下面为我的配置
ds = new DruidDataSource();
ds.setDriverClassName("com.mysql.jdbc.Driver");
ds.setUrl(url);
ds.setUsername(user);
ds.setPassword(pass);
ds.setInitialSize(InitialSize); 1
ds.setMinIdle(MinIdle); 1
ds.setMaxWait(MaxWait); 1000
ds.setMaxActive(MaxActive); 10
ds.setKeepAlive(true);
ds.setTestWhileIdle(true); //开启验证连接对象有效性检测
ds.setTestOnBorrow(true);
ds.setTestOnReturn(false);
ds.setValidationQuery("SELECT 'X'");
ds.setValidationQueryTimeout(10 * 1000);
ds.setTimeBetweenEvictionRunsMillis(60 * 1000);
ds.setMinEvictableIdleTimeMillis(30 * 1000);
ds.setRemoveAbandoned(true);
ds.setRemoveAbandonedTimeout(1800);
ds.setLogAbandoned(false);
请问还需要修改或添加什么属性么
