这是异常：
java.lang.NullPointerException

下面是模拟多线程解析sql模板
public class JfinalSqlTest {
private static Template template;
private static String sql;
static{
Engine engine = Engine.use();
// engine.addSharedMethod(new StringUtils());
engine.addSharedMethod(new EngineUtil());
engine.setBaseTemplatePath("E:\\workspace\\demo\\src\\main\\resources\\sql");
template = engine.getTemplate("test.sql");
}
public static void main(String[] args) {
final CountDownLatch count = new CountDownLatch(10000);
try {
ExecutorService threadPool = Executors.newFixedThreadPool(100);
for (int i = 0; i < 10000; i++) {
threadPool.execute(new Runnable() {
@Override
public void run() {
try {
Map map = new HashMap();
map.put("order_pay_type","01");
map.put("channel_id",",WKLC,");
map.put("start_time","2017-12-29 17:58:03");
sql = template.renderToString(map);
// SqlPara sqlPara = SqlUtil.INSTANCE.getSqlPara(sql, map);
// System.out.println("正常解析");
} catch (Exception e) {
e.printStackTrace();
} finally{
count.countDown();
}
}
});
}
threadPool.shutdown();
} catch (Exception e) {
e.printStackTrace();
} finally{
try {
if(count.await(120, TimeUnit.MINUTES)){
System.out.println("处理完成！");
};
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}

我刚更新3.4的代码测试了，private byte[] bytes;
private char[] chars; 这两个变量时全局变量，按照目前这种方式修改还是又问题的，而且出问题的频率比之前还高，我只用2个线程就有问题
