉空閑連接超時時間
      remove-abandoned-timeout: 1800
      # 配置獲取連接等待超時的時間
      max-wait: 60000
      ##配置間隔多久才進行一次檢測，檢測需要關閉的空閑連接，單位是毫秒
      time-between-eviction-runs-millis: 60000
      ##配置一個連接在池中最小生存的時間，單位是毫秒
      min-victable-idle-time-millis: 300000
      validation-query: select 1
      test-while-idle: true
      test-on-borrow: true
      test-on-return: true
      pool-prepared-statements: true
      max-open-prepared-statements: 300
      verify-server-certificate: false
      # 配置監控統計攔截的filters，去掉后監控界面sql無法統計，'wall'用於防火牆
      filters: stat
      # 通過connectProperties屬性來打開mergeSql功能；慢SQL記錄
      connection-properties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
      # 合並多個DruidDataSource的監控數據
      use-global-dataSource-stat: true

 filters里不要配置wall，否則還是報錯

 

 

2：在DruidConfig中進行定制化配置。

@Configuration
public class DruidConfig {

    @ConditionalOnClass(DruidDataSource.class)
    @ConditionalOnProperty(name = "spring.datasource.type",
            havingValue = "com.alibaba.druid.pool.DruidDataSource",
            matchIfMissing = true)
    static class Druid extends DruidConfig{

        @Bean
        @ConfigurationProperties("spring.datasource.druid")
        public DruidDataSource dataSource(DataSourceProperties properties){
            DruidDataSource druidDataSource = (DruidDataSource) properties.initializeDataSourceBuilder()
                    .type(DruidDataSource.class).build();
            DatabaseDriver databaseDriver = DatabaseDriver.fromJdbcUrl(properties.determineUrl());
            String validationQuery = databaseDriver.getValidationQuery();
            if(validationQuery != null){
                druidDataSource.setValidationQuery(validationQuery);
            }
            return druidDataSource;
        }

        @Bean
        public WallFilter wallFilter(){
            WallFilter wallFilter = new WallFilter();
            wallFilter.setConfig(wallConfig());
            return wallFilter;
        }

        @Bean
        public WallConfig wallConfig(){
            WallConfig wallConfig = new WallConfig();
            wallConfig.setMultiStatementAllow(true);//允許一次執行多條語句
            wallConfig.setNoneBaseStatementAllow(true);//允許一次執行多條語句
            return wallConfig;
        }
    }
}
