在DataSource初始化Bean 添加

List<Filter> proxyFilters = new ArrayList<Filter>();
WallFilter statFilter = new WallFilter();
WallConfig config = new WallConfig();
config.setMultiStatementAllow(true); // 批量操作
statFilter.setConfig(config);
proxyFilters.add(statFilter);
druidDataSource.setProxyFilters(proxyFilters);
