Spring Boot配置druid连接池

1.引入包

    com.alibaba
    druid
    1.0.28

2.application.yml中在spring.datasource中增加配置

type: com.alibaba.druid.pool.DruidDataSource

filters: stat,wall,log4j  #stat放到wall前面则统计拦截的时间，stat放在wall后面则不统计拦截的时间

注意：不要同时配置filters和proxyFilters，filter都是内置的，想通过proxyFilters来定制的话，就不要配置filters。

3.连接池druidDataSource

//使用连接池dataSource
@Bean
@ConfigurationProperties(prefix = "spring.datasource")
public DataSource dataSource() {
    DruidDataSource druidDataSource = new DruidDataSource();
    return druidDataSource;
}

4.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;
}
